    My Cocoa app needs some small dynamically generated windows. How can I programmatically create Cocoa windows at runtime?This is my non-working attempt so far. I see no result whatsoever.NSRect frame = NSMakeRect(0, 0, 200, 200); NSUInteger styleMask = NSBorderlessWindowMask; NSRect rect = [NSWindow contentRectForFrameRect:frame styleMask:styleMask];NSWindow * window = [[NSWindow alloc] initWithContentRect:rect styleMask:styleMask backing: NSBackingStoreRetained defer:false]; [window setBa

    runtime-error nswindow setbackground
    I added a background color to the window of a well-running simple draw project and build succeeded. Then the fun began: runtime errors appeared in the console window. I found no help in Apple docs and Google. When the same happened in another draw project, I knew I had to ask for help.Here’s what happened each time I did a build & debug and stop — runs 1) through 4). “continue” means I clicked the Continue icon. It kept on erring in no consistent order.1)Program received signal:”EXC_BAD_ACC

    osx cocoa nsview nswindow appkit
    I have a problem understanding how to initialize a view without hooking it up in my nib-file. So what I want to do is, instead of dragging in a view and assigning it a dedicated class, I want to programmatically add it to my window in my app delegate. I don’t really know how wrong this is, but I tried something like this in my AppDelegate: – (void)applicationDidFinishLaunching:(NSNotification *)aNotification {DView *dV = [[DView alloc]initWithFrame:NSMakeRect(0, 0, 1000, 600)];[self.window addS

    I’m currently building a C++ plugin for some software, which, when the relevant function is called, displays a nib which I built in XCode. Up until today everything has been working fine, displaying and working with the nib / Objective-C++ / C++ has caused no problems.However out of the blue everything started crashing at the call to show the preferences dialog. I’ve narrowed the crashing code down to this line:PreferencesWindowController *prefsWindowController = [[PreferencesWindowController al

    objective-c cocoa nsview nswindow
    I have an NSWindow with 2 NSViews (an NSSplitView and a custom NSView). Accessing the data to populate these views can take some time. During this period, I’d like to gray out the content of these views. My first approach was to have a black third NSView that covered the other 2 and achieve the graying out effect by changing its alpha value. However I’ve since learned having a hierarchy with sibling views is undefined. What is the best approach here?Cache the NSBitmapImageRep of the 2 views, the

    I show modal subclassed window:NSWindowController* controller = [[NSWindowController alloc] initWithWindowNibName: @”MyWindow”]; [NSApp runModalForWindow: [controller window]];And I override initWithContentRect:(NSRect)contentRect styleMask:(NSUInteger)aStyle backing:(NSBackingStoreType)bufferingType defer:(BOOL)flag in my window subclass to setup children views which are linked to nib file. But these children are not initialized at this moment (are nil).Where to place my initialization code?
