notification of mouse hovering on edit

[underthesun]

Hello all,

just wondering, if its possible to actually notice when a mouse hovers on an edit control.. As far as I know edit controls only send few notification messages.. all EN_* except for WM_CTLCOLOREDIT..

So yeah, is there a way?

thanks in advance

Would checking for a WM_MOUSEMOVE Notification suffice? Perhaps you could just check the (X,Y) coordinates of the mouses location compared to the position/width/height of your edit.

I.e.
Is MouseX greater than EditLeft
AND
Is MouseX less than (EditLeft + EditWidth)

the thing is, this window i have is a child window, and the textbox covers all of the child windows' area..

setting the WM_MOUSEMOVE detector on the parent's window procedure doesnt seem to fix it.. mousemove wasnt really detected

I think im going to give up trying, and instead use a timer that keeps detecting the movement of the mouse and its position.. oh well

thanks for the help anyways

try TrackMouseEvent() or _TrackMouseEvent()

Or you could use subclassing:

// Global
WNDPROC OldEditProc;
LRESULT CALLBACK DummyProc(HWND, UINT, WPARAM, LPARAM);



// Inside WndProc
HWND hEdit = CreateWindow(...);
OldEditProc = (WNDPROC)SetWindowLong(hEdit, GWL_WNDPROC, (long)DummyProc);



/* This "dummy" window proc only processes the WM_MOUSEMOVE
    message. It sends all messages the the original window proc
    stored in OldEditProc */

LRESULT CALLBACK DummyProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
    if(msg == WM_MOUSEMOVE) {
        // The cursor is inside the client area of the edit window
    }

    // Make sure the edit box functions properly
    return CallWindowProc(OldEditProc, hwnd, msg, wParam, lParam);
}

I hope this makes sense. If not, just say it and I'll make a full working example.
