Still a long + ways to go... +6/8/97: Added fl->add_xevent_handler so your program can get at those + XExtension events. Rewrote fl->selection_owner so it uses + this, mostly to test it. Added Fl_Implementation.H header + to src to clean up public header files. +6/5/97: Added Fl_Window::show(argc,argv,i) so that standard switches + can be passed to the main window in a window-system + independent way.

The only way to stop + the close box from closing a window is to subclass it and + change the response to FL_CLOSE. The callback is done, + however, before closing the window. Added exit() and error() + methods to Fl class, which you can "override" by defining + your own versions in your source code. +1/24/97: Restored setting of XSizeHints (many window managers ignore + the Motif window information). + +FL-0.93 + +1/23/97: Got it to compile and run (with -DNO_GL) on Dec Alpha Unix! + Mostly this meant getting rid of trailing commas on enum lists. +1/20/97: DDForms-compatable resize behavior, where it scales + everything inside the resizebox.

This + bug caused Mesa 2.0 to crash. Fixing it required extensive + rewriting of the Fl_Window base classes and virtual functions. +10/../96: Lots of work done on writing fluid +10/09/96: Added the Fl_Input_ base class. +09/25/96: All constructors of the form Fl_x(x,y,w,h,label=0). +09/16/96: More changes to Fl_Input, fixed the scrolling behavior, + made it not crash if you paste huge amounts of text in. +09/11/96: Fixed minimal update when you resize a subwindow. +09/10/96: Constructor no longer does add(). +09/07/96: FL_SHORTCUT is sent mouse window rather than focus window +09/07/96: Added ^Z=undo, ^X=cut, ^C=copy ^V=paste to Fl_Input, and + made double-click select words and triple-click select lines. +08/23/96: Tries to send maximum size in XSizeHints + +FL-0.91 + +08/21/96: fluid uses Fl_Overlay_Window +08/20/96: Added Fl_Overlay_Window +08/19/96: Added Fl_Double_Window to provide double buffering +08/19/96: Documentation for subclassing windows +08/15/96: Fixed bugs with overriding resize() on Fl_Window +08/15/96: Erases menus before unmap, to fix colormap flash on O2 +08/14/96: Replaced <strings.h> with <string.h> +08/14/96: Added makeinclude.svr4 (tested on a "SINEX-Z" os) +08/14/96: Added scandir.c from the GNU C library for SVR4 +08/13/96: makefiles have LIBNAME, VERSION, and REVISION switches +08/13/96: added (completely untested!) makeinclude.linux.so to make + a shared library. I recommend however that if you are making + programs for any kind of distribution that you use the static + version of the library, rather than relying on users correctly + installing the shared one! +08/13/96: fixed *many* occurances of wrong scoping of for(int x;;) +08/13/96: patched out warning messages for enumerations from gcc. +08/13/96: fixed crash for fixed-pitch XFonts (per_char ptr is NULL) +08/13/96: some fixes to Fl_Chart so output matches Forms. +08/13/96: Insure radio button not pressed if mouse released outside it +08/13/96: Clicking in the value box of a Value_Slider does not move slider. +08/13/96: Added switches so arrows can't navigate between text fields +08/13/96: Initializes some stuff it should have in Fl_Menu_Button. +08/13/96: Non-multiline Fl_Inputs do not treat ^J characters as + special, for instance ^K always deletes to the end even if + there are imbedded newlines. +08/13/96: Tab inserts a tab in Fl_MultiLine_Input. Use Ctrl+Tab to navigate +08/10/96: renamed from libFL to libFl to avoid existing SGI library +08/10/96: the static Fl_Object method readqueue has been moved to + a method on the Fl object. +08/10/96: the static Fl_Object method draw_box() renamed fl_box() and + put in Draw.H +08/10/96: fl_label_bitmap has been renamed fl_draw and put in Draw.H +08/10/96: fixed the deactivated menu items to not draw over the right edge. +08/09/96: fl_clip works in both X and GL windows when USE_X is defined. +08/09/96: the static Fl_Object methods event_inside and test_shortcut + have been moved to methods on the Fl object. + The static Fl_Object method shortcut_text has been renamed + to a function fl_shortcut_text and put in the Draw.H header. +08/09/96: many internal changes to Fl_Group and Fl_Window to support + minimal update. expose() is no longer a virtual function and + is private to Fl_Window. Fl_Object::flush() and qredraw() + deleted. New methods: draw_child(), redraw_child(), and + done_drawing(), for calling by draw() implementations. + See (not yet written) drawing documentation. +08/05/96: to make it possible to do minimal update, Fl_Group must draw + everything outside of the object's bounding box. So draw_label() + changed to only draw FL_INSIDE or FL_CENTER alignements. New + method draw_outside_label() added to be called by Fl_Group + to draw the other labels. This simplified Fl_Slider and + Fl_LightButton some, too. |
