nsbutton

I´m newbie with cocoa. I have a button and a textField in my app. I want the button disabled when the textfield is empty and enabled when the user type something. Any point to start? Any "magic" binding in Interface Builder? Thanks [EDITED] I´ve tried to set the appDelegate as the NSTextfield´s delegate and added this method (myTextfield and myButton are IBOutlets): - (void)textDidChange:(NSNotification *)aNotification { if ([[myTextField stringValue]length]>0) { [myButton setEnabled: YES]; } else { [myButton setEnabled: NO]; } } But nothing happens... I´ve tried to set the appDelegate as the

I am creating a custom NSButtonCell for a custom rendering. Now, I want to have different aspect depending if the mouse is over the button or not. How can I get this information? Thanks and regards, Here is i have created and worked for me perfectly... Step 1: Create the Button with tracking area NSButton *myButton = [[NSButton alloc] initWithFrame:NSMakeRect(100, 7, 100, 50)]; [myButton setTitle:@"sample"]; [self.window.contentView addSubview:myButton]; // Insert code here to initialize your application NSTrackingArea* trackingArea = [[NSTrackingArea alloc] initWithRect:[myButton bounds]

I would like to know how to change title color to a NSButton in swift, I've seen lots of examples in objective-c but I think in swift the implementation is different, can anyone provide me an example? bluedome try this in viewDidLoad or somewhere. In Swift 3: let pstyle = NSMutableParagraphStyle() pstyle.alignment = .center button.attributedTitle = NSAttributedString(string: "Title", attributes: [ NSForegroundColorAttributeName : NSColor.red, NSParagraphStyleAttributeName : pstyle ]) Swift 4 I've added this as an additional answer since it changes only the requested attribute without

I just ran into a problem I already know from other programming languages/frameworks .... Whenever the user clicks a certain button on the keyboard, he triggers the same action than when a certain button in the GUI is pressed. ( Some guys call these "shortcuts" ;D ) To give the user an optical feedback, I would like to sorta "click" the button programmatically rather than calling the same functions that get called when the button is clicked. If I set the button as a key equivalent in IB, it looks exactly as I want to have it. Can't do that here as the shortcut should just be enabled if the

I just want to add a NSButton with setAction Arguments. NSRect frame = NSMakeRect(10, 40, 90, 40); NSButton* pushButton = [[NSButton alloc] initWithFrame: frame]; [pushButton setTarget:self]; [pushButton setAction:@selector(myAction:)]; But I want to put an argument to the function myAction... How ? Thanks. But I want to put an argument to the function myAction... How ? You can't. … if there is more than one button that uses this method, we can not differentiate the sender (only with title)... There are three ways to tell which button (or other control) is talking to you: Assign each button

In Cocoa/Objective-C if I have created a button programmatically, what do I put in for my control event? [btnMakeChar addTarget:self action:@selector(makeChar:) forControlEvents:WHAT GOES HERE?]; In iOS you can write it like so forControlEvents: UIControlEventTouchUpInside I can't find anything to show what I would use for just cocoa, not cocoa touch I'm not sure if I understand you correctly, but if you're programming a Mac, [theHappyButton setTarget:self]; [theHappyButton setAction:@selector(doStuff)]; it is two separate lines, rather than the one combined line of code on an iPhone. I hope

I only know few ways to show a keyboard on iOS touch textfield,search bar,textview..... Is it can via touch a button to show keyboard ??? I wish I can use this way to set a button tittle if the button is no tittle or can rename it. Thank you guys~ Constantin You need to add an UITextField to your view and call then [myTextfield becomeFirstResponder]; Its possible to set the hidden attrribute from UITextField to YES - so the user will never see the textfield. After Keyboard input is finished you can remove the UITextField with removeFromSuperview . Maybe a little bit dirty, but thats the
