 |
|
I'm trying to find a message that's sent, or any API that alerts me when the mouse is hovered over a control. The main reason for this is so that when I make custom GUI applications that don't have a title bar, and I have to add the buttons for that. I want it to be able to change the color of them when they hover over and click on them. But I can't figure out the hover. I found the messages WM_MOUSEHOVER and WM_NCMOUSEHOVER but neither of those were specifically for a control.

What am I supposed to do, make an if statement for each pixel? There has to be another way...

No, he told you to check the lParam (Hadle to the control) of WM_MOUSEHOVER message.
You could also call ChildWindowFromPoint(Ex) on WM_MOUSEMOVE message.

So either...
| Code: |
case WM_MOUSEHOVER:
if(lParam == hExitButton) {
//make brighter to represent hover
}
break;
|
or
| Code: |
case WM_MOUSEHOVER:
POINT point;
point.x = GET_X_LPARAM(lParam);
point.y = GET_Y_LPARAM(lParam);
HWND hwndControl = ChildWindowFromPoint(hWnd, &point);
if(hWndControl == hExitButton) {
//make brighter to represent hover
}
break;
}

Yea, TrackMouseEvent is used to generate the WM_MOUSEHOVER notification. So I guess it would really be like.
| Code: |
TRACKMOUSEEVENT tme;
tme.cbSize = sizeof(TRACKMOUSEEVENT);
tme.dwFlags = TME_HOVER;
tme.hwndTrack = hWnd;
tme.dwHoverTime = 10;
TrackMouseEvent(&tme);
case WM_HOVER:
if(lParam == hExitButton) {
//brighten to represent hover
}
break;
