Window positioning?

SDL Development

Is there any way to give absolute position to an SDL window? I’m
launching external SDL-based apps from one central one and I need frameless
windows to appear in very specific areas… :frowning:

I can think of two ways to do it, neither use SDL.

  1. setup the window manager (assuming you are in X windows) to always position the window (by name perhaps) at a predetermined spot on the screen.

  2. you hack SDL to add a method to move the window via XMoveWindow, or you use the platform specific elements in SDL that have the window reference and call XMoveWindow yourself.

I any case, there’s no good portable way of doing this, that I can see, in the current implementation of SDL.–

Assuming you are doing this on X11…

#include <SDL.h>

#include <SDL_syswm.h> /* For:
                        *     Functions:
                        *         SDL_GetWMInfo
                        *     Types:
                        *         SDL_SysWMinfo
                        */

#include <SDL_version.h> /* For:
                          *     Macros:
                          *         SDL_version
                          */



// ...




SDL_SysWMinfo info;
SDL_VERSION(&(info.version));
if ( -1 == SDL_GetWMInfo(&info) ) {
    printf("Error getting WM info: %s\n", SDL_GetError());
    exit(1);
}


// Move the window
int x = 10;
int y = 80;
XMoveWindow(info.info.x11.display, info.info.x11.wmwindow, x, y);

It’s as simple as that.

Hope that helps.

See ya

To me, this seems like something that would be useful in SDL. Any reason
why it couldn’t be added?> –

Hello,

Is there any way to give absolute position to an SDL window?  I'm

launching external SDL-based apps from one central one and I need frameless

[code snipped]

The code provided doesn’t check that the subsystem you’re running on
is X11, nor does it lock the display to prevent multithreaded access.

Example code can be found in the FAQ:

See ya,
