Hi all,
is there any example code showing how to use this?
I have a simple tableview that would like to have a popup in each row.
I have added NSPopUpButtonCell to the relevant column.
Ive created an instance of NSMenu
I have set the 'menu' outlet of the NSPopUpButtonCell column to this
menu.
I have set the 'delegate' outlet of the NSMenu to a controller.
I have implemented - (void)menuNeedsUpdate:(NSMenu *)menu in this
controller
Another, separate, NSPopupButton uses this with no problems whenever
it is clicked on.
The problem I have is that the NSPopUpButtonCell never actually calls
menuNeedsUpdate on its delegate.
Is this a known bug? have I skipped a step?
What is the menuNeedsUpdate: method supposed to do? I can't find it in
the documentation. Is it your action method for the menu?
If anyone knows of some sample code showing this working I would love
to see it.
If the idea is to know when a new menu item has been selected and
reflecting this change to the popupbutton cell in the table, IIRC, here
is how you can proceed:
- select the proper menu item in the
-tableView:willDisplayCell:forTableColumn:row:; method.
- get the selected item index in the -
tableView:setObjectValue:forTableColumn:row: method.
