• Fixed empty selection in the dropdown list if the user press a regular key to start editing the cell.

• Fixed invalid dropdown value if the user changed focus to the scrollbars.

• CLICK_CB was called twice in a double click (press+release).

• In Motif, the textbox and the dropdown did not open when you double click a cell. But now the user still needs to click again in the control to put it into focus.

LEDC

• Updated to reflect 2.0 changes like "iupmatrx" to "iupmatrix".
• Now tests if name is not NULL before using IupSetHandle.

IupLua

• New binding for Lua 5. This is beta version since uses old notation "iuplabel" instead of "iup.label".

Version 2.0 (23/Jun/2003)

General

• IUP has undergone a large internal reorganization, but no structural or algorithmic changes have occurred. The purpose of this reorganization was to standardize function, variable and module nomenclature. This process is not yet complete, but the few remaining details will be solved in the next version.
• Table Hash was completely replaced with a modified version of Lua 4. This version is internal of IUP and does not affect applications. This has brought us a better management of the memory used by attributes.
• The CPI was changed to allow the creation of native controls, as well as controls based on IupCanvas. The internal controls were not yet rewritten over the new CPI - this will be done progressively in the next versions.
• The Ihandle definition changed from "void" to "typedef struct Ihandle_ Ihandle;". This has direct implications on C++ applications that did not do pointer typecast. In C++, code errors might occur and, in C, there might be warnings.
• New control IupTimer. Allows creating timers in Windows and Motif.
• New callback "KEYPRESS_CB". Allows intercepting any key and replacing all callbacks "K_xxx".
• IupHelp was rewritten in a simpler way. In Windows, it simply uses the system's configuration to open a URL and, in UNIX, it directly runs Netscape or another executable configured by an environment variable.
• New attribute "FULLSCREEN", allows creating a dialog that occupies exactly the whole screen.
• Dialog IupGetFile was rewritten using IupFileDlg.

Windows

• New attribute "CURSORPOS", allows programmatically changing the cursor's position on the screen.
• New attribute "NOOVERWRITEPROMPT" for IupFileDlg. It prevents IupFileDlg in Save mode from asking the user if s/he really wishes to overwrite a file.
• Problem corrected in the file list in the use of attribute "MULTIPLE_FILES" for IupFileDlg. When only a folder was selected, it was not setting the "STATUS" attribute in a cancelled action.
• Greater driver stability - Ihandle is no longer dependant on the native handle (HWND).
• New global attributes "HINSTANCE", "SYSTEMLANGUAGE", "COMPUTERNAME", "USERNAME".
• Global attribute IUP_SYSTEM now returns a more complete string.
• Cursor now changes instantly - it only changed before returning to IUP.
• In an inactive IupToggle, the IMINACTIVE image is now correct.

Motif

• The iupmot library no longer exists. Tecmake has been updated, but those who use their own metafiles must remove this file from the list of libraries in the application.
• New attribute "AUTOREPEAT" allows turning on and off the automatic repetition mode of pressed keys.

IupLua

• [4/5] IupListDialog when selection type is 1 (single) was not returning any value.
• [4/5] Callbacks mapcb and showcb had their names wrong: map_cb and show_cb
• [3] Callback action in IupMultiline was not passing the parameter "after".
• [4/5] In IupTree, callbacks "afterselection" and "beforeselection" were replaced with the callback "selection".

IupControls

• We have joined seven libraries in one: dial, gauge, cb, gc, mask, tabs and val. But neither the initialization functions nor each control's inclusion files were changed. The source code does not need to be altered, except for the makefiles. Tecmake was given a flag USE_IUPCONTROLS to automatically include this library.

IupMatrix

• The name of the library was changed from "iupmatrx" to "iupmatrix". The same for the inclusion files. Therefore, all applications that use IupMatrix must change the source code and the makefile to reflect these changes.

IupTree

• In one case, the active CD canvas was not being returned to the old canvas before drawing.

IupGL

• In Linux, the additional GLw library was added to the control library.
• New attributes for query in UNIX: CONTEXT (GLXContext), VISUAL (XVisualInfo*) , COLORMAP (Colormap).

• 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 Driver 

• 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 driver’s 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 Driver 

• 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 Driver 

• 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 Toggle’s 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 

• DROPDOWN’s 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 user’s 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 IupText’s 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_ENGLISH’s 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 dialog’s 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 library’s opening message now follows a standard.
• IupLua was passing Lua’s 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 IUP’s Help, run W:\iup\help\iuphelp.reg (ATTENTION: On Visual Studio, IUP’s 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 Driver 

• 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 driver, 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 dialog’s IupPopup was not functioning.

Motif Driver 

• Several memory leaks were fixed. They occurred when IupGetAttribute called functions from XM which allocated memory to store the attribute’s 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 driver 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 Driver 

• Function iupdrvSetIdleFunction was added to make the Windows driver 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 item’s callback was fixed.

Motif Driver 

• 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 Driver 

• 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 Driver 

• 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 Driver 

• 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 “parent’s”. 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

Windows Driver (12 Jan 99)

• Function char* IupMapFont( char* font ) converts a IUP font describer (used by the IUP_FONT attribute) into a native font describer (used by IUP_WIN_FONT).
• File Drag & Drop was implemented in dialogs and canvases, via the IUP_DROPFILES_CB callback.
• Attribute IUP_EXTFILTER was implemented for the IupFileDlg control, allowing the use of more than one filter.
• Changes were made to allow the creation of CPI elements other than CANVASes or dialogs.
• The IUP_ACTIVE attribute of a dialog can now be changed after it was mapped.
• List callback correction: the callback is now called both for selected and not selected items.
• New function void IupHelp(char *url) shows a URL in a Netscape window.
• The treatment of the new return value for keyboard callbacks, IUP_CONTINUE, was implemented.
• IUP_CURSOR attribute was implemented.
• A code was added to treat the case of toggle de-selection via IupSetAttribute.
• IUP_CARET now uses ‘,’ as a separator instead of old ‘:’.
• A restriction was eliminated that prevented the function iupGetTextSize from being called passing a dialog or frame as a parameter.
• New text callback was implemented; it receives the text both before and after the change, and receives the code of the typed key.
• It was possible to set two activated radio toggles by selecting VALUE for one of them on the radio and VALUE = ON on the other toggle.
• Attributes IUP_STARTFOCUS, IUP_DEFAULTENTER and IUP_DEFAULTESC were implemented.
• The IUP_VALUE of a IupRadio was not allowing to be changed if it was not visible.
• A problem was corrected for the lists, which were being reset between a IupShow/IupPopup and another.
• Attribute IUP_SELECTEDTEXT was implemented. It returns the selected text (if there is any), with the ‘\r’ already filtered.
• A bug was corrected; it caused and “Assertion Failed” when the mouse was moved after a window was destroyed.
• The value of IUP_VALUE of a IupText and a IupMultiline now does not contain ‘\r’.

Motif Driver v1.8.2 (14 Aug 98)

• IupFileDlg was corrected: the IUP_FILE and IUP_DIR attributes were not being treated correctly.
• In some specific situations, closing a dialog could lead to the end of IupMainLoop, causing an abortion of the application.

Motif Driver v1.8.1 (16 Jun 98)

• Correction: IUP’s Matrix element was being shown with different fonts from the ones used by IUP, especially on UNIX platforms.
• Dropdown list (combo box) remained opened if the element was hidden or destroyed.
• The use of popup dialogs was sometimes preventing the last IUP_CLOSE (or IUP_DEFAULT) from ending IupMainLoop.
• [LINUX] The button press event was not being received by the canvas when the CTRL key was pressed.
