column

My solution to this problem has (for a long time) been to make the columns of the table not editable. But, in my case, I'm using the double click action as a means of getting to an editor to edit the whole row, as the row is only a very limited representation of some aspects of the underlying object.Rod

Thanks for the reply. Making the columns uneditable makes no difference, I'm afraid. Are you using cell-based tables by any chance? I used to take that approach with cell-based tables, but with view-based tables you disable editing at the text field level. But if the text fields aren't set to editable, then click-after-delay doesn't work (for when you want to click and then click again instead of triggering the double-click action).

Hi,If there isn't a class somewhere at the web, which does exactly what you need, you have to implement it on your own. I've created a collectionViewLayout with a fixed column with and a variable item height. And yes, you have to do all the calculations yourself. But for a grid-style layout this should by quite easy to implement. I suggest reading some docs but the most important part of a UICollectionViewLayoutAttributes object is the frame, which tells the collection view where to put the collection view items at.Dirk

Ok I threw together a quick and dirty app to test the normal mechanism and it works fineThe app delegate, which again is also the table delegate and data source, looks like this@interface AppDelegate () <NSTableViewDataSource, NSTableViewDelegate> @property (weak) IBOutlet NSWindow *window; @property (nonatomic, strong) NSArray *data; @end @implementation AppDelegate - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { self.data = @[[@{@name:@Jonathan} mutableCopy], [@{@name:@Richard} mutableCopy]]; [self.window makeKeyAndOrderFront:nil]; } - (void)applicationWillTerminate:(NSNotification *)notification { NSLog(@%@, self.data.description); } - (NSInteger)numberOfRowsInTableView:(NSTableView *)tableView { return 2; } - (id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row { return [[self.data objectAtIndex:row] valueForKey:tableColumn.identifier]; } - (void)tableView:(NSTableView *)tableView setObjectValue:(id)object forTableCo

Here is the code for my main.swift file - as the code shows, I still use a MainMenu nib that loads the standard menu items in Interface Builder:import Cocoa private func setDelegate( application: NSApplication , delegate: NSApplicationDelegate? ) -> NSApplication { application.delegate = delegate return application } private func runApplication( application: NSApplication = NSApplication.sharedApplication() , delegate: NSApplicationDelegate? = nil , bundle: NSBundle = NSBundle.mainBundle() , nibName: String = MainMenu , var topLevelObjects: NSArray? = nil ) { if bundle.loadNibNamed( nibName , owner: setDelegate(application, delegate: delegate) , topLevelObjects: &topLevelObjects ) { application.run() } else { print(An error was encountered while starting the application.) } } runApplication(delegate: AppDelegate())And here is my AppDelegate file:import Cocoa @NSApplicationMain // This is commented out when I am using main.swift; // That is the only difference in my AppDelegate file between the two scen

Thanks. It looks like the column not having an identifier set was where I went wrong.However, I also found another way to get the edited values from the table. // this bit goes in applicationDidFinishLaunching [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(editingDidEnd:) name:NSControlTextDidEndEditingNotification object:nil]; // this notification is sent by the table cell field editor - (void)editingDidEnd:(NSNotification *)notification { NSControl *control = [notification object]; NSView *cellView = [control superview]; NSInteger tableRow = [keyTable rowForView:cellView]; NSString *cellText = [control stringValue]; [keysList replaceObjectAtIndex:tableRow withObject:cellText]; }I got this from Technical Q&A QA1551. The table cell's field editor sends the notification when the user finishes editing (tabs out, clicks elsewhere, hits return).

I guess menuForEvent: must get called on a subview of NSBrowser, and it must eat it. There doesn't seem to be a clean way to handle this. I can override menuForEvent: on a NSMatrix subclass, if I set a custom matrix class..though that API is deprecated.What I want to do, is when a user right-clicks, and no column/row is selected, I want nothing to happen (no menu to show). I can be a bit hacky by using validateMenuItem: and hiding everything in there. Doing this isn't great either, because I can right click in a different column than the selected column and the menu will show...since I don't have the NSEvent to check the location of the click against, it seems that I have to add another layer of nasty code by converting the current cursor's position. None of this feels clean.Edit: Seems that I can set the menu property on each cell in browser:willDisplayCell:atRow:column:Far as handling right clicks in blank areas and showing an alternative menu depening on what that column

Yeah, the getter for menu gets called from the addColumn method. It seems that everytime NSBrowser adds a column, it sets the menu for that column (whatever view it uses for the column) to be its menu. The main view used to create each column, far as I can tell is private API.What I'm going to try is:1) Setting the menu directly for each cell.2), Setting a different menu for the browser.3) Take hack-ish measures to validate the browser's menu to block it from being shown by hiding all the menu items when necessary.If there is a more elegant way to this, I'd love to know.
