GtPhlowView empty columnedTree
	items: [ 1 to: 10 ];
	children: [ :e | #() ];
	column: 'Data' text: [ :e | e ];
	contextItemLabel: 'Test 1'
		action:  [ :anElement :anItem |  ]
		if: [:anItem |  true ];
	contextItemLabel: 'Test 2'
		action:  [ :anElement :anItem |  ]
		if: [:anItem |  true ];
	contextItemLabel: 'Test 3'
		action:  [ :anElement :anItem |  ]
		if: [:anItem |  true ];
	contextItemLabel: 'Test 4'
		action:  [ :anElement :anItem |  ]
		if: [:anItem |  true ]
