Bug 229841 Widget is disposed in ControlExample
- run the ControlExample - press the Set/Get API Button --> shows a dialog - press this button again --> shows another dialog - close the second of these dialogs - in the first dialog choose anything in the Combo and you'll get the error at the bottom -> the problem is that Tab.resetLabels() is sending #getText() to the Text that was on the second of the dialogs; this happens because the two shown dialogs were sharing Tab's fields like setText, get/setButton, etc. Exception in thread "main" org.eclipse.swt.SWTException: Widget is disposed at org.eclipse.swt.SWT.error(SWT.java:3773) at org.eclipse.swt.SWT.error(SWT.java:3691) at org.eclipse.swt.SWT.error(SWT.java:3662) at org.eclipse.swt.widgets.Widget.error(Widget.java:462) at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:335) at org.eclipse.swt.widgets.Combo.getText(Combo.java:838) at org.eclipse.swt.examples.controlexample.Tab.resetLabels(Tab.java:1018) at org.eclipse.swt.examples.controlexample.Tab$35.widgetSelected(Tab.java:982) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:227) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1002) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3782) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3381) at org.eclipse.swt.examples.controlexample.ControlExample.main(ControlExample.java:210)
