How do I set an ImageWell in Xcode Cocoa-Applescript?

The business end of an image well is an NSImageView - the various class references usually have links in the Interface Editor's Quick Help inspector.

The method you are looking for is setImage, but since it uses an NSImage, you will need to create one first by allocating and intitializing it. Assuming that your image well outlet is named myImageWell, you can do something like the following:

set theImage to current application's NSImage's alloc's initWithContentsOfFile_("/path/to/Image.png") myImageWell's setImage_(theImage)

For future reference, you might want to trim your tag list a bit to those relevant to the particular topic. There are also Developer and OS X Technologies communities that have a more relevant audience for these kinds of topics.

There isn't much more to it than that. Are you getting an error message in the debug console? Is your outlet property connected to the image well? What do you have so far?

OK - when using the Interface Editor, you need to include outlet properties in your script that will represent the instances of the various UI objects. The Interface Editor will look for properties that have a specific signature, so the first thing is to add an outlet property to your script, set to missing value - for example:

property myImageWell : missing value

Once you have added (and saved) your script with the property, it will show up in the Interface Editor. The easiest way to start with would be to select the blue cube that represents your App Delegate, and look in the Connections Inspector to see all of the various connections - you should see the myImageWell property under Outlets. In the Inspector pane, there are connector symbols along the right side - click and drag a connection from the symbol for the myImageWell property to the image well in your user interface. Save the file and you are done - the actual propery values will be set when your application starts up.

That is the general procedure to connect things in your UI to the properties that represent them in your script (there are other goodies such as bindings, but this will get you started). Once connected, you can use the various methods of whatever class your object is an instance of (in this case an image well / NSImageView and its parents).

If the path to your file is not correct the image will be blank, but there will not be an error in the console - are you using the right (POSIX) file path?

Not sure why you are having problems, but I created a sample project for comparison - it can be downloaded here.
