Drawing the Frame

INDEX PREVIOUS NEXT

The IlvManagerFrame interface defines a method to draw the frame:

void draw(IlvManager manager, IlvRect bbox, Graphics g, IlvTransformer t) 

This method already provides the manager, with its bounding box in the view coordinate system that already takes the margins into account. The IlvDefaultManagerFrame fills the background and draws a border around the manager. It also draws a title at the top of the manager that corresponds to the name of the manager, as you can see in the picture above (Figure 1.5).

boolean isOpaque(IlvManager manager) 

• If the frame is opaque, graphic objects under the nested manager are hidden. This disallows manipulation of these graphic objects.
• If the frame is not opaque, graphic objects under the nested manager are visible. This allows manipulation of the graphic objects, whether covered by the frame or not.
