## History of Changes in Version 2.x

### CVS (17/Jun/2009)

#### General

- Changed: the IupOleControl in Lua will not automatically initialize LuaCOM anymore. The application must manually call "elem:CreateLuaCOM()". The previous initialization was incorrect (thanks to Ross Berteig).
- Fixed: parameter checking and the return value in Lua for IupListDialog when type=2.
- Fixed: the return value for IupGetText when the user canceled.
- Fixed: The 32 bits version of the IupLua console in Windows XP64 was not working.
- Fixed: IupLua initialization when retrieving the argc/argv arguments for IupOpen. (Thanks to Ross Berteig)
- Fixed: action callback return value in Lua for the IupGetParam dialog. (Thanks to Zhiwei)

### Version 2.7.1 (15/Dec/2008)

#### General

- Fixed: the iuplua51 makefile where not using the g++ linker, so require"imlua" failed.
- Changed: removed csh dependency from make_uname scripts.
- Changed: removed IupSpeech from source and documentation.

#### Motif

- Fixed: IupOpen was crashing if used with NULL parameters.

### Version 2.6 RC2 (10/May/2007)

#### General

- New: function IupUpdate to force a redraw of the element and its children.
- New: function IupExitLoop to exit the current message loop. It is equivalent of returning IUP_CLOSE in a callback.
- Changed: now for the IupList when DROPDOWN=Yes the size of the dropped list will expand to include the largest text.

### Version 2.6 RC1 (15/Apr/2007)

#### General

- New: functions IupGetChild, IupGetAllAttributes.
- New: CLIPBOARD attribute with COPY, PASTE and CUT values for IupText and IupMultiline.
- New: control IupPPlot that uses the PPlot library to draw 2D plots. Thanks to Marian Trifon.
- Changed: LEDC now supports IupCells, IupCbox, IupOleControl and IupSpin.
- Changed: IupMultiline and IupText size calculation. When EXPAND is different than NO or NULL, the control will ignore its contents when calculating the control size if SIZE or RASTERSIZE is not set. So now if text is larger than the multiline and EXPAND is set, the multiline will not expand to include its contents when the dialog is expanded. In this case the multiline will be expanded only what the dialog allows it to expand.
- Changed: size update when FONT is set. Now to update the control size IupRefresh must be called.
- Fixed: Added missing documentation of IupGetParent.
- Fixed: caps lock key codes.
- Fixed: Added missing IupSetAttributeHandle and IupGetAttributeHandle exports in the DLL.

#### Windows

- Fixed: WHEEL_CB parameters x and y.
- Fixed: IupPopup for menus when used in the Tray if there is no visible dialogs.
- Fixed: FONT attribute initialization when control is not mapped yet. Affected mainly controls inside other controls.
- Fixed: FONT attribute parse when value is invalid.

#### Motif

- New: TOPLEVEL global attribute.
- Changed: default IupHelp application in Linux to "firefox".
- Changed: some attributes were updating the size of the control in the dialog. Now to update the control size IupRefresh must be called.
- Fixed: Idle processing.
- Fixed: return value of IupLoopStep.
- Fixed: invalid resize of IupList when COMBOBOX=YES and an element is added dynamically.

#### IupLua

- New: convertion to string for an Ihandle. Now returns "IUP(type): address", for example "IUP(dialog): 08C55240".
- Changed: IupLua5 executable in Windows to enable GDI+ in CD library.
- Changed: IupLua3 libraries names changed to include "3" as a suffix.
- Fixed: Added missing IupGLIsCurrent binding.
- Fixed: error message management when inside a callback in Lua 5.
- Fixed: error handling in iuplua_dofile and iuplua_dostring.
- Fixed: the second ihandle parameter inside the callabacks in Lua 3: DROP_CB, DROPSELECT_CB and TABCHANGE_CB.
- Fixed: conflict in dialog resize attribute with resize callback from canvas in Lua 3.
- Fixed: getattribute metamethod when value is not a number or string before calling GetHandle to check if it is a handle.
- Fixed: setattribute metamethod when value is stored in C now is also set to nil in Lua to avoid old invalid values in Lua.
- Fixed: IupAlarm optional parameters in Lua 3.
- Fixed: missing edit_cb callback definition for IupList in Lua 5.

- Fixed: BGCOLOR and FGCOLOR for full lines or full columns in titles (L:* or *:C).
- Fixed: BGCOLOR for titles and empty area to use the parent's BGCOLOR instead of the dialog BGCOLOR.
- Fixed: BGCOLOR_CB and FGCOLOR_CB in Lua when IUP_IGNORE is returned.
- Fixed: setting VALUE attribute when the cell is being edited.
- Fixed: redraw when resizing collum and the scroolbar is added to the canvas in Windows.
- Fixed: redraw in SunOS after editing the cell.

#### Other IupControls

- Changed: in IupTabs, when next or previous tab is selected using the arrow buttons or arrow keys, inactive tabs are skipped.
- Changed: CD calls to use the new CD API available only in CD version 5.0. So IUP will not be compatible with old CD versions.
- Changed: Because of the new parameter of DRAW_CB callback in IupMatrix, the IupControls Lua binding now depends on the CD Lua binding.
- Fixed: F2 key processing to rename a node in IupTree.
- Fixed: focus change when changing the active tab in IupTabs.
- Fixed: BUTTON_PRESS_CB and BUTTON_RELEASE_CB binding in Lua 3 for IupDial and IupVal.
- Fixed: IupTree rename box position when using scrollbars.

#### IupGLCanvas

- New: SHAREDCONTEXT attribute.
- Fixed: Added missing DLL export IupGLIsCurrent.

### Version 2.5 (31/Mar/2006)

#### General

- IMPORTANT: New functions IupSetCallback and IupGetCallback to register callbacks without using a global name. IupGetFunction and IupSetFunction are still working, but are not used internally anymore. The new functions speed up the performance of callbacks, and reduce to zero name conflicts for callbacks in the global name table. It is recommended that the applications should replace IupSetFunction and IupGetFunction by IupSetCallback and IupGetCallback. IupLua applications are automatically benefited.
- IMPORTANT: Applications that overload internal callbacks of the additional controls (like IupMatrix and IupTree) must now use IupSetCallback and IupGetCallback to do the overloading. And as before these callback can not be overloaded in Lua.
- IMPORTANT: removed the support for callback inheritance. Now callbacks can only be set in the own element. The only execption is the K_ANY and the K_* callbacks that continues to be propagated to the parent of the element with the keyboard focus. (This was a not very usefull feature, with very few uses. But slows a lot calback management in C and in Lua. With the new IupGetCallback we were able to remove the inheritance mecanism for callbacks.)
- Changed some function declarations of the main API, some now use "const char*" in their declaration.
- Changed global attributes now are stored only if not processed by the driver.
- IMPORTANT: Changed the definition of Icallback to a simple one without the variable arguments. Fixed canvas callback parameters, in the documentation is float, but with the old Icallback definition the compiler used double. Now must be float.
- Changed all the internal attributes now start with the preffix "_IUP".
- Changed the default limit for text in IupText and IupMultiline to be 231.
- New canvas callback FOCUS_CB.
- New helper function IupSetAttributeHandle to associate Ihandle* to attributes using automatic names. Instead of using IupSetHandle and IupSetAttribute with a new creative name, this function automatically creates a non conflict name and associates the name with the attribute. Also new function IupGetAttributeHandle.
- New "Pause" button in the IUP Image Library.
- Fixed the MULTISELECT_CB callback of the IupList so it does not need that the ACTION callback is also defined.
- Reviewed the popup dialog management. So we improve the behavior of the IupShow of other dialogs after a IupPopup, and a new possibility to safely cascade popups.

#### Windows

- IMPORTANT: Global attribute WIN_DEFAULTFONT renamed to DEFAULTFONT.
- Fixed attribute PLACEMENT=NORMAL when the dialog in minimized or maximized.
- Fixed IupPopup for menus, when the menu item callback returned IUP_CLOSE, the return value is now processed and the application is closed.
- Change WOM_CB and be set also for the dialog.
- Changed CoInitialize to CoInitializeEx[COINIT_APARTMENTTHREADED] and InitCommonControls to InitCommonControlsEx[ICC_WIN95_CLASSES] in IupOpen.

#### IupControls

- Changed the GETFOCUS_CB and KILLFOCUS_CB callbacks for the additional controls IupMatrix, IupVal and IupDial, now can be set without affecting their implementation.
- Changed the K_ANY for the additional controls IupTree, IupSpin and IupColorBrowser, now can be set without affecting their implementation.
- New DOUBLEBUFFER attribute for IupTabs. Default is YES. If NO will disable the double buffer. This may solve a slow Tabs redraw in UNIX when the a Tab contains many controls.
- New IupVal attributes HANDLER_IMAGE and HANDLER_IMAGE_INACTIVE that allow the use of images to replace the handler. Thanks to Rodrigo Espinha.
- Reviewed and optimized iupMask code. Added new callback MATCH_CB.

#### IupMatrix

- IMPORTANT: Callbacks ACTION and SCROLL_CB were renamed to ACTION_CB and SCROLLTOP_CB to avoid conflict with the IupCanvas callbacks also inherited by the IupMatrix.
- IMPORTANT: You can not automatically override the KEYPRESS_CB callback anymore. You must save the original callback and call it from inside your own.
- IMPORTANT: Now when in callback mode much less memory will be allocated. Also the new callbacks MARK_CB and MARKEDIT_CB can be used to control the selected cells in callback mode.
- Fixed some string buffer sizes to handle very large matrices.
- Fixed IupGetAttribute for the VALUE attribute when using callback mode and retrieving colum or line title values ("0:C" or "L:0").
- Changed "matrx_img_cur_excel" to "IupMatrixCrossCursor". Old name is still available.

#### IupTree

- IMPORTANT: The IupTree implementation now uses the KEYPRESS_CB callback. The K_ANY override support was removed. The K_ANY callback can be used normally. If the application was using the KEYPRESS_CB, now it must override it manually, you must save the original callback and call it from inside your own.
- Change the appearance in Windows and Motif are now the same. Both systems look like the previous Windows implementation with a white background and some small enhancements.

#### IupLua

- IMPORTANT: IupLua3 now supports IupLua5 names. Old IupLua3 names still work, but now all the samples for IupLua5 also work in IupLua3. The documentation and the examples for the old names were removed from the manual pages. Old applications using IupLua3 can use the old names or the new names. This will make easier to old applications migrate their code to Lua 5. All Lua examples were re-tested and fixed.
- IMPORTANT: In IupLua3 the callbacks in C are registered only when the application register the callback in Lua, just like in IupLua5.
- IMPORTANT: IupColorBrowser name changed in IupLua3 from "iupcb" to "iupcolorbrowser".
- Fixed documentation of IupGetAllDialogs and IupGetAllNames. Fixed implementation to match the documentation.
- Fixed IupTimer old callback name in IupLua3.
- Fixed DROPFILES_CB canvas callback can be now used in Lua for the controls based in IupCanvas, like IupMatrix and IupTree.
- Fixed parameters of the canvas action and scroll_cb callbacks in Lua 5.
- Fixed missing FILE_CB callback in Lua.
- Changed all the additional controls now can have the K_ANY, GETFOCUS_CB and KILLFOCUS_CB callbacks without affecting their internal implementation.
- Changed Lua 5.1 "require" can now be used for all the IupLua 5.1 libraries, but the full library name must be used. For example: require"iuplua51", require"iupluacontrols51".
- Documented the IupLua 5 architecture.
- Reviewed and reorganized IupLua3 and IupLua5 code, also cleaned and simplified. In IupLua3 callbacks are now set only if they are set by the application.
- Changed IupClose can now be called from Lua in Lua 5.
- Reviewed and improved the interchange of Ihandle between C and Lua. The documentation was updated with all the possibilities.

### Version 2.4 (12/Dec/2005)

#### General

- New attribute ZORDER to change the zorder of any control or dialog.
- New 3STATE attribute for IupToggle to enable a three state text toggle.
- Reviewed and improved the creation of controls, so they can be added to an already created dialog.
- Reviewed and improved the natural size estimation for each standard controls. The estimation now is the same for Windows and Motif with some minor differences for border and scrollbar sizes. All the controls can have sizes bigger or smaller than the natural size using SIZE or RASTERSIZE attributes (natural size is the size of the control that fits all of its contents).
- Improved FULLSCREEN IupDialog attribute in Windows and Motif, so the application can set fullscreen and then restore to normal state any time.
- New attribute FLAT for IupButton to create a button with mouse over activation (Windows and Motif).
- New MULTISELECT_CB callback for IupList. It can replace the action callback for multiple selection lists.
- Fixed names of headers, initialization functions and libraries that did not have the "iup" prefix. Headers "iupolecontrol.h", "luacontrols.h" and "luagl.h" changed to "iupole.h", "iupluacontrols.h" and "iupluagl.h". Private headers and declarations removed from "iup/include" folder. Functions controlslua_open, gllua_open and iupluaim_open changed to iupcontrolslua_open, iupgllua_open and iupimlua_open.
- New documentation of the IupOleControl control, including a sample and Lua bindings. Thanks to Vinicius Almendra.

- Optimization flags now are ON when building the library in all platforms.
- Now all the predefined dialogs consult the global attribute IUP_ICON.
- Missing key definitions: K_sDEL and K_sINS. This prevented the Del key to work when CAPSLOCK was active in some controls.

- Fixed image offset in IupButton.
- Fixed invalid redraw for IupLabel using an IupImage when inside a IupTabs or IupSbox.
- Added an "ifndef IUP_NO_ABNT" enclosing the ABNT keyboard management so it will be easier to ignore this code from the makefile.
- Default FONT in Windows XP is now the Tahoma font.
- BGCOLOR for canvas was not being updated correctly when changed after canvas creation.

#### Motif

- SHOWDROPDOWN now works also in Motif.
- Removed horizontal scrollbar parameter from simple IupList (DROPDOWN=NO and EDITBOX=NO) to made it compatible with the other lists (including the simple IupList in Windows).
- Fixed KILLFOCUS_CB and GETFOCUS_CB for IupList with DROPDOWN=YES or EDITBOX=YES.
- Fixed invalid IupList resize when DROPDOW=Yes after inserting elements in the list.
- New BACKINGSTORE IupCanvas attribute so the backing store can be disabled.
- Changed IupToggle with IMAGE and IMPRESS to behave like in Windows, where the button border is always shown.
- Fixed error in menu item initialization.

#### IupControls

- IMPORTANT: for best results CD version 4.4 should be used.
- Fixed IupSpin keyboard response and mouse press & hold response.

#### IupMatrix

- Redefined REDRAW policy to a more precise and effective one. No redraw is done when the application sets cell, line or column graphics attributes attributes: 0:0, 0:C, L:0, L:C, ALIGNMENTn, BGCOLORL:*, BGCOLOR*:C, BGCOLORL:C, FGCOLORL:*, FGCOLOR*:C, FGCOLORL:C, FONTL:*, FONT*:C, FONTL:C. Global and size attributes always automatically redraw the matrix.
- Improved double click editing in Motif. Since OpenMotif 2.2.3 the double click to edit the cell works fine. For previous version there is still a workaround to show the controls and the need to click again in the control so it get the focus.
- All the edition mode code were rewritten and reorganized in a separated module. Any old code was removed and cleaned.
- Small change in focus feedback, its area was reduced to two pixels in each cell border.

- Changed IupText and IupMultiline now can have the ALIGNMENT attribute.

#### Motif

- Fixed use of variable parameter arguments in Motif calls to correct 64-bits compatibility.
- Fixed some small bugs in IupDestroy. GETFOCUS_CB callbacks were called during dialog destroy. Menu bars were incorrectly destroyed.

#### IupControls

- 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.

- 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.

- 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).
