Problems with windowed mode

ELFanatic · 2007-06-05T14:18:44

I have an issue with clipping in windowed mode. I think pictures would explain best. Okay, so this is what the picture looks like in the middle of the screen. The picture itself is irrevelent. Now I move it to the right (or bottom) and it looks normal. It's what you'd expect, the right side is clipped off. but when I move it to the left, the left side of the window is clipped like it should be but the right side of the picture is clipped off again. I'd like to fix it so that the side that is off screen is the side that is clipped from the picture. I'm not sure if it's relevent but I'm using the ID3DXSprite helper class. I'm not sure where the problem is. Oh, something weird that I've noticed. As I drag it to the left it's okay but when I release the mouse button it redraws with this weird clipping. BUT the entire time I'm moving the window back onto screen from the left it acts weird like this. Some reason it's normal when dragging it out of screen to the left until I let go. Any help would be appreciated.

I have one monitor. Cool. Thanks for writing the code. I'll look through it tonight and see where I screwed up.

Here is one program I wrote that do same thing you need. It works perfectly.
Anyway, maybe it is not so important, but you have one or two monitors?

it does indeed clip correctly. some reason though, when I move it off screen and then drag it back, the clipped portion is black until I release the mouse button. Still, thank you greatly. This will hopefully help me figure out what I'm doing wrong. Thank you again.

That is because of window messages. When you click and drag on non-client area program doesn't have time to render. That is why is there "black screen". It is not rendered. But as soon as you release the mouse button render starts again.

I figured out the problem. For the presentation parameters I put

D3Dpp.BackBufferWidth = WINDOW_WIDTH;
D3Dpp.BackBufferHeight = WINDOW_HEIGHT;

Rather than assigning them to 0. Took me a little while to figure it out. Does anyone know why this makes such a difference?
