**[`wxPython`][wxpy]** is a cross-platform GUI toolkit implementation of **[`wxWidget`][wxw]** for the Python language to create truly native user interfaces applications.
|
||
|
||
## wxPython installation
|
||
|
||
* `sudo apt install build-essential dpkg-dev freeglut3-dev libasound2-doc libgstreamer1.0-dev libgtk-3-dev libjpeg-dev liblzma-doc libnotify-dev libsdl1.2-dev libsm-dev libtiff-dev libwxgtk3.0-gtk3-dev libwxgtk-webview3.0-gtk3-dev libxtst-dev python3.7-dev`
|
||
* `virtualenv --python python3.7 .venv`
|
||
* `source .venv/bin/activate`
|
||
* `pip install wxPython --build ~/tmp`
|
||
|
||
## `HelloWorld` [source][wiki-wxpy]
|
||
|
||
```python
|
||
#!/usr/bin/env python3
|
||
# coding:utf-8
|
||
import wx
|
||
|
||
# Création d'un nouveau cadre, dérivé du wxPython 'Frame'.
|
||
class TestFrame(wx.Frame):
|
||
def __init__(self, parent, ID, title):
|
||
wx.Frame.__init__(self, parent, -1, title, pos=(-1, -1), size=(200, 100))
|
||
|
||
# À l'intérieur du cadre, créer un panneau..
|
||
panel = wx.Panel(self, -1)
|
||
|
||
# Créer un texte dans le panneau
|
||
texte = wx.StaticText(panel, -1, "Bonjour tout le monde!", wx.Point(10, 5), wx.Size(-1, -1))
|
||
|
||
# Créer un bouton dans le panneau
|
||
bouton = wx.Button(panel, -1, "Cliquez-moi!", wx.Point(10, 35), wx.Size(-1, -1))
|
||
# lier le bouton à une fonction:
|
||
self.Bind(wx.EVT_BUTTON, self.creerDiag, bouton)
|
||
|
||
# fonction qui affiche une boîte de dialogue
|
||
def creerDiag(self, event):
|
||
dlg = wx.MessageDialog(self, "Merci de m'avoir cliqué, ça fait du bien.",
|
||
"Merci!", wx.ICON_EXCLAMATION | wx.YES_NO | wx.CANCEL)
|
||
dlg.ShowModal()
|
||
dlg.Destroy()
|
||
|
||
|
||
# Chaque application wxWidgets doit avoir une classe dérivée de wx.App
|
||
class TestApp(wx.App):
|
||
def OnInit(self):
|
||
frame = TestFrame(None, -1, "Test")
|
||
self.SetTopWindow(frame)
|
||
frame.Show(True)
|
||
return True
|
||
|
||
if __name__ == '__main__':
|
||
app = TestApp(0)
|
||
app.MainLoop()
|
||
```
|
||
|

### Tadaaa !

Notes :
|
||
-------
|
||
|
||
* I had troubles with `python3.6` (but I forgot notice what…)
|
||
* About 4.2G of free space is needed in `/tmp` : [I had to set a user-land build-place for pip][pip]
