Method Detail

setFillAreaBeforeDrawingComponents

public void setFillAreaBeforeDrawingComponents(boolean fillAreaBeforeDrawingComponents)

If setting this to false (default is true), the Panel will not reset it's drawable area with the space character ' ' before drawing all the components. Usually you do want to reset this area before drawing but you might have a custom renderer that has prepared the area already and just want the panel renderer to layout and draw the components in the panel without touching the existing content. One such example is the FullScreenTextGUITest.

Parameters:

fillAreaBeforeDrawingComponents - Should the panels area be cleared before drawing components?

getPreferredSize

public TerminalSize getPreferredSize(Panel component)

Description copied from interface: ComponentRenderer

Specified by:

getPreferredSize in interface ComponentRenderer<Panel>

Parameters:

component - Component to calculate the preferred size of

Returns:

The size this renderer would like the component to take up
