Simple Question 1

[nickthegreek82]

Hello there!
I am new in TCL and Tk programming and i have a problem with my project i am on.
I have deactivated the resize icon in title bar of my application and i want to do the same with the "X" wich destroys the widget. Is it possible to do that ? If not i want to have a procedure executed when pressing the "X" in the title bar... can i do this ?
Any help will be highly appreciated.
Thanks in advance
Nick

look at the "[red]overridedirect[/red]" option of the wm (window management) command. From the help file:

wm overrideredirect window ?boolean?
If boolean is specified, it must have a proper boolean form and the override-redirect flag for window is set to that value. If boolean is not specified then 1 or 0 is returned to indicate whether or not the override-redirect flag is currently set for window. Setting the override-redirect flag for a window causes it to be ignored by the window manager; among other things, this means that the window will not be reparented from the root window into a decorative frame and the user will not be able to manipulate the window using the normal window manager mechanisms.

Hi

Theoretically, somehow like this :

bind . <Destroy> { puts "Bye !" }

Practically, the code is executed for each widget on that window. But there is a warning in the manual :

When the Destroy event is delivered to a widget, it is in a ``half-dead'' state: the widget still exists, but most operations on it will fail.

http://www.tcl.tk/man/tcl8.4/TkCmd/bind.htm#M16

With the above [tt]bind[/tt] I can close an open socket before exiting, but cannot save settings in a file. So I hope someone knows a better way.

Thanks my friend for your time.
I found another solution ...

wm protocol . WM_DELETE_WINDOW { procedure_name }

There are some limitations though to that procedure , i think you can not set any values to variables.

Hope this works for you as well!

I think a better (in the sense of more controllable and predictable) way would be to pull off all the decorations (with overrideredirect) and put your own "x-button" on with what ever -command you want.
