Ext tree grid event conflict
Here, I made a treegrid refered to this example,http://docs.sencha.com/extjs/4.2.0/extjs-build/examples/build/KitchenSink/ext-theme-neptune/#tree-grid .
The difference is that I add a itemclick listener to the tree leftside in my app,and a handler to the last column (which xtype is actioncolumn as the example showed) .
Here comes the question. When I click the icon in the last actioncolumn ,it not only fire the column action event but also the tree itemclick event. So how to solve this problem? I try to use "event.stopEvent()" and "event.stopPropagation()" functions ,but failed. So help me, thanks.

Return false from the event handler.

Return false from the event handler.

well just like the stopEvent() and stopPropagation() functions in the handler ,return false doesn't make any sense.:(

well today I add a if statement to the itemclick event ,and the question resolved.Here is the core code:

treeObj.addListener('itemclick', function(node, record, item, index, event, eOpts){ //get the grid cellIndex you clicked var colIdx = event.getTarget('.x-grid-cell').cellIndex; //compare the cellIndex with the cellIndex of your tree exist if(colIdx == 0){ //your core code }}
