That's an interesting and easy solution. To solve your problem, you can
probably do something like the following:
Subclass qx.ui.table.pane.FocusIndicator and override the constructor and
moveToCell method:
construct : function(scroller)
{
this.base(arguments, scroller);
this.__scroller = scroller;
}
moveToCell : function(col, row)
{
this.base(arguments, col, row);
// Get the table model and the data in the cell
var tableModel = this.__scroller.getTable().getTableModel();
// Retrieve the data for the focused cell
var data = tableModel.getValue(col, row);
// Use this data somehow in this focus indicator
}
Then to be able to use this custom focus indicator, you'll have to override
the scroller as well so that the focus indicator child uses your new class:
_createChildControlImpl : function(id)
{
var control;
switch(id)
{
case "focus-indicator":
control = new custom.FocusIndicator(this); // THIS IS YOUR FOCUS
INDICATOR SUBCLASS
control.setUserBounds(0, 0, 0, 0);
control.setZIndex(1000);
control.addListener("mouseup", this._onMouseupFocusIndicator, this);
this.getPaneClipper().add(control);
control.show(); // must be active for editor to operate
control.setDecorator(null); // it can be initially invisible, though.
break;
}
return control || this.base(arguments, id);
}
and then arrange to use the new scroller:
var custom =
{
tablePaneScroller : function(obj)
{
return new custom.Scroller; // THIS IS YOUR SCROLLER SUBCLASS
}
}
var table = new qx.ui.table.Table(tableModel, custom);
That "should" do it for you.
