Here’s a quick example of how to use a Sencha ExtJS or Touch DelayedTask:
onMainViewportAfterRender: function(viewport, options) { var tabPanel = viewport.down('tabpanel'); var task = new Ext.util.DelayedTask(function() { tabPanel.setActiveTab(0); }); task.delay(250); }
As shown, the first thing you do is create a task
by giving a DelayedTask
a callback function. Then you tell the task
how long it should delay before executing.
There are better reasons to do this than what I’ve shown, but (a) this is a simple example, and (b) I have been having a hard time trying to set the active tab, and as a quickie bug fix for the moment, this works.
Note that you can also do this with plain old JavaScript and setTimeout
, like this:
setTimeout(myFunction, 250);
