Hi everyone,

Recently I've started a porting of my plasmoids and dataengines to the newest Plasma and found some problems with it. I've ported a DataEngine w\o any problem, but I have issues about a Plasmoid. I've read API reference and look at examples from plasma-next and didn't find solutions.

First of all I want say that I don't plan to use QML/JS now and plan to develop of my plasmoids in pure C++. Also I try to avoid using deprecated functions.

• Is there any alternative to

  Code: Select all

  Plasma::PopupApplet

  ? If there is not, is there a plan to implement this?
• Is there a possibility to paint complex UI w\o using QML? For example, I didn't find old

  Code: Select all

  Applet::setLayout()

  and

  Code: Select all

  PopupApplet::setWdiget()

  methods, which can be used for adding pure Qt elements to UI.
• How can I connect DataEngine to my Plasmoid? The old method which I used is

  Code: Select all

  dataEnigne()

  , some new applets use this method too, but it doesn't exist in the newest Plasma headers. Some new widgets such as nm-applet use

  Code: Select all

  Plasma::DataEngineManager::self()->engine()

  construction, but

  Code: Select all

  Plasma::DataEngineManager

  class doesn't exist in the Plasma too.

If you need a reference to my plasmoid, example on which I'm working now may be found here (it is more simple than the second one).

Thank you in advance!

I would suggest asking about this on the plasma-devel@kde.org mailing list. I'm not entirely sure, but I think QML is now the preferred language for implementing Plasma applets.

I have tried to write to the mailing list, but since I don't subscribe to it, it is still waiting moderator approval

I know that qml is preferred, but plasmoid core still is usually written on c++. Also the main part of the project on c++, so I don't want to use additional language if it is not strongly required.

That makes sense. Please note that people may have replied to your mail only on list, so you might want to check the list archives to see if there has been a reply.
