\title QML Basic Types
QML uses a set of property types, which are primitive within QML.
These basic types are referenced throughout the documentation of the
QML elements. Almost all of them are exactly what you would expect.
\annotatedlist qmlbasictypes
*/
/*!
\qmlbasictype int
\ingroup qmlbasictypes
\brief An integer is a whole number, e.g. 0, 10, or -20.
An integer is a whole number, e.g. 0, 10, or -20. The possible \c
int values range from around -2000000000 to around 2000000000,
although most elements will only accept a reduced range (which they
mention in their documentation).
Example:
\qml
Item { width: 100; height: 200 }
\endqml
\sa {QML Basic Types}
*/
/*!
\qmlbasictype bool
\ingroup qmlbasictypes
\brief A boolean is a binary true/false value.
A boolean is a binary true/false value.
Example:
\qml
Item { focus: true; clip: false }
\endqml
\sa {QML Basic Types}
*/
/*!
\qmlbasictype real
\ingroup qmlbasictypes
\brief A real number has a decimal point, e.g. 1.2 or -29.8.
A real number has a decimal point, e.g. 1.2 or -29.8.
Example:
\qml
Item { width: 100.45; height: 150.82 }
\endqml
\note In QML all reals are stored in single precision, \l
{http://en.wikipedia.org/wiki/IEEE_754} {IEEE floating point}
format.
\sa {QML Basic Types}

/*!
\qmlbasictype string
\ingroup qmlbasictypes
\brief A string is a free form text in quotes, e.g. "Hello world!".
A string is a free form text in quotes, e.g. "Hello world!".
Example:
\qml
Text { text: "Hello world!" }
\endqml
\sa {QML Basic Types}

/*!
\qmlbasictype url
\ingroup qmlbasictypes
\brief A URL is a resource locator, like a file name.
A URL is a resource locator, like a file name. It can be either
absolute, e.g. "http://qtsoftware.com", or relative, e.g.
"pics/logo.png". A relative URL is resolved relative to the URL of
the component where the URL is converted from a JavaScript string
expression to a url property value.
Example:
\qml
Image { source: "pics/logo.png" }
\endqml
\raw HTML
\endraw
\sa {QML Basic Types}

/*!
\qmlbasictype color
\ingroup qmlbasictypes
\brief A color is a standard color name in quotes.
A color is a standard color name in quotes. It is normally specified
as an \l {http://www.w3.org/TR/SVG/types.html#ColorKeywords} {SVG
color name}. These names include colors like "red", "green" and
"lightsteelblue".
If the color you want isn't part of this list, colors can also be
specified in hexidecimal triplets or quads that take the form \c
"#RRGGBB" and \c "#AARRGGBB" respectively. For example, the color
red corresponds to a triplet of \c "#FF0000" and a slightly
transparent blue to a quad of \c "#800000FF".
Example:
\qml
Rectangle { color: "steelblue" }
Rectangle { color: "#FF0000" }
Rectangle { color: "#800000FF" }
\endqml
\sa {QML Basic Types}
*/
/*!
\qmlbasictype point

\brief A point is specified as "x,y".
A point is specified as "x,y".
Example:
\qml
Widget { pos: "0,20" }
\endqml

\brief A size is specified as "width x height".
A size is specified as "width x height".
Example:
\qml
Widget { size: "150x50" }

/*!
\qmlbasictype rect
\ingroup qmlbasictypes
\brief A rect is specified as "x, y, width x height".
A rect is specified as "x, y, width x height".
Example:
\qml
Widget { geometry: "50,50,100x100" }
\endqml
\sa {QML Basic Types}
*/
/*!
\qmlbasictype date
\ingroup qmlbasictypes
\brief A date is specified as "YYYY-MM-DD".
A date is specified as "YYYY-MM-DD".
Example:
\qml
DatePicker { minDate: "2000-01-01"; maxDate: "2020-12-31" }

Example:
\qml
TimePicker { time: "14:22:15" }

\brief A font type has the properties of a QFont.
A font type has the properties of a QFont. The properties are:
\list
\o \c string font.family
\o \c bool font.bold
\o \c bool font.italic
\o \c bool font.underline
\o \c real font.pointSize
\o \c int font.pixelSize

/*!
\qmlbasictype action
\ingroup qmlbasictypes
\brief The action type has all the properties of QAction.
The action type has all the properties of QAction. The properties
are:
\list
\o \c slot action.trigger - invoke the action
\o \c bool action.enabled - true if the action is enabled
\o \c string action.text - the text associated with the action
\endlist
Actions are used like this:
\qml
MouseArea { onClicked: MyItem.myaction.trigger() }
State { name: "enabled"; when: MyItem.myaction.enabled == true }
Text { text: MyItem.someaction.text }
\endqml
\sa {QML Basic Types}
*/
/*!
\qmlbasictype list
\ingroup qmlbasictypes
\brief A list of objects.
A list of objects. While not technically a basic type, QML also
supports lists of object types. When used from QML, the engine
automatically appends each value to the list.
For example, the \l Item class contains a list property named
children that can be used like this:
\qml
Item {
children: [
Item { id: child1 },
Rectangle { id: child2 },
Text { id: child3 }
]
}
\endqml
\c Child1, \c Child2 and \c Child3 will all be added to the children list
in the order in which they appear.
\sa {QML Basic Types}

/*!
\qmlbasictype vector3d
\ingroup qmlbasictypes
\brief A vector3d is specified as "x,y,z".
A vector3d is specified as "x,y,z".
\qml
Rotation { angle: 60; axis: "0,1,0" }
\endqml
or with the \c{Qt.vector3d()} helper function:
\qml
Rotation { angle: 60; axis: Qt.vector3d(0, 1, 0) }
\endqml
or as separate \c x, \c y, and \c z components:
\qml
Rotation { angle: 60; axis.x: 0; axis.y: 1; axis.z: 0 }
\endqml
\sa {QML Basic Types}
