Book inventory plays an important key business data for warehouse management operations in books. Development at any age now promotes blood circulation in books, book types and update speed are just as fast rising.In order to ensure a foothold in the book industry, to ensure the correct purchase and inventory control and delivery. In order to avoid the backlog of

Drop ~ Today. Before touching a bit of tkinter, GUI programming a little interest, so on their own thinking to write a small program (haha, too small can not be small program). Well, after all, it's all about the automated tests, so it's a matter of having an automated test. In last week's blogger's notes, there was a solution to the validation code encountered when writing an automated logon script. Before we mentioned four solutions, let's review:

stipple= "gray25". has no effect unless the fill have been set to some color. See section 4.7, "Bitmaps". Tags The tags to is associated with the object, as a sequence of strings. See section 6.1.4, "Canvas tags". Width The Width of the border around the outside of the ellipse. Default is 1 pixel; See sections 4.1, "Dimensions" for possible values. If you set this to zero, the border is not appear. If you set this to zero and make the fill transparent

This paper is mainly based on colorsys implementation, the sample is from HLS to RGB, if you want to change the color space is very easy to modify only a function, the specific content is as follows Scale and canvas components are used. Run: The code is as follows: from Tkinter import * Import Colorsys #操作后的响应函数 def update (* args): ' color ' r,g,b = Colorsys.hl S_to_rgb (H.get ()/255.0, L.get ()/255.0, S.get ()/255.0) R,g,b = R * 255, G * 255, B *

The module ("Tk interface") isInterface of the standard Tk GUI toolkit. Tk andIt can be used on most Unix platforms, It can also be applied in Windows and Macintosh systems. Later versions of Tk8.0 can implement local window styles and run well on most platforms. Is a Python module with Tk interfaces,Library provides interfaces for Tk APIs, It belongs to the GUI tool group of Tcl/Tk. Tcl/Tk is a writing and graphics device developed by John Ousterhout. Tcl (tool command language) is a macro
