<![CDATA[QML and Own C++ Object/Plugin]]>Hi;

I wrote my own plugin and object. Problem is, C++ object's parent always null... Why ?

In QML :
...
ChRSM
{
id : chRSM
}
...

In C++ :
CChRSM::CChRSM(QObject* ChParent /= NULL/)
: QObject(
ChParent)
....

Thanks...

Like here i guess
http://doc.qt.io/qt-5/qtqml-tutorials-extending-qml-example.html

Maybe parent is set after CChRSM is constructed.

What is the problem with parent being NULL ?

ApplicationWindow
{
id : window
width : 360
height : 520
visible : true
title : "Quasar"

header: ToolBar
{
	id					: chObject
	Material.foreground	: "white"

	RowLayout
	{
		spacing			: 20
		anchors.fill	: parent

		ChRSM
		{
			id		: chRSM
		}

.
...
....

You mean you made a custom QML component in c++ and when used
in QML, the c++ object created by the engine is
not being given a parent in constructor?

But what is the parent in QML you show ?
