History of Changes

Version 2.3 (16/Mar/2005)

General

  • Download, Discussion List, Submission of Bugs, Support Requests and Feature Requests, are now available thanks to LuaForge site.

  • New organization of the documentation.

  • New MacOS X libraries using OpenMotif and gcc.

  • New CARET_CB callback for the IupText, IupMultiline and IupList controls. It is called every time the caret changes its position.

Windows

  • IMPORTANT: Now the canvas background color is only redrawn if the ACTION callback is not defined. When defined the application must draw all the canvas contents. This will optimize the redraw of canvas based controls and application canvases. The TRANSPARENT value for the BGCOLOR is not supported anymore.
  • New attribute IMMARGIN to control the spacing between the border and the image in IupButton.
  • Optimized the IupButton and IupLabel drawing when IMAGE is specified.
  • Fixed incorrect stop for the IupTimer. Improved start and stop control.
  • Flicker now is significantly reduced. CLIPCHILDREN=YES is now default. IupFrame background drawing optimized.
  • New dialog attribute "CONTROL" that enable the embedding of the dialog inside another window. Used by LuaCOM to create OLE (ActiveX) controls implemented in Lua.
  • New IupText attribute "PASSWORD" to hide the typed character.
  • IUP is now compatible with Windows XP Visual Styles. See the Win32 driver documentation.

Motif

  • Fixed invalid return value when retreiving the FONT attribute.

  • Added backward compatibility code for Motif 1.2. Must edit makefile to add the file "src/mot/ComboBox1.c".

IupControls

  • Missing support for IupList with EDITBOX=YES in iupMask.

  • BGCOLOR for images were ignored in the IupTree.

  • Now some matrix cell attributes are not inherited from parent. Like "L:C", "ALIGNMENT*", "FGCOLOR*", "BGCOLOR*", "FONT*", "WIDTH*" and "HEIGHT*", for optimization reasons.

  • IupTree now uses double buffer for optimal drawing.
    To avoid flicker during resize in Windows, do not use it inside a IupFrame, and use CLIPCHILDREN=YES.

  • New utility functions: IupTreeSetAttribute, IupTreeStoreAttribute IupTreeGetFloat, IupTreeSetfAttribute, IupTreeGetAttribute, IupTreeGetInt.

  • New IupMatrix callback DRAW_CB to allow a custom drawing of the cell contents.

  • New IupTree DRAGDROP_CB callback.

  • New IupSpin and IupSpinbox utility functions.

IupLua

  • Fixed ihandle_gettable in iuplua.lua when iupGetTable is nil when object is created in C.
    This affected the object returned by iup.LoadImage.
  • Fixed Zbox children names initialization.
  • Missing DROPFILES_CB callback management.
  • Missing FGCOLOR_CB and BGCOLOR_CB callback management for the IupMatrix. The returned values order was inverted.
  • Missing MAP_CB callback management for IupCanvas in IupLua3.

  • Fixed IupGetParam invalid memory access.

  • IupNextField and IupPreviousField now only changes the focus for the checked toggle inside a radio.

  • IupGetAttributes now returns the pointer address if attribute is a known internal pointer data.

  • Now pressing Enter over a button activates it, even if it is not the DEFAULTENTER button.

  • Esc and Backspace keys now will be translated even if CapsLock is active.

Windows

  • New ENTERWINDOW_CB and LEAVEWINDOW_CB for buttons.

  • Fixed double click for button, toggle and list were not being considered as two clicks.

  • removed FLAT style from toggles with IMPRESS image. Fixed size of toggle with image.

  • New attribute SHOWDROPDOWN to open the dropdown list programmatically.

  • Removed a black border around IupMultiline and IupText.

  • Removed the TABSTOP for non marked Toggles inside a Radio.

  • Fixed invalid memory access when menu item is activated and all dialog controls are disabled.

  • Fixed IupFileDlg ignored the x,y parameters of IupPopup.

Motif

  • Enter in IupMultiline activated the DEFAULTENTER button instead of adding a new line.

  • Fixed invalid memory access when set FONT to NULL.

  • Fixed ACTION callback called for IupList when list contents were cleared.

IupControls

  • IupTree and IupTabs did not propagate to the parent the K_ANY callback for non used keys.

IupMatrix

  • The TITLEs, BGCOLORs, FGCOLORs and FONTs attributes were incorrectly set after a DELLIN, ADDLIN, DELCOL or ADDCOL.

  • In Windows when the user double click a dropdown list now will start opened.

  • Fixed when MARKMODE=LIN/COL/LINCOL if the first cell in the line/column is selected the click in the title area was ignored.

IupLua

  • Removed "print" debug calls in internal code.

  • IupGetAttribute/iup.GetAttribute now returns an user data if attribute is a known internal pointer data.

  • New IupGetAttributeData/iup.GetAttributeData that returns the data always as an used data.

  • The button callback now is called only when the button is released inside the button area.

  • WOM callback renamed to WOM_CB.

  • New "HELPBUTTON" attribute for the dialog.

  • The menu item now accepts auxiliary bitmaps.

Controls

  • DEFAULTESC and DEFAULTENTER were missing in IupGetColor.

  • New function IupLoadImage that uses the library IM to load an image file (implemented in an additional library).

  • New dialog IupGetParam, similar to IupScanf but uses variable controls for fields.

  • IupTabs now uses the FGCOLOR for the text color.

  • ICTL_DASHED was missing in the documentation of IupGauge.

  • Fixed some display erros in Windows because of an error in the size of the scrollbar.

  • In Windows pressing a key in a menu activates the k_any of the last active element. In the matrix this turns into an infinit loop. The matrix now uses the keypress_cb instead of the k_any callback.

  • 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.

  • After editing the cell in the last line, now the focus goes to the column on the right at the last line, instead of the first line.

General

  • Attribute IUP_TYPENAME replaced by IupGetType function
  • minor bugs introduced in 2.0 because of internal old misuse of the hash table. 
  • Following controls were not working with LED: val, dial, gl, matrix, tree.
  • New canvas attribute "DRAWSIZE" that returns the drawing area of the canvas (in Windows we may have an addicional border included in "RASTERSIZE").

Windows

  • Memory invasion when eliminating an item from an IupList with multiple items.
  • Callback IUP_OPEN_CB sometimes was not being called.
  • New dialog attribute "BRINGFRONT" which forces dialog to be the window in the front. Useful for multithreaded applications.
  • Attribute ACTIVE was not working with radio control.
  • Now folder selection in IupFileDlg uses IUP_DIRECTORY as a start path.
  • Now when ESC or ENTER is pressed KEYPRESS_CB is generated
     

Motif

  • Dropdown were not being positioned accordingly.
  • IupList was not selecting the first item.
  • IupTimer callback were called only once.
  • The value "BGCOLOR" in a value of an image color table index appeared with erroneous color.
  • keyboard and mouse callbacks were not being called when in full screen.

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).
