I am new to Cocoa/Objective-C and new to the forum, so apologies if
this is a newbie questions.
I am trying to use NSAppleScript from Objective-C to execute the
following one liner, and covert the result into an NSRect:
"Tell application \"Finder\" to return (bounds of window of desktop)"
When I call the compileAndReturnError method of NSAppleScript it
crashes the debugger. I also am not sure how to actually access the
result of the NSAppleScript call once I get the script to run.
I would be grateful if someone can offer advice and/or a pointer in
the right direction to getting this to work.
I have no idea how you are managing to "crash the debugger" with this
code. I also don't understand why you are using AppleScript to get the
dimensions of the desktop. You should be using the Cocoa NSScreen
class if you want to find out screen dimensions.
Here is one way that you could get the bounds using AppleScript from
the Finder using your source. Note that I have done no sanity checking
of the NSAppleEventDescriptor that is returned:
NSAppleScript* script=[[NSAppleScript alloc] initWithSource:@"tell
application \"Finder\" to return (bounds of window of desktop)"];
NSDictionary* scriptError=nil;
NSAppleEventDescriptor* descriptor=[script
executeAndReturnError:&scriptError];
if(scriptError)
{
NSLog(@"Error: %@",scriptError);
return;
}
//note that this does not return an origin in Cocoa base coordinates
for multiple-monitor systems
NSLog(@"Desktop frame: %@",NSStringFromRect(desktopFrame));
Here is how you would find out the size of the desktop using the
NSScreen class, which will be much faster and more reliable, as well
as returning a result in Cocoa base coordinates:
