Dear list,



We are working on a GMF project in which we hope to do the following. We
have a very simple ecore diagram, in which there is one node type
(block) that can be placed on the canvas. Inside this node are 1 or more
sockets. Connections can only be made by connecting socket objects.

The number of different blocks are defined in an unknown number of
configuration files. The configuration file defines the number of
sockets and some other properties. For each such a configuration file,
we want to have a named entry in the palette (the name is in the
configuration file, too). The tool should read these files on startup,
as their number will increase over time.

And after experimenting for about a week now, I have not found a way to
achieve this.

Any help would be greatly appreciated.


Kind regards,



Jan

Dear list,


What it all boils down to is that I do not know which nodes will be
present at runtime. I only know that they will behave like their parent
node (the block) below. Does GMF support this? If so, can someone point
me to an example? Or should I go back to GEF? I did the QuantumDB
ER-diagram in GEF (code here: http://sourceforge.net/projects/quantum/),
where I add attributes at runtime for each column name.

Please advice.

Kind regards,

Jan

Dear list,


I am still using GMF. I modified the fillPalette function. It now adds
several entries with the same element type to the palette.

Whatever tool I select the same BlockCreateCommand is called. I
understand that. What I want to do now is to find out which tool was
invoked that caused the request to create the CreateCommand, if that
makes sense... I found this "Within your action find appropriate diagram
editor part and adapt it to GraphicalViewer; then
viewer.getEditDomain().getActiveTool()."

But it's not an action, and I think we are in the model, and not in the
edit parts.

Please help.


Kind regards,


Jan

Dear list,


I solved it by finding out about the palette in the
xxxSemanticEditPolicy and passed the tool name to a new constructor.

The tool name is
this.getHost().getViewer().getEditDomain().getPaletteViewer( ).getActiveTool().getLabel()

Then in doDefaultElementCreation I can match that name to the
configuration files and act accordingly.

Kind regards,

Jan
