Module Name:

|
PaletteRestore.cpp
|
|
|
|
Abstract:
|
|
|
|
On win9x, all palette state was maintained through a mode change. On NT,
|
|
this can cause numerous problems, most often when task switching between
|
|
the application and the desktop.
|
|
|
|
Unfortunately, GetSystemPaletteEntries does NOT return the peFlags part
|
|
of the PALETTEENTRY struct, which means that we have to intercept the
|
|
other palette setting functions just to find out what the real palette
|
|
is.
|
|
|
|
The strategy is as follows:
|
|
|
|
1. Catch all known ways of setting up the palette
|
|
2. After a mode change, restore the palette
|
|
|
|
In order to do this, we also have to keep a list of the DCs so we know
|
|
which palette was animated/realized and the active window to which it
|
|
belongs.
|
|
|
|
Not yet implemented:
|
|
|
|
1. Track whether a palette change came from within DirectDraw, since on
|
|
win9x, DirectDraw doesn't use GDI to set the palette, so calls to
|
|
GetSystemPaletteEntries will return different results.
|
|
|
|
Notes:
|
|
|
|
This is a general purpose shim.
