  1. Ah! Silly me... "pro" == "protected" and callParent()/callOverridden() were hidden because the doc filters were set to not show protected items. Derp.
  2. I just did a search in the API docs site for callParent() and callOverridden() and have a couple of questions:

    1. They show up in the search results with a "pro" label next to them--what does that...

    You can configure your column to use a renderer that, in addition to returning the value shown in the cell, can modify the <td> element surrounding the cell. Specifically, you can add the "data-qtip"...
  4. Does anyone have an actual example of how to do this with ExtJS 4? I've tied extending the column class and adding a ProgressBar as a child item, but it doesn't work.

    Thanks!
  5. In case anyone else comes across this in the future, note that the issue seems to be that ExtJS 4.0.x uses custom scrollbars--something that's been discontinued in 4.1 (i.e., 4.1 uses native scroll...
  6. I have a tree panel and am trying to do an animated scroll to certain locations. I'm using myTreePanel.getView().getEl().scrollTo('top', yCoord, true) to do this.

    The view does scroll down to the...
  7. I have an Ext.grid.Panel (aka gridpanel) with a store, used only for "visual effect" (i.e., nothing gets saved to the server). When I create new model instances and add them to the store they are...
  8. msims to the rescue (again)--thanks!
  9. Hi. I have a grid panel which uses a RowEditing plugin configured as follows:

    var rowEditing = Ext.create('Ext.grid.plugin.RowEditing', {
    clicksToMoveEditor: 1
    });

    rowEditing.on('edit',...

    I'm not sure if this is relevant, but if you look at the source for Connection.request you'll see that it only tries to use a cross-domain request for IE 8+:

    if ((options.cors === true || me.cors...
  11. Found a solution (although still open to hearing other ideas).

    First, you can call a store's load() function with a config object that will be passed to an operation. The API docs for...
  12. For example, say I have a server API for loading people that handles requests like this: GET /people/?id=101,329,27

    I'd like to build a Store (probably a custom class that extends Ext.data.Store)...
  13. Solution: use layout=auto instead of vbox. If anyone is curious:

    Thanks to tvanzoelen for...
  14. I have a form panel with autoScroll=true, but the scrollbars aren't showing up. There's a working example of it here that anyone can fork and modify: http://jsfiddle.net/clint_harris/Bt6w9/ (also,...
  15. I've been told by one of the Sencha developers that there's a ticket in Jira (EXTJSIV-28) for adding filtering to tree, scheduled for 4.1.
  16. I'm using KeyMap to intercept Alt+F keyboard events. In IE8, I'm unable to prevent the event from propagating and causing the browser's File menu to be shown.

    Runnable test case:...
  17. Here's the solution that I'm using (again, you can actually try running/modifying it here: http://jsfiddle.net/clint_harris/Syhj2/):

    Ext.define('MyMenuItem', { extend : 'Ext.menu.Item',
    ...
  18. Thanks! Funny, I was just trying the same thing. It does work--I have a working example here: http://jsfiddle.net/clint_harris/Syhj2/ (a few cosmetic kinks to work out, but functional)
  19. I'd like to make a menu (i.e., Ext.menu.Menu) where the items include a right-aligned keyboard shortcut--something like this:

    29189

    I can't find an obvious/out-of-box way to do this with...
  20. For anyone else who comes across this, the work-around I think Mitchell is suggesting involves setting the reader similar to as follows (i.e., using setReader() in the constructor instead of defining...
  21. Hey Mitchell, thanks for taking a look at this.

    To be clear, I only see this problem if "ModelA" is defined before "ModelB". When I reload my application, sometimes ModelB is defined first; in...
  22. Note that a temporary work-around I've found is to hard-code the proxy config portion of each model class with the model class name. For example:


    Ext.define('MyAModel', {
    extend:...
  23. I believe the following scenario reveals a bug:
    Define a model class, ModelA, with a proxy config
    Define another model class, ModelB, also with a proxy config
    Call ModelB.load(...)
    Issue: The...
  24. That works! I don't know how--all the other functions I tried on the component and/or element regarding width didn't work--but I'll take it! Thanks!
  25. What's the best way to get a floating component to "shrink" to the width of its contents (a single line of text) and center horizontally?

    What I'm doing now is *not* specifying a width for the...
