Disable Image Decorators [message #1228548]

Hello everybody,

I have implemented my collapse function. When I collapse a rectangle, everything inside it has do dissapear (I change the height of the rectangle and everything inside the rectangle dissapears, perfect). The problem is that the decorators of the connections (the connections belong to the diagram not to the rectangle) remains visible.

Here it is what I have:

if (pCollapse.getValue().equals("false")) {
				cs.getGraphicsAlgorithm().setHeight(40);
				for(Shape s : cs.getChildren()){
					if(s.getLink()!=null) {
						for(Object ob : getFeatureProvider().getAllBusinessObjectsForPictogramElement(s.getLink().getPictogramElement())){
							if(ob instanceof transML.AnalysisLang.Object){
								for(Object f : ((transML.AnalysisLang.Object) ob).getFeatures()){
									if(f instanceof Reference){
										for(PictogramElement pe : getFeatureProvider().getAllPictogramElementsForBusinessObject(f)){
											pe.setVisible(false);
											if(pe instanceof FreeFormConnection){
												FreeFormConnection ffc = ((FreeFormConnection)pe);
												for(ConnectionDecorator cd : ffc.getConnectionDecorators()){
													cd.setVisible(false);
												}
											}
											
										}
									}
								}
							}
							
						}
						
					}
				}
				pCollapse.setValue("true");
			}
			
			else if (pCollapse.getValue().equals("true")) {
				for (Property p2 : cs.getProperties()) {
					if (p2.getKey().equals("PATTERN_HEIGHT")) {
						cs.getGraphicsAlgorithm().setHeight(
								Integer.parseInt(p2.getValue())+AddPatternFeature.TEXT_SPACE);
						
						for(Shape s : cs.getChildren()){
							if(s.getLink()!=null) {
								for(Object ob : getFeatureProvider().getAllBusinessObjectsForPictogramElement(s.getLink().getPictogramElement())){
									if(ob instanceof transML.AnalysisLang.Object){
										for(Object f : ((transML.AnalysisLang.Object) ob).getFeatures()){
											if(f instanceof Reference){
												for(PictogramElement pe : getFeatureProvider().getAllPictogramElementsForBusinessObject(f)){
													pe.setVisible(true);
													if(pe instanceof FreeFormConnection){
														FreeFormConnection ffc = ((FreeFormConnection)pe);
														for(ConnectionDecorator cd : ffc.getConnectionDecorators()){
															cd.setVisible(true);
														}
													}
												}
											}
										}
									}
									
								}
								
							}
						}
						pCollapse.setValue("false");
					}
				}
			}

I tried to setActive(false) and then setActive(true) to the connection decorators. It worked but when I expand the collapse rectangle, the connection line and the connection arrow are separated. I can click and move the arrow like if it does not belong to the line and 2 decorators appears (1 on the line and the other on the arrow. The same one).

Please any ideas?

Best regards.

Victor.

Hi Victor,

from a first glance into the coding it seems that for connection decorators
the check for isVisible is missing on refresh. Would you please file a
bugzilla to track the issue?

Thanks for the answer. I think I explained wrong myself. When I say connection decorators I mean the decorators implemented in the ToolBehaviourProvider (the warning and error icons that are asociated to the connection in this case).

If it is clear now I will file it.

Victor,

sorry, connections and decorators put me in the wrong direction...

You will have to find out by yourself, if the representation is collapsed or
not when providing the decorators in your tool behavior provider. Maybe you
should set a custom property "collapsed" to distinguish more easily.
Graphiti itself only triggers the refresh of the decorators but cannot tell
if they should be hidden in that special case.
