    I assume the change you suggested was to put (autoScroll: true) in the Ext.create call. I did that with no change in behavior. I can scroll through the grid using the mouse scroll wheel, but there is...

    Stevil,

    Thank you for your response. Your suggestion did not work. As soon as I did what you suggested, the scrollbar disappeared altogether (in FF). Here is teh new code:

    The Ext JS 4 application that displays a single set of scroll bars in the grid control in FF and Chrome displays two sets of scroll bars in IE 9 (see attached image). I had to set autoScroll=true on...
  4. Hello,

    I have an ExtJS 4 app working well in Firefox and Chrome browsers. I am experiencing a number of issues in IE 9. One of them deals with rendering of check boxes. The attached image shows...

    I would like to display a tooltip each time a mouse enters the text for the tree node and hide it as the mouse exit the node's text. What is the proper way of doing that in Ext JS 4?

    Thank you,

  7. I dug deeper into this issue (apparently nobody else has encountered it). My problem appears to stem from the changes in Ext JS CSS related to checkboxes:

    This style (ext-all-debug.css, line 3931)...
  8. The code that worked fine in all prior Ext JS 4 releases no longer works.

    The checkboxes do not work: they appear unchecked and you cannot check them. Besides, the boxes and labels are slightly...

    I am trying to handle a 'checkchange' event in the TreePanel. It is gone from the Beta 2 documentation. So did all TreeNode classes. How do I detect when tree nodes get checked/unchecked?

    Tried that - no success. When I stepped through the code, I discovered that load data expects the tree to have a model, which mine does not. Ext JS 4 PR 5 has an example of a tree with a model, but...

    All the tree-related examples assume that JSON comes from a URL. How do I load the tree from a JSON object that is available in my program? I tried creating a TreeStore with MemoryProxy, and loading...
  14. You are correct, Evan, but this is just a typo in my post (I modified the code manually to reproduce my original code). If you correct the mismatch of the store ids, you will get the error I...

    http://dev.sencha.com/deploy/ext-4.0-pr4/docs/api/Ext.data.XmlReader.html is missing.

    XmlTreeLoader class is not part of ExtJS 4 code base. Are there plans to migrate Ext.ux.tree.XmlTreeLoader from version 3 to 4? How incompatible is the class from ExtJS 3?

    Thank you,

  19. ExtJS 3 introduced a 'ref' attribute allowing the code to refer to the child components (nested at any level) of a given component using simple dot notation.

    Hello,

    The designer allows me to convert a UI component into separate JS class. I am trying to figure out how to reuse that class. In my UI, I need the same set of checkboxes (representing a set...
