#9185 new bug

BDirectWindow::SupportsWindowMode() doesn't check for hardware cursor support

Reported by: jua Owned by: jackburton
Priority: normal Milestone: R1
Component: Kits/Game Kit Version: R1/alpha4.1
Keywords: BDirectWindow hardware cursor Cc: rudolfc

Has a Patch: no Platform: All

Description

According to the BeBook, windowed mode for BDirectWindow should only work when the graphics accelerant supports hardware cursors (see the documentation on BDirectWindow::SupportsWindowMode()).

SupportsWindowMode() is supposed to check for it, however, in Haiku it only looks for B_PARALLEL_ACCESS. Using a BDirectWindow without hardware cursor causes any drawing in it to even draw over the mouse cursor.

The attached patch adds B_HARDWARE_CURSOR to the check.

I just learned about this ticket: http://dev.haiku-os.org/ticket/4356

If #4356 is implemented, this patch is not necessary anymore, because then hardware cursor is not a requirement for BDirectWindow... (although then there is no cursor in it).

Applying this as is would essentially make windowed BDirectWindow unusable, since very few of our drivers support hardware cursors. We should probably fix that first.

Guys,

Let it please be noted that my drivers all have 100 procent correct working hardware cursors under beos version 5 and dano. These drivers are: Nvidia, matrox, neomagic and via. If its not working correctly, the problem lies somewhere else.

Bye!,

Rudolf.

BTW,

For these driver's there is HTML doc in the respective kerneldriver source folders, alongside the settings files for these drivers (all same style).
