Detailed Description

The QKeySequence class encapsulates a key sequence as used by shortcuts.

\inmodule QtGui

In its most common form, a key sequence describes a combination of keys that must be used together to perform some action. Key sequences are used with QAction objects to specify which keyboard shortcuts can be used to trigger actions.

Key sequences can be constructed for use as keyboard shortcuts in three different ways:

\list

For standard shortcuts, a \l{QKeySequence::StandardKey}{standard key} can be used to request the platform-specific key sequence associated with each shortcut.
For custom shortcuts, human-readable strings such as "Ctrl+X" can be used, and these can be translated into the appropriate shortcuts for users of different languages. Translations are made in the "QShortcut" context.
For hard-coded shortcuts, integer key codes can be specified with a combination of values defined by the Qt::Key and Qt::KeyboardModifier enum values. Each key code consists of a single Qt::Key value and zero or more modifiers, such as Qt::ShiftModifier, Qt::ControlModifier, Qt::AltModifier and Qt::MetaModifier. \endlist

For example, \uicontrol{Ctrl P} might be a sequence used as a shortcut for printing a document, and can be specified in any of the following ways:

QKeySequence(QKeySequence::Print);
QKeySequence(tr("Ctrl+P"));
QKeySequence(tr("Ctrl+p"));
QKeySequence(Qt::CTRL | Qt::Key_P);
QKeySequence(Qt::CTRL + Qt::Key_P); // deprecated

Note that, for letters, the case used in the specification string does not matter. In the above examples, the user does not need to hold down the \uicontrol{Shift} key to activate a shortcut specified with "Ctrl+P". However, for other keys, the use of \uicontrol{Shift} as an unspecified extra modifier key can lead to confusion for users of an application whose keyboards have different layouts to those used by the developers. See the \l{Keyboard Layout Issues} section below for more details.

It is preferable to use standard shortcuts where possible. When creating key sequences for non-standard shortcuts, you should use human-readable strings in preference to hard-coded integer values.

QKeySequence objects can be cast to a QString to obtain a human-readable translated version of the sequence. Similarly, the toString() function produces human-readable strings for use in menus. On Apple platforms, the appropriate symbols are used to describe keyboard shortcuts using special keys on the Macintosh keyboard.

An alternative way to specify hard-coded key codes is to use the Unicode code point of the character; for example, 'A' gives the same key sequence as Qt::Key_A.

Note: On Apple platforms, references to "Ctrl", Qt::CTRL, Qt::Key_Control and Qt::ControlModifier correspond to the \uicontrol Command keys on the Macintosh keyboard, and references to "Meta", Qt::META, Qt::Key_Meta and Qt::MetaModifier correspond to the \uicontrol Control keys. In effect, developers can use the same shortcut descriptions across all platforms, and their applications will automatically work as expected on Apple platforms.

This means that it will be shown translated and on Apple platforms it will resemble a key sequence from the menu bar. This enum is best used when you want to display the string to the user.

\value PortableText The key sequence is given in a "portable" format, suitable for reading and writing to a file. In many cases, it will look similar to the native text on Windows and X11.

◆ QKeySequence() [2/6]

QKeySequence::QKeySequence	(	const QString &	key,
		QKeySequence::SequenceFormat	format = NativeText )

Creates a key sequence from the key string, based on format.

For example "Ctrl+O" gives CTRL+'O'. The strings "Ctrl", "Shift", "Alt" and "Meta" are recognized, as well as their translated equivalents in the "QShortcut" context (using QObject::tr()).

Up to four key codes may be entered by separating them with commas, e.g. "Alt+X,Ctrl+S,Q".

This constructor is typically used with \l{QObject::tr()}{tr}(), so that shortcut keys can be replaced in translations:

QMenu *file = new QMenu(this);
file->addAction(tr("&Open..."), QKeySequence(tr("Ctrl+O", "File|Open")),
                this, &MainWindow::open);

Note the "File|Open" translator comment. It is by no means necessary, but it provides some context for the human translator.

If the key sequence has no keys, an empty string is returned.

On Apple platforms, the string returned resembles the sequence that is shown in the menu bar if format is QKeySequence::NativeText; otherwise, the string uses the "portable" format, suitable for writing to a file.
