How to change the background color of an NSPopupButton?

由 十年热恋 提交于 2021-02-08 15:54:46
问题 I am trying to tackle a problem which sounds pretty simple: changing the background color of an NSPopupButton. Interface Builder only allows changing the style to a pre-defined one and doesn't allow changing the background color. Also, setting up an IBOutlet didn't help since NSPopupButton doesn't have a setBackgroundColor method. I also tried subclassing NSPopupButton to override the drawRect method. Here's what I have tried: - (void)drawRect:(NSRect)dirtyRect { [[NSColor redColor] setFill];

Separator item in NSPopupButton with bindings

由 天大地大妈咪最大 提交于 2020-01-03 07:21:28
问题 The contents of a NSPopupButton are bound to an NSArray of strings. How can we insert a separator item via bindings? The " - " strings (like in the olden/Classic days) doesn't work, i.e. shows up literally as a " - " menu item. Is there any out-of-the-box solution with standard Cocoa classes and bindings? This should be a trivial problem but I can't find any solution to the problem that doesn't involve silly hacks like subclassing NSMenu , NSPopupButton or other non-intuitive work arounds.

Using full width of NSPopupButton for text, no arrows

问题 I like to display an NSPopupButton that has no arrows. I like to use that space where the arrows would be for the label text. That doesn't seem to work by default. Here's the text (which is "01234567890") with the arrows enabled: And here with no arrows: As you can see, the space the arrows would occupy is not used by the text. How can I use the full content width for the text? I've inspected the control with F-Script but found that the control's subviews array appears to be empty - I had

A popup button with a static image (Cocoa OSX)

问题 I am trying to make a popup button that always displays a + as its image and when you click on it, a context menu pops up that will allow you to decide what type of object you want to add. Is there anyway to do this using an NSPopupButton? I saw in the specs for NSPopupButotn that the method SetImage has no effect so it seems that this is likely not going to work using this class. Is this correct? 回答1: Yes, the visible appearance of NSPopUpButton is wrong for what you want. What you want is a

NSPopUpButton + Bindings + Show All Option

由 天涯浪子 提交于 2019-12-09 01:05:29
问题 I'm trying to develop a NSPopUpButton that will serve as a filter to some datasource, let's say a NSArrayController that fills a table. I can bind the NSArrayController from the menu to the selection keypath so the data is properly filtered, no problem with that. Tricky part is, I want the content of this NSPopUpButton to rely on an NSArrayController using bindings, but I'd like to add a "Show All" menu item, or at least some item that doesn't come from the Core Data and performs some special

Problem: Take an instance of NSPopupButton of type Pull down. Add few menu items to the pop up. Run the code. Select any menu item in the popup Title of popup button is not getting changed.
