I created bug #3314 and attached a patch. The patch makes the focus
indicator instantiation customizable like most other internal-use classes.
Please apply the patch and ensure that things still work exactly as they do
currently.
Once you've confirmed existing behavior, you can then create a new, small
class, something like this untested snippet, to do what you require:
qx.Class.define("custom.FocusIndicator",
{
extend : qx.ui.table.pane.FocusIndicator,
events :
{
"focusChanged" : "qx.event.type.Data"
},
moveToCell : function(col, row)
{
this.base(arguments, col, row);
this.fireDataEvent("focusChanged", { col : col, row : row });
}
});
Then when you instantiate your table, you pass a newFocusIndicator member in
the 'custom' parameter:
var newFocusIndicator = function(obj)
{
return new qx.ui.table.pane.FocusIndicator(scroller);
};
var table = new qx.ui.table.Table(tableModel, newFocusIndicator);
With that, you should get a "focusChanged" event whenever the focus changes
for any reason.
Hope that works and helps. Please confirm, and I'll apply the patch to
trunk.
