[OT] insert swing or swt widgets in gef editor [message #123253]

Hi.

First of all excuse me for my bad english. I think this is not a VE
question, but I don't know where else to ask. I also have tried to ask
this in the GEF newsgroup but they didn't reply.

I know that the Visual Editor was developed using GEF (graphic eclipse
framework). Well, I'm developing a visual editor using GEF and I need to
add swing or swt widgets to the editor. But as I know, GEF only let me add
IFigures. I would like to know how you add swing and swt components in VE
using GEF. I looked in VE source code, but I couldn't find the gef edit
parts corresponding to any swing/swt widget.

Well, hope you understand. Thanks in advance.

The VE doesn't add Swing/SWT to GEF. It uses IFigures and gets a
snapshot image of the Swing/SWT component and gives it to an IFigure
that takes an Image.

First of all, thanks Rich for the info. I would like more information about how to take these "snapshots". Basically I would like to take snapshots to swing widgets. I'm investigating the java.awt.Component's createImage() methods, but I really don't know how to use them. I know this is an OT, but I would apprecciate if somebody tell me what is the Visual Editor plugin class responsible for taking these "snapshots" to the swing components.

Well, thanks in advance.

First of all, thank you very much to Jeff for the links. Lamentably, I could'n extract
the VE part that "take the snapshot" to swing components (good code but so complex!).

Nevertheless, I have developed some classes that construct a draw2d ImageFigure from
any swing component, but I think is less efficient that VE mechanism. I use a standar
format (png) for the transition of AWT BufferedImage to SWT Image but this transition
is done in memory, so the efficience is yet aceptable. People interested can download
this classes from http://cancerbero.0moola.com/source/swingInGEF.zip.

Sadudos!
