Question

let’s say we have 10 checkboxes, How would you make after you choose One, other checkbox is non editable or selectable for example

If we choose checkbox A, the checkbox -A must be non editable or selectable.

Is this possible?

Answer 1

Yes, apply a SelectionListener to your Control and Disable all other Controls with a loop through all your controls.

b1.addSelectionListener(new SelectionAdapter() {
  public void widgetSelected(SelectionEvent e) {
     for(Control child : composite.getChildren()){
        if(child != b1) {
           child.setEnable(false);
        }
     }
  }
});
