Hello

I would like to display an error icon above a grid panel and automatically show its tip without waiting for mouseover event. I managed to create and display the error icon but I can't show its tip.
Here's my code:

Code:
        t = contactGrid.getEl().createChild({ cls:'x-form-invalid-icon', id:'invalidGridIcon' });
        t.dom.qtip = "You must select at least one contact!!";
        t.dom.qclass = 'x-form-invalid-tip';
        t.show();
        t.alignTo(contactGrid.getEl(), 'tl-tl', [2, -20]);
As I said, this code correctly shows and aligns the icon above the grid. However the tip is not shown unless I move the mouse over the icon...is there a way to show the tip as soon as the error icon gets visible?
Thanks in advance
Dario
