Icon in the customTask shape [message #1784623]

Hi,

I based my customTask in the dynamic example, but I don't want any icon in the shape. The I removed this code :

// add an image to the top-left corner of the rectangle
Image img = SampleImageProvider.createImage(roundedRect, customTaskDescriptor, 38, 38);
Graphiti.getGaService().setLocation(img, 2, 2);

But I still got an icon in my customTask.
How can I remove it ?

Thanks.

Hi,
have you tried

            Shape shape = containerShape.getChildren().get(0);
            // now clear all existing children of that shape...
            shape.getGraphicsAlgorithm().getGraphicsAlgorithmChildren().clear();

The containerShape has a default image which you need to remove.

Let me know if it works.

can you apply new shapes or colors? I fear you are in the wrong event and your shape is not updated after all?

Take a look at this code example:
https://github.com/imixs/imixs-bpmn/blob/master/org.imixs.eclipse.bpmn2.plugin/src/org/imixs/bpmn/ImixsLayoutTaskAdapter.java

This is the way we do it in the Imixs-Workflow project.
We replace the default image and add several custom icons.
But I have not tested it with out any image. But I do not believe this wont work because you have the full control.

Maybe one solution is it for you to add a blank place holder image?http://www.imixs.org

Thinking about the blank icon solution, if I do this, will not I get a blank icon in the palette too ?

yes that is true. But I mean that you can set the blank image explizit like this:

			Shape shape = containerShape.getChildren().get(0);
			// now we need to clear all existing children of that shape...
			shape.getGraphicsAlgorithm().getGraphicsAlgorithmChildren().clear();

			// set background color
			ShapeStyle shapeStyle = new ShapeStyle();
			shapeStyle.setDefaultColors(PROCESSENTITY_BACKGROUND);

			// add the blank image into the upper left corner....
			Image imga = loadCustomTaskIcon("my-blank-image.png", shape.getGraphicsAlgorithm());
			Graphiti.getGaService().setLocationAndSize(imga, 2, 2, 24, 24);

But I can not see why this should be necessary..... strange.

Note: these are two different things - the one is the image defined in your plugin definition which is also affecting the palette. The other one it your shape layout method where you define what happens in the design panel.

I tried this, but I got the error "The method loadCustomTaskIcon(String, GraphicsAlgorithm) is undefined for the type new AddTextAnnotationFeature(){}"
I'm not working with a task...

This is how you can load the image:

		String imageId = fileName;
		String filename = "/icons/large/" + fileName;
		URL url = getClass().getClassLoader().getResource(filename);
		ImageDescriptor descriptor = ImageDescriptor.createFromURL(url);

		CustomTaskImageProvider.registerImage(imageId, descriptor);
		Image img = Graphiti.getGaService().createImage(ga, imageId);
		img.setProportional(false);
		img.setWidth(16);
		img.setHeight(16);
		img.setStretchH(true);
		img.setStretchV(true);

Some news :
I can now add my image. I know it because when I drag my extension from the palette, orange dots which permits to resize the image are visible. But the rectangle shape is not visible anymore.
If I click on the feature, I select the blank icon.
Then, I think the rectangle (and maybe the previous icon ?) is "covered" by the blank icon.
