This document describes a set of Python bindings for the Qt widget set. Contact the author at phil@riverbankcomputing.co.uk.

## Introduction

PyQt is a set of Python bindings for the Qt toolkit and available for all platforms supported by Qt, including Windows, Linux, UNIX, MacOS/X and embedded systems such as the Sharp Zaurus and the Compaq iPAQ. They have been tested against Qt versions 1.43 to 3.3.4, Qt Non-commercial, Qtopia 1.5.0, and Python versions 1.5 to 2.4. Qt/Embedded v3 is not supported.

PyQt is available under the GPL license for use with the GPL version of Qt, a a commercial license for use with the commercial version of Qt, a non-commercial license for use with the non-commercial version of Qt v2, and an educational license for use with the educational version of Qt.

There is also an evaluation version of PyQt for Windows. This must be used with the corresponding evaluation version of Qt.

PyQt is built using SIP (a tool for generating Python extension modules for C++ class libraries). SIP v4.2 or later must be installed in order to build and run this version of PyQt.

PyQt for MacOS/X requires Qt v3.1.0 or later and Python v2.3 or later.

The bindings are implemented as a number of Python modules

- `qt` is the main module and contains the core classes and most user interface widgets.

- `qtaxcontainer` contains a sub-set of the classes implemented in Qt's QAxContainer module, part of Qt's ActiveQt framework. (Note that SIP v4.2 or later is required.)

- `qtcanvas` contains the classes implemented in Qt's Canvas module.

- `qtgl` contains the classes implemented in Qt's OpenGL module.

- `qtnetwork` contains the classes implemented in Qt's Network module.

- `qtpe` contains the classes implemented in Qtopia (originally called the Qt Palmtop Environment). It is only supported with Qt/Embedded.

- `qtsql` contains the classes implemented in Qt's SQL module.

- `qttable` contains the classes implemented in Qt's Table module.

- `qtui` contains the classes implemented in Qt's qui library. These allow GUIs to be created directly from Qt Designer's `.ui` files.

- `qtxml` contains the classes implemented in Qt's XML module.

- `qtext` contains useful third-party classes that are not part of Qt. At the moment it contains bindings for QScintilla, the port to Qt of the Scintilla programmer's editor class.

PyQt also includes the `pyuic` and `pylupdate` utilities which correspond to the Qt `uic` and `lupdate` utilities. `pyuic` converts the GUI designs created with Qt Designer to executable Python code. `pylupdate` scans Python code, extracts all strings that are candidates for internationalisation, and creates an XML file for use by Qt Linguist.

### Changes

The changes visible to the Python programmer in this release are as follows.

- Added the `qInstallMsgHandler()` function.

- Added support for QScintilla v1.5 including the `QextScintillaLexerLua` and `QextScintillaLexerRuby` classes.

## Other PyQt Goodies

### Using Qt Designer

Qt Designer is a GPL'ed GUI design editor provided by Trolltech as part of Qt. It generates an XML description of a GUI design. Qt includes `uic` which generates C++ code from that XML.

PyQt includes `pyuic` which generates Python code from the same XML. The Python code is self contained and can be executed immediately.

It is sometimes useful to be able to include some specific Python code in the output generated by `pyuic`. For example, if you are using custom widgets, `pyuic` has no way of knowing the name of the Python module containing the widget and so cannot generate the required `import` statement. To help get around this, `pyuic` will extract any lines entered in the `Comment` field of Qt Designer's `Form Settings` dialog that begin with `Python:` and copies them to the generated output.

Here's a simple example showing the contents of the `Comment` field.

    This comment will be ignored by pyuic.
    Python:
    Python:# Import our custom widget.
    Python:from foo import bar

Here's the corresponding output from `pyuic`.

    from qt import *

    # Import our custom widget.
    from foo import bar

Thanks to Christian Bird, `pyuic` will extract Python code entered using Qt Designer to implement slots. In Qt Designer, when you need to edit a slot and the source editor appears, enter Python code between the curly braces. Don't worry about the correct starting indent level, each line is prepended with a correct indentation.

Make sure that the `ui.h` file is in the same directory as the `.ui` file when using `pyuic`. The `.ui` file implies the name of the `.ui.h` file so there is no need to specify it on the command line.

Here's an example of a simple slot.

    void DebMainWindowFrm::browsePushButtonClicked()
    {
    if self.debugging:
        QMessageBox.critical(self, "Event", "browse pushbutton was clicked!")
    }

Here is the resulting code when `pyuic` is run.

    class DebMainWindowFrm(QMainWindow):
        ...stuff...
        def browsePushButtonClicked(self):
            if self.debugging:
                QMessageBox.critical(self, "Event", "browse pushbutton was clicked!")

Note that indenting is as normal and that `self` and all other parameters passed to the slot are available.

If you use this, you will need to turn off all of the fancy options for the C++ editor in Designer as it tries to force C++ syntax and that's naturally annoying when trying to code in Python.

### Using Qt Linguist

Qt includes the `lupdate` program which parses C++ source files converting calls to the `QT_TR_NOOP()` and `QT_TRANSLATE_NOOP()` macros to `.ts` language source files. The `lrelease` program is then used to generate `.qm` binary language files that are distributed with your application.

Thanks to Detlev Offenbach, PyQt includes the `pylupdate` program. This generates the same `.ts` language source files from your PyQt source files.

## Deploying Commercial PyQt Applications

When deploying commercial PyQt applications it is necessary to discourage users from accessing the underlying PyQt modules for themselves. A user that used the modules shipped with your application to develop new applications would themselves be considered a developer and would need their own commercial Qt and PyQt licenses.

One solution to this problem is the VendorID package. This allows you to build Python extension modules that can only be imported by a digitally signed custom interpreter. The package enables you to create such an interpreter with your application embedded within it. The result is an interpreter that can only run your application, and PyQt modules that can only be imported by that interpreter. You can use the package to similarly restrict access to any extension module.

In order to build PyQt with support for the VendorID package, pass the `-i` command line flag to `configure.py`.

## `pyqtconfig` and Build System Support

The SIP build system (ie. the `sipconfig` module) is described in the SIP documentation. PyQt includes the `pyqtconfig` module that can be used by configuration scripts of other bindings that are built on top of PyQt.

The `pyqtconfig` module contains the following classes:

`Configuration(sipconfig.Configuration)`

  This class encapsulates additional configuration values, specific to PyQt, that can be accessed as instance variables.

  The following configuration values are provided (in addition to those provided by the `sipconfig.Configuration` class):

## Things to be Aware Of

### Python Strings, Qt Strings and Unicode

Unicode support was added to Qt in v2.0 and to Python in v1.6. In Qt, Unicode support is implemented using the `QString` class. It is important to understand that `QString`s, Python string objects and Python Unicode objects are all different but conversions between them are automatic in many cases and easy to achieve manually when needed.

Whenever PyQt expects a `QString` as a function argument, a Python string object or a Python Unicode object can be provided instead, and PyQt will do the necessary conversion automatically.

You may also manually convert Python string and Unicode objects to `QString`s by using the `QString` constructor as demonstrated in the following code fragment.

    qs1 = QString('Converted Python string object')
    qs2 = QString(u'Converted Python Unicode object')

In order to convert a `QString` to a Python string object use the Python `str()` function. Applying `str()` to a null `QString` and an empty `QString` both result in an empty Python string object.

In order to convert a `QString` to a Python Unicode object use the Python `unicode()` function. Applying `unicode()` to a null `QString` and an empty `QString` both result in an empty Python Unicode object.

### Access to Protected Member Functions

When an instance of a C++ class is not created from Python it is not possible to access the protected member functions, or emit the signals, of that instance. Attempts to do so will raise a Python exception. Also, any Python methods corresponding to the instance's virtual member functions will never be called.

### `None` and `NULL`

Throughout the bindings, the `None` value can be specified wherever `NULL` is acceptable to the underlying C++ code.

Equally, `NULL` is converted to `None` whenever it is returned by the underlying C++ code.

### Support for C++ `void *` Data Types

PyQt represents `void *` values as objects of type `sip.voidptr`. Such values are often used to pass the addresses of external objects between different Python modules. To make this easier, a Python integer (or anything that Python can convert to an integer) can be used whenever a `sip.voidptr` is expected.

A `sip.voidptr` may be converted to a Python integer by using the `int()` builtin function.

A `sip.voidptr` may be converted to a Python string by using its `asstring()` method. The `asstring()` method takes an integer argument which is the length of the data in bytes.

### Support for Threads

PyQt implements the full set of Qt's thread classes. Python, of course, also has its own thread extension modules. If you are using SIP v4 (or later) and Python v2.3.5 (or later) then PyQt does not impose any additional restrictions. (Read the relevant part of the Qt documentation to understand the restrictions imposed by the Qt API.)

If you are using earlier versions of either SIP or Python then it is possible to use either of the APIs so long as you follow some simple rules.

- If you use the Qt API then the very first `import` of one of the PyQt modules must be done from the main thread.

- If you use the Python API then all calls to PyQt (including any `import`s) must be done from one thread only. Therefore, if you want to make calls to PyQt from several threads then you must use the Qt API.

- If you want to use both APIs in the same application then all calls to PyQt must be done from threads created using the Qt API.

The above comments actually apply to any SIP generated module, not just PyQt.

### Garbage Collection

C++ does not garbage collect unreferenced class instances, whereas Python does. In the following C++ fragment both colours exist even though the first can no longer be referenced from within the program:

    c = new QColor();
    c = new QColor();

In the corresponding Python fragment, the first colour is destroyed when the second is assigned to `c`:

    c = QColor()
    c = QColor()

In Python, each colour must be assigned to different names. Typically this is done within class definitions, so the code fragment would be something like:

    self.c1 = QColor()
    self.c2 = QColor()

Sometimes a Qt class instance will maintain a pointer to another instance and will eventually call the destructor of that second instance. The most common example is that a `QObject` (and any of its sub-classes) keeps pointers to its children and will automatically call their destructors. In these cases, the corresponding Python object will also keep a reference to the corresponding child objects.

So, in the following Python fragment, the first `QLabel` is not destroyed when the second is assigned to `l` because the parent `QWidget` still has a reference to it.

    p = QWidget()
    l = QLabel('First label',p)
    l = QLabel('Second label',p)

### C++ Variables

Access to C++ variables is supported. They are accessed as Python instance variables. For example:

    tab = QTab()
    tab.label = "First Tab"
    tab.r = QRect(10,10,75,30)

Global variables and static class variables are effectively read-only. They can be assigned to, but the underlying C++ variable will not be changed. This may change in the future.

Access to protected C++ class variables is not supported. This may change in the future.

### Multiple Inheritance

It is not possible to define a new Python class that sub-classes from more than one Qt class.

### i18n Support

Qt implements i18n support through the Qt Linguist application, the `QTranslator` class, and the `QApplication::translate()`, `QObject::tr()` and `QObject::trUtf8()` methods. Usually the `tr()` method is used to obtain the correct translation of a message. The translation process uses a message context to allow the same message to be translated differently. `tr()` is actually generated by `moc` and uses the hardcoded class name as the context. On the other hand, `QApplication::translate()` allows to context to be explicitly stated.

Unfortunately, because of the way Qt implents `tr()` (and `trUtf8()`) it is not possible for PyQt to exactly reproduce its behavour. The PyQt implementation of `tr()` (and `trUtf8()`) uses the class name of the instance as the context. The key difference, and the source of potential problems, is that the context is determined dynamically in PyQt, but is hardcoded in Qt. In other words, the context of a translation may change depending on an instance's class hierarchy.

    class A(QObject):
        def __init__(self):
            QObject.__init__(self)

        def hello(self):
            return self.tr("Hello")

    class B(A):
        def __init__(self):
            A.__init__(self)

    a = A()
    a.hello()

    b = B()
    b.hello()

In the above the message is translated by `a.hello()` using a context of `A`, and by `b.hello()` using a context of `B`. In the equivalent C++ version the context would be `A` in both cases.

The PyQt behaviour is unsatisfactory and may be changed in the future. It is recommended that `QApplication.translate()` be used in preference to `tr()` (and `trUtf8()`). This is guaranteed to work with current and future versions of PyQt and makes it much easier to share message files between Python and C++ code. Below is the alternative implementation of `A` that uses `QApplication.translate()`.

    class A(QObject):
        def __init__(self):
            QObject.__init__(self)

        def hello(self):
            return qApp.translate("A","Hello")

Note that the code generated by `pyuic` uses `QApplication.translate()`.

## Signal and Slot Support

A signal may be either a Qt signal (specified using `SIGNAL()`) or a Python signal (specified using `PYSIGNAL()`).

A slot can be either a Python callable object, a Qt signal (specified using `SIGNAL()`), a Python signal (specified using `PYSIGNAL()`), or a Qt slot (specified using `SLOT()`).

You connect signals to slots (and other signals) as you would from C++. For example:

    QObject.connect(a,SIGNAL("QtSig()"),pyFunction)
    QObject.connect(a,SIGNAL("QtSig()"),pyClass.pyMethod)
    QObject.connect(a,SIGNAL("QtSig()"),PYSIGNAL("PySig"))
    QObject.connect(a,SIGNAL("QtSig()"),SLOT("QtSlot()"))
    QObject.connect(a,PYSIGNAL("PySig"),pyFunction)
    QObject.connect(a,PYSIGNAL("PySig"),pyClass.pyMethod)
    QObject.connect(a,PYSIGNAL("PySig"),SIGNAL("QtSig()"))
    QObject.connect(a,PYSIGNAL("PySig"),SLOT("QtSlot()"))

When a slot is a Python method that corresponds to a Qt slot then a signal can be connected to either the Python method or the Qt slot. The following connections achieve the same effect.

    sbar = QScrollBar()
    lcd = QLCDNumber()

    QObject.connect(sbar,SIGNAL("valueChanged(int)"),lcd.display)
    QObject.connect(sbar,SIGNAL("valueChanged(int)"),lcd,SLOT("display(int)"))

The difference is that the second connection is made at the C++ level and is more efficient.

Disconnecting signals works in exactly the same way.

Any instance of a class that is derived from the `QObject` class can emit a signal using the `emit` method. This takes two arguments. The first is the Python or Qt signal, the second is a Python tuple which are the arguments to the signal. For example:

    a.emit(SIGNAL("clicked()"),())
    a.emit(PYSIGNAL("pySig"),("Hello","World"))

Note that when a slot is a Python callable object it's reference count is not increased. This means that a class instance can be deleted without having to explicitly disconnect any signals connected to its methods. However, it also means that using lambda expressions as slots will not work unless you keep a separate reference to the expression to prevent it from being immediately garbage collected.

Qt allows a signal to be connected to a slot that requires fewer arguments than the signal passes. The extra arguments are quietly discarded. Python slots can be used in the same way.

## Static Member Functions

Static member functions are implemented as Python class functions. For example the C++ static member function `QObject::connect()` is called from Python as `QObject.connect()` or `self.connect()` if called from a sub-class of `QObject`.

## Enumerated Types

Enumerated types are implemented as a set of simple variables corresponding to the separate enumerated values.

When using an enumerated value the name of the class (or a sub-class) in which the enumerated type was defined in must be included. For example:

    Qt.SolidPattern
    QWidget.TabFocus
    QFrame.TabFocus

## Module Reference Documentation

The following sections should be used in conjunction with the normal class documentation - only the differences specific to the Python bindings are documented here.

In these sections, Not yet implemented implies that the feature can be easily implemented if needed. Not implemented implies that the feature will not be implemented, either because it cannot be or because it is not appropriate.

If a class is described as being fully implemented then all non-private member functions and all public class variables have been implemented.

If an operator has been implemented then it is stated explicitly.

Classes that are not mentioned have not yet been implemented.
