Examples

The following code example demonstrates how to custom draw the ToolTip. The example creates a ToolTip and associates it to three Button controls located on the Form. The example sets the OwnerDraw property to true and handles the Draw event. In the Draw event handler, the ToolTip is custom drawn differently depending on what button the ToolTip is being displayed for as indicated by the DrawToolTipEventArgs.AssociatedControl property.

The code excerpt below demonstrates using the DrawBorder, DrawBackground, and DrawText methods. See the DrawToolTipEventArgs class overview for the complete code example.

// Draw the ToolTip using default values if the ToolTip is for button3.
else if ( e->AssociatedControl == button3 )
{
   e->DrawBackground();
   e->DrawBorder();
   e->DrawText();
}

// Draw the ToolTip using default values if the ToolTip is for button3.
else if (e.AssociatedControl == button3)
{
    e.DrawBackground();
    e.DrawBorder();
    e.DrawText();
}

ElseIf (e.AssociatedControl Is button3) Then
    ' Draw the ToolTip using default values if the ToolTip is for button3.
    e.DrawBackground()
    e.DrawBorder()
    e.DrawText()
End If

Remarks

Use this method when you want to customize certain visual aspects of a ToolTip, but want a standard ToolTip border drawn for you using the current value of SystemColors.WindowFrame. The border is drawn to the size specified by the Bounds property. You can increase the bounds of the ToolTip before it is shown by handling the Popup event.
