IUP - Portable User Interface

History of Changes of Version 1.x


Version 1.9.1 (17/Oct/2002)

General

  • Version number now resides in iup.h (it is also included in the library during compilation.)

Windows

  • IupLabel with \n was not working.
  • Line-break in attribute IUP_TIP is now accepted.
  • Double-click in the Windows top-left corner made the program crash.
  • IUP_READONLY was only accepted if used before IupMap in a IupText or IupMultiline.
  • Windows was limiting initial elements of a IupList to 999.
  • New attribute FULLSCREEN created.
  • The codes of the numeric keyboard when the CapsLock was turned on were not mapped correctly to IUP.
  • New callback added MENUSELECT_CB (called when the mouse hovers over a menu or item.) - not fully implemented.
  • Fixed IupList ACTION callback calls for pre-selected items on the first selection change.

Motif

  • IUP_MOTFONT did not accept IUP fonts. Now it accepts both native fonts and IUP fonts.
  • It is acceptable now to select an option in a popup menu with any mouse key.
  • Attribute IUP_STATUS in a filedlg was not working in a silicon.

IupLua

  • Better error messages.
  • In the iuptree control, the callback BRANCHOPEN_CB was not passing the node parameter.
  • In the iuptree control, new functions were implemented to associate and retrieve a Lua Table from a node or leaf.
  • IupGLCanvas binding.

IupTree

  • Expand and collapse no more alters selection of elements.
  • When all nodes were deleted using "DELNODE0", "CHILDREN" inside a tree_selection callback, the program crashed.
  • BRANCH_OPEN now passes parameter node.
  • IUP_DEPTH now works for folders and leaves. Attention: the depth works only with the appointed element, not with its children.
  • Some conditions necessary for a DEPTH change were wrong.
  • Redraw optimization.
  • When a tree was big, the scrollback was not working properly.
  • When the tree was totally expanded and the scrollbar was all down, collapsing folders made the thumb be wrongly calculated.
  • PGDN and PGUP were stopping in any folder that was closed.
  • Even when the user did not want a folder or leaf to be selected, sometimes the tree allowed it.
  • When the tree's folder does not have children, an empty box is shown next to it (instead of the + and - symbol.)
  • Sometimes an error occurred in selection when a double click was done in a tree.
  • Callback RENAMENODE_CB now works correctly.
  • When the TreeSetValue function was used to define a tree, using a folder with no leaves made the program crash.
  • New attribute "COLORid" allows the text color to be changed.

IupTabs

  • IUP_REPAINT was not repainting the elements in its interior.

IupMatrx

  • The attributes IUP_DEFAULTESC and IUP_DEFAULTENTER of a dialog were not working in Windows (they work only when the matrix is not in edition mode.)
  • The matrix did not show the selected elements when the focus passed to another interface element.
  • In a dropdown, when the user left edition mode changing the focus away from the matrix, the previously entered value was lost.
  • Selection with the control key now works for selecting and deselecting.
  • The cell with the input focus now draws the selection status.
  • The attribute IUP_MARKED now works after the matrix is mapped.
  • The matrix now starts with no cell selected.
  • Clicking on the first column of a marked line with MARK_MODE LIN now also deselects the line.
  • When MARK_MODE is LIN, COL or LINCOL the selection is not done on the focused cell.
  • When MARK_MODE is CELL and MULTIPLE is NO the whole line cannot be marked.
  • When MARK_MODE is NO nothing can be selected.
  • The [TAB] key in the matrix now changes focus to next element.
  • When MARK_MODE was NO (default), after leaving the edition mode with [ENTER] the cell was being marked.

IupVal

  • Mousemove is now standardized.
  • Idle is not used anymore (better optimization and code simplicity.)

  • Clicking a position in the middle of the IupVal now work correctly.

Version 1.9.0 (18 Dec 2001)

General

  • The K_ANY callback now considers the state of the CAPSLOCK key. The native behavior of the combination of the keys CAPSLOCK and SHIFT was kept.
  • New binding for IUP: Lua 4.0.
  • New binding for IupMask.

Windows

  • Driver Windows now deals only with messages generated for IUP elements (this used to be a problem with CD's print dialog).
  • Label fonts did not work when set before IupMap.
  • Attribute IUP_FILTERUSED now can be set on before the creation of IupFileDlg. 
  • Tip in Windows now accepts \n.
  • Tip in Windows is now modified immediatly after it is set though programming.
  • Tip now can be removed immediatly.
  • In a SubMenu, the attribute ACTIVE was not working propertly.
  • The OPEN_CB callback was implemented in the SubMenu.

Motif 

  • Callback OPEN_CB in a SubMenu was providing wrong parameter.
  • Attribute  IUP_BORDER in a dialog was working differently from the manual when the window manager was sawfish.

iupMask

  • iupMask was becoming unstable when the user set the attribute IUP_SELECTION in a IupText.
  • There was a bug in the IupMask-IupMatrix combination.

IupMatrx

  • Adding a new column or line is now correctly dealing with color inheritance. 
  • There was IUP_MARK_MODE defined but not: IUP_LIN, IUP_COL, IUP_LINCOL and IUP_CELL.
  • The drop_cb callback was being called for any focus change. It is now being called just when the matrix enters edition mode.
  • The matrix was not showing the selected cells when the user changed focus from the matrix.
  • The matrix was not calling K_ANY from the parent if the callback had been set after matrix creation.
  • IUP_RIGHTCLICK_CB is now called IUP_CLICK_CB. This callback is now called for every mouse button.
  • New callback IUP_MOUSEMOVE_CB.

IupTree

  • Attribute IUP_MARKED now also sets.
  • IupTree's binding now exports functions to set and get ID.
  • Redraw is now done with one attribute. This avoids unecessary redraw when the user wants to insert a lot of data. 
  • IupTree now takes leafs and nodes before IupMap.
  • Clicking to select a  LEAF was not always working in Windows.
  • BRANCHOPEN and BRANCHCLOSE callbacks were not testing the return value correctly.
  • Double clicking was not working propertly. When the user clicked a node, while the timer was still waiting for the second click, it was impossible to click a nother node.
  • Hitting the space button with CTRL pressed now marks the element immediatly.
  • SELECTION_CB callback was created. This callback is called when any type of mark is made on the Tree. The return value blocks this action.

  • Setting IUP_VALUE though programming does not activate callbacks anymore.
  • Keyboard control, including arrow keys, PGUP, PGDOWN, HOME e END were not working propertly.
  • Clicking + or - was not activating the SELECTION_CB callback.
  • SELECTION_CB is now in the binding. BEFORESELECTION_CB and AFTERSELECTION_CB are not.
  • The IUP_MARKEDid attribute now returns IUP_YES or IUP_NO depending on the state of the node's mark. If the node does not exist, the returned value is NULL.
  • IupTree was breaking when it tried to erase a marked node inside BRANCHCLOSE_CB.
  • The BRANCHCLOSE_CB callback was not being called for the correct node.
  • SELECTION_CB was included in the binding.
  • Including a new leaf now does not alter selection.

IupGL

  • Created attribute "ERROR" indicating error in a GL canvas.

IupCB

  • User canvas was not being reactivated after the mouse callbacks.

IupLua

  • IupGetGlobal and IupSetGlobal were not doing toupper.
  • New function created to get an Ihandle created in C: IupGetFromC.
  • The IUP_BUTTON_CB callback was not being called.
  • Functions isshift, iscontrol, isbutton1, isbutton2, isbutton3 and isdouble are now exported.
  • IupPreviousField and IupNextField were not implemented.
  • The OPEN_CB callback was implemented in the binding with the name OPEN.
  • New callback IUP_MOUSEMOVE_CB for matrix.

Version 1.8.9 (07 May 2001)

IupMatrx Control 

  • If the user defined FGCOLOR while the matrix was in edition mode, the application crashed.
  • Hitting Esc was causing garbage to be written in the matrix field.
  • A bug that made the value_edit callback be called several times was fixed (it was called several times because the matrix kept trying to exit the edition mode with other events).

IupTree Control 

  • New IupTree control.
  • Scrollbar.
  • Multiple selection.
  • Default image size: 16x16.
  • Lua Binding.

IupCB Control 

  • The name of the Lua colorbrowser element has changed. Now it is called iupcb, not cb.

Windows 

  • The IUP_MULTIPLEFILES attribute was created. Now it is possible, in Windows, to select several files in a FileDlg.
  • IupHelp now only initializes DDE when it is used.

Version 1.8.8 (15 Mar 2001)

  • The global.h, macros.h, rgb.h and hls.h files are no longer exported by IUP.
  • Some keys were in conflict among themselves (shift-home and 4, for instance). Shift-space and Ctrl-space were added to the K_ANY callback (Windows and Motif).
  • IUP_VISIBLE was returning NULL on IUP when the dialog was not mapped.
  • IupSetLanguage can now be called before IupOpen();
  • iuptoolbar and iupfiletext were removed from the distribution.

CPI

  • Several defines (such as strieq) are no longer exported from iupcpi.h
  • Functions iupAddSymbol, iupGetSymbol, iupgetdata and iupsetdata are no longer exported from the CPI.

Motif 

  • The Tip font is now inherited from the element it belongs.
  • Inserting a text (IUP_INSERT or IUP_APPEND) on Motif was ignoring the maximum number of characters.
  • Some ITALIC fonts were not working.
  • Several visibility problems were fixed for ZBOX inside a ZBOX.
  • The default value of the ALLOWNEW attribute (in fileopen mode) allowed creating a new file (now standardized).

IupTabs Control 

  • IupTabs was not considering attribute IUP_ALIGNMENT.
  • Tabs was not showing the selected element if it was selected while the Tabs was invisible (it was a Motif bug).
  • The <TAB> key was neither passing the focus to IupTabs nor taking the focus off it.
  • The SIZE attribute is now defined for the tabs of IupTabs ICTL_TABSIZE.
  • Changing the text value for Tabs was not recomputing the Tabs size.
  • The appearance of IupTabs was enhanced.
  • IupTabs now sends the focus back to the first element when the user tries to shift right after the last element.
  • Now a redraw can be forced on Tabs with the IUP_REDRAW attribute.

IupMatrx Control 

  • Ctrl+arrows was not working properly.
  • The behavior of the DEL key to delete a set of cells now also considers the return of the IUP_EDITION_CB callback.
  • The mark is now shown (not the focus) when matrx loses the focus (users were having problems when wishing to hit a button to cause an action over the matrix).
  • Oh the NT platform, the fields of the created matrix had the wrong values when an automatic scroll occurred.
  • Right-clicking the matrix now passes the control parameter (as in BUTTON_CB) isshift(r), iscontrol(r), isbutton1(r), isbutton2(r), isbutton3(r), isdouble(r) 
  • Vertically scrolling by dragging the thumb now works properly.
  • The focus is now correctly drawn inside the matrix (when only half the cell appears, half of the focus is drawn).
  • When leaving the edition mode by clicking an element outside the matrix, the focus was remaining on the IupText in the matrix.
  • Colors and alignments are now moved when a cell is moved either by adding new lines or columns or by deleting lines or columns.
  • The matrix now leaves the edition mode whenever lines or columns are removed.
  • When the user clicked a cell near the end of the matrix (on the x coordinate) an automatic scroll was made and the cell beside the desired cell was marked.

Windows 

  • KEY in IupItem was replicating the underlined KEYs (and some times adding the wrong values because of that).

IupLua.exe

  • Now works properly with all controls.

IUP Manual 

  • All elements now have examples at least in IupLua and C.
  • The IupMask manual was created.

Version 1.8.7 (23 Nov 2000)

  • The alignment of composition elements can now be changed on-the-fly.
  • Current language treatment has been changed. ATTENTION: previous putenv no longer works! Use new functions IupSetLanguage and IupGetLanguage. Default language: Portuguese.
  • IupAlarm's design was reformulated. Now all buttons have the same size.
  • Functions IupUnMapFont and IupMapFont were created to make the use of the drivers fonts easier.
  • Attribute IUP_FONT now accepts a string either with the native font or the IUP font, and always returns the native font (attributes WINFONT and MOTFONT are now obsolete).

Motif 

  • Motif did not have K_ANY for IupList in dropdown mode.
  • The IUP_VISIBLE attribute now works for FRAME, ZBOX, VBOX, HBOX and RADIO (all elements were tested). Now it is no longer lost for internal HBOX elements when the HBOX visibility is changed.
  • When the user changed from one ZBOX to another, the first one was forgetting which elements were visible.

Windows 

  • When Toggle 1 (default) begins deactivated, it no longer remains marked forever.
  • Toggle with image now accepts images IUP_IMPRESS and IUP_IMINACTIVE, but it follows the Windows standard for Toggle manipulation.
  • Toggle was not verifying whether it was active or not when it was created.
  • Canvas redraw was optimized. The canvas now uses transparent color as default. The user is in charge of drawing the canvas, but now it no longer blinks when a redraw is made. Tip: To avoid unnecessary canvas redraws, do not put it inside a frame and use the IUP_CLIPCHILDREN attribute.
  • Initializing Toggle (or Radio) with a value and then modifying it via callback was marking both toggles.
  • Changing Toggles color (IUP_FGCOLOR) was not working on Windows unless its background color was also changed.
  • IupItem outside a submenu was not calling the callback.
  • On Windows, the IUP_HOTSPOT attribute was being read incorrectly (the correct form is with ":").

IupMatrix Control 

  • DROPDOWNs function in Matrix was corrected. Now the user fulfills the dropdown values, which always start at position 1. If the user wishes, he/she can set the initial dropdown value by checking the IUP_PREVIOUSVALUE attribute about the dropdown element passed as parameter. This attribute returns the previously selected string value.
  • Dropdown now enters edition mode just as regular fields do.
  • Dropdown can automatically close after the users choice. Simply return IUP_CONTINUE for the callback chosen by the dropdown.
  • Now the dropdown accepts the ESC key, restoring its previous value.
  • An element with focus is now drawn with double focus.
  • The color of a selected element is now 20% attenuated.
  • When the user entered edition mode using the mouse and exited it hitting ENTER, the cell remained selected.
  • Matrix no longer gets lost when it has 0 lines.
  • Matrix was not accepting a user to return a constant string with \n from a callback.
  • A Matrix that loses the focus does not lose the selection (but it is not apparent).
  • TAB no longer changes cells in the Matrix (it now changes IUP elements).
  • Hitting delete on a marked element deletes everything.
  • Matrix leaves the edition mode when IupTexts exit arrows are used.
  • There was a computation mistake in cell size when the Matrix was in edition mode.
  • When the user scrolls, the Matrix exits the edition mode.
  • ALL problems caused by cdActivate in Matrix were solved.

Other Extended Controls

  • The element from IupGL was not getting the focus when it was the only element in the dialog.
  • In IupGL, OpenGL now synchronizes its functioning with Motif (glXWaitX) at resize.
  • IupGC now works with IUP_ENGLISHs variable set (cancel/cancela, red/Verm, etc.)
  • IupGauge now accepts changing text or percentage values on-the-fly.
  • Tabs font now has a differentiated color when it is inactive.

IupLua

  • IupScanf at IupLua was not performing the final dialogs popup.
  • IupSetLanguage, IupGetLanguage, IupMapFont and IupUnMapFont were created at IupLua.
  • It now considers the IUPLUA_QUIET attribute.
  • The callbacks in IupLua are now inherited (eg.: k_any from a dialog is called when IupCanvas does not have k_any).
  • The librarys opening message now follows a standard.
  • IupLua was passing Luas pointer to IUP instead of copying its value in IupSetHandle (making it crash).

IupLua Program

  • iuplua was not running with IupVal and IupGetColor.
  • iuplua now accepts several files as a parameter.
  • iuplua is now joined with iupluafull
  • iuplua now shows line number and cursor column.

Version 1.8.6 (21 Jun 2000)

  • All libraries were generated for AIX 4.3.2, which is available in new IBM machines.
  • A series of memory management problems was solved for all platforms.
  • Attribute IUP_SELECTEDTEXT now can also be used to change the selected text in a IupText and IupMultiline field.
  • The IupLabel element now takes the IUP_ALIGNMENT attribute into account.
  • The IupList (dropdown) element now always leaves some option selected (unless there is none to select).
  • When the selected elements value in IupList (dropdown) is changed, it now remains selected with the new value.

User Manual

  • The user manual is now also available in several Windows Help formats, including the help format for Visual C++ (5 and 6). To configure your account for Visual C++ to access IUPs Help, run W:\iup\help\iuphelp.reg (ATTENTION: On Visual Studio, IUPs manual must be activated and deactivated through option Help -> Use extension Help). Other available formats can be found at W:\iup\Help.
  • A general revision of the user manual is being made.
  • The CPI manual was rewritten.
  • Several examples were included.
  • An application called iupluatest (W:\iup\bin) was created to run the IupLua examples included in the manual (it works with the controls using the installed DLLs).

Windows 

  • There is no longer any restriction for the number of dialogs created using IUP (the only limitation now is Windows capacity to create native elements).
  • Events of IupButton and IupToggle were being improperly called when a IupHide or a IupShow was made on the dialog.
  • A bug when drawing an image associated to a IupToggle element was fixed.
  • The functioning of attributes IUP_DEFAULTENTER and IUP_DEFAULTESC was corrected.
  • Now, when a user changes the selection of a multiple IupList via programming, IUP internally updates the selection.
  • The IUP_BGCOLOR attribute to define a new cursor was not standardized with the Motif, and color 0 in the Windows image was never allowed to be transparent.
  • A bug in the dropdown list was fixed. It was not calling callback GETFOCUS_CB, causing instability in the IupMatrix element).
  • The transparency color in a cursor now must be color number 0 (according to the manual, this is the way it was supposed to be).
  • The IupList (dropdown) callback is no longer called for element 0 (which does not exist).
  • A button in a Popup dialog was only allowing to be pressed via mouse. Now it can be pressed with the space key.
  • The IupSetAttribute(x,IUP_VISIBLE,IUP_YES) call, when x was a dialog, was not working.
  • Calling IupHide with a frame, with [hvz]box or with radio was not the same thing as calling IupSetAttribute(n,IUP_VISIBLE,IUP_NO)".
  • The IUP_MOUSEPOS position in a dialogs IupPopup was not functioning.

Motif 

  • Several memory leaks were fixed. They occurred when IupGetAttribute called functions from XM which allocated memory to store the attributes value. This change may cause problems for applications which did not copy the value returned from IupGetAttribute and used the returned string. This usage of the return value from IupGetAttribute is not appropriate, because the user has to copy this string if he/she intends to remain using it (the returned string is intern to IUP).
  • The dialog's Close callback was not closing the application when it returned IUP_CLOSE.
  • The IUP_ACTION callback from IupMultiline was not returning the new text value if the key was validated (parameter after).
  • The dropdown list was not automatically showing the first element when it was opened.
  • The Motif now returns the default font when IupGetAttribute(n,IUP_FONT) is performed.

IupLua

  • The names of callbacks show_cb and map_cb were corrected.
  • A bug that made a toggle image not appear was fixed.

Extended Controls

  • The default cursor of the IupMatrix element now looks like the MS Excel cursor. (Remember to call IupMatrixOpen() even when using IupLua!)
  • Alignment (center) of the field in column 0 of the IupMatrix element.
  • The user can now return IUP_CONTINUE at the action callback of element IupMatrix to allow IUP to go on treating pressed keys in the conventional IUP way.
  • The dropdown list at IupMatrix was losing its current value when the user changed cells.
  • The IupGetColor element was being drawn outside the canvas (old problem in cdActivate).
  • The font in IupTabs is now inherited.
  • Attributes ICTL_ACTIVE_FONT, ICTL_INACTIVE_FONT, ICTL_FONT were implemented in the IupTabs element.
  • Attribute IUP_MARGIN was implemented for the IupGauge element.

Version 1.8.5 (18 Apr 2000)

  • The versions of libraries IUP and IupLua were synchronized. From this version on, these tools will be distributed together.
  • The library generation mechanism was changed to use libmake. All DLLs are available and following the same standard as the DLLs of other Tecgraf libraries.
  • A FAQ was created for IUP: http://www.tecgraf.puc-rio.br/~mark/iup/faq-iup.txt.
  • Several memory management problems were fixed.
  • Attribute IUP_DIALOGTYPE can now assume three values: IUP_OPEN, IUP_SAVE and IUP_DIR. Due to the creation of IUP_DIR, the IUP_ALLOWDIR attribute is no longer used.
  • One more value was added to attribute BGCOLOR: IUP_TRANSPARENT (used only by the Canvas to avoid unnecessary drawing).
  • Function IupGetError was removed from iup.h.
  • Function IupDataEntry was removed from iup.h.

Windows 

  • Function iupdrvSetIdleFunction was added to make the Windows compatible with Motif.
  • The bug that made IUP crash when using MessageBox inside a button callback was fixed.
  • IupDestroy now reconfigures the button control function (it was making IUP crash).
  • The IUP_READONLY attribute was implemented (valid for Text and Multiline).
  • The IUP_FILTERUSED attribute was implemented: it informs which is the filter selected by the user (1, 2, 3...).
  • A bug that caused IupPopup(IupMenu(item)) not to call the items callback was fixed.

Motif 

  • IupDestroy was corrected. In a IupFrame, it made IUP crash.
  • IupList was corrected. It crashed when the user changed its elements and tried to set IUP_VALUE.
  • The memory leak at IupGetFile was removed.
  • List elements were not being correctly deleted.

IupMatrix Element 

  • The bug in the NT matrix was fixed. It was not refreshing added elements (the values on the cells were wrong).
  • The bug in the scroll matrix was fixed.

Version 1.8.4 (09 Dec 1999)

Windows 

  • A problem, which called the dropdown callback even for an already-deleted element, was fixed.
  • Function IupHelp is now available.
  • A bug was fixed; it caused excessive system resource usage when dialogs with several elements were used.
  • The size of the version dialog was corrected.
  • A bug was fixed; it made IUP crash depending on the use of MessageBox. Same for IupFileDialog.
  • Callback IUP_BUTTON_CB was added for the IupButton element.
  • A bug was fixed; it made IupGetInt(d,IUP_X) return a wrong value when the dialog was maximized.

CPI Controls 

  • The color inheritance problem was fixed.
  • Corrections were made to the Dial size.
  • Attributes of colors FGCOLOR, BGCOLOR, and fonts FONT, WINFONT, MOTIFFONT.

Version 1.8.3 (15 Jun 1999)

Windows 

  • The IUP_ACTIVE attribute now also works in the frame.
  • The action callback in Multiline now also accepts the DEL key.
  • Toggle element now accepts an image.
  • The IUP_TOOLBOX attribute was implemented for dialogs.
  • A bug was removed; it made a second IupShow in a dialog reset its position to the center of the screen.
  • Treatment of the SIZE and RASTERSIZE attributes was changed.
  • The IUP_ACTION callback now treats the DEL key and commands and keys from the Cut and Paste menu.
  • A conflict was solved; it made the key - generate a call to the callback as if it were key (plic).
  • Keyboard accelerators for menus now work, since the focus is no longer on the dialog. When a dialog receives the focus back, it sets the focus to the last control inside it that had the focus.
  • IUP_K_ANY no longer issues beeps when keys are pressed on the canvas.
  • When the IUP_STARTFOCUS attribute is not defined, the focus is set for the first control in the dialog that accepts it, thus preventing the dialog from keeping the focus and allowing the menus to be called via accelerator.
  • Attribute IUP_SELECTION was implemented.

Motif 

  • Color management for 8bpp displays (256 colors) was re-implemented. Basic colors used by IUP (black, white and the grays used for highlight and shadow) are now reserved, and the search for colors in the palette was optimized.
  • Elements such as IupCanvas now have their own visual, independent from their parents. If allowed by the display, the default visual of a canvas will be TrueColor (24bpp); if not, it will be the same as the default display visual.
  • The IupToggle element now processes the IMAGE attribute differently: it now shows the toggle with the same appearance as the IupButton element, but maintaining its functionality the button remains pressed until the user clicks it again. The IMPRESS attribute can be used to define the image used for the pressed button. In this case, the user is in charge of giving it a 3D appearance.
  • IMPORTANT: The size of the dialog can be adjusted after being mapped, by means of the SIZE and RASTERSIZE attributes
    • The size of the dialog has now precedence over the smallest size required by its children (either having been specified in its creation or in run-time).
    • Attributing a NULL value to the SIZE or RASTERSIZE (in C) of a dialog will re-compute its size according to the size of its children.
    • Partial dimensions (###x and x###) are now treated correctly.
    • Therefore, applications that define sizes for dialogs (either in LED or in C) smaller than the minimum size required by their children will show truncated dialogs. To force a computation based on the size of the children, set any of these attributes to NULL (in C) or simply do not define them in LED. As a general rule, avoid specifying a dialog size unless there is a real need for such in this case, be careful to specify a sufficient size.
  • IupFileDlg:
    • The default value for the DIALOGTYPE attribute was not being recognized (the program aborted when there was no defined value).
    • When ALLOWNEW = NO, the dialog informs if the user is specifying a non-existing file (instead of simply returning, as was happening).
    • When the dialog type was OPEN, the returned value was 1 (Cancel) even when the user confirmed the operation.
    • If DIALOGTYPE is SAVE, a confirmation is required if the file already exists.
    • A new dialog was created for each popup without destroying the previous dialog.
    • The NOCHANGEDIR attribute was implemented.
    • The dialog does not return if the user specifies a new file when attribute ALLOWNEW = NO. The same happens when attribute ALLOWDIR = NO and a directory is specified. In these cases, alerts are shown.
  • The iupGetColor function for CPI controls was replaced in functionality by the iupGetRGB function (iupGetColor is maintained for compatibility purposes, but it should no longer be used).
  • TRUECOLORCANVAS was created. It indicates if the display allows the creation of TrueColor windows (> 8bpp), even if the default is PseudoColor.
  • Tabs: a problem was fixed concerning the use of the VISIBLE attribute for elements belonging to a non-selected tab.
  • IupHelp: allows using a browser (default = Netscape) for viewing HTML pages.
  • The ACTION_CB callback, from IupText, now receives, apart from Ihandle* and int, a char* pointing to the new text value in case the key is confirmed.
  • Dropdown lists were not correctly processing the VISIBLE attribute.
  • A problem with the initialization of multiple-selection lists was solved: the VALUE attribute was not being respected in some cases.
  • Attributes FGCOLOR and BGCOLOR from the dropdown list were not being correctly updated.
  • IupLoopStep was re-implemented: now it no longer blocks when there are no events to be processed (it simply returns DEFAULT).
  • The dropdown list is closed when the associated textbox is totally or partially darkened.
  • The dropdown list was not being closed when the dialog lost the focus if IupIdle was registered.
  • A problem in the exhibition of CPI controls was fixed.
  • New return code (CONTINUE) was created, specific for key callbacks, to be used when the event is to be propagated to the parent of the element receiving it.
  • In some situations, elements destroyed by means of IupDestroy were receiving events, making the application abort.
  • The redefinition of items in the main menu was making the dialog return to its original size.
  • Consulting attribute BGCOLOR in a dropdown list was aborting the application.
  • Consulting attributes BGCOLOR and FGCOLOR of a canvas with a different visual from the default was generating an X-Windows error message.
  • The problem with IupFileDlg was fixed (the application was aborting).
  • IupDestroy in a bar menu was inducting an infinite loop to the application.
  • The list now matches the documentation: it calls the action callback for the de-selected element (with the v = 0 parameter).
  • Bug correction: The use of a Motif attribute instead of a function was making Motif lost control of memory management (memory already liberated was liberated again, which aborted the application).
  • ACTION in IupText caused SIGSEV when the user pressed ENTER.
  • New IupMapFont for mapping IUP fonts -> Motif.

Version 1.8.2
