PROP_VALUE>
onFocusGained
protected void onFocusGained()Upon focus gained, the selection of an entry field is selected fully and for a combobox, cursor is placed first.onFocusLost
protected void onFocusLost()Called when focus is lost. The control can set the selection to the beginning of the field to show the text.setToolTipText
