wmaker/WINGs/ChangeLog

changes since wmaker 0.61.1:

- added WMSaveUserDefaults().
- rewrote WMPopUpButton to use WMMenuItem
- added WMGetPopUpButtonMenuItem(WMPopUpButton *bPtr, int index)
- WMSortListItemsWithComparer(WMList *lPtr, (int)(f)(const void*, const void*))
- fixed bug with sorting list items.
- fixed bug in handling keyboard input associated with selection and
  notification sending.


changes since wmaker 0.61.0:
............................

- added WMGetTextFieldFont()
- escape key in panels (craig nellist <crn@ozemail.com.au>)
- applied patch with fixes and enhancements to textfield 
	(Franck Wolff <wolff@cybercable.fr>)

- replaced WMAddSortedListItem() with WMSortListItems()

changes since wmaker 0.60.0:
............................

- added WMScreenWidth() and WMScreenHeight() functions.
- fixed some problems when compiling with non gcc compilers.
- added WMSetTextFieldFont()
- added WMSetButtonImageDefault() (craig nellist <crn@ozemail.com.au>)
- added WMBag (array/list)
- added libWUtil, a library that is a subset of libWINGs. It contains utils
  that can be used in writing non-GUI programs. They include: hashes,
  notifications, input/idle/timer handlers, user defaults database handling,
  memory handling, application resource handling, etc.
  All the non-GUI stuff from libWINGs is present.
  Still linWINGs contain all this stuff so if you use libWINGs, you don't
  need to link against libWUtil too.
  One notable aspect of libWUtil is that it has a modified version of the
  event handling function. It is named WHandleEvents() and will handle all
  input/idle/timer events the app has.
  If your app has a permanent input handler (as for example a socket a server
  is listening on), then the main loop of the app can be:
  	while(1) {
    	    WHandleEvents();
  	}
  but if there is no permanent input handler, you need to add some delay to
  avoid a too high cpu load by your program:
  	while(1) {
            WHandleEvents();
            wusleep(5000);
        }
  A permanent input handler is one that is established when the program starts
  and is present until the program exits.
  One that is deleted and later reinstalled, is not considered permanent.
  This difference is because if there is some input handler, the function will
  block until some event appears, while if there is no input handler the
  function will return almost immediately (after handling the timer/idle
  stuff).

  Except the stuff declared in WUtil.h, the following functions declared in
  WINGs.h are also present in libWUtil (you will need to #include <WINGs.h>
  if you use one of these):
	WMInitializeApplication(char *applicationName, int *argc, char **argv);
	WMSetResourcePath(char *path);
	WMGetApplicationName();
	WMPathForResourceOfType(char *resource, char *ext);
	WMAddTimerHandler(int milliseconds, WMCallback *callback, void *cdata);
	WMDeleteTimerWithClientData(void *cdata);
	WMDeleteTimerHandler(WMHandlerID handlerID);
	WMAddIdleHandler(WMCallback *callback, void *cdata);
	WMDeleteIdleHandler(WMHandlerID handlerID);
	WMAddInputHandler(int fd, int condition, WMInputProc *proc,
        		  void *clientData);
	WMDeleteInputHandler(WMHandlerID handlerID);
- added progress indicator widget
- Changed WMSetWindowUPosition() and WMSetWindowUSize() to
  WMSetWindowInitialPosition() and WMSetWindowInitialSize() respectively,
  for better naming conventions.


changes since wmaker 0.53.0:
............................

- added balloon help
- fixed a bug with setting initial path in browsers.
- added WMSetButtonImageDimsWhenDisabled()
- changed simple callback/notifications to delegate-like stuff. Affected
  widgets are:
  	WMBrowser
	- WMSetBrowserFillProc() was replaced with WMSetBrowserDelegate
	- WMBrowserDidScrollNotification was replaced with a delegate callback

	WMTextField (not completed yet)
	The notifications will still work, but using the delegate is preferable

  How to convert old code to delegate callbacks:
  	1 - create a variable (static or dynamic) of the type of the 
	    delegate for the widget type.
	2 - Replace the notification observers with the equivalent 
	    delegate callbacks. 
	3 - Put pointers to the callbacks in the delegate variable.

	Take a look in wfilepanel.c to see how it is used there.

- changed W_ViewProcedureTable to delegates
	This will only affect user created widgets. If you have a custom
	widget, you will need to update the callbacks and the declaration
	of the W_ViewProcedureTable variable to be a W_ViewDelegate,
	which is declared in WINGsP.h  To setup the delegate, assign
	the delegate variable to view->delegate.

- WMTextField
	Removed all the didChange notifications that were sent when the text
	was changed programmatically. Only changes made by user interaction
	will be notified now. If you need the old behaviour, send notifications
	manually when you change the text.

- added WMTabView
- added WMGetColorPanelColor(WMColorPanel *panel)
- made WMGetUDStringForKey() to only return a reference to the string, not a
  wstrdup()'ed copy. DO NOT FREE IT ANYMORE!
- added MultiByteText option to userdefaults file to control use of multibyte
  string drawing functions
- renamed WMCreateFont() to WMCreateFontSet()
- renamed WMCreateFontInDefaultEncoding() to WMCreateNormalFont()
- added WMCreateFont() with different semantics
