This article mainly explains "how to write a gadget with wxPython". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to write a gadget with wxPython.

Used to open frequently used websites, after the program starts, the interface looks like this

Program code configuration file

Create a new file called config.py with the following contents

# coding=utf-8

Urlconfig = {

U 'Baidu': 'http://www.baidu.com',

Ubiquitous CSDN http://www.csdn.net',

U 'rookie world': 'http://www.zhangdongshengtech.com'

}

Main program

Create a new file named browser.py in the same directory with the following contents

# coding=utf-8

Import wx

Import os

From config import urlconfig

Def clickbtn (event):

Namelist = cl.GetCheckedStrings ()

# Open the URL

For name in namelist:

Command = "explorer {url}" .format (

Url=urlconfig [name])

Os.system (command)

# uncheck

Checkindex = cl.GetChecked ()

For index in checkindex:

Cl.Check (index, False)

App = wx.App ()

Window = wx.Frame (None

Title=u "first Program", size= (350,400))

Panel = wx.Panel (window)

B = wx.Button (panel, 10, u "open", (200,20))

Panel.Bind (wx.EVT_BUTTON, clickbtn, b)

UrlList = urlconfig.keys ()

Cl = wx.CheckListBox (panel

-1, (20,20), (150,300), urlList)

Window.Show (True)

App.MainLoop ()

Introduction of program interpretation control

Frame is a window control

Button is a button control

CheckListBox is a set of selection boxes, which are the controls you see on the left side of the image above. You can choose either one or multiple selections.

Control relationship

When each control is created, it must indicate who its parent control is, so that the controls are stacked layer by layer.

Event binding

Panel.Bind (wx.EVT_BUTTON, clickbtn, b) binds an event to the button control and executes the clickbtn function when the button is clicked

Clickbtn function

In the clickbtn function, the GetCheckedStrings method returns the string of the selected option, which is what can be seen on the interface. The option allows multiple selections, and the return value of the method is a tuple.

The GetChecked method returns the index number of the selected option, and the return value is also a tuple,GetCheckedStrings method and the GetChecked method actually return the information of the selected option, one is the index number, the other is the name string, it is reasonable to provide a function to return the two information at the same time, but I have not found the method yet.

The Check method sets the selected state of the option. The first parameter is the index number of the option, and the second parameter is the selected state. After each URL is opened, the previous selected state should be unchecked. Therefore, I set all the selected options to False.
