GUI Builder - best approach [message #11358]

Hello !

We began the development of a GUI Builder for SWT/JFace. The problem we are
facing now is how to represent the components (the Button for example) on
the surface of the builder? It can't be the actual components because of the
events. We thought about subclassing the components, but some are not
allowed to be subclassed and other are marked as intended to be subclassed
only within the SWT implementation.

So, what is the best approach for doing something like this?

Thanks!

Stelian

Use the draw2d library included in the GEF plugin. I think it's designed
for just that. Many of the standard SWT components like buttons are already
implemented in the draw2d lightweight framework and I think more are on the
way.

We don't plan to reproduce the widgets that are available in the platform.
Our Button is slightly more flexble than the OS button, and was necessary
for simple things like scrolling a figure.

However, as I replied on the other forum, you could use dummy Figures simply
for the purpose of targeting, hit-testing, and the ability to paint stuff on
top of the widgets like handles the Grid from GridLayout. These figures
would paint by capturing the SWT representation, not emulating it. This is
exactly the approach taken by some Swing/AWT Gui builders.

Randy you said "These figures would paint by capturing the SWT
representation". How would one go about doing this? I (also) am building a
sort of GUI builder and I'm just reaching this point now.

Thanks
Zac

See the SWT FAQ. Or, look at what you can do with control.getGC().
