EclipseRCP 체크박스에서 재귀선택 이벤트 (EclipseRCP recursive selection event in checkbox viewer)

It’s Tips for CheckboxViewer.

I found bug that throw selection event three times in CheckboxViewer(CheckboxTreeViewer,CheckboxTableViewer).

This bug appear when user click checkbox on selected object.

Then I disable selection as well as “viewer.setSelection(null);";

And I need the checkbox behave likes the radio button.

I implemented it through history clear.

Code:

boolean isHistory;
Object currentObject;
public void selectionChanged(SelectionChangedEvent event) {
if(isHistory) {
isHistory = false;
return;
}
if (!event.getSelection().isEmpty()) {
	if (event.getSelection() instanceof IStructuredSelection) {
	if(currentObject!= null) {
	if(! currentObject.equals((IStructuredSelection)event.getSelection()).getFirstElement())) {
	isHistory = true;
	viewer.setChecked(currentObject, false);
	viewer.setSelection(new StructuredSelection(currentObject);
	isHistory = false;
	viewer.setSelection(null);
	}
	}
	currentObject = (IStructuredSelection)event.getSelection()).getFirstElement();
	viewer.setChecked(currentObject , !viewer.getChecked(currentObject ));
	viewer.getTable().setSelection(currentObject.index);
	viewer.setSelection(null);
	}
	}
	}
