- \brief The FontLoader element allows fonts to be loaded by name or URL.
-
- The FontLoader element is used to load fonts by name or URL.
-
- The \l status indicates when the font has been loaded, which is useful
- for fonts loaded from remote sources.
-
- For example:
- \qml
- import QtQuick 1.0
-
- Column {
- FontLoader { id: fixedFont; name: "Courier" }
- FontLoader { id: webFont; source: "http://www.mysite.com/myfont.ttf" }
-
- Text { text: "Fixed-size font"; font.family: fixedFont.name }
- Text { text: "Fancy font"; font.family: webFont.name }
