Software equivalent "Visible at Launch" for NSWindows

Question

I am trying to write the software equivalent of the nib file that I installed, which contains two windows: the main window and the sheet that appears after startup to request credentials. Posting them to IB works fine, if you remember, to clear the "Visible at startup" checkbox on the sheet / window.

However, I cannot figure out what the Visible at Startup API is equivalent to. When I launch my application using the software version, the sheet is separated, not the key, just as my application was launched using a bandage when the "Visible at launch" checkbox was selected. Therefore, my assumption is that I do not have enough secret sauce with visible start.

Does anyone know how to do this?

PS I know how to do this job in IB, I specifically want to calculate the code equivalent, so please don't tell me to just use the tip. I know it.

NSWindows are usually created hidden. Therefore, you do not need to do anything; just don't show the window until you need it. Here is a simple example.

NSWindow *sheetWindow = [[NSWindow alloc] initWithContentRect:NSMakeRect(0, 0, 100, 100) styleMask:NSTitledWindowMask backing:NSBackingStoreBuffered defer:NO]; NSTextField *field = [[NSTextField alloc] initWithFrame: NSMakeRect(25, 25, 50, 50)]; [[sheetWindow contentView] addSubview:field]; [NSApp beginSheet:sheetWindow modalForWindow:[self window] modalDelegate:self didEndSelector:@selector(sheetDidEnd:) contextInfo:NULL]; 

The text box got the keyboard focus at startup above.

In the future, please provide code in such cases - it is much easier to fix existing code than to write new code.
