Initializing Controls in NSPanel

I've got an NSPanel in my app that I use as a data export feature.

How do I initialize the controls in the panel when it's initially displayed? (i.e. using NSDefaults). There doesn't seem to be an event that fires when the window/panel opens where I can restore the default settings (basically just restoring the value of an NSPopupButton).

Currently, I'm opening the panel using '[NSApp beginSheet...]' in my App Delegate class. Should I be using an NSWindowController subclass instead?

Solution

  • Don't subclass the NSWindowController, simply subclass the NSPannel itself.

    ExportPanel.h

    #import <Cocoa/Cocoa.h>

@interface ExportPanel : NSPanel {

}

@end

    ExportPanel.m

    #import "ExportPanel.h"

@implementation ExportPanel

- (void)awakeFromNib
{
    // Initialize here
}

@end
