Check Control Information by Mouse Hovers
2011-06-28
When you move your mouse point on the screen, there are some information can be shown when you hover a control.
How can you do it? In this case we are going to use Windows From, not Web From.
This sample is from a similar case on internet:
There is a panel, then put some children controls, and the children controls are nested by one inside the other, for example, put 3 levels of nesting. We want to show the children control’s name which the controls located at the mouse point place when mouse hovers somewhere.
The sample code is like:
private Control GetControlAtPoint(Control ctl, Point location)
{
Control retV = ctl;
foreach (Control child in ctl.Controls)
{
Rectangle rec = child.RectangleToScreen(ctl.DisplayRectangle);
if (rec.Contains(location))
retV = GetControlAtPoint(child, location);
}
return retval;
}
private void panel1_MouseMove(object sender, MouseEventArgs e)
{
Control ctl = GetControlAtPoint(panel1, panel1.PointToScreen(e.Location));
Console.WriteLine(ctl.Name);
}
