Pygubu is a RAD tool to enable quick and easy development of user interfaces for the Python's tkinter module.
The user interfaces designed are saved as XML files, and, by using the pygubu builder, these can be loaded by applications dynamically as needed.
Pygubu is inspired by Glade.
The latest version of pygubu requires Python >= 3.6
You can install pygubu using pip:
pip install pygubu
Since version 0.10 the project was splitted in two main modules:
- The pygubu core (this project), that load and build user interfaces defined in xml.
- The interface editor pygubu-designer, that helps you create the xml definition graphically.
Start creating your tkinter application xml UI definition using the pygubu-designer editor.
The following is a UI definition example called helloworld.ui:
<?xml version='1.0' encoding='utf-8'?>
<interface version="1.2">
<object class="tk.Toplevel" id="mainwindow">
<property name="height">200</property>
<property name="resizable">both</property>
<property name="title" translatable="yes">Hello World App</property>
<property name="width">200</property>
<child>
<object class="ttk.Frame" id="mainframe">
<property name="height">200</property>
<property name="padding">20</property>
<property name="width">200</property>
<layout manager="pack">
<property name="expand">true</property>
<property name="side">top</property>
</layout>
<child>
<object class="ttk.Label" id="label1">
<property name="anchor">center</property>
<property name="font">Helvetica 26</property>
<property name="foreground">#0000b8</property>
<property name="text" translatable="yes">Hello World !</property>
<layout manager="pack">
<property name="side">top</property>
</layout>
</object>
</child>
</object>
</child>
</object>
</interface>Then, you should create your application script as shown below (helloworld.py):
# helloworld.py
import pathlib
import tkinter as tk
import tkinter.ttk as ttk
import pygubu
PROJECT_PATH = pathlib.Path(__file__).parent
PROJECT_UI = PROJECT_PATH / "helloworld.ui"
class HelloworldApp:
def __init__(self, master=None):
# 1: Create a builder and setup resources path (if you have images)
self.builder = builder = pygubu.Builder()
builder.add_resource_path(PROJECT_PATH)
# 2: Load a ui file
builder.add_from_file(PROJECT_UI)
# 3: Create the mainwindow
self.mainwindow = builder.get_object('mainwindow', master)
# 4: Connect callbacks
builder.connect_callbacks(self)
def run(self):
self.mainwindow.mainloop()
if __name__ == '__main__':
app = HelloworldApp()
app.run()Note: instead of helloworld.ui, you should insert the filename (or full path) of your UI definition:
PROJECT_UI = PROJECT_PATH / "helloworld.ui"Note: instead of 'mainwindow', you should have the name of your main_widget (the parent of all widgets) in the following line:
self.mainwindow = builder.get_object('_your_main_widget_')Visit the pygubu wiki for more documentation.
