Project description


PyPI version

PySide2 configuration in yaml format providing the most simple script.


  • yaml
  • PySide2


cd <path-to-ReadableWidgets>/PyamlSide2
pip install .


python3 examples/


1. create drawio-xml


Put the Rounded Rectangle and add text.


| widget:unique-label |


  • widget : widget name pushbutton, label, ...
  • unique-label : Unique label (also treated as a Key in Python).

Don't use compression flag. (Please uncheck.)

2. 🏁 drawio-xml -> YAML & Python (simple conversion)

rw_gen_xml2all -i <input .xml> -o <output directory>

2-1. Generate YAML file from drawio-xml

Although it is possible to convert directly from drawio-xml, conversion to YAML is recommended for readability.

rw_gen_xml2yaml -i <input .xml> -o <output .yaml>

2-2. Generate Python file from YAML

Create a sample Python program from a YAML file.

rw_gen_yaml2py -i <input .yaml> -o <output .py>

3. Run example python template

python3 <output .py (3rd step)> <input .yaml (3rd step)>


Previously (v0.3.2)

See examples/

import sys
import os

from pyamlside2.mainwindow import PyamlSide2Window
from PySide2.QtWidgets import QApplication

class MainWindow(pyamlside2Window):
    def __init__(self):
        self.number = 0
        yaml_path = os.path.join(os.path.dirname(__file__), "../yaml/chaos.yaml")
        # your code -------------------------
        # ************ #
        # -----------------------------------

if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = MainWindow()

Test YAML 📝

pyamlside2_yaml is preview feature app.

pyamlside2_yaml <yaml-file-path or xml-file>
# pyamlside2_yaml PySide2/drawio_xml/example.xml

Elements (dev)

In yaml, you can add the following elements defined in PyQt.Widgets This may be added in the future.

  • pushbutton : definition of QPushButton
  • qlabel : definition of QLabel
  • qlcdnumber : definition of QLCDNumber
  • qprogressbar : definition of QProgressBar
  • qlineedit : definition of QLineEdit
  • qcheckbox : definition of QCheckbox
  • qslider : definition of QSlider
  • qspinbox : definition of QSpinBox
  • qcombobox : definition of QCombobox
  • image : definition of QLabel (using image path)
  • stylesheet : definition of Stylesheet (define as QLabel and setHidden=True)

YAML format

PyamlQt defines common elements for simplicity. Not all values need to be defined, but if not set, default values will be applied

WINDOW: # unique key (Define key)
  type: window
  x: 0
  y: 0
  width: 800
  height: 720
  title: "example"

slider2: # keyname
  type: qslider # QWidgets
  x_center: 500 # x center point
  y_center: 550 # y center point
    width: 200 # QWidgets width
    height: 50 # QWidgets height
  max: 100 # QObject max value
  min: 0 # QObject min value
  default: 70 # QObject set default value
  text: "Slider" # Set Text
  style: # Setting style using stylesheet (css)
    font: 30px # font size
    color: #ff0000 # Color
    font-family: Ubuntu # font-family
  items: # Selectable items( Combobox's option )
    - a
    - b
    - c
