Hi All
Q: How to force GraphicalEditor to be Dirty
I am using GEF GraphicalEditor just to display my model, without any
palette. I have a GraphicalEditor actions contributed through
ActionBarContributor. When users click on this action button, the program
updates the model and visuals. As I am not using any commands to update
the model, the GraphicalEditor is always un-dirty.
In the action class [extends SelectionAction], am able to get model
editparts. At this class I wanted to set my GraphicalEditor to Dirty
after I update the model programmatically.
Can you please advice me, whether it is possible to do so?
My GraphicalEditor has:
public boolean isDirty() {
return dirty;
}
public void setDirty(boolean value) {
dirty = value;
firePropertyChange(IEditorPart.PROP_DIRTY);
}
MyActionClass has:
private boolean canPerformAction() {
boolean canPerformActionStatus = false;
if (getSelectedObjects().isEmpty()){
canPerformActionStatus = false;
}else{
List selectedEditParts = getSelectedObjects();
for (int i=0; i<selectedEditParts.size(); i++){
Object selectedObject = selectedEditParts.get(i);
if (selectedObject instanceof EditPart)){
canPerformActionStatus = true;
}
}
}
return canPerformActionStatus;
Thanks for your Hellp
Cheers
DJ

The simplest option is probably to execute a dummy command on the command
stack.
