Hi,
Thanks for the suggestion. I ended up implementing it like this-
$ cat theme/v2/Theme.qml
pragma Singleton
import QtQuick 2.10
import QtQuick.Window 2.3
Item {
visible: false
GlassColors {
id: glassColors
}
PlatinumColors {
id: platinumColors
}
readonly property var colors: glassColors
readonly property var dialogColors: platinumColors
...
...
}
$ cat theme/v2/ThemeContext.qml
import QtQuick 2.10
Item {
id: root
visible: false
readonly property var _inheritedTheme:
SoStronk.contextPropertyForQmlObject(root.parent, "theme")
readonly property bool _inheritedDialogColors: _inheritedTheme &&
_inheritedTheme.dialogColors ? true : false
property bool dialogColors: false
readonly property var colors: dialogColors ||
_inheritedDialogColors ? Theme.dialogColors : Theme.colors
}
where contextPropertyForQmlObject is a C++ function which returns the
value of a property under the context of the specified object.
Its used like this-
$ cat SoStronkStyle/Button.qml
import QtQuick 2.10
import QtQuick.Templates 2.3 as T
import SoStronk.theme 0.2
T.Button {
id: control
ThemeContext {
id: theme
}
...
// access theme.colors.foregroundColor
And whenever I create a dialog-
ThemeContext {
id: theme
dialogColors: true
}
So then any Button accessing theme.colors will end up referring to
dialogColors :)
