nswindow

I have an Xcode project with an NSWindowController whose contentViewController was set to a subclass of NSViewController . I recently removed the NSViewController subclass from the storyboard and replaced the contentViewController with an NSTabViewController subclass. Now, when I run the application, the NSWindow opens with a size of 500x500 instead of the size of the first tab. What's more, there is no view I can see in the storyboard that has a size of 500x500, and that size isn't being programmatically, either. The window itself is set to a different size, as is the view in the

I added a childWindow of a custom subclass of NSWindow to a parentWindow (also a custom subclass of NSWindow). The childWindow has the NSBorderlessWindowMask and canBecomeKeyWindow: is overridden to return YES and canBecomeMainWindow: to return NO. The childWindow is set to resize with the parentWindow. So I want to create the illusion that the views of the childWindow are part of the parentWindow. The main idea is to arrange the document windows created by the document-based application within a main window to provide a tabbed interface (just like in a browser) to switch between the documents

I think it's a first responder problem, but I'm not sure. I'm implementing an edit window for data in a table view. Very similar in concept to the UI for editing filter rules in Mail.app. I have an editing window that I attach to my primary window with: [NSApp beginSheet: criteriaEditPanel modalForWindow: [self window] modalDelegate: self didEndSelector: @selector(criteriaEditDidEnd:returnCode:contextInfo:) contextInfo: (void *)[criteriaList objectAtIndex: index]]; The panel displays properly, from the title bar of the main window. I can manipulate the pop-up controls on the panel with the

I'd like to know how to setup a transparent overlay windown in Cocoa which can ignore mouse clicks (so that they pass through to whatever window is below). The user should not be able to interact with the window with their mouse. Tell it to ignore mouse events. 来源： https://stackoverflow.com/questions/3570247/how-to-create-a-topmost-overlay-which-ignores-mouse-clicks-etc

I'd like to get a window that has a semi-transparent blurred background, just like what the Terminal can do. See this video, about 30 sec in, to see what I mean: http://www.youtube.com/watch?v=zo8KPRY6-Mk See an image here: http://osxdaily.com/wp-content/uploads/2011/04/mac-os-x-lion-terminal.jpg I've been googling for an hour, and can't get anything to work. I believe I need to somehow create a core animation layer and add a background filter, but I've been unsuccessful so far... I just see the gray background of my window. Here's the code I've got so far: Code: // Get the content view --

Is there a way to get the NSScreen for a window of another process assuming that I have the window id? I got pretty close with the following code, but the info dictionary doesn't say which screen the window is on. CFArrayRef windowArray = CGWindowListCopyWindowInfo(kCGWindowListOptionOnScreenOnly, kCGNullWindowID); NSArray* windowList = (NSArray*)CGWindowListCopyWindowInfo(kCGWindowListOptionOnScreenOnly, kCGNullWindowID); NSUInteger count = [windowList count]; for (NSUInteger i = 0; i < count; i++) { NSDictionary* nswindowsdescription = [windowList objectAtIndex:i]; NSNumber* windowid =

I have a NIB which contains two windows, one is the app's main window visible at launch and the other is a custom sheet (and therefore not visible at launch). When the sheet is required my controller calls: [NSApp beginSheet: sheetWindow modalForWindow: mainWindow modalDelegate: self didEndSelector: @selector(didEndSheet:returnCode:contextInfo:) contextInfo: nil]; which displays the sheet window and starts a modal session, but the window has a standard Aqua title bar, is not 'connected' to the main window and can be moved around just like a regular window. Needless to say, this is not
