import sys
import os

from pyamlqt.create_widgets import create_widgets
import pyamlqt.qt6_switch as qt6_switch

qt6_mode = qt6_switch.qt6

if qt6_mode:
    from PyQt6.QtWidgets import QApplication, QMainWindow
else:
    from PyQt5.QtWidgets import QApplication, QMainWindow

YAML = os.path.join(os.path.dirname(__file__), "../yaml/chaos.yaml")

class MainWindow(QMainWindow):
    def __init__(self):
        self.number = 0
        super().__init__()

        # geometry setting ---
        self.setWindowTitle("Simple GUI")
        self.setGeometry(0, 0, 800, 720)

        # Template ==========================================
        self.widgets, self.stylesheet = self.create_all_widgets(YAML)
        for key in self.widgets.keys():
            self.widgets[key].setStyleSheet(self.stylesheet[key])
        # ==============================================

        # --- Your code ----
        # -*-*-*-*-*-*-*-*-*
        # -----------------

        self.show()

    # Template ==========================================
    def create_all_widgets(self, yaml_path: str) -> dict:
        import yaml
        widgets, stylesheet_str = dict(), dict()
        with open(yaml_path, 'r') as f:
            self.yaml_data = yaml.load(f, Loader=yaml.FullLoader)

            for key in self.yaml_data:
                data = create_widgets.create(self, yaml_path, key, os.path.abspath(os.path.dirname(__file__)) + "/../")
                widgets[key], stylesheet_str[key] = data[0], data[1]

        return widgets, stylesheet_str
    # ==============================================

if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = MainWindow()
    # sys.exit(app.exec_())
    sys.exit(app.exec())

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

slider2: # keyname
  type: qslider # QWidgets
  x_center: 500 # x center point
  y_center: 550 # y center point
  rect:
    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

PyQt5 Mode

If you want to use PyQt5, you have to change the qt6_switch.py file.

• Open the file and change the qt6_mode variable to False.
• pip3 install PyQt5
• pip3 install .
