#5 System_Shutdown() crashes if windowed/fullscreen is toggled

[Pedro Luchini]

To replicate the problem:
1. Start the program in fullscreen mode.
2. Change HGE_WINDOW system state to true.
3. Close the program.

System_Shutdown() will crash during the DestroyWindow()
function call. I've tracked down the problem to
system.cpp, around the following line:

if(hwnd)
{
//ShowWindow(hwnd, SW_HIDE);
//SetWindowLong(hwnd, GWL_EXSTYLE,
GetWindowLong(hwnd, GWL_EXSTYLE) | WS_EX_TOOLWINDOW);
//ShowWindow(hwnd, SW_SHOW);
DestroyWindow(hwnd);
hwnd=0;
}

Hmmm... My App never crash, because I use HGE_EXITFUNC for
correct shutdown.

bool QuitFlag = false;

void ToggleScreen()
{
if (hge->Input_GetKeyState(HGEK_ALT) &&
hge->Input_GetKey() == HGEK_ENTER)
hge->System_SetState(HGE_WINDOWED,
!(hge->System_GetState(HGE_WINDOWED)).bool_value);
}

bool QuitQuery(void)
{
QuitFlag = true;
return false;
}

bool FrameFunc(void)
{
ToggleScreen();
...
// Logic & Render
...
return QuitFlag;
}

//...WinMain...
hge->System_SetState(HGE_EXITFUNC, QuitQuery);
hge->System_SetState(HGE_FRAMEFUNC, FrameFunc);
//...

Maybe engine need same flag as QuitFlag as easy solution?

stingerx,

I use that same strategy (a "quit flag" which is set to true
in the exitFunc).
