Icon on window taskbar

With this trueframeless windows i'm not succeed to add icon for the taskbar.

I tried : 

`RC_ICONS = icon.ico in the .pro`

I tried : 

```
HICON hWindowIcon = LoadIcon(GetModuleHandle(NULL), strVariable2);
	SendMessage(hWnd, WM_SETICON, ICON_SMALL, (LPARAM)hWindowIcon);
	SendMessage(hWnd, WM_SETICON, ICON_BIG, (LPARAM)hWindowIcon);
```

no one succeed, 

Does some one try ?
