nstokenfield

Is it possible to get an event when you click on a token in a NSTokenField? Seeing as those tokens ( NSTokenFieldCell s) inherit from the NSCell class, in theory, yes, you can have them send an event by giving them an action and a target ( -setAction: and -setTarget: respectively, and if you want to give the tokens menus when pressed, use -setMenu: ). 来源： https://stackoverflow.com/questions/4588599/clicking-token-in-nstokenfield

I was looking at NSTokenField, NSTextField and NSTextView with no luck to do the following: I am writing a Twtitter client and when you want to twitter a new Tweet then you begin to write in a text field for example: Going to make coffee, @pe When you begin to write a @ then I would like to help the user to autocomplete the username for example @peter . I have a NSArray with the usernames like: NSArray *usernames = [NSArray arrayWithObjects:@"@andreas", @"@clara", @"@jeena", @"@peter"] What should I do to enable a simple autocompletation? I'd be happy if you would have to press F5 or something

I need implement Command + Enter, Command + O and Esc shotcuts for NSTokenField and solutonns like https://stackoverflow.com/a/18486965/1067147 not worked because -(void)noop:(SEL)sel isn't useful. My way is to create category for upper-in-hierarchy class NSView (also I try it for NSTextView but no luck): // NSView+WideInterpreter.h #import <Cocoa/Cocoa.h> #define kNotificationTokenModifier @"kNotificationTokenModifier" #define kNotificationTokenModifier_modifier @"kNotificationTokenModifier_modifier" typedef enum{ BMTokenModifier_CommandEnter = 10, BMTokenModifier_CommandO, BMTokenModifier

My issue is that NSTokenField does not allow me to type any text I want, it's only allow me to type strings that are included in the NSArray that tokenField:completionsForSubstring:indexOfToken:indexOfSelectedItem: returns. - (NSArray *)tokenField:(NSTokenField *)tokenField completionsForSubstring:(NSString *)substring indexOfToken:(NSInteger)tokenIndex indexOfSelectedItem:(NSInteger *)selectedIndex { return [NSArray arrayWithObjects:@"AA", @"BB", @"CC", @"DD", nil]; } My NSTokenField can only contain the above text-tokens. If I type for example XXX it does not appeared and it cannot be added.

When entering an invalid email in Mail's NSTokenField one get's this (a mix of token and plain string values ): Is there any recommendable way to accomplish this? Is NSTokenField even the right tool for this? Or would I be abusing it? In this particular project I need to allow the user to enter a file name pattern (there are several other use cases though) , with support for predefined tokens. Right now I'm requiring the input to be entered like this: Glue Text %[Tag]Other Glue Text%[Another Tag]More Text I'd like to change this to some fool-proof graphical solution like this: NSTokenField
