I'm using a NSAlert to ask the user to enable Accessibility for assistive devices. Is it possible to have a button that does not close the NSAlert that I could use to just open the UniversalAccess prefpane ?
If not, I suppose I've to create myself that window.
Thx.
Normally alerts close when any button is pressed. In Mac OS X 10.5 or later you can use setAccessoryView: to insert a custom view into the alert, which presumably can contain a button that does anything you want.
Note however that you can't specify where the accessory view goes. It might have a button in it but the button would show up in the middle of the window instead of along the bottom with the other buttons. (If you chose a different button style such as a square bevel for your custom button, it might look less out of place.) To have complete control over layout, you need to make your own alert window.

I've created an interface nib/xib file. The app is basically working, which is cool. The standard toolbar buttons look bad, they're glossy and raised, while most apps in Lion have the flat, inner bevel look. So I created some image toolbar buttons and put them in the toolbar and they look great, but they're all disabled by default.
Is there a way to give these the correct state in InterfaceBuilder or do I have to use code to give them the proper state.
Cocoa and Objective C are very unfamiliar so it would be helpful to me if I just knew what to search for. Most of my searching brings me results for creating custom buttons for iOS.
I figured this out, here's what you do:
In the nib/xib file, double click your menu bar to show the "allowed toolbar items" sheet. From here, choose your button that you've created. In my case I'll select a back button that I want to connect to a webview control. Ctrl click + drag from the button to what you want to connect it to and then make the appropriate connection. In my case I choose goBack from the WebView.
Once it has a connection it now becomes active.
I am developing a cocoa application for mac. I have created a preference window with four buttons in toolbar. I am loading views on click event of buttons. Its working fine.
What I want to know is how to load another view on click of button in a view. Like in preference window of Safari, there is tab named with Privacy. And there is a button 'Details...' in Privacy tab. When we click on that button it shows a new view which shows a list of cookies.
Any Idea how to load view like view loaded on click of 'Details...' button???
There are several approaches, depending on what you're trying to accomplish. The easiest is probably to create the view you want, but make it hidden when you don't want it to be visible. Then when the user presses the "Details…" button, make it visible (and possibly expand the window if necessary) by calling [-NSView setHidden:NO].
Another way is to make the view a separate view in your .nib file, and when the "Details…" button is pressed, insert the view into the appropriate window using [-NSView addSubView:].
You could also create the view at runtime when the user presses the "Details…" button. That seems like a lot of work, though.
I am using SketchFlow for a prototype. Right now when the user clicks certain 'links' a trigger is excuted which calls navigatetoscreenaction and I supply the target screen. The problem is instead of going to this screen and leaving my main window, I want my target screen to popup into a modal dialog. Can you accomplish this with Sketchflow?
Yes, but you might have to code it up yourself. If you truly want a dialog you will have to do it in the event handler for the item you are clicking. You would do it just like any other dialog on the platform you are using.
If you just want to simulate it, you could make the screen into a component screen and use visual states to hide/show it. Made it hidden in the base state, and create a show state that you trigger with a behavior.
yes you sure can, with a component screen. Right click on your source screen in the sketchflow map and there it is.
Simple question:
How do I detect that the onscreen keyboard has been displayed on windows mobile 7? Is there an event I can add a listener to?
It takes up about half the screen and I want to scroll the view up when it gets displayed...
EDIT:
A comment below indicates more clearly what I'm trying to do: I have a textbox input, and as the user types into it an autocomplete dropdown appears below it (like google suggest). By default, the active control (the textbox) scrolls into view when focussed, and the onscreen keyboard is directly below it. The onscreen keyboard appears in front of my autocomplete dropdown - what I want to do is make the screen scroll a little further up, so there's some room for my dropdown to be shown.
The windows phone UI design guidelines say: "When the keyboard is deployed, the application should scroll to ensure the active edit control and the caret are in view". This happens fine, it's just the non-active dropdown gets hidden behind the onscreen keyboard.
The guidelines also say that an application can choose to show the onscreen keyboard, and can also choose to close it.
At the moment i'm stuck, and I don't think (based on my research and the replies to this question) that it's possible to detect that the onscreen keyboard has been displayed. I'm moving my investigation to see if it's possible to determine the "visible area" of the page (width & height in pixels for example), and combine this with an onfocus for the textbox... not sure if this will prove fruitful though.
Detecting when the virtual keyboard is displayed won't be possible in 7.0, as confirmed by Microsoft's Peter Torr in the WP7 forum on MSDN.
Maybe, as a dirty workaround, you could detect when the position of your text box (or its parent scroll viewer's offset) has changed, as this would indicate that the virtual keyboard has appeared or disappeared.
You can listen to the TextBox.GotFocus and TextBox.LostFocus events to detect when a text box in your application acquires and looses focus.
If an editable element gets focus then the framework will automatically scroll the element into view. So you really shouldn't have to do anything.
I am trying to interface with a cocoa popup menu from an OpenGL button. The actual button needs to be in OpenGL and I cannot stick an actual Cocoa button in its place but when this button is pressed I would like for a Cocoa menu to popup just like the one that comes up when you press the nspopupbutton. It seems that there is no way to get this popup window to come up by itself so I wanted to just insert an invisible button and have it be pressed automatically when the popup menu method is called. Is there a way to programmatically set a button to pressed (this will bring up the menu from the popupbutton) and make the button itself invisible without making the resulting menu invisible?
It seems that there is no way to get this popup window to come up by itself
Sure there is. See + popUpContextMenu:withEvent:forView:
Have you thought about just using a regular NSMenu, rather than trying to finagle the menu from an NSPopupButton?
