SWT - Adding a Image to a Button in a table - tableViewer

I would like to add a image to a button in my table. The table is displayed in my main GUI. I am using a TableViewer to display the table.

private void createTableViewer(Composite parent) {

  viewer = new AplotDataTableViewer(parent, SWT.BORDER|SWT.V_SCROLL|SWT.FULL_SELECTION);
  viewer.setInput(AplotDataModel.getInstance().getArrayData());

}

AplotDataTableViewer is a separate class. The constructor for AplotDataTableViewer takes in the composite and Style.

So when I try to add a image in the AplotDataTableViewer class, it gives me a error on the Display variable. I think it is because Image requires a Display.

Image image = new Image(display, String);

I am not sure what it is needing for display? If it is needing the display from the main GUI, how do I get that?

I am not sure what error you are getting. I am guessing it might be "Invalid Thread access" as you are accessing UI objects from non-UI thread.

You can create images by referring to the link given by Baz. If your plugin has Activator, just check for public static ImageDescriptor getImageDescriptor(String path) here path starts with ex: /icons/image.png. User ImageDescriptor.createImage(true) will give the actual image that you are looking for. Keep track of the images in a cache before creating new one from imagedescriptor.

Setting Image on Button, check for documentation. Few platforms won't support setting both image and text.

You can just use:

Image image = new Image(Display.getDefault(), "path/to/image.png");

Or use Display.getCurrent() instead.

For more details, here is a good tutorial about SWT Images:
