Tue Feb 1 21:14:47 1994 Bob Amstadt (bob@pooh) * [loader/selector.c] Added function CreateNewSegments(). Modified IPCCopySelector to allow aliasing to any arbitrary memory space. * [memory/global.c] Fixed potential bug in GlobalGetFreeSegments(). * [memory/linear.c] Created functions GlobalLinearLock() and GlobalLinearUnlock(). Tue Feb 1 05:51:43 1994 julliard@di.epfl.ch (Alexandre Julliard) * [controls/widgets.c] Removed CAPTION window class. * [loader/cursor.c] Bug fix in LoadCursor(): don't allocate memory every time for built-in cursors. * [windows/clipping.c] Invalidate child windows in InvalidateRgn(). * [windows/defwnd.c] Added repaint of the caption when changing window text. * [windows/event.c] Modified SetCapture() to allow keyboard events while capturing. * [windows/message.c] New function MSG_GetHardwareMessage(), to do mouse tracking without returning control to the Windows program. * [windows/nonclient.c] A couple of changes in frame drawing for DLGMODALFRAME windows. Rewritten window moving code, to use MSG_GetHardwareMessage() instead of non-client mouse events (this is the way Windows does it), and to send WM_ENTERSIZEMOVE messages. Removed WM_NCBUTTONUP and WM_NCMOUSEMOVE handlers. * [windows/win.c] Allocate temporary structures on the USER heap instead of using GlobalAlloc(). * [windows/winpos.c] Added function WINPOS_GetMinMaxInfo() to get sizing informations. Jan 31, 94 martin2@trgcorp.solucorp.qc.ca (Martin Ayotte) * [windows/nonclient.c] Call to StdDrawScrollBar() during NC's drawing. Call to NC_ScrollBarButtonDown() on NC mouse events WM_LBUTTONDOWN. Call to NC_ScrollBarButtonUp() on NC mouse events WM_LBUTTONUP. Call to NC_ScrollBarMouseMove() on NC mouse events WM_MOUSEMOVE. * [controls/menu.c] New GetSubMenu() function. Move GetMenu() & SetMenu() functions from 'windows/win.c'. * [controls/listbox.c] Start changes to satisfy recent changes in scrollbars/windows. * [loader/resource.c] Put some code in LoadAccelerators() stub. New TranslateAccelerator() function. * [windows/win.c] Remove GetMenu() & SetMenu() functions. Call to NC_CreateScrollBars() if required by CreateWindow(). Mon Jan 24 10:40:10 EST 1994 John Richardson (jrichard@cs.uml.edu) * [window/win.c] Added functions EnumWindows, EnumChildWindows, and helper WIN_EnumChildWin. EnumWindows won't list all wine windows because GetDesktopWindow isn't complete. However, the code is in place for it to work correctly and only needs GetDesktopWindow to do so. Tue Jan 25 05:51:47 1994 julliard@di.epfl.ch (Alexandre Julliard) * [windows/defwnd.c] Added handling of activation messages (WM_ACTIVATE, WM_NCACTIVATE, WM_MOUSEACTIVATE) * [windows/event.c] De-activate the window when losing input focus. * [windows/focus.c] Bug fix in SetFocus(). * [windows/message.c] Added activation of the window on mouse-clicks. * [windows/nonclient.c] Changed non-client area painting to use the correct colors depending upon the activation state. Added WM_NCACTIVATE message handling. Fixed a couple of bugs in window moving and resizing. * [windows/winpos.c] Implemented Get/SetActiveWindow(). Implemented SWP_NOACTIVATE flag in SetWindowPos(). Jan 17, 94 martin2@trgcorp.solucorp.qc.ca (Martin Ayotte) * [misc/message.c] MessageBox has a CaptionBar for his title except for MB_SYSTEMMODAL with MB_ICONHAND. * [windows/nonclient.c] Call to NC_TrackSysMenu on SysMenu button mouse click. * [windows/defwnd.c] Call to NC_TrackSysMenu on Alt key (VK_MENU). * [controls/menu.c] New GetSystemMenu() function. New CopySystemMenu() internal function. New NC_TrackSysMenu() internal function. * [include/windows.h] New WM_INITMENU, WM_INITMENUPOPUP, WM_MENUSELECT & WM_MENUCHAR defines.
