    There used to be ColumnSelectionModel for grids in 3.0. It's not around anymore. So how can I create grids with checkboxes?

    You have to use the selModel "Ext.selection.CheckboxModel", ie:
    Code:
    var gridPostausgangSM = Ext.create ('Ext.selection.CheckboxModel',
    {
        mode: 'MULTI'
    }
    See the docs for details

    I resolved my problem,

    but it should be useful to know that for an Ext.form.field.TextArea the old expression :
    Code:
    this.getEl().dom
    is not equivalent in extjs4, I had to use now:
    Code:
    this.inputEl.dom

    FYI, the compat layer files were updated and a new zip file posted earlier today (download). There was one fix for a breaking change due to an internal 4.0.1 change that affected a grid override, but most everything else is just additional aliases that did not exist before and a few other minor fixes.

    If you aren't having any major issues with the original compat files then there's not much need to upgrade, but if you're just starting or having issues you should try the newest version.

    Default Auto height

    Auto height


    Thanks for answering my question, DHainzl. Here is another one. There is no autoHeight attribute for panels any more. Is auto height still supported? If it is what is the substitute for it?

    Are all these details described anywhere other than this forum and a very short migration guide?

    Sorry vlads, I can't help you with this question, because I have never used autoHeight myself ...

    But I have another question:
    I have a tree panel and I want to change the class of the nodes.

    In ExtJS 3 I could do this:
    Code:
        var ui = node.getUI();
        if (nodeEdited[node.id] > fieldValue)
        {
            ui.addClass ('treenode-changed');
        }
        else
        {
            ui.removeClass ('treenode-changed');
        }
    but in ExtJS 4.0.0 I now have a NodeInterface-Object. This:

    Code:
        if (nodeEdited[node.data.id] > fieldValue)
        {
            node.set('cls', 'treenode-changed');
        }
        else
        {
            node.set('cls', '');
        }
    doesn't work.

    Thanks in advance for the help!

    Dave

    The TreeGrid does not seem to be compatible with the Ext.grid.PagingScroller. There is an error in getSizeCalculation (ext-debug : 73869):

    Code:
    height = store.getTotalCount() * this.rowHeight;
    The TreeStore does not have a total count method. Will these two features be compatible in the future?

    I have Ext3 code that uses store.fields to automatically build a grid filter. What is the proper way to get the field definitions from a store in Ext4?

    Default Tab panels with same id's?

    Tab panels with same id's?


    In ExtJs3.x I had a button which added a panel to a tabpanel. This panel had an id, so when I clicked this button the panel was only added to the tab panel if a panel with that id did not already exist.
    This does not seem to be the case in ExtJs4.
    (i.e. I can add multiple panels with the same id to a tabpanel in ExtJs4. )
    Has this behavior changed?
    If so, how can I replicate the behavior of the tab panel in ExtJs3.x?
