SDL_VIDEO_WINDOW_POS on OSX broken

SDL Development
1

Hi,

it seems that SDL_VIDEO_WINDOW_POS doesn’t work on OSX.

If I move it off the x coordinate, then shows white screen on the left side
of the window by the same amount. This is with x=300, y=0 for example –
there is white on the window for 300 pixels across.

Moving it on the y axis I get a bus error.

with last stable… SDL 1.2.13, OSX 10.5.7

cheers,

Can you report a bug in bugzilla? http://bugzilla.libsdl.org/

Thanks!

hi again,

It looks like the parent window isn’t moved with the main SDL window.

The bus error crashes with SDL_FillRect if I change the y coordinate.

This is the file where SDL_VIDEO_WINDOW_POS is inspected…
src/video/quartz/SDL_QuartzVideo.m

It looks like the patch addresses it using some carbon calls:
http://www.nabble.com/-patch--OS-X-carbon-SDL_WINDOWID-support-td6457591.html

Haven’t tried the patch though.

ps. SDL_VIDEO_CENTERED=1 works fine.On Wed, May 27, 2009 at 4:31 PM, Ren? Dudfield <@Rene_Dudfield> wrote:

one last thing…

export SDL_VIDEO_WINDOW_POS=“0,0” works ok, since then the parent
window doesn’t need to be modified… as it starts off at 0,0 by
default.
