Hi,

After my graphical output is shown by gkshow,
I would like to click on it and getting the x and y coordinates
of the mouse pointer.

I can't find how to do.
Is it really possible and how ?

Thanks you
Regards

That is not yet implemented. As I probably need this soon myself, there is a good chance that I implement it soon
Or maybe, if you know C you could give me a hand?

I'm not a C expert but, of course, if I can help you
I'll do what I can.

The idea would be to implement a GtkEventBox which then will be the container for the image (or anything else). This is (according to the docs) necessary, as a GtkImage does not have its own window and thus cannot receive any signals.

I am still not sure how to implement the signals in a fortran-like style. I want to avoid callback functions (they might also create problems with certain compiler combinations), so we would either need an (ugly) polling mechanism or some 'magic' variables like the iclos argument of gkwindow (which will be in fact implemented by a hidden C callback function, similar to gkcbset).

What do you think?

The problem is, if I can program in C relatively complete things
I know nothing about Gtk and writing C/Fortran90 interfaces.

I need time to learn about Gtk and signals.
I'll begin next week when I have time.
