Gelmiş geçmiş en büyük porno sitemiz olan 2pe de her zaman en kaliteli pornoları sunmayı hedefledik. Diğer video sitemiz olan vuam da ise hd porno ağırlıklı çalışmalara başladık.

    Thank you for reporting this bug. We will make it our priority to review this report.

    Default [FIXED] Selected Tree Item not Shown as Selected After Reordering the Tree Item

    [FIXED] Selected Tree Item not Shown as Selected After Reordering the Tree Item


    Regarding to this demo (http://extjs.com/examples-dev/explor...reorderingtree), the selected item is not shown as selected after reordering the tree item. Actually, by calling tree.getSelectionModel().getSelectedItem(), it returns non-null model.
    (I have tested in firefox, chrome and IE8)

    The previously selected item was not cleared on remove. Fixed in RC1.

    The moving item is unselected when I drop it down. Should I select the dropped item again? If so, how can I get the previous selected item since I got null when I call tree.getSelectionModel().getSelectedItem() in the dragDrop() method of TreePanelDragTarget DNDListener.

    You could store the selection before startign the drag (for example in a listener) and restore it on a drop.

    Yes, I can select in this way. But, visually, it is not selected. It remains white in color.
    Below is my code:

    Code:
    		TreePanelDragSource source = new TreePanelDragSource(menuTreePanel);
    		source.addDNDListener(new DNDListener() {
    
    			ModelData sel;
    
    			@Override
    			public void dragStart(DNDEvent e) {
    				sel = ((TreePanel) e.getComponent()).getSelectionModel()
    						.getSelectedItem();
    				if (sel != null
    						&& sel == ((TreePanel) e.getComponent()).getStore()
    								.getRootItems().get(0)) {
    					e.setCancelled(true);
    					e.getStatus().setStatus(false);
    					return;
    				}
    				super.dragStart(e);
    			}
    
    			@Override
    			public void dragDrop(DNDEvent e) {
    				((TreePanel) e.getComponent()).getSelectionModel().select(
    						false, sel);
    				super.dragDrop(e);
    			}
    
    		});

    You have to to this after the dropping is done. Currently you select it before it.
