Hello

I'm newbie here and I'm still learning tcl/tk and I have problem with bind function in hypermesh. 

I would like to run a function when the user clicks the left mouse button. For example I want to read position of pointer.

I'm using bind function: 


 bind . <Button-1> {myProc}

 

The problem is that it doesn't work when I click mouse button in graphic area.  It works fine when I click toolbars or tab areas, but I want to run my function if I click anywhere in HM window.

Instead of Button-1 I can use space button in my bind function:


 bind . <Key-space> {myProc}

 

It works well but it's pointless and you have to use keyboard.

Any idea or suggestions how to deal with this?

 

Thanks a lot for help

 

Regards

    Hi, 

    graphic area belongs to core application and has it own binding (ex: to select elements, nodes,.. by mouse)

    should not (and may not be able to) add binding to it

    key binding also should be assigned via hypermesh, not directly by tcl-tk (menu Preferences/Keyboard Settings)

    whenever you want to get pointer position you can use winfo command:

    set x [winfo pointerx .]

    set y [winfo pointery .]

     

    assign binding directly just should be done for local window (not root window . )
