Alexander,
Thank you, but I was looking for a simpler method of storing child
widgets (I mean simpler then private class members). But now I have to
patch the Modern theme (using qx.Theme.patch) or instantiate it just to
define the aliases... (since those cotrols I'm refering using ID are
simple qooxdoo widgets, like selectbox, button etc...). Btw, I tried
another hack:
_createChildControlImpl: function(id) {
var control = null;
switch(id) {
case 'mainpane':
var control = new qx.ui.splitpane.Pane('vertical');
control.setAppearance('splitpane'); # <- this is hack:)
this.add(control, {edge: 0});
break;
case 'topframe':
var control = new qx.ui.embed.Iframe();
this._getChildControl('mainpane').add(control, 3);
break;
case 'finderpane':
var control = new dbgui.ui.splitpane.Pane();
this._getChildControl('mainpane').add(control, 2);
break;
case 'finder':
var control = new dbgui.ui.finder.Box();
this._getChildControl('finderpane').add(control);
break;
}
setting appearance just after widget is created, but that didn't help
(still getting those annoying messages). So the only way of using this
sweet feature is to define appropriate aliases/appearances, correct?
Thanks,
Oleksiy
