How to embed Ogre3d in qt5 as a widget

[timob256]

I started the starter project in qt5.11, but I can't show everything in one window.

this moment i have two windows :(

#ifndef WIDGET_H
#define WIDGET_H

#include <QWidget>
#include <QGridLayout>
#include "QTOgreWindow.h"
#include "SdkQtCameraMan.h"

class Widget : public QWidget
{
    Q_OBJECT

public:
    Widget(QWidget *parent = 0);
    ~Widget();

protected:
    QGridLayout* gl_layaout;
};

#endif // WIDGET_H


#include "widget.h"

Widget::Widget(QWidget *parent)
    : QWidget(parent)
{
    gl_layaout = new QGridLayout(parent);
    QTOgreWindow * ogreWindow = new QTOgreWindow ();
    ogreWindow->show();

    QWidget *container = QWidget::createWindowContainer(ogreWindow);
    gl_layaout->addWidget(container);

    this->setLayout(gl_layaout);

}

Widget::~Widget()
{

}

what am I doing wrong ?? how to put an ogre in a QWidget right ??

I know nothing about this Ogre stuff and its window, nor do you explain for people like me what exactly is wrong in your pic. But why are you using parent here? Shouldn't it be this?

EDIT Oh, later you have this->setLayout(gl_layaout);, so maybe this won't matter after that? I would still change your current, just in case.

Show all of your code for the project. You are probably creating an instance of Widget to be separate window instead of adding it to the layout of your main window.

I don't understand the problem - why do you suddenly use QWidget::createWindowContainer() again when you found a proper solution in your previous thread?

QWindows not unit setLayout ? install in element, not posible.

Don't know what this means.

this->setLayout(gl_layaout[3]); // this not work !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Don't know what this means.

All your widgets are created with parent as their parent, instead of this. Since I wrote earlier

But why are you using parent here? Shouldn't it be this?

do you not think this applies to your case? Why?

You are creating your widgets with a parent of parent of QTOgreWindow, and then this->setLayout(gl_layaout[3]); setting the layout on this. I don't get what you are trying to do or why.

UPDATE
I see you have now taken this question to https://forum.qt.io/topic/132674/how-do-i-put-a-qlayout-in-a-qwindow. It's always helpful to others if you cross-reference posts like this.

I see now that my "But why are you using parent here? Shouldn't it be this?" is not applicable to QWindow. I will post into your other thread.
