Bug 459643

Description Sebastian Eckey 2015-02-11 06:20:04 EST

When setting a selection on a Combo(Viewer) programmatically, in RAP the text of a combo is highlighted. It looks like as if the Combo has the Focus (the Background turns blue) but in fact the Combo does not have the Focus.

Pressing space or enter triggers the button(see snippet), pressing a letter enters the value into the combo(viewer).

Running in SWT the combo(viewer) does not get highlighted, pressing a letter does not enter the value into the combo(viewer). This is the behavior I would expect.

Bug was already reported and fixed in 1.3 (Bug 289398).
Bug can be reproduced in 2.3.1 and 3.0.0-M5
Reproducible: Always

Snippet to run:
private class TestComposite extends Composite {
 public TestComposite(final Composite parent) {
  super(parent, SWT.NONE);
  setLayout(new GridLayout(4, false));

  final Combo combo = new Combo(this, SWT.NONE);
  final Text text = new Text(this, SWT.BORDER);

  final Combo combo2 = new Combo(this, SWT.NONE);
  final Text text2 = new Text(this, SWT.BORDER);

  final Button button = new Button(this, SWT.PUSH);

  combo.setItems(new String[] { "Car", "House", "Tree", "Shoe" });
  combo2.setItems(new String[] { "Car", "House", "Tree", "Shoe" });

  combo.select(new Random().nextInt(4));
  combo2.select(new Random().nextInt(4));

  button.setText("Switch Selection");
  button.addSelectionListener(new SelectionAdapter() {		
    @Override
    public void widgetSelected(SelectionEvent e) {
     int index = combo.getSelectionIndex();

     combo2.select(index < 3 ? index + 1 : index - 3);
     combo.select(index < 3 ? index + 1 : index - 3);
     text.setText(combo.getText());
     text2.setText(combo.getText());
   }
  });
 }
}
