wxPython window

wxPython is a GUI toolkit for the Python programming language. With wxPython, developers can create highly interactive and user-friendly graphical user interfaces (GUI).
This GUI toolkit offers a native appearance on all platforms, ensuring that applications appear as native applications. This is in contrast to other toolkits like QT or Tk, which might have a custom look. Moreover, wxPython provides cross-platform support, making it functional across all major desktop platforms.
Notably, the supported operating systems include Microsoft Windows (32-bit), most Unix or unix-like systems, and Macintosh OS X.
For those interested in diving deeper into creating GUIs with this toolkit, there’s a related course available on the subject.
Fundamentally, the wxPython module is constructed upon the C++ GUI library, wxWidgets.

Creating a wxPython window

Initiating a window using wxPython is straightforward. Here’s how you can open a basic window:

#!/usr/bin/python

import wx      
app = wx.App()
frame = wx.Frame(None, -1, 'win.py')
frame.Show()
app.MainLoop()

The function wx.App() is responsible for creating an application object. It’s vital to note that every wxPython program requires at least one .App() object.
Subsequently, the method wx.Frame() is invoked to generate a new window which can accommodate various widgets.
Lastly, the app.MainLoop() ensures that the application remains in the main loop, thereby listening and responding to different events.

Adjusting Window Size and Position

If you need to modify the size or position of your window, the SetDimensions() function is your go-to:

#!/usr/bin/python

import wx

app = wx.App()
frame = wx.Frame(None, -1, 'win.py')
frame.SetDimensions(0,0,640,480)
frame.Show()
app.MainLoop()

The function accepts parameters for x (left position), y (top position), width, and height. Aside from adjusting the screen resolution, it also determines the window’s position on the screen.

Centering the Window

To effortlessly center the window on your screen, you can simply use:

frame.Centre()
