问题 I have main window and several child windows, i would like to show main window when user click on dock icon, but without making it a key window, if there just was one (it will become automatically key if there is no key window). Here is current code: if ( fMainWinDelegate ) { if (not [NSApp keyWindow]) { NSLog(@"AppDelegate::applicationShouldHandleReopen [fMainWinDelegate showWindow]"); [fMainWinDelegate showWindow]; } else { if ([fMainWinDelegate.window isMiniaturized]) { NSLog(@"AppDelegate

问题 how can I take notice when an NSWindow should or will get closed? I'd like to have something like the windowWillClose. Unfortunately NSWindowController does not have as much convenient methods as UIViewController has, for example. So what's the best practice to do that?

It gives two options to select from Single Multiple P.S When googled the title, results are related to powerpoint presentation 回答1: The presentation style affects "Show" segues. Possibly it affects other segues too, but I only tested a Show segue. I tested on OS X 10.10.5 (Yosemite) with Xcode 7.1.1.

问题 I'm trying to open a window using a NSWindowController in my app delegate. I created a basic NSWindowController with an associated NIB and try to show the window that way: @implementation MyAppDelegate - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { // Show the main window from a separate nib MyWindowController * theWindowController = [[MyWindowController alloc] initWithWindowNibName:@"MyWindowController"]; [theWindowController showWindow:self]; } @end When I launch

问题 I create a subclass of NSWindowController from File->New, and with the "With XIB for user interface" option checked. So I create 3 new files. Then I use Interface Builder to add exactly ONE view into the window. And have this code in MyWindowController.m: - (void)keyDown:(NSEvent *)theEvent{ NSLog(@"%@", theEvent); } First test, add one NSButton, and run the project. Second test, add one WebView(NSButton deleted), and run the project. In both tests, the window shows up correctly. But the

问题 In Mavericks, the methods to open and close NSSheets has changed. And to make it tougher, the Release Notes do not match the current documentation (see below).

I did have this code working: - (IBAction)activateSheet:(id)sender { if (!_sheet) [NSBundle loadNibNamed:@"Sheet" owner:self]; [NSApp beginSheet:self.sheet modalForWindow:[[NSApp delegate] window] modalDelegate:self didEndSelector:NULL contextInfo:NULL]; } but the loadNibNamed method is deprecated. So I substitute this: - (IBAction)activateSheet:(id)sender { if (!_sheet) NSLog(@"1"); [[NSBundle
