Restricting SDL to a Panel within a Window

SDL Development
1

Hi All,
One of the members of the JEDI-SDL mailing list is having a problem
when trying to restrict the output of SDL to a Panel. If he uses…
SDL_putenv(‘SDL_VIDEODRIVER=windib’);

Everything works fine but if he tries…
SDL_putenv(‘SDL_VIDEODRIVER=directx’);

it crashes.
Does anyone have any suggestions as what may be causing the crash.

Thanks,

SDL has nothing called “Panel”. Post a minimal, complete testcase (in C)
and we will look at it

DirectInput (which is used with SDL_VIDEODRIVER=directx) won’t work if you
initialize it with an hwnd that was created with the WS_CHILD style. As
far as I know, there’s no way to tell SDL to use directx for the video
stuff, and the old windows input routines, so you can only do it with
SDL_VIDEODRIVER=windib.

Yes a Panel is effectively a WS_CHILD has it acts like a container
control within Delphi applications.

Does anyone know if there is likely to be a work around for this at some
point?

Thanks for the information this clears up a lot.
