Deselect ListItem on Tap?

[BenMajor]

Sorry, it's me again. It's been a long day today and I'm tired so perhaps I missed it, but I can't get the items in a List to deselect when showing an ActionSheet.

Essentially, I want the list to display an ActionSheet when the user taps an item. I've got all of this working without problem, but for I can't figure out to remove the selected class once the ActionSheet has been displayed. Here's a screenshot of the situation at the moment:



As you can see, the item is still selected underneath the overlay. Any idea how I can prevent it from remaining selected?

Thanks,
Ben.

You could call the deselect method of the Ext.List class when you show the action sheet passing in the output of the getSelectedRecords method?

Thanks Stoot, this is the solution I have at the moment, but just wondered if there was a parameter built into the List constructor?

Regards,
Ben.

Back again, and still not able to solve the problem here - sorry to be such a pain.

Here's the function I have bound to the itemTap event:

itemTap: function(list, index)
{
    // Deselect the selected record:
    var currentRecord = list.getStore().getAt(index);
    currentRecord.forename      = currentRecord.get('forename');
    currentRecord.surname       = currentRecord.get('surname');
    currentRecord.phoneNumber   = currentRecord.get('phoneNumber');
    currentRecord.shortFullName = currentRecord.forename + ' ' +  currentRecord.surname[0];

    list.getStore().deselect(index, true);

    callButton.setText('Call ' + currentRecord.shortFullName + ' (' + currentRecord.phoneNumber + ')');
    unfriendButton.setText('Remove ' + currentRecord.shortFullName + ' as friend');
    friendActionSheet.show();
}

However, this seems to return the error:

Object [object Object] has no method 'deselect'

. Can anyone shed any light on the matter?

Thanks,
Ben.

I think the deselect method is a method of the List rather than the store.

[BenMajor]

Thanks for the quick reply, that seems to have prevented the error from occurring, but no deselect occurs. Am I using the method correctly?

list.deselect(list.getStore().getAt(index), true);

It seems that calling list.refresh() removes the highlighting, but also prevents the item from appearing in the 'x-view-selected' completely, which I don't think is good for HCI (there's no feedback to the user as to which list item was tapped.

I noticed that if I remove the showing of the ActionSheet, the list item remains selected unless I tap another item, in which case the latter is given the blue 'selected' class. Surely there must be away to deselect the current list item in Sencha, since the built-in methods of the ListView seem to achieve it? Any help?

Thanks,
Ben.

This is how i do it on my lists:

listeners: {
	itemtap: function(dv, ix, item, e) {
		// Delay the selection clear
		// so they get a nice blue flash for HCI's sake
		setTimeout(function(){dv.deselect(ix);},500);
	}
}

Hi Chris,

That was fantastic and did the job precisely. Thanks for your help!

Best regards,
Ben.

In Sencha Touch 2, we can add a config while creating a list as disableSelection: true

Ext.define('App.view.NewsList',{    
    extend: 'Ext.List',
    xtype: NEWS_LIST,
    
    config: {
        store: NEWS_FEED,
        //deselectOnContainerClick: true,// not working in Sencha Touch 2
        disableSelection: true, // since Sencha Touch 2
        itemTpl: '{heading}'
    } 
});
