Hi! I'm trying to make my first plasmoid in QML and I have some questions (my googling hasn't brought any clear results):
1) What have I to import to be able to use ComboBox and ToolTip plasma elements? PlasmaCore, PlasmaComponents and PlasmaExtras are already imported but seem not to contain them.
2) Is there any way to make standard plasma Button autosizable according to it's content width?
Thank you in advance.

Take a look at the docs at techbase, for example
http://techbase.kde.org/Development/Tut ... ingStarted
http://techbase.kde.org/Development/Tut ... ma/QML/API

Thank you for reply, sredna. I've already looked through that pages and found there many useful information, but not answers for the questions above.

I would suggest asking this question on the Plasma Development mailing list (plasma-devel@kde.org). The people on that list should have the knowledge to answer your questions.

Please make sure to state the version of KDE you are using.
