Tue Jun 14 08:09:14 1994 Bob Amstadt (bob@pooh) * loader/selector.c (GetCurrentPDB): Added trivial function GetCurrentPDB() which returns the program segment prefix selector. * memory/heap.c (HEAP_Free): If free list is empty, make the freed block the free list. Fri Jun 10 07:56:49 1994 Bob Amstadt (bob@pooh) * controls/edit.c (EDIT_SetTextMsg): Do not append a newline at the end of the last line. * windows/event.c (SetCapture): Set winHasCursor if mouse capture succeeds. Jun 13, 94 martin2@trgcorp.solucorp.qc.ca (Martin Ayotte) * [controls/listbox.c] Fix bug in listbox : InsertString should call AddString if -1. * [controls/menu.c] New function GetMenuState(). * [controls/scroll.c] [windows/nonclient.c] Try to make ShowScrollBar() recalc NC_ regions. Not finished ! * [objects/text.c] Add Stub for TabbedTextOut(), which temporarely call Textout(). * [windows/keyboard.c] [windows/event.c] New function GetKeyBoardState() with an KeyStateTable array & associated handling in function EVENT_key(). Mon Jun 13 16:45:24 MET DST 1994 (erik@hacktic.nl) * [controls/menu.c] IsMenu() added. * [loader/library.c] ModuleFirst(), ModuleNext(), ModuleFindName(), ModuleFindHandle() added. * [object/gdiobj.c] IsGDIObject() added. * [miscemu/int2[56].c] bugfix: both didn't leave flags pushed on 16bit-stack. (winfile gets a bit further) * [miscemu/int16.c] Added (empty). Sat Jun 11 22:56:48 1994 Jon Tombs (jon@esix2.us.es) * windows/event.c: Added code to drop redundant motion Events in the XEvent queue. Thu Jun 9 10:55:55 MET DST 1994 Jochen Hein ( Hein@Student.TU-Clausthal.de ) * [misc/main.c misc/message.c include/texts.h] Removed the text-constants from message.c into variables which may be changed from X-resources. * [misc/main.c misc/message.c] added <locale.h> and setlocale() to main.c, used toupper() in message.c Mon, 13 Jun 94 09:41:16 -0500 Paul Bramel <paulbr@comm.mot.com> * controls/button.c ( [CR]B_LButton* ) left rc.right at full window width so click on label also activates the control (MSWin behavior) Sat Jun 11 19:05:40 1994 Olaf Flebbe (flebbe@tat.physik.uni-tuebingen.de) * include/windows.h: functions pointers can not be packed. (annoying warnings with forthcomming gcc-2.6.x) * loader/main.c (InitDLL): Fixed a printf statement. (for control.exe) (InitializeLoadedDLLs): deleted shadow definition of *wpnt. (Breaks many programs, because now COMMDLG will be initialized :-( * windows/win.c (SetWindowText): added missing breaks; (PENSATE starts) * windows/graphics.c (FloodFill): Proper boundarys. (BANGBANG starts) FloodFile_rec should be rewritten. * objects/font.c (FONT_GetMetrics): TYPO: use font->perchar only if it is defined.
