问题 I have a background "monitoring" app that runs either as an accessory or as a regular app (user choice depending on whether they want to see it in the dock). The app has several never-key utility windows ( NSPanel s) that display the progress of background tasks. When a background task starts, the window is made visible using orderFront: . This has worked great for years; the window would simply appear somewhere behind the active app. Starting in Catalina (macOS 10.15), however, orderFront:

Allow an NSWindow (NSPanel) to float above full screen apps

问题 I'm trying to add a little window that provides "quick input" from any place in the system to the main app. The user could hit a hotkey, the window pops up, and floats above all other windows. For the most part, this isn't much of a problem. I can configure an NSWindow to be: level = Int(CGWindowLevelKey.TornOffMenuWindowLevelKey.rawValue) collectionBehavior = .CanJoinAllSpaces I can also make it an NSPanel with NSNonactivatingPanelMask option set. The only problem is: how can I make it so

问题 I have an app winth one window and one panel, attached to this window. steps: deactivate my app (app opened, but without the focus) click on a button on panel (panel is focused now, but main window is not) How to set focus to the main window (parent window) from the panel? 回答1: It is not clear what you mean by focus, and whether what you call main window is a main window as defined in Cocoa. Assuming it is a Cocoa main window and focus is the same as key status, [[NSApp mainWindow]

问题 I am using NSSavePanel to save image. I have used IKSaveOption which gets added to the NSSavePanel.

How to create a NSPanel modally popuped from NSWindow (Cocoa programming)

问题 like NSPanel displayed after a button clicked in the NSWindow. I looked for a lot but there is no simple example. Thanks for any help. 回答1: It can be done like this: -(IBAction)showButtonAction:(id)sender { [[NSApplication sharedApplication] beginSheet:panelOutlet modalForWindow:self.window modalDelegate:self didEndSelector:@selector(sheetDidEnd:returnCode:contextInfo:) contextInfo:nil]; } Attention: Don't forget to uncheck NSPanel 's Visible At Launch checkbox in Attributes Inspector and

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . It took me quite a bit of experimentation to clear up some confusion over Objective-C’s “ModalForWindow” language and, subsequently, how to use a modal session.

It took me quite a bit of experimentation to clear up some confusion over Objective-C’s “ModalForWindow” language and, subsequently, how to use a modal session. Maybe the following tips will save somebody some time: (In case you’re new to the concept: When a window, usually a panel, runs modal, it prevents some other part of the app from responding until it has been dismissed.) “ModalForWindow” means different things in different circumstances. If you are using loadNibNamed to display a panel defined by a xib and you want it to run modal, call this once it is displayed: // Make

UPDATE | I've uploaded a sample project using the panel and crashing here: http://w3style.co.uk/~d11wtq/BlocksCrash.tar.gz (I know the "Choose..." button does nothing, I've not implemented it yet). UPDATE 2 | Just discovered I don't even have to invoke anything on newFilePanel in order to cause a crash, I merely need to use it in a statement. This also causes a crash: [newFilePanel beginSheetModalForWindow:[windowController window] completionHandler:^(NSInteger result) { newFilePanel; // Do nothing, just use the variable in an expression }]; It appears the last thing dumped to the console is
