ToolTip on GDI+ figure

[r9]

It is possible to put a tooltip on a GDI+ figure? (on mouseOver) The tooltip1.SetToolTip() method takes in a System.WindowsForms.Control, but there is no overload for a GDI drawing ?

1). Declare global variables ToolTip tt; and bool installed = true; 2). Initialize tt in constructor of the form: tt = new ToolTip() 3). Override OnMouseMove:

protected override void OnMouseMove(System.Windows.Forms.MouseEventArgs e)
{
if (bounds.Contains(e.X, e.Y))
{
this.Cursor = Cursors.Hand;
if (installed)
{
tt.SetToolTip(this, "Hello, r9 :o)");
installed = false;
}
}
else
{
this.Cursor = Cursors.Default;
if (!installed)
{
tt.RemoveAll();
installed = true;
}
}
base.OnMouseEnter(e);
}

You are genius :-) With all your help, I am getting better and better at understanding GDI+. Thanks

Do you code a control or you just draw shape on the form? All code examples supposed to work for the shape drawn on the form. If you want to use examples to code a control, you should make some changes (some lines are not necessary and some things should be coded in other way).

I have a pictureBox on my Form. Then I use the graphics object from the PictureBox_paint event: .. graphicsObj = e.Graphics; ..
