string
type refers to a free form text string in quotes, e.g. "Hello world!".
范例：
Text { text: "Hello world!" }
Strings have a
length
attribute that holds the number of characters in the string.
QML extends the JavaScript String type with a arg() function to support value substitution.
When integrating with C++, note that any
QString
值
passed into QML from C++
is automatically converted into a
string
value, and vice-versa.
此基本类型由 QML 语言提供。
