validatemenuitem

Scripting Forums AppleScriptObjC and Xcode

How do you script the following objective-c code in ASOC:

I have searched this list high and low and can find no reference to validatemenuitem.

Is nobody using menus in their apps?:slight_smile:

- (BOOL)validateMenuItem:(NSMenuItem *)item
{
	if (([item action] == @selector(newLibrary:) || [item action] == @selector(openLibrary:)) && [libraryData isLibraryOpen])
	{
		return NO;
	}
	if ([item action] == @selector(addFolderToLibrary:))
	{
		return [libraryData isLibraryOpen];
	}
	if ([item action] == @selector(closeLibrary:))
	{
		return[libraryData isLibraryOpen];
	}
	if ([item action] == @selector(toggleColorAdjDrawer:))
	{
		return[libraryData isLibraryOpen];
	}
	return YES;
}

All the best

validateMenuItem: is deprecated; you’re supposed to use validateUserInterfaceItem: instead. At a guess, you would use something like:

on validateUserInterfaceItem_(anItem)
set theSel to anItem's |action|() as text
if theSel = "addFolderToLibrary:" then
return true
else...

Hi Shane,

It appears is is only deprecated on NSDocument.

Please read this thread:

http://www.cocoabuilder.com/archive/cocoa/207076-validatemenuitem-not-always-being-called.html#207076

I am in the process of trying your suggestion and will report back.

Thanks

Hi Shane,

I can confirm that both work:

	on validateUserInterfaceItem_(tMenuItem)
		
		set tSel to tMenuItem's |action|() as text
		
		if (tSel = "newAccount:") and (pAccountOpen = true) then
			return false
		end if
		
		return true
	end validateUserInterfaceItem_

or

	on validateMenuItem_(tMenuItem)
		
		set tSel to tMenuItem's |action|() as text
		
		if (tSel = "newAccount:") and (pAccountOpen = true) then
			return false
		end if
		
		return true
	end validateUserInterfaceItem_

Hope this helps.

All the best

Out of interest, where I was going wrong was not putting the pipes around action.

It’s disappointing that ASOC can’t recognise what you are doing and put the pipes around key words for you.

A little more info from the Apple docs with XCode:

It’s just using standard AS parsing, o there’s not a lot that can be done.
