LRESULT CALLBACK WndProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
PAINTSTRUCT ps;
HDC hdc;
HBRUSH oldBrush;
switch (msg)
{
case WM_CREATE:
// Initialize the window.
return 0;
case WM_PAINT:
// Paint the window's client area.
hdc=::BeginPaint(g_AppData.hWnd,&ps);//断点1
...............
DrawInfo();//断点2
EndPaint(g_AppData.hWnd,&ps);
return 0;
case WM_SIZE:
// Set the size and position of the window.
return 0;
case WM_DESTROY: return 0;
default:
return DefWindowProc(hWnd, msg, wParam, lParam);
} return 0;
}我在以上代码断点1和断点2处分别设置断点,调试时会在两个断点处循环执行,
请问WM_PAINT的执行顺序是怎样的?
