In this wxPython article we want to learn about How to Build Responsive GUI with wxPython, Graphical User Interfaces (GUI) is an important part of modern software development. because they provide an easy way for users to interact with software and makes the user experience very good. if you are Python developer and looking to build responsive GUI for your applications, than wxPython is an excellent framework to consider. in this article we want to talk about the e steps to build responsive GUI with wxPython,, but first of all let’s talk about wxPython.
What is wxPython ?
wxPython is cross platform GUI library for the Python programming language. it allows developers to create native looking and professional GUI applications that run on Windows, macOS and Linux. wxPython is built on top of wxWidgets C++ library, which provides a lot of native looking widgets that you can use in your GUI applications.
How to Build Responsive GUI with wxPython
For building GUI applications with wxPython, first we need to install this library and we can use pip for that.
|
1 |
pip install wxPython |
next step is to create wxPython application. this is done by creating an instance of the wx.App class. this class represents the entire application and is responsible for managing the main event loop.
|
1 2 3 |
import wx app = wx.App() |
Now we need to create our frame, frame is the main window of the GUI application. it contains all other widgets and controls of the application. you can create a frame by subclassing wx.Frame class.
|
1 2 3 4 |
class MyFrame(wx.Frame): def __init__(self): super().__init__(None, title="Geekscoders.com", size=(400, 300)) self.Show() |
After that you have created frame, you can add widgets and controls to it. wxPython provides different widgets and controls including buttons, labels, text boxes and many more. this is an example of how to add a button to the frame.
|
1 2 3 4 5 6 7 8 9 10 11 |
class MyFrame(wx.Frame): def __init__(self): super().__init__(None, title="Geekscoders.com", size=(400, 300)) btn = wx.Button(self, label="Click me") self.Bind(wx.EVT_BUTTON, self.on_button_click, btn) self.Show() def on_button_click(self, event): print("Button clicked!") |
Once you have added the widgets and controls to the frame, you need to add layout, because we want that the widgets appears correctly on the screen. wxPython provides several layout managers to help with this task, including wx.BoxSizer, wx.GridSizer and wx.FlexGridSizer. this is an example of how to use the wx.BoxSizer to layout the button.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
class MyFrame(wx.Frame): def __init__(self): super().__init__(None, title="Geekscoders.com", size=(400, 300)) btn = wx.Button(self, label="Click me") self.Bind(wx.EVT_BUTTON, self.on_button_click, btn) sizer = wx.BoxSizer(wx.HORIZONTAL) sizer.Add(btn, 0, wx.ALL, 10) self.SetSizer(sizer) self.Show() def on_button_click(self, event): print("Button clicked!") |
So now we have completed all the steps, now we can run the application. this is done by calling MainLoop() method of the wx.App class, this will be our complete code.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
import wx class MyFrame(wx.Frame): def __init__(self): super().__init__(None, title="Geekscoders.com", size=(400, 300)) btn = wx.Button(self, label="Click me") self.Bind(wx.EVT_BUTTON, self.on_button_click, btn) sizer = wx.BoxSizer(wx.HORIZONTAL) sizer.Add(btn, 0, wx.ALL, 10) self.SetSizer(sizer) self.Show() def on_button_click(self, event): print("Button clicked") app = wx.App() frame = MyFrame() app.MainLoop() |
Run the code and this will be the result
