问题 How can I get the NSMenu or NSMenuItem for the application menu (the one in the menu bar next to the apple menu). It seems to be automatically created and independent from the NSMenu I set via NSApplication setMainMenu. By the way: I'm building my complete application without Xcode, so please no InterfaceBuilder tips. PS: MacOSX 10.5 回答1: Without IB, you can access the menu using the NSApplication's mainMenu: NSMenu *mainMenu = [[NSApplication sharedApplication] mainMenu]; NSMenu *appMenu = [

问题 I'm want to create a menu for a status bar item like the one seen in Tapbot's PastebotSync application: Does anyone have any ideas how to achieve the custom area at the top of the menu which is flush with the top? I've tried/thought of a few potential ways of doing it: Standard NSMenuItem with a view - isn't flush with the top of the menu Some hack-ish code to place an NSWindow over the area at the top of the menu - not great as it doesn't fade out nicely with the menu when it closes

问题 I am using NSAttributed NSString in my NSMenuItem, but it's Font is changed as compare to default font, I wants to use default font for Attributed string. Can any one explain, how to find or fetch the default Font for NSMenuItems.

问题 I have a weird data leak and hope someone can explain what is going wrong here. The minimal working example project is as follows: Create a new Objective-C macOS project (Cocoa-App). Delete everything except Info.plist and main.m In Info.plist do: Delete the entry Main nib file base name . Change Principal class to "AppHook". Add LSUIElement and set it to YES . Next, change main.m to: #import <Cocoa/Cocoa.h> #import "AppHook.h" int main(int argc, const char * argv[]) { [[AppHook

问题 I am using an NSPopUpButtonCell in an NSTableView . The popup button has a binding to an NSArray property offered by the ApplicationDelegate . When I select a menu item of the popup button I expect to retrieve the current selection or its index . I added an IBAction to being informed and also set up an NSMenuDelegate . Both return index = 0 at all times. // indexOfSelectedItem is always 0. NSInteger indexOfSelectedItem = [m_popUpButtonCell indexOfSelectedItem]; I created an example project

问题 I was trying to use NSMenuFX from https://github.com/codecentric/NSMenuFX to make a JavaFX app use the MacOS System MenuBar, and it didn't work because of this method returning always false . Toolkit.getToolkit().getSystemMenu().isSupported() The method is from the package : com.sun.javafx.tk.Toolkit . Going deeper in the code I've found that Toolkit.getToolkit().getSystemMenu().isSupported() calls a method from com.sun.glass.ui.Application that returns always false too. protected boolean

问题 In Cocoa i want to create an nsbutton with delayed menu. i.e., When clicked it should call the action method and when kept in pressed state for 2 seconds it should display a nsmenu. It is similar to "Build Active Target" button present in Xcode toolbar. Regards, Dhanaraj. 回答1: It's a NSPopUpButton.. Here is how I create it in my app. NSToolbarItem* item = [[[NSToolbarItem alloc] initWithItemIdentifier:identifier] autorelease]; [item setLabel:label]; [item setPaletteLabel:label]; [item

问题 I'm familiar with the technique described here: Drag and Drop with NSStatusItem to make an NSStatusBar item that can handle file drag & drop. What is the proper method for having a status bar item that supports both drag & drop and regular menu interactions, much like the Cloudapp icon does. I want users to be able to left click the NSStatusItem to see the normal menu listing as well as allow for file drag and drop functionality. It seems to me like I have to write all my own click handler

问题 Is there any way to customize NSMenu appearances, for example, its transparency, background color or foreground color using public API"S (like Apple's Dock right click Menu) ?? After lots of search i have found some code where they are using private API's for making the menu dark !!! 回答1: I think you'll have better luck if you just use a custom view which you code to look however you want and to behave like a menu. Apple provides a sample project, CustomMenus, which illustrates that technique
