Trying my hand at Mac Cocoa for the first time. Lion and XCode 4.1.
My little app is supposed to save a date and a task. I'm using 2 buttons, a scroll view, and an array controller. One button is for adding, the other for deleting.
The add button has no effect, and execution doesn't stop at a breakpoint in the handler. I know it's a broad question, but can anyone point me at what to look at? I think it's all wired correctly, but obviously not.
Make sure you actually connected your buttons to an action, either on a specific desired target or on the First Responder.

Set up the application state.
Take an action.
Make an assertion about the resulting application state.
You might also see this phrased as "Given, When, Then", or "Arrange, Act, Assert". But the idea is: First you put the application into a specific state, then you take some action in the application that causes it to change, and finally you check the resulting application state.
Today, we'll take a narrow view of these steps and map them cleanly to Cypress commands:
Visit a web page.
Query for an element.
Interact with that element.
Assert about the content on the page.
Save the file and switch back over to the Cypress Test Runner. You might notice a few things:
The Command Log now shows the new VISIT action.
The Kitchen Sink application has been loaded into the App Preview pane.
The test is green, even though we made no assertions.
The VISIT displays a blue pending state until the page finishes loading.

I would like to know if it would be too hard to implement the routine below with *.bat file on Windows:
1) detects when an input/textarea (on a Chrome browser) contains a certain word (like "word123")
2) fires a custom physical keypress on the keyboard so the key pressed gets displayed in the input/textarea where the caret is positioned.
This is a very specific use case in a hospital system where we need to detect some special words in medical record where doctors are typing in any page they are browsing.
One suggestion is to use something like AutoHotKey, which can certainly do the monitoring and simulate a physical key press. However, if you're triggering based on the word being entered, then the physical key press would happen right away (as soon as the '3' is released in your example). Agree that this isn't really a programming question yet - if you give AutoHotKey a try and run into issues, come back and post some code.

I need to create a simple app that allow user to drag and drop multiple files and folder into some tree list and then display them to user.
A good example of what I need:
What best component should I use?
I just want to take advice before I start.
Your question is too broad, but I'll point you the right direction:
• For your data model, you'll want to use NSTreeController
• For your view, NSOutlineView.
Here are some examples:
• Apple's SourceView - https://developer.apple.com/library/mac/samplecode/SourceView/Introduction/Intro.html

Is there any alternative short name for controller, I feel this very general word is a little long for typing.
I think people sometimes use Ctrl as a short hand for control, but this is often in the context of Controls like buttons and check boxes.
In MFC (and wxWidgets), they tend to call the Controller class the App, e.g. as in GraphicApp.

I develop a desktop application, and I'd like to add a "question mark" icon besides one of the textbox (that describes the meaning of that textbox).
My question is what's the common way to use the question mark:
Should I show the text when hovering on the question mark? e.g. using a tooltip?
Should I show the text just after clicking on the question mark?
Thank you!
I suggest you show the tooltip on hover. That is one click less for me as a user.
That aside another thing to consider while constructing a forms based user interface is to label the controls descriptively enough such that users don't need any further help beyond the component label. If the tooltip is your primary means of conveying the meaning of the control, you definitely have to rethink the form design. Basically don't use tooltips as an affordance, a placeholder with 2-3 words as additional description is a better first choice.
The only place where I see click to reveal tool-tips being really useful is in a touch interface.
