Question

I have an adobe flex datagrid with a simple custom label itemrenderer in one of the columns. Clicking on the itemrenderer fires off a cairngorm event, which results in a service call being made, and the data from the service call populates a TitleWindow.

Even though I have set the doubleClickedEnabled property to false, its still possible to sometimes double click the item renderer, resulting in two service calls being made, and two TitleWindows being shown. In other cases, triple clicking seems to trigger the undesired result as well.

Is there any method to prevent this kind of behaviour?

Answer 1

Keep track of when you get a click event and if you get two within a certain amount of time (250ms) ignore the second.

var lastTime:Date = new Date(0);

function OnClickHandler(event:Event):void {
    if ((new Date()).time - lastTime.time < 250) {
        return;
    }
    lastTime = new Date();
    ...
}
