Using FURY with Qt

This example demonstrates how to use FURY with a Qt application to create a simple GUI. It integrates FURY’s rendering capabilities with Qt’s event handling and widget system.

import numpy as np

from fury.window import ShowManager, Scene
from fury.lib import QtWidgets
from fury.actor import sphere


app = QtWidgets.QApplication.instance() or QtWidgets.QApplication([])


class Main(QtWidgets.QWidget):
    def __init__(self):
        super().__init__(None)
        self.resize(800, 800)

        self._button = QtWidgets.QPushButton("Hide Sphere", self)
        self._button.clicked.connect(self._on_button_click)
        self.scene = Scene(background=(0, 0, 0, 1))
        self.show_manager = ShowManager(
            scene=self.scene,
            window_type="qt",
            title="Integrate Qt Example",
            qt_app=app,
            qt_parent=self,
        )

        self._sphere_actor = sphere(
            np.zeros((1, 3)),
            colors=(1, 0, 1, 1),
            radii=15.0,
            phi=48,
            theta=48,
        )
        self.scene.add(self._sphere_actor)

        layout = QtWidgets.QHBoxLayout()
        self.setLayout(layout)
        layout.addWidget(self._button)
        layout.addWidget(self.show_manager.window)

    def _on_button_click(self):
        if self._button.text() == "Show Sphere":
            self.scene.add(self._sphere_actor)
            self._button.setText("Hide Sphere")
        else:
            self.scene.remove(self._sphere_actor)
            self._button.setText("Show Sphere")
        self.show_manager.render()


m = Main()
m.setWindowTitle("FURY Qt Example")

m.show_manager.start()
