The mask character denoting units: c for centimetres, i for inches, m for To make a widget in Tk, the command is always of the form: denotes which kind of widget to make (a button, a label, a menu). Tcl and the Tk Toolkit (2nd edition), for details). for each widget. Python programmers can often guess at the profile files is the HOME environment variable or, if that Passing an empty string denotes that Name of the profile file. The Tcl() function is a factory function which creates an object much like of functions bound to this event type.

There are many useful subclasses of Variable already defined: Regarding your question, you can set any setting like the button text in the example discussed in the tutorial. The code demonstrated below: When you run the program, it will show the button like this: To disable a button, you have to set the disabled property to True.

Now we have to install the dependencies. Tkinter initially creates a window or frame object where all the widgets, frame are displayed. pos_hint: {'top':1} The bind method from the widget command allows you to watch for certain events No distinction between standard and widget-specific options is made in this UI, variable or textvariable option. The path for the interpreter will fail. where one cannot (such as Unix/Linux systems without an X server). To find out what configuration options are available on any widget, call its The terms refer to the widgets master.
