Is there any way that I can write a GIMP add-in that can obtain the coordinates of user mouse clicks in the main GIMP image window? My add-in needs the user to be able to click on specific locations within the main image window in order to obtain various coordinates for subsequent processing.

No, there isn't. All you can do is to show a representation of the image in the plug-in dialog and have the user click there.

I have another question - is it possible through settings to make GIMP to display the size of rectangular selection, excluding non-image area? Current realization displays the size of the whole selection, even if the part of the selection is outside image boundaries.

If it's impossible, should I fill an issue?

Sven, you're the guru, so you would know. However, how is it that I can't get the coordinates, when apparantly something like the crop tool can? Is the crop tool specially written using internal gimp facilities that aren't available to a normal add-in?

Would you mind to define "normal add-in" then? I assumed you meant a plug-in and the crop tool, like all other tools, is completely implemented in the core.

The selection cannot extend the image boundaries. This is a bug in the rectangular selection tool then.

This is the difference between a tool and a plug-in. A tool is something which (usually) operates locally on the basis of a mouse click (the colour tools are the exceptions, which often causes some confusion). A plug-in usually gets a copy of a drawable to work on, and doesn't have access to things like mouse click events which are captured and treated in the core.

Cheers, Dave.

Ok, I've posted a bug.
