change figure associated with an edit-part dynamically [message #225322] Mon, 30 October 2006 13:49 Go to next message

Hi,
I have this scenario wherein I need to change the figure associated with an
edit-part. What I do in the concerned edit-part is:

Map partMap = getViewer().getVisualPartMap();
partMap.remove(oldFigureInstance);
partMap.put(newFigureInstance, this);

This however has no effect and the old figure persists in the viewer. Is
there a central place wherein I can update the EditPart to Figure mapping?
How do I change the figure associated with an edit-part dynamically at
runtime?

Appreciate your help.

Kind Regards,
Prashanto

Hi,
Maybe Pratik and Hudson not advice you do like above yet.:)
OK, this part with an only figure, and once created, no dead if no
exception.How?
1, get parent model, remove this child model, update;
and add this model, update. It works.
2, let a Figure object contains really needed figure.
and editpart can control this parent virtual figure update status
according concret condition.

Hope this help.

Regards,

Qinxian.

Thanks for responding.

In the meantime I tried out the following sequence:
unregisterVisuals();
setFigure(newFigure);
registerVisuals();
But even this didn't work :(. I get the old figure with connections and the
new Figure without the connections.

This is baffling. I was wondering whether GEF has any update mechanism that
automatically updates any mappings with the corresponding figure?

Any help would be appreciated.

Regards,
Prashanto

Hi,
This way could work yet, try to get a place update it or notifiy it's
update.
Try to add refreshVisuals();

Hi,
I already have that. I call refresh() which calls both refreshVisuals() and
refreshChildren(). But still it does not help :(

There's a simple solution to this. In your createFigure() method, first
create a figure with a stack layout. In there, you put the figure that you
expect to be changed. Then, simply switch that figure whenever you need to,
leaving the parent figure (the one returned by getFigure()) alone. It gets
trickier if this editpart can have children.

Hi Pratik,
Thanks for your response. I have done as you had suggested and it works like
a wonder.

However, I have one single doubt. What I've currently done is:

------------------------------------------------------------ ------------------------------------------------------------ ------------------
protected IFigure createFigure() {
stackFigure = new Figure();
stackFigure.setLayoutManager(new StackLayout());

stackFigure.add(_insertionPointFigure = new
ImageFigure(InsertionPoint.INSERTION_POINT_IMAGE.createImage ()));
stackFigure.add(_enabledBreakpointFigure = new
ImageFigure(InsertionPoint.ENABLED_BREAKPOINT_IMAGE.createIm age()));
stackFigure.add(_disabledBreakpointFigure = new
ImageFigure(InsertionPoint.DISABLED_BREAKPOINT_IMAGE.createI mage()));

resetFigure();

if (getModel() instanceof TreeNode) {
stackFigure.setToolTip(((TreeNode)getModel()).getToolTip());
}
return stackFigure;
}
------------------------------------------------------------ ------------------------------------------------------------ ------------------

followed by:

------------------------------------------------------------ ------------------------------------------------------------ ------------------
public void resetFigure() {
if(getCastedModel().containsBreakpoint()){
if(getCastedModel().isBreakpointEnabled()){
stackFigure.add(_enabledBreakpointFigure);
}else{
stackFigure.add(_disabledBreakpointFigure);
}
}else{
stackFigure.add(_insertionPointFigure);
}
}
------------------------------------------------------------ ------------------------------------------------------------ ------------------

Is this the correct way to use a StackLayout? Why isn't there an option for
something like a top-control in StackLayout?

Thanks once again.

Regards,
Prashanto
