Hi All-
I'm trying to make Q_INVOKABLE methods on my custom Qt class that allow
get/set of random custom properties by name (stored in the class as a
QMap<QString, QVariant>). However, when I try and call the getter from a QML
context, the QVariant default value arg always comes up as "invalid" (from a
QtCreator debugger viewpoint) - I would have thought that automatic conversion
*to* a QVariant in a QML->CPP transition would be available - am I just doing
it wrong?
Here's some (condensed) sample code:
MyObj::getCustomProp(const QString &propName, const QVariant &defaultValue =
QVariant())
{
if (!mCustomProps.contains(propName))
setCustomProp(propName, defaultValue);
return mCustomProps.value(propName);
}
and the QML that invokes it:
myObj.getCustomProp("MyPropName", true);
This also doesn't work with any well-known type - ie I can't pass a number, a
string, anything, and have it show up as a valid QVariant in getCustomProp.
Any thoughts?
Thanks!
-James
