For example, the following changes the Item's state property when the Enter key is pressed: \qml Item { focus: true Keys.onPressed: { if (event.key == Qt.Key_Enter) state = 'ShowDetails'; } } \endqml */ /*! \internal \class QDeclarativeKeyEvent */ /*! \qmlproperty int KeyEvent::key This property holds the code of the key that was pressed or released. See \l {Qt::Key}{Qt.Key} for the list of keyboard codes. These codes are independent of the underlying window system. Note that this function does not distinguish between capital and non-capital letters, use the text() function (returning the Unicode text the key generated) for this purpose. A value of either 0 or \l {Qt::Key_unknown}{Qt.Key_Unknown} means that the event is not the result of a known key; for example, it may be the result of a compose sequence, a keyboard macro, or due to key event compression. */ /*! \qmlproperty string KeyEvent::text This property holds the Unicode text that the key generated. The text returned can be an empty string in cases where modifier keys, such as Shift, Control, Alt, and Meta, are being pressed or released. In such cases \c key will contain a valid value */ /*! \qmlproperty bool KeyEvent::isAutoRepeat This property holds whether this event comes from an auto-repeating key. */ /*! \qmlproperty int KeyEvent::count This property holds the number of keys involved in this event. If \l KeyEvent::text is not empty, this is simply the length of the string. */ /*! \qmlproperty bool KeyEvent::accepted Setting \a accepted to true prevents the key event from being propagated to the item's parent. Generally, if the item acts on the key event then it should be accepted so that ancestor items do not also respond to the same event. */ /*! \qmlclass MouseEvent QDeclarativeMouseEvent \since 4.7 \brief The MouseEvent object provides information about a mouse event. The position of the mouse can be found via the x and y properties. The button that caused the event is available via the button property. */ /*! \internal \class QDeclarativeMouseEvent */ /*! \qmlproperty int MouseEvent::x \qmlproperty int MouseEvent::y These properties hold the position of the mouse event. */ /*! \qmlproperty enum MouseEvent::button This property holds the button that caused the event. It can be one of: \list \o Qt.LeftButton \o Qt.RightButton \o Qt.MidButton \endlist */ /*! \qmlproperty bool MouseEvent::wasHeld This property is true if the mouse button has been held pressed longer the threshold (800ms). */ /*! \qmlproperty int MouseEvent::buttons This property holds the mouse buttons pressed when the event was generated. For mouse move events, this is all buttons that are pressed down. For mouse press and double click events this includes the button that caused the event. For mouse release events this excludes the button that caused the event. It contains a bitwise combination of: \list \o Qt.LeftButton \o Qt.RightButton \o Qt.MidButton \endlist */ /*! \qmlproperty int MouseEvent::modifiers This property holds the keyboard modifier flags that existed immediately before the event occurred. It contains a bitwise combination of: \list \o Qt.NoModifier - No modifier key is pressed. \o Qt.ShiftModifier - A Shift key on the keyboard is pressed. \o Qt.ControlModifier - A Ctrl key on the keyboard is pressed. \o Qt.AltModifier - An Alt key on the keyboard is pressed. \o Qt.MetaModifier - A Meta key on the keyboard is pressed. \o Qt.KeypadModifier - A keypad button is pressed. \endlist For example, to react to a Shift key + Left mouse button click: \qml MouseArea { onClicked: { if (mouse.button == Qt.LeftButton && mouse.modifiers & Qt.ShiftModifier) doSomething(); } } \endqml */ QT_END_NAMESPACE
