Re: clearing edit controls

Thanks for the feedback everyone.

I see what I'm doing wrong. I'm trying to change the value of the edit control in the
event handler kEventTextShouldChangeInRange.

I overlooked the event handler's description:
"Returns whether the text should be changed in editable text fields." Doh!

Yes, reading documentation is such a waste of time until you waste even more writing code without understand what things do. ;-)

If you return noErr the text won't change. I believe that if you set different text and return eventNotHandledErr, the new text will be used instead of the original text.

Is there an appropiate event handler where I should be making my changes to the contents?

Or are the event handlers not appropiate for this?

Not generally appropriate. Could you be more specific about what you want to do? You're asking low level questions. Tell us what you want to accomplish.

I'm new to apple's event handler setup so any advice would be greatly appreciated.

thanks,

The space was just one of the ways I've tried. I've also tried ("").

Is there a better way?

err = HIViewSetText( view, CFSTR( "" ) );

works on my setup -- nib: com.apple.HITextField, Xcode 3.0, Max OS X 10.5.2.
