Style Settings in Qt Quick (+ Designer)

alexander.merkel

Hello,
I am planning to write a set of custom components in a way that other people can use the QtCreator Design mode to create a Gui. I intend to create these components in different styles that can be switched from within the Design mode by inserting the name of a Style in some property field.(This is the most usable way I could come up with.)

I cannot find a proper solution for this problem, all my approaches have some sort of flaw.

Putting all the styles in contextProperties:

-prohibits a style change in Design mode since contextProperty values cannot be accessed. All you get in Design mode is #contextPropertyName# if i am not mistaken.

Creating a global javascript File (.pragma) that has all style values in variables and includes a function that takes a Stylename parameter that changes these variables to the correct values:

if a property is assigned a javascript variable a change of this variable will not trigger a "property changed event" as a change of this property from within qml would. Since all components have several style dependent properties. triggering these changes by hand seems excessive work to me.
IS THERE A REPAINT ALL that could do that???
i also had trouble getting the function to change the variable values in Design mode

I have a (kind of) working solution involving QtObjects holding style properties and a loader dynamically changing its source. But that would involve loading the Style Objects into every Component which might be bad for performance.

Thanks
