can I change the cursor to wait cursor?

[shyam]

Hi,

I'm developing an application using Cocoa/Objective-C. During some opeartion I need to change the cursor to "wait cursor" so that the user cannot do any other operation that time. The system is not changing the cursor automatically to a wait cursor. Can I do it explicitly by writing some code? If that is not possible, then what is the way out to restrict the user to do any other operation that time.

Thanks,

Shyam

If you don't want the user to do something like click a button, before
starting the task, just disable it and any other control [myControl
setEnabled:NO]; and once finished just reenable it.

HTH,

Thanks for your response. I cannot disable everything. In my application, I have a NSBrowser. I cannot prevent the user clicking on it. So what all I need to do is that to change the cursor style "busy". Is there any method in Cocoa/Objective-c to do that?

Thx,
Shyam

There is no method to do that, but there is a function in the
ApplicationServices framework

QDDisplayWaitCursor(Boolean forceWaitCursor);

Call it with true to display the busy cursor, and call it again with
false to reset the cursor.
