2006-08-29 Tor Lillqvist <tml@novell.com> Remove support for Windows 9x/ME. GTK+ hasn't worked on Win9x since 2.6 or 2.8. It's pointless to keep the Win9x code in here as it isn't being maintained anyway. If somebody is interested, it can always be found in older GTK+ versions, and in CVS. * gdk/win32/gdkcursor-win32.c * gdk/win32/gdkdnd-win32.c * gdk/win32/gdkdrawable-win32.c * gdk/win32/gdkgc-win32.c * gdk/win32/gdkglobals-win32.c * gdk/win32/gdkkeys-win32.c * gdk/win32/gdkmain-win32.c * gdk/win32/gdkproperty-win32.c * gdk/win32/gdkselection-win32.c: Remove the G_WIN32_IS_NT_BASED() and G_WIN32_HAVE_WIDECHAR_API() tests and their false (Win9x) branches, and any variables or static functions used only by the Win9x branches. * gdk/win32/gdkprivate-win32.h: Remove backup definitions for constants that aren't missing from current mingw and MSVC6 headers. * gdk/win32/gdkmain-win32.c * gdk/win32/gdkprivate-win32.h: Remove the _gdk_win32_gdi_failed() function. On NT-based Windows GetLastError() returns error codes also for failed GDI calls, so we can use _gdk_win32_api_failed() always.

|

*
|
|
* Allocates a Windows device context handle (HDC) for drawing into
|
|
* @drawable, and sets it up appropriately according to @usage.
|
|
*
|
|
* Each #GdkGC can at one time have only one HDC associated with it.
|
|
*
|
|
* The following flags in @mask are handled:
|
|
*
|
|
* If %GDK_GC_FOREGROUND is set in @mask, a solid brush of the
|
|
* foreground color in @gc is selected into the HDC. The text color of
|
|
* the HDC is also set. If the @drawable has a palette (256-color
|
|
* mode), the palette is selected and realized.
|
|
*
|
|
* If any of the line attribute flags (%GDK_GC_LINE_WIDTH,
|
|
* %GDK_GC_LINE_STYLE, %GDK_GC_CAP_STYLE and %GDK_GC_JOIN_STYLE) is
|
|
* set in @mask, a solid pen of the foreground color and appropriate
|
|
* width and stule is created and selected into the HDC. Note that the
|
|
* dash properties are not completely implemented.
|
|
*
|
|
* If the %GDK_GC_FONT flag is set, the background mix mode is set to
|
|
* %TRANSPARENT. and the text alignment is set to
|
|
* %TA_BASELINE|%TA_LEFT. Note that no font gets selected into the HDC
|
|
* by this function.
|
|
*
|
|
* Some things are done regardless of @mask: If the function in @gc is
|
|
* any other than %GDK_COPY, the raster operation of the HDC is
|
|
* set. If @gc has a clip mask, the clip region of the HDC is set.
|
|
*
|
|
* Note that the fill style, tile, stipple, and tile and stipple
|
|
* origins in the @gc are ignored by this function. (In general, tiles
|
|
* and stipples can't be implemented directly on Win32; you need to do
|
|
* multiple pass drawing and blitting to implement tiles or
|
|
* stipples. GDK does just that when you call the GDK drawing
|
|
* functions with a GC that asks for tiles or stipples.)
|
|
*
|
|
* When the HDC is no longer used, it should be released by calling
|
|
* <function>gdk_win32_hdc_release()</function> with the same
|
|
* parameters.
|
|
*
|
|
* If you modify the HDC by calling <function>SelectObject</function>
|
|
* you should undo those modifications before calling
|
|
* <function>gdk_win32_hdc_release()</function>.
|
|
*
|
|
* Return value: The HDC.
