Call a function after the user has selected something in the schematic editor

PatrikOsgnach

Hello,

I have a simple matter to solve. I would like to have a function called when the user selects something in the schematic editor.
In particular, whenever the user click on a wire, I'd like to call a function f(wire) that does something with the wire label.

How can I do this? I didn't find anything suitable in the function trigger names table.

BTW, is it possible to have a function called when the user closes a tab or clicks on edit->hierarchy->return menu item?

Thank you.

    Hello Lawrence,

    thank you, I'll try your solution.

    Essentially I have to do two things:

    1) keep track of a "descent hierarchy". When the user opens the first schematic, push the cell name on a stack. When the user descends into a subcell with the descend command (which opens the cell in a new tab or in the current one), push the name of the cell on the stack. When the user returns (with the return command, with Ctrl+E or by closing the tab), pop the last cell name from the stack.

    I have solved this by using the deRegUserTrigger function to call a function when the schematic editor is opened. If the current cell name is already in the second-from-top position on the stack, it means that the user has returned and I'll just pop the top of the stack. Otherwise, I push the cell name. It works fine, but I was wondering if there is a cleaner solution.

    2) I need to keep an history of clicked wires names (click alone, not click and drag). When the user click on a wire, add the name to the list. When there are 2 names on the list, do some processing and the do what would have been done after an ordinary click

    Best regards,

    Patrik
