    notification of mouse hovering on edit

    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

    Or you could use subclassing:

    Code:
    // 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.
