Description Jennifer Cormier CLA 2006-02-16 11:02:06 EST 
By adding the attached file to draw2d, figures on FigureCanvas's can be made selectable.  This will be very useful to people using draw2d who do not want the overhead of GEF, but do want to utilize Eclipse' selection and context menu features.

The file, SelectableFigureCanvas.java, which implements ISelectionProvider on a FigureCanvas, is attached.

Please consider adding this to org.eclipse.draw2d or another appropriate location within draw2d.  I will be happy to help with documentation or anything else to move this forward because I feel it will be a very valuable addition to Eclipse / draw2d.  There is an interest, as evidenced by many posts including the following:

Thanks!

If we start adding behavior for selecting figures, what's next? Moving them around? Context menus? This is what the org.eclipse.gef plug-in is for.

Draw2d supports the notion of focus. Selection of a figure is not general enough and infringes on the support provided by the gef plug-in.

I agree that GEF is for editing and the Draw2d canvas is for viewing only.  Creating a FigureCanvas which implements ISelectionProvider further standardizes draw2d as a viewer; Eclipse context menu support is inherited for *free*.  Selection within a SelectableFigureCanvas works just like it does in other viewers such as table viewers and tree viewers - click on something to select it.

draw2d does not have any dependencies on JFace.
