A User Drawn Header allows the developer to take over complete control of the presentation of the header portion of the control.
The User Drawn Header event fires before the header porition is drawn in the control, allowing the developer to override the display. The event passes an e argument that contains the following custom properties …
· e.Control (of type Control): The control that triggered the tip.
· e.Graphics (of type System.Drawing.Graphics): A handle to the graphics object responsible for drawing the control. Through the e.Graphics object the developer has access to the GDI+ methods for drawing objects to a display device.
· e.PaintHeader (of type Boolean): Determines if the internal routines of the control should draw the header portion of the tooltip. When the PaintHeader property is set to False the control does not execute its internal paint routine and the developer has control over the painting of the header portion.
· e.Rect (of type System.Drawing.Rectangle): A rectangle representing the area being painted in the control. The rectangle is defined by an X,Y coordinate (top left of rectangle) and a width and height of the area being painted. All values are in pixels.
· e.ToolTips (of type dbiTipsObject): A reference to the dbiTipsObject being painted.
