问题 In ExtJS 4.0.2a I could change the cursor image over a grid using: body.setStyle('cursor','move'); This doesn't seem to work in 4.0.7 or 4.1. I don't get any css error but it does give an unnatural lag at the point where the change should occur. Maybe it gets overridden? UPDATE: I am trying to run this from a grid onitemmousedown event. I found that the GridView gets a class ".x-unselectable" to make grid text unselectable (which I want). However in ExtJS 4.0.7 and 4.1 this ".x-unselectable"

问题 I'm trying to add Ext4 charting to an existing Ext3 application, using ext-all-sandbox.js. I've got the basics working, but the code below gives axis.processView is not a function . It works fine without the axes defined (but with no axes obviously). It appears that the config objects are being used directly instead of being used to create actual axis instances. Any solutions to get this working? TestGraphPanel = Ext.extend(Ext.Panel, { initComponent: function() { TestGraphPanel.superclass

问题 I have a grid with row-editing enabled. When I add a row and call store.sync(), the server generates certain fields on that record, and returns the full record info in the response. However, ExtJS does not seem to update its copy of the record, except for the id. Is there a way to make it do that, or do I need to write custom code? This is an excerpt of the grid's controller: doneEdit: function (editor, e, eOpts) { var me = this; // // Set up loading mask on grid during update (if record
