\brief Converts numbers to strings with the defined precision.
|
||
|
|
|
||
|
|
The StringMapper type maps numbers to strings. The string mapper
|
||
|
|
\l input property is bound to the \c value property of a control that
|
||
|
|
provides the number and the \l text property of the string mapper is
|
||
|
|
mapped to the \c text property of type that displays the string.
|
||
|
|
|
||
|
|
Designers can use the String Mapper type in \QDS instead of writing
|
||
|
|
JavaScript expressions.
|
||
|
|
|
||
|
|
\section1 Example Usage
|
||
|
|
|
||
|
|
In the following example, we use \l Text type to display the numerical
|
||
|
|
value of a \l Slider type as a string:
|
||
|
|
|
||
|
|
\code
|
||
|
|
Rectangle {
|
||
|
|
Slider {
|
||
|
|
id: slider
|
||
|
|
value: 0.5
|
||
|
|
}
|
||
|
|
Text {
|
||
|
|
id: text1
|
||
|
|
text: stringMapper.text
|
||
|
|
}
|
||
|
|
StringMapper {
|
||
|
|
id: stringMapper
|
||
|
|
input: slider.value
|
||
|
|
}
|
||
|
|
}
|
||
|
|
\endcode
|
||
|
|

|
||

|
QtObject {

id: object
|

|
||
|
|
/*!

|

*/
|
||
|

property real input: 0
|
||
|
|
|

|
|
/*!

|

|
||
|
|
|
||
|
|
/*!
|

|

|
