Interface Border

public interface Border

The class is responsible for defining and rendering borders. Border size is defined by insets.

Borders can be opaque. If true, then the border has to care about painting all pixels in borders. If false, then the widget background is painted under borders too.

This can be used for non-rectagular shapes of borders e.g. returning true from isOpaque and drawing a filled rounded rectangle.

Method Summary

Insets getInsets()
          Returns layout insets.

boolean isOpaque()
          Returns whether the border is opaque.

void paint(Graphics2D gr, Rectangle bounds)
          Paints the border to the Graphics2D instance within specific bounds.

Method Summary
`Insets`	`getInsets()` Returns layout insets.
`boolean`	`isOpaque()` Returns whether the border is opaque.
`void`	`paint(Graphics2D gr, Rectangle bounds)` Paints the border to the Graphics2D instance within specific bounds.

Method Detail

getInsets

Insets getInsets()

Returns layout insets. Insets has to be the same during whole life-cycle of the border.

Returns:: the insets

paint

void paint(Graphics2D gr,
           Rectangle bounds)

Paints the border to the Graphics2D instance within specific bounds. Borders are always painted immediately after the widget background and before the widget painting itself.

Parameters:: gr - the Graphics2D instance; bounds - the boundary

isOpaque

boolean isOpaque()

Returns whether the border is opaque. The result of the method controls whether a widget background is painted under the border insets too.

Returns:: true, if background is painted under the border insets.
