I have a NSMenu coming down under a NSStatusItem. I also have a NSSpeechRecognizer. When the NSMenu is open, the speech recognizer does not function properly. It will constantly show that it's receiving sound, until I close the menu. I need it to detect sound properly even while the menu is open.
How can I make the speech recognizer detect sound even while the menu is open? Does it need to become a "first responder" and take precedence over the menu?
I tried setting [speechRecognizer setListensInForegroundOnly: NO] and it still won't work.
If you don't understand, I am more than happy to provide clarification.
Here are some similar situations, but I don't yet fully understand.
The problem is most likely that the menu is running a modal run loop as long as it is open (for the purposes of tracking the mouse, etc...) and this is blocking the NSSpeechRecognizer's ability to function normally.
You can confirm this by bringing up the menu and then pausing into the debugger. You'll likely see two run loops; the outer, normal, one and one deeper down the stack that is running the modal loop.
In general, this is kind of an odd thing to do from a user interaction perspective. The whole point of a pop-up menu is to offer the user some commands that will be done after the corresponding menu item is selected.
If you really need "click this thing and recognize voice", I'd recommend a button that, maybe, pops up a bit of UI and then interacts with the speech recognizer without using a menu?

I'm a new Mac programmer writing my first mac app, actually porting an existing iOS app to MAC.
The app does a lot of remote communication, so when the user kicks off an operation, I want to display a busy window (or message box, or NSAlert maybe), until the operation is completed, then dismiss it programmatically, or the user can click cancel to stop it.
The busy window prevents the user from doing anything until that operation is completed.
The busy window should have a progress spinner, some text, and a cancel button.
Its such a simple thing yet I'm having problems with it because I dont really know MAC programming, getting myself frustrated.
Can anybody offer suggestions, or already written code for it. I hope some code for this already exists because I cant believe I'm the only person in the world who needs things kind of busy window.
Thanks for any help.
You mean something like this:

???
Source code is available, too (link at the end of the article).
You can just modify the NSPanel in Xcode and add a "Cancel" button that you connect to your cancel action.
I've removed the menu from my cocoa app, all of the interaction should happen from within a status item, that links to a menu, that links to different NSPanels. But this seems to have removed the ability to ⌘C or ⌘V within a NSTextField. Is there a way to add this back without having to have a standard menu included with my app?
Even if your app is a faceless background app, so it never shows a menu bar, you should still have a full main menu because that's what provides all of the default actions (and enables the user to redefine the key commands if they so choose). If you remove the main menu, you have to reimplement everything in it, including anything Apple adds in the future, in code.
And I'd especially warn you against trying to handle keyboard shortcuts yourself. That's damned tricky. A lot of applications get it wrong, causing us Dvorak users (among others) to curse their developers.
I assume you can just implement the actions originally connected to the menu items in a keyDown event. Check out this page for details: http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/EventOverview/HandlingKeyEvents/HandlingKeyEvents.html
Just have it respond to cmd-v with paste:, and cmd-C with copy:
Edit: Though I have to agree with Peter, you really should have a main menu...
I want to check for changes in the aplication state every time interval, and if it has changed, to open a window, and give the user 10 seconds to press on the window, if he does press on the window, then to allow him to navigate freely in the window, and if he doesn't press, to return back to the window before. I thought to implement it with a thread running in the background and waking up every time interval I want. Maybe there is a better way?
This strikes me as a scenario with lots of potential issues.
How do you stop the "window" appearing at an inconvenient time to the user? (e.g. when they were just about to tap on som.ething)
Why not just raise the notification when the state actually changes? This way you wouldn't need to poll.
What is the "Window" you are displaying? How does it differ from the page it is replacing? Is this a popup or are you actually navigating to a different page?
What is the state that's changing? How is it changing without user interaction?
Can't you notify the user of the state change without a potentially intrusive display of a new "window"?
I agree with #matt-lacey, this could be dangerous and might result in a bad user experience.
With that said, this might work
Deployment.Current.Dispatcher.BeginInvoke(() =>
{
//navigation code here
});
I didn't know you could do a pop-up window, could you elaborate?
I've made a thread that is running at the background and making some work, if it decides that a change is necessary, I want to give the user a chance to react to it, or ignore it.
I'm pretty new to this, so if there is a better way than to navigate to a different page i would love to hear it.
Thanks.
It sounds to me like you want to notify the user that something has happened/changed and give them the option to do something about it, which is exactly what "toast" notifcations are all about. They pop up at the top of the screen to inform the user, and then the user can tap that toast to do something, e.g. when WiFi networks are available, you tap the toast to select an available network.
The Silverlight Windows Phone Toolkit includes the ToastRequestTrigger that you use to display toast notifications. The Windows Phone Developer Guide from the patterns & practices team gives examples of using the ToastRequestTrigger. You will need to implement the tap handling yourself in the toast content, but this should be simple enough.
I've been searching forever for a solution to this, so I thought I'd seek out the brainpower of greater minds than mine. I'm developing a Cocoa app that uses the Accessibility API to manipulate another program (it's a hotkey app). The app I'm controlling typically has multiple windows open, with some hidden behind others. What I would like to do, if it's possible, is to send mouse events to windows using the Accessibility API in a way that presses a button in the window without bringing it to the foreground (interact with the window but don't activate it). The reason I'm trying to do this is that sending the mouse event to this other window will force it to the foreground and disrupt the user's interaction with the foremost window.
This is possible on Windows - apparently, because apps similar to mine do it there - but I'm getting the feeling that this isn't possible with Cocoa, given the way the window manager works. Am I mistaken?
Accessibility is higher-level than that. You send, for example, AXPress actions to AXButton objects, but “press” is not necessarily a click—pressing the space bar while a view is focused, for example, is also a “press”. AXPress is a high-level action that means “do your thing”, which obviously has meaning for some views (such as buttons) and not others (such as fields).
Accessibility activating the application does make sense when you look at it from its intended purpose: Assistive devices for disabled users. If the user “presses” something by whatever means, they probably intend to activate the application and work in it.
Quartz Event Services will get you almost there: You can create an event tap for the process you want to control, and you can forge events and send them to a tap. The catch is that you can only send events to a tap when the tap fires—i.e., when the application already has an event to deal with. When it doesn't, you're stuck.
I have a program with many windows open. I want all windows to be visible, but only one window can be interactable, until a certain event has occured. e.g. pressing a button.
At the moment, I can still click another window, and interact with it, how do I only allow interaction with ONE window, until a certain event occurs?
Imagine this as the program:
I want only the frontmost Window to be selectable, if I try to select any of the other windows behind it, it should not work.
Does anoybody know how to do this?
Thanks!
Michael
It sounds like you want a modal window.
