-Quick start
-===========
-
-New to Qt? Check also the :ref:`faq-section` section at the end of this page.
-In case you own a Qt License, please refer to :ref:`commercial-page`.
-
-.. note:: Having Qt installed in your system will not interfere with your
- PySide6 installation if you do it via ``pip install``, because the Python
- packages (wheels) include already Qt binaries. Most notably, style plugins
- from the system won't have any effect on PySide applications.
-
-Requirements
-------------
-
-Before you can install |project|, first you must install the following software:
-
-* Python 3.7+,
-* We **highly** recommend using a virtual environment, such as
- `venv <https://docs.python.org/3/library/venv.html>`_ or
- `virtualenv <https://virtualenv.pypa.io/en/latest>`_
- and avoid installing PySide6 via ``pip`` in your system.
-
-.. note:: For Windows users, please use the interpreter from https://python.org/download
- rather than the one installed from the Microsoft Store.
-
-Installation
-------------
-
-.. note:: For a commercial installation, refer to :ref:`commercial-page`.
-
-* **Creating and activating an environment**
- You can do this by running the following on a terminal:
-
- * Create environment (Your Python executable might be called ``python3``)::
-
- python -m venv env
-
- * Activate the environment (Linux and macOS)::
-
- source env/bin/activate
-
- * Activate the environment (Windows)::
-
- env\Scripts\activate.bat
-
- Check this animation on how to do it:
-
- .. image:: https://qt-wiki-uploads.s3.amazonaws.com/images/8/8a/Pyside6_install.gif
- :alt: Installation GIF
-
-* **Installing PySide6**
-
- Now you are ready to install the |project| packages using ``pip``.
- From the terminal, run the following command:
-
- * For the latest version::
-
- pip install pyside6
-
- * For a specific version, like 6.4.1::
-
- pip install pyside6==6.4.1
-
- * It is also possible to install a specific snapshot from our servers.
- To do so, you can use the following command::
-
- pip install --index-url=https://download.qt.io/snapshots/ci/pyside/6.4/latest pyside6 --trusted-host download.qt.io
-
- .. note:: Starting with 6.4.3, PySide6 can be used from inside a
- `conda <https://conda.io>`_ environment, but any manual changes you make to
- the ``qt.conf`` file will be ignored. If you want to set custom values to
- the Qt configuration, set them in a ``qt6.conf`` file instead.
- Read more about `qt.conf`_.
-
-.. _`qt.conf`: https://doc.qt.io/qt-6/qt-conf.html
-
-* **Test your installation**
-
- Now that you have |project| installed, test your setup by running the following Python
- constructs to print version information::
-
- import PySide6.QtCore
-
- # Prints PySide6 version
- print(PySide6.__version__)
-
- # Prints the Qt version used to compile PySide6
- print(PySide6.QtCore.__version__)
-
-.. note:: For more information about what's included in the ``pyside6``
- package, check :ref:`package_details`.
-
-Create a Simple Qt Widgets Application
---------------------------------------
-
-Your |project| setup is ready. You can explore it further by developing a simple application
-that prints "Hello World" in several languages. The following instructions will
-guide you through the development process:
-
-* **Imports**
-
- Create a new file named :code:`hello_world.py`, and add the following imports to it.::
-
- import sys
- import random
- from PySide6 import QtCore, QtWidgets, QtGui
-
- The |pymodname| Python module provides access to the Qt APIs as its submodule.
- In this case, you are importing the :ref:`QtCore`, :ref:`QtWidgets`, and :ref:`QtGui` submodules.
-
-* **Main Class**
-
- Define a class named :code:`MyWidget`, which extends :ref:`QWidget` and
- includes a :ref:`QPushButton` and :ref:`QLabel`.::
-
- class MyWidget(QtWidgets.QWidget):
- def __init__(self):
- super().__init__()
-
- self.hello = ["Hallo Welt", "Hei maailma", "Hola Mundo", "Привет мир"]
-
- self.button = QtWidgets.QPushButton("Click me!")
- self.text = QtWidgets.QLabel("Hello World",
- alignment=QtCore.Qt.AlignCenter)
-
- self.layout = QtWidgets.QVBoxLayout(self)
- self.layout.addWidget(self.text)
- self.layout.addWidget(self.button)
-
- self.button.clicked.connect(self.magic)
-
- @QtCore.Slot()
- def magic(self):
- self.text.setText(random.choice(self.hello))
-
- The ``MyWidget`` class has the :code:`magic` member function that randomly
- chooses an item from the :code:`hello` list. When you click the button, the
- :code:`magic` function is called.
-
-* **Application execution**
-
- Now, add a main function where you instantiate :code:`MyWidget` and :code:`show` it.::
-
- if __name__ == "__main__":
- app = QtWidgets.QApplication([])
-
- widget = MyWidget()
- widget.resize(800, 600)
- widget.show()
-
- sys.exit(app.exec())
-
- Run your example by writing the following command: :command:`python hello_world.py`.
-
- Try clicking the button at the bottom to see which greeting you get.
-
- .. image:: images/screenshot_hello.png
- :alt: Hello World application
-
-Create a Simple Quick Application
----------------------------------
-
-To do the same using Qt Quick:
-
-* **Imports**
-
- Create a new file named :code:`hello_world_quick.py`, and add the following imports to it.::
-
- import sys
- from PySide6.QtGui import QGuiApplication
- from PySide6.QtQml import QQmlApplicationEngine
-
-* **Declarative UI**
-
- The UI can be described in the QML language:
-
- .. code-block:: javascript
-
- import QtQuick
- import QtQuick.Controls
- import QtQuick.Layouts
-
- Window {
- width: 300
- height: 200
- visible: true
- title: "Hello World"
-
- readonly property list<string> texts: ["Hallo Welt", "Hei maailma",
- "Hola Mundo", "Привет мир"]
-
- function setText() {
- var i = Math.round(Math.random() * 3)
- text.text = texts[i]
- }
-
- ColumnLayout {
- anchors.fill: parent
-
- Text {
- id: text
- text: "Hello World"
- Layout.alignment: Qt.AlignHCenter
- }
- Button {
- text: "Click me"
- Layout.alignment: Qt.AlignHCenter
- onClicked: setText()
- }
- }
- }
-
- Put the this into a file named :code:`Main.qml` into a directory named
- :code:`Main` along with a file named :code:`qmldir` to describe a basic
- QML module:
-
- .. code-block:: text
-
- module Main
- Main 254.0 Main.qml
-
-* **Application execution**
-
- Now, add a main function where you instantiate a :ref:`QQmlApplicationEngine` and
- load the QML::
-
- import sys
- from PySide6.QtGui import QGuiApplication
- from PySide6.QtQml import QQmlApplicationEngine
-
- if __name__ == "__main__":
- app = QGuiApplication(sys.argv)
- engine = QQmlApplicationEngine()
- engine.addImportPath(sys.path[0])
- engine.loadFromModule("Main", "Main")
- if not engine.rootObjects():
- sys.exit(-1)
- exit_code = app.exec()
- del engine
- sys.exit(exit_code)
