I need my Xamarin.App to run in background and show up it's window whenever globally available is pressed.
How can that be done with Xamarin.Mac?

I'm trying to create a macOS app that lets the user drag and capture portion of the screen, and analyze the captured image. I want to make it so that the screen capture is triggered by entering a keyboard shortcut (just like the macOS screen capture feature: https://support.apple.com/en-sg/HT201361). How do I build an app that launches with a keyboard shortcut?
I've writing a macOS application with Qt. This application is a launch agent, meaning that it's launched by launchd and always running in the background. Normally the application only has a menu bar icon, and it doesn't have any open windows or a Dock icon. (i.e. the shared NSApplication instance's activationPolicy property is set to a value of NSApplicationActivationPolicyAccessory.)
However, there are a few menu items available in its menu bar item that open some windows, and when those windows are open the app switches to not being background-only any longer, so it will have a Dock icon and menu bar. (i.e. activationPolicy is changed to NSApplicationActivationPolicyRegular.) With there being a Dock icon, that means it's possible for the user to right-click it and open its menu, and that menu has its default menu item for quitting the application.
Since the app is a launch agent, though, and is intended to always be running, quitting it just causes launchd to relaunch the app. I'd like to disable or remove this menu item if possible, or otherwise prevent the user from being able to quit the app in this manner.
Is there any way to do that? If there's a way to accomplish this purely using Qt's functions that would be great, but if not it's fine for me to use macOS specific functions too.
I should add that because this is a Qt application, I can't use the same method as outlined here because I don't have access to the application's delegate. I would need to use another approach. (For example, it may be possible to swizzle methods on Qt's application delegate, though if there's a cleaner way to accomplish this than I'd much rather do that.)
After doing some more research, I've found that it's not possible to remove the "Quit" menu item from an application's Dock menu, or any of the other standard menu items there as they are created and handled by the Dock itself.
It is possible to stop an application from quitting when the user quits the application via the Dock. In a Qt application the method is to subclass QApplication and override its bool event(QEvent *) method. The overridden method should check for events of type QEvent::Close, call the ignore() method on the event, and then return true. Note though that this will stop the application from quitting via all other conventional methods as well.
edit: It is also possible to tell when the app is being quit via the Dock, at least when using Apple's native API. See: macOS: Is there any way to know when the user has tried to quit an application via its Dock icon?
By using Objective-C method swizzling it's possible to override the applicationShouldTerminate: method of Qt's application delegate and prevent a Qt app from being quit by the dock.
I am trying to find the event type associated with windows taskbar icon of my application. In Windows 8.1 user can close, minimize and restore the application from this icon.
Google is only showing the results for taskbar tray icons, which is a whole different thing. So far I've tried these:
wx.EVT_CLOSE # This event is not generated for taskbar closing
wx.EVT_RESTORE # This event is not generated either
Yet, it does close the application and it also manages to restore an iconized application. I made two separate handlers to check this. They are working when I use the titlebar buttons (close and min/maximize buttons), but not when done from the taskbar.
I've submitted a helper application (using LSUIElement)to the Mac App Store. I was under the false impression that the App Store install process would put a dock icon for helper apps.
How can I create a dock icon that the user could remove, while the status bar app runs independently (like the popular app Caffeine)? Do I need to create a non-LSUIElement app that loads the LSUIElement app, or is there a better way?
Instead of using LSUIElement, use NSApplication's setActivationPolicy: method. By default, the application will have a dock icon, but by changing the activation policy to NSApplicationActivationPolicyAccessory, you get the same effect as LSUIElement while being able to change it programatically (the documentation for NSApplicationActivationPolicyAccessory says it is equivalent to LSUIElement=1).
- (void)applicationDidFinishLaunching:(NSApplication *)app {
if([[NSUserDefaults standardUserDefaults] boolForKey:#"HideDockIcon"])
[NSApp setActivationPolicy:NSApplicationActivationPolicyAccessory];
}
Apparently I was misinformed by my app reviewer (two of them actually). The dock icon is created for you by the install process. Pressing the issue, I was able to get the app through the review process.
