Windows: From full-screen to windowed leaves ugliness?
Author
Hey there. I''m working on this windows encapsulation thing, and I''m trying to implement a full-screen/windowed mode toggle function, and it works to an extent.
The thing is that it toggles to full-screen mode fine. The window changes to WS_POPUP style and fills the screen. Going back to windowed mode (or starting in full-screen and toggling to windowed) works as well, yet it doesn''t redraw the area around my window. This results in the entire screen, apart from my window, being filled with whiteness (the full-screen window was all-white), and when I drag the window around, the desktop (or whatever window was behind it) becomes visible where my window used to be. So you end up having to ''polish'' your desktop with my window to get rid of all the whiteness.
I''m sure there''s something you can do to make windows redraw the entire screen, but I don''t know what. I''ve checked MSDN and Google on the SetWindowLongPtr and SetWindowPos functions, but I don''t see anything on screen redraws.
Here''s my code:
As said, this gives me a 100x100 window at 100,100 when toggling to windowed mode, but the rest of the screen doesn''t redraw and still shows what''s left of the full screen window. Anyone who can set me on the right path?
Which API are you using? DX or OpenGL? Or Neither!?
To tell you the truth, your code looks quite strange...

Eh? I'm not using a graphics API, this is all just basic Windows stuff. I would've posted in the appropriate forum if I was using either D3D or OpenGL.
And what's strange about my code? The m_Windowed member specifies if the current window is Windowed or Fullscreen. When the toggle function is called, m_Windowed is negated, and based on its new value, the window's style attribute is changed (POPUP or OVERLAPPED) and the window is resized and placed in a new position. Nothing strange or exotic I can see.
So why does it look strange? It would be a bit more helpful if you said why it looks strange, in stead of just saying that it does.

OK, not strange, but different. I see why now.
Perhaps distroying the window and recreating it might work better. I am not a winapi guru, I thought it was some sort of 3D API bug (that code is not going to win you any friends if you are using OGL/D3D)
Anyway. Carry on.
