public class IconBar

extends Composite

implements IIconBar, org.eclipse.swt.events.DisposeListener

An icon bar like a ToolBar but can scroll and have more control of the appearance. The IconBar is actually a viewport on a Canvas where the icons located. And thus most operations (layout,key,mouse ... etc) are forwarded to the Canvas where interactions occurs. Default highlight is changing icon background color on enter instead of simulating a button. Also fix problem that ToolBar icons flash on enter/exit by custom Canvas with NO_BACKGROUND. Subclass can use setMouseEventHandler() and access to the layout parameters to install different highlight behaviour. Subclass can use setRenderer() to install a renderer to customize how icons are painted. For example, to redraw a region in the Canvas: paintBuffer(getBackBuffer(),x,y,w,h); getCanvas().redraw(x,y,w,h); Usage: IconBar iconbar = new IconBar(parent, SWT.NONE); iconbar.setBackground(bg); iconbar.setIconBackground(iconbg); iconbar.setLayout(new IconBarLayout(4, 0, 0, 2, 2, SWT.LEFT));
