How to load and display an image on selection of a Node in TreeViewer in eclipse e4 rcp?

I am trying to load an image from a user selected input file and show it to the user using a Label. This image is a property of the selected TreeViewer node. So when selection changes the image (if exists) should be changed as well. (Master/Detail scenario)

The forum post How to load image to view in RCP? suggests that I have to manually read the image as a byte array.

Is there framework provided way to load and display images directly? Also if such a way exists what do I have to do to replace the image with a new one when selection changes? so that there is only one image in memory at a time.

Solution

  • To read an image use: 

    ImageDescriptor desc = ImageDescriptor.createFromFile(null, "file path");

Image image = desc.createImage();

    don't forget the dispose of the image when you are done with it.
