问题 In an ExtJS 4.1 grid that uses CheckboxModel as a selection model, when you click on an entire row, that row is selected (and the corresponding checkbox is checked). Is there a way that I can prevent that default behaviour from happening and permit row selection only when the checkbox for a corresponding row is clicked (as opposed to when clicking the entire row)? Again I'm using ExtJS version 4.1 Thanks for any help Note: My grid also has the CellEditing plugin attached to it. I don't want

Here is my tree's config, what am I doing wrong? todotree = { title: 'Tree Grid', width: 600, height: 400, viewConfig: { plugins: { ptype:

问题 I am developing an app using Sencha Touch 1.1.1. I would like to create an item on a form similar to the iPhone ringtone field (see image). Currently I'm using a textfield and when it gets focus I'm changing the card to a list. The only problem with this is the on-screen keyboard is displayed. How can I create a form field like the Ringtone field in the iOS sound configuration? 回答1: I have a solution for now. I created a new class - ListField - based on the code for the Selectfield. I would
