The TopLevel (top-level window) component is similar to a frame component, but the TopLevel component is a stand-alone top-level window that usually has parts such as title bars, borders, and so on, and is the same as the root window created by TK (), sharing the same method. When to use the TopLevel component. TopLevel components are typically used to display additional windows, dialogs, or other pop-up windows. In the following example, we add a button to the root window to create a top-leve

What is layout Manager: Managing how our components are arranged Tkinter provides us with three layout managers: Pack, grid, and place Packs, grid, and place are used to manage the layout of all components that are under a parent component, where: Pack is to arrange components in the order they are added Grid is the arrangement of components by row and column Place allows the programmer to specify the size and location of the component When to use t

coordinates, which defines the width (in pixel units) for each column. Event.x/y can take the coordinates. You can analyze the coordinate range of the column in which the coordinate falls.Header_widths=[n1,n2,n3 ....] row_selected = Your_treeview.identify_row (event.y) values = Your_treeview.item (row_selected, ' values ') Cell_val = Falseindex = -1t=event.xfor i in range (header_widths): if t>0: t=t-self.form_bom_line_widths[i] else: index=i-1 breakif index!=-1: c

You want to make a simple Python script editor where the text input Code section is implemented using the text control in Tkinter.But the question is, how do you achieve highlighting? Refer to Python's own editor: code in the Python27/vidle folder.The implementation effect Is:One of the main ideas is that in text every input line of code, all through regular matching, to find whether it is necessary to highlight the effect, the reason is very simple,

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:

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 Ousterh

messages (message) Message controls provide a way to display multiple lines of text, and you can set the font and background colorsExample: From tkinter Import * root=tk () root.title ("top") message (root,text= ' Your can record your wonderful-thing, Can record your wonderful thing ', \ bg= ' Blue ', fg= ' ivory ', Relief=groove).
