Hello, I've just implemented a "toggle between windowed and fullscreen mode" option in my game, but I noticed something weird. When the app is in fullscreen mode and I hit the Print Screen key, the window appears to be in it's old location (before fullscreen mode was set). Here's an image to better explain:
As you can see I'm setting the window position to (0, 0, ScreenWidth, ScreenHeight) so I don't know what could be causing this :(
bool Window::SetFullScreen(bool fullScreen)
{
if (!p_Created) return false;
p_FullScreen = fullScreen;
if (p_FullScreen)
{
if (!p_Resolution->ChangeResolution(p_ClientWidth, p_ClientHeight)) return false;
p_SavedClientLeft = p_ClientLeft;
p_SavedClientTop = p_ClientTop;
p_SavedClientWidth = p_ClientWidth;
p_SavedClientHeight = p_ClientHeight;
SetWindowLong(p_Handle, GWL_STYLE, WS_POPUP);
SetWindowLong(p_Handle, GWL_EXSTYLE, NULL);
p_Left = 0;
p_Top = 0;
p_ClientLeft = 0;
p_ClientTop = 0;
p_Width = p_Resolution->GetWidth();
p_Height = p_Resolution->GetHeight();
p_ClientWidth = p_Resolution->GetWidth();
p_ClientHeight = p_Resolution->GetHeight();
if (!SetWindowPos(p_Handle, HWND_TOPMOST, p_Left, p_Top, p_Width, p_Height, SWP_NOMOVE | SWP_NOSIZE | SWP_FRAMECHANGED | SWP_SHOWWINDOW)) return false;
}
else
{
if (!p_Resolution->RestoreResolution()) return false;
SetWindowLong(p_Handle, GWL_STYLE, p_Style);
SetWindowLong(p_Handle, GWL_EXSTYLE, p_ExStyle);
AdjustWindow(p_SavedClientLeft, p_SavedClientTop, p_SavedClientWidth, p_SavedClientHeight);
if (!SetWindowPos(p_Handle, HWND_NOTOPMOST, p_Left, p_Top, p_Width, p_Height, SWP_FRAMECHANGED | SWP_SHOWWINDOW)) return false;
}
return true;
}
