If your reason for using Python/Tkinter is to develop prototypes for applications, then the point is somewhat moot; you will develop prototypes quickly in Python/Tkinter. 3 How do I use Tkinter? Tkinter comprises a number of components. _tkinter, as mentioned before, is the low level interface to the Tk libraries and is linked into Python. 2 of Python, Tkinter, Tcl and Tk are part of the installation package—at least for the Win32 distribution. For several UNIX variants and Macintosh, it is still necessary to build Python to include Tkinter.

Once a version of Python has been built and _tkinter has been included, as a shared library, dll or statically linked, the Tkinter module needs to be imported. This imports any other necessary modules, such as Tkconstants. py”). pack() mainloop() 1 2 3 Code comments 1 First, we import components from the Tkinter module. By using from module import Label, mainloop we avoid having to reference the module to access attributes and methods contained in the module. 2 We create a Label containing two lines of text and use the Pack geometry manager to realize the widget.

The tuples store three labels, the key color, the function or key designator and the method to bind to the key’s cmd (activate) callback. - We create the Pmw ScrolledText widget and provide values for many of its attributes. ScrolledText(self, hscrollmode='dynamic', C AL CU LATO R E X A MP L E : S O U R C E C O DE 25 vscrollmode='dynamic', hull_relief='sunken', hull_background='gray40', hull_borderwidth=10, text_background='honeydew4', text_width=16, Notice how the attributes for the hull (the container for the subordinate widgets within Pmw widgets) and the text widget are accessed by prefixing the widget.
