Dear all,
I'm reading the doc in order to implement plugins into my Qt 4.8
application.
The manual says that I need first to define the plugin interface as a pure
virtual class. In the example it does not inherit
Hi Etienne,
The 4.8.5 doco for QObject.qobject_cast links to the Plug Paint example for
use of qobject_cast with interfaces. Mind you, it incorrectly shows the
return type as QWidget. Hopefully that doco has been rewritten in v5!
Hope that helps,

Hi Etienne,
there are two requirements:
1. The interface must be pure virtual (so it cannot derive from QObject)
2. qobject_cast requires a QObject subclass
Hence, your plugin implementation must inherit from both. The
implementation itself can derive from QObject but the interface cannot.
The

But you are able to assign the ID or is it built-in? I don't get the
problem, although I have not used the ComboBox, so
How can I call the function implementation in a base class, if the class
overrides the definition? Here is an example:
Base.qml:
---
import QtQuick 2.2
Item {
function myFunc() {
console.log( Base myFunc called );
}
}
---
Derived.qml:
---
If you use QT_NO_CAST_FROM_ASCII in your project, you will have to surround
your names with QStringLiteral() in calls to QQmlContext::setContextProperty().
Then, however, the QML Editor will not recognize your names and overlay your
code with a warning. How can I get around that?

Thanks for your explanations!
Let's start working on the plugin system...

Alexander, do you have another use case in mind? It might clarify your
requirement. (I haven't played with QML yet but I thought all QObject
info is exposed to javascript and the components anyway - isn't that how
the linkage is achieved?)
The only use-case I have in mind is extending

The first problem is that initially the effect is not shown, then when I click

How can I call the function
I would guess there is something you are doing in the qml file which is a
slow operation.
Can you tell us a bit more about what you are doing and which components
you are using?
One thing which helps is to only load the items initially visible and stick
optional items into Loader elements.

Hello Torgeir,
Do be a bit more specific a ~1sec startup is for anything. Just a
Window { Text{text: Hello world}} will have that kind of startup
time.
I would really need an onCLick show up of the window itself, the
content doesn't need to be instantly there.
I am writing a desktop environment

Profile that. What is the time spent on?

I hope you have set the MouseArea::drag.target correctly? Make sure that
your drag target is either Image or it's parent. Also make sure that your
drag.target does not have anchors set for drag.axis direction, for example
a drag target anchored left and right can not be moved in x direction.
