ActionItem visibility

Hi,

 

I've been trying to dynamically hide/unhide an ActionItem but the 'visible' property doesnot exist for ActionItem...only 'enable' exists which simply grays out the item. 

 

Has anyone been able to hide/unhide action items?

 

It's a common UI usage on older BB devices to only display meaninful context menus when you select an item in a list for example:

if currently selected item has an address, show the MAPS menu (action item)

but if no address exists, do not show the MAPS menu (action item) as it is useless

 

thanks,

Re: ActionItem visibility

Hi there,

 

Have you tried removingthe actionItem conditionally instead?

Re: ActionItem visibility

removing / adding from QML doesnt work yet

 

ActionItems and Tabs don't have a property visible - only enable true/false

(and enable false only dimms the icon not the text)

 

there are Issues reported by me in IssueTracker - please vote

BBTEN-252 and BBTEN-251
