Window always appears on secondary monitor

[Sauce]

I'm using OGRE 1.8 with the D3D9 RenderSystem, and when I create my application window, it is always spawned on the secondary monitor when 2 monitors are available. I've reproduced this on 2 other machines with a dual-monitor setup. My previous project, which used OGRE 1.71 didn't have this issue. I know there has been work on the render systems since 1.7, and was wondering if there have been any changes to the code that determines window positioning for this rendersystem. I haven't tested 3+ monitors but I suspect the window would always spawn on the n'th monitor instead of the primary. This is happening both in fullscreen and windowed mode.

I've had a look at OgreD3D9Renderwindow.cpp and couldn't determine the cause. Maybe someone else knows what's going on.

My window creation...

Code: Select all

m_pWindow = m_pOgreRoot->createRenderWindow("title", width, height, isFullscreen);
m_pWindow->setVisible(false);

//Other initialisation...

m_pwindow->setVisible(true);

Nothing fancy here - I'm just using the default window positioning OGRE gives me.

Upon further inspection, it seems RenderWindow::setVisible() is just a stub. I find that strange because I recall being able to show/hide windows a few months ago. It shouldn't have any effect on my problem though.

Usually, the monitor it appears on is set in the ogre config dialog at the beginning.

On mine in 1.8 I have the Rendering Device entry in the dialog, which has the options of "Monitor-1-ATI Radeon HD 5800 Series", "Monitor-2-ATI Radeon HD 5800 Series" and "Monitor-3-ATI Radeon HD 5800 Series".

good point. I'm not using the default ogre configs so this is something I overlooked when passing my settings on to ogre.

When creating your own render window, you can explicitly tell Ogre where to draw the window (which monitor).

It's pretty simple, just create a NameValuePairList with an element named "monitorIndex" and the desired index as the value (indices begin at 0, your main monitor would therefore be index 0, by default I believe), then pass that namevaluepairlist, as a reference, in the 5th parameter of createRenderWindow.

For example:

Code: Select all

      Ogre::NameValuePairList misc;
     [b][u] misc["monitorIndex"] = "0";[/u] [/b] //I use two monitors, so I tell Ogre to draw on my main (#1) monitor
      
// Here we tell the system not to create a default rendering window by passing 'false'
 
        mWindow = mRoot->initialise(false, "The Render Window");

//now we need to create a render window manually

      mWindow = mRoot->createRenderWindow("The Render Window",1680,1050,false, [b][u]&misc[/u] [/b]); //pass our custom attributes in "misc"

hope this helps

Thanks for the info, now i don't have to go rummage through code looking for namevaluepair options

For anybody who happens upon this thread like I did wondering why monitorIndex doesn't work for D3D11, I have patched it and submitted a pull request to fix that.
