Question

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?

Answer 1

You can just use:

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

Or use Display.getCurrent() instead.
