# WXpython

|
||||
## wxpython helloworld
|
||||
|
||||
The absolute most basic way to have a *hello world* GUI program up and running with wxpython is the following.
|
||||
|
||||
```python
|
||||
import wx
|
||||
|
||||
app = wx.App()
|
||||
|
||||
frame = wx.Frame(None, title="hello world")
|
||||
|
||||
frame.Show()
|
||||
|
||||
app.MainLoop()
|
||||
```
|
||||
|
||||
While it works we know better by now.
|
||||
We should include the `if __name__ == "__main__"` statement.
|
||||
|
||||
```python
|
||||
import wx
|
||||
|
||||
|
||||
if __name__ == "__main__":
|
||||
app = wx.App()
|
||||
frame = wx.Frame(None, title="hello world")
|
||||
frame.Show()
|
||||
app.MainLoop()
|
||||
```
|
||||
|
||||
The instance of `wx.App` is what will actually process our event loop and the `wx.Frame` is the content of our window.
|
||||
In the latter we will create our button and labels so should create our own class and inherit from it.
|
||||
|
||||
```python
|
||||
import wx
|
||||
|
||||
|
||||
class MainWindow(wx.Frame):
|
||||
def __init__(self):
|
||||
wx.Frame.__init__(self, None, title="hello world")
|
||||
self.Show()
|
||||
|
||||
|
||||
if __name__ == "__main__":
|
||||
app = wx.App()
|
||||
win = MainWindow()
|
||||
app.MainLoop()
|
||||
```
|
||||
|
||||
We can add content to the *frame*, such as labels, input boxes and buttons as follows.
|
||||
Note the first argument to the `wx.StaticText` creation.
|
||||
This is *where* we put the label *into*.
|
||||
It kind of works but we'll encounter a **problem** when we pack more visual **objects** into the same frame.
|
||||
|
||||
```python
|
||||
import wx
|
||||
|
||||
|
||||
class MainWindow(wx.Frame):
|
||||
def __init__(self):
|
||||
wx.Frame.__init__(self, None, title="hello world")
|
||||
self.label = wx.StaticText(self, label="this is a label")
|
||||
self.Show()
|
||||
|
||||
|
||||
if __name__ == "__main__":
|
||||
app = wx.App()
|
||||
win = MainWindow()
|
||||
app.MainLoop()
|
||||
```
|
||||
|
||||
Let's try to put multiple visual object into the same frame.
|
||||
|
||||
```python
|
||||
import wx
|
||||
|
||||
|
||||
class MainWindow(wx.Frame):
|
||||
def __init__(self):
|
||||
wx.Frame.__init__(self, None, title="hello world")
|
||||
self.label = wx.StaticText(self, label="this is a label")
|
||||
self.input = wx.TextCtrl(self)
|
||||
self.button = wx.Button(self)
|
||||
self.Show()
|
||||
|
||||
|
||||
if __name__ == "__main__":
|
||||
app = wx.App()
|
||||
win = MainWindow()
|
||||
app.MainLoop()
|
||||
```
|
||||
|
||||
You see how they are *stacked* one on top of the other?
|
||||
We can overcome this problem with [sizers](https://wxpython.org/Phoenix/docs/html/sizers_overview.html).
|
||||
There are multiple ones we can use but let's dive into a first one called a **box sizer**.
|
||||
|
||||
```python
|
||||
import wx
|
||||
|
||||
|
||||
class MainWindow(wx.Frame):
|
||||
def __init__(self):
|
||||
wx.Frame.__init__(self, None, title="hello world")
|
||||
self.panel = wx.Panel(self)
|
||||
self.box = wx.BoxSizer()
|
||||
self.label = wx.StaticText(self.panel, label="this is a label")
|
||||
self.input = wx.TextCtrl(self.panel)
|
||||
self.button = wx.Button(self.panel, label="I'm clickable!")
|
||||
self.box.Add(self.label)
|
||||
self.box.Add(self.input)
|
||||
self.box.Add(self.button)
|
||||
self.panel.SetSizer(self.box)
|
||||
self.Show()
|
||||
|
||||
|
||||
if __name__ == "__main__":
|
||||
app = wx.App()
|
||||
win = MainWindow()
|
||||
app.MainLoop()
|
||||
```
|
||||
|
||||
This is looking better!
|
||||
But it requires some explanation though.
|
||||
Let's break it down.
|
||||
The `wx.Frame` is your **window** in which you create a `wx.Panel` which is used to draw thing to.
|
||||
To this panel you're adding three different *objects* (`wx.StaticText`, `wx.TextCtrl` and `wx.Button`) each with or without their own settings (such as a label or not).
|
||||
Next you add these three objects to the `wx.BoxSizer` and you tell the panel to use this box as sizer.
|
||||
It probably looks a bit convoluted but this is how most GUI libraries work internally.
|
||||
|
||||
1. You create a frame
|
||||
2. Within this frame you create a *drawing area* and set some form of automatic layout to it (the `wx.BoxSizer`).
|
||||
3. You create the visual elements you want and add them one by one to the drawing area.
|
||||
4. Success
|
||||
|
||||
Now how do we link **user input** to **code actions**?
|
||||
This is a complicated way of saying *actually do something when I click the damn button*!
|
||||
For this we'll need to create a function, or better yet a method to the `wx.Frame` objects.
|
||||
Each time we click the button, that method will be called.
|
||||
Because it is a *method* it has access to *self* so it can modify *anything* within the scope of the instance.
|
||||
|
||||
```python
|
||||
import wx
|
||||
import random
|
||||
|
||||
|
||||
class MainWindow(wx.Frame):
|
||||
def __init__(self):
|
||||
wx.Frame.__init__(self, None, title="hello world")
|
||||
self.panel = wx.Panel(self)
|
||||
self.box = wx.BoxSizer()
|
||||
self.label = wx.StaticText(self.panel, label="this is a label")
|
||||
self.input = wx.TextCtrl(self.panel)
|
||||
self.button = wx.Button(self.panel, label="I'm clickable!")
|
||||
self.button.Bind(wx.EVT_BUTTON, self.set_label_value)
|
||||
self.box.Add(self.label)
|
||||
self.box.Add(self.input)
|
||||
self.box.Add(self.button)
|
||||
self.panel.SetSizer(self.box)
|
||||
self.Show()
|
||||
|
||||
def set_label_value(self, event):
|
||||
number = random.randint(0, 100)
|
||||
self.label.SetLabel("{}".format(number))
|
||||
|
||||
|
||||
if __name__ == "__main__":
|
||||
app = wx.App()
|
||||
win = MainWindow()
|
||||
app.MainLoop()
|
||||
```
|
||||
|
||||
We can use the same *idea* to grab input from the textbox.
|
||||
|
||||
```python
|
||||
import wx
|
||||
|
||||
|
||||
class MainWindow(wx.Frame):
|
||||
def __init__(self):
|
||||
wx.Frame.__init__(self, None, title="hello world")
|
||||
self.panel = wx.Panel(self)
|
||||
self.box = wx.BoxSizer()
|
||||
self.label = wx.StaticText(self.panel, label="this is a label")
|
||||
self.input = wx.TextCtrl(self.panel)
|
||||
self.button = wx.Button(self.panel, label="I'm clickable!")
|
||||
self.button.Bind(wx.EVT_BUTTON, self.set_label_value)
|
||||
self.box.Add(self.label)
|
||||
self.box.Add(self.input)
|
||||
self.box.Add(self.button)
|
||||
self.panel.SetSizer(self.box)
|
||||
self.Show()
|
||||
|
||||
def set_label_value(self, event):
|
||||
msg = self.input.GetValue()
|
||||
self.label.SetLabel("{}".format(msg))
|
||||
|
||||
|
||||
if __name__ == "__main__":
|
||||
app = wx.App()
|
||||
win = MainWindow()
|
||||
app.MainLoop()
|
||||
```
|
||||
|
||||
## wxpython guess the number
|

```python

class MainWindow(wx.Frame):
|

def __init__(self):
|
||||
wx.Frame.__init__(self, None, title="Guess the number")
|
||||
self.number = random.randint(0, 100)
|
||||
self.panel = wx.Panel(self)
|

self.box = wx.BoxSizer(wx.VERTICAL)

## MVC design pattern
|
||||
|
||||
A simple console only MVC.
|
||||
We'll add the GUI view in a bit.
|
||||
|

```python

For a GUI only login generator an implementation without MVC could look a bit like this.
|
||||
Note that the actual calculation is done inside the window itself.
|
||||
This is not a good idea because we should separate responsibilities into classes!
|
||||
|
||||
```python

import wx
|

import login_generator

A clear separation of responsabilities can be acchieved via an MVC pattern and a login *library*.
|
||||
The library code is quite straightforward and goes as follows.
|
||||
It's basically the same code we did before but with added `try except` blocks.
|
||||
Can you tell me why I added those?
|
||||
|
||||
```python
|
||||
import random
|
||||
import string
|
||||
|
||||
|
||||
def load_file(filename):
|
||||
"""
|
||||
We load a file and make a list out of it. Note that the same function is
|
||||
used for both files (both adjectives and subjects). Functions should be
|
||||
made as generic as possible.
|
||||
|
||||
There IS a problem you can fix, some logins will have spaces in them. Try
|
||||
to remove them in this function!
|
||||
"""
|
||||
words = []
|
||||
with open(filename, "r") as fp:
|
||||
lines = fp.readlines()
|
||||
for line in lines:
|
||||
words.append(line.strip()) # what does strip() do, what does append() do? remember CTRL+Q!
|
||||
return words
|
||||
|
||||
|
||||
def generate_username():
|
||||
"""
|
||||

||||
"""
|
||||
try:
|
||||
adjectives = load_file("./adjectives.txt")
|

|

|
||||

|
||||
adjective = random.choice(adjectives)
|
||||
subject = random.choice(subjects)
|
||||
username = adjective.capitalize() + subject.capitalize()
|
||||
return username
|
||||
|
||||
|
||||
def generate_password(length=10, complictated=True):
|
||||
"""
|
||||

|
||||
changing the arguments in the function call.

if complictated:
|

|

# let's do some testing!

|
||||
print(username_test)
|
||||
password_test = generate_password()
|
||||
print(password_test)
|
||||
```
|
||||
|
||||
And now the GUI code nicely split up in a **model**, **controller** and a **view**.
|

The overhead is quite large but it makes the code a lot more scalable.
