Use a QML Singleton.
Please reference "Approach 2" on this page
-- The ugly QTBUG-34418 comments are mine.
These are the pieces you need:
Style.qml
pragma Singleton
import QtQuick 2.0
QtObject {
property color mainbg: 'red'
}
qmldir
This file must be in the same folder as the singleton .qml file (Style.qml
in our example) or you must give a relative path to it. qmldir
may also need to be included by the .qrc resource file. More information about qmldir files can be found here.
# qmldir
singleton Style Style.qml
How to Reference
import QtQuick 2.0
import "." // this is needed when referencing singleton object from same folder
Rectangle {
color: Style.mainbg // <- there it is!!!
width: 240; height 160
}
This approach is available since Qt5.0. You need a folder import
statement even if referencing the QML singleton in the same folder. If is the same folder, use: import "."
This is the bug that I documented on the qt-project page (see QTBUG-34418, singletons require explicit import to load qmldir file).
