CEGUI X-Plane integration - coordinate system

[Rhard]

Hi Team,

I have integrated CEGUI in X-Plane flight simulator (it was really a challenge ).
But since X-Plane 2D drawing uses left-bottom corner as zero position I need always to make y-position recalculations (for the mouse, callbacks etc.)

Is it a possibility to setup CEGUI to use bottom-left as zero point? Maybe some setup during build step? Or simplest way to change the source if possible?

Thanks.

This is not supported in the way you described. If it is just about drawing (wrapping the input really shouldn't pose a challenge anyways) then why can't you do it like we did with OpenGL Renderers and just flip ever quad vertically? There is an option for that somewhere I think it is called "isTexCoordSystemFlipped" (dont know the exact name in v0-8) or similar - I suggest to check how it is used. Afaik this is only used in the OpenGL Renderers, the other Renderers work the Direct3D way and assume the origin is top-left, just like CEGUI does.

If it works for OpenGL then why shouldn't it for X-Plane - in case I overlooked something tell me what I missed. For example, maybe this only works on a per-texture basis but not for the whole framebuffer. In that case you might wanna flip the framebuffer drawing as well.
