/*!
\qmlclass KeyEvent QFxKeyEvent
\brief The KeyEvent element provides information about a key event.
For example, the following changes the Item's state property when the Enter
key is pressed:
\code
<Item focus="true">
<onKeyPress>if (event.key == Qt.Key_Enter) state = 'ShowDetails';</onKeyPress>
</Item>
\endcode
The \l KeyActions element could also be used to achieve the above with
a clearer syntax.
\sa KeyActions
*/
/*!
\internal
\class QFxKeyEvent
*/
/*!
\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.
*/
/*!
\qmlclass MouseEvent QFxMouseEvent
\brief The MouseEvent element 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 QFxMouseEvent
*/
/*!
\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 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:
\code
<MouseRegion>
<onClick>
<![CDATA[
if (mouse.button == Qt.LeftButton && mouse.modifiers & Qt.ShiftModifier) doSomething();
]]>
</onclick>
</MouseRegion>
\endcode
