how to change NSCursor and effect on my application.

Question

Hi,

I have obtained the crosshair cursor from NSCursor crosshairCursor. Then, how can i change

to it. I don't want to call enclosingScrollView to setDocumentCursor as

[[view enclosingScrollView] setDocumentCursor:crosshaircursor ];

Answer 1

You just use the -set method of NSCursor to set the current cursor:

[[NSCursor crosshairCursor] set];

Answer 2

You can implement a resetCursorRects method to send yourself addCursorRect:cursor: mesasges. This way, the cursor will automatically change to the crosshair whenever it enters the appointed section of your view.
