Combine Widgets in a new class

[sedi]

Hi,
I'm trying to build a new class that provides a combination of two QWidgets: one title bar and one collapsible (->hideable) content widget ("panel"). As I will need several very different panel layouts I have an "abstract" (not really virtual) class that is inherited - the heir doesn't change anything as of now, though.

The code compiles, but I don't see the desired appearance - As for now I have put a QPushButton in titleBarWidget and panelWidget, but both seem to be displayed on top of each other.

I am pretty sure it is a very simple beginner's problem. I am very new to C++ and Qt so I might be lacking a very basic concept here. My code:

AbstractCont::AbstractCont(QWidget *parent) :
    QWidget(parent)
{
 
    this->setVisible(true);
    this->resize(400,400);
    this->show();
 
    this->titleBarWidget = new QWidget(this);
    this->titleBarWidget->setVisible(true);
    this->titleBarWidget->resize(100,100);
    this->titleBarWidget->show();
    this->titleBarWidget->setBackgroundRole(QPalette::Window);
 
    QPushButton *pushButt1 = new QPushButton("Title", this->titleBarWidget);
    pushButt1->resize(50,50);
    pushButt1->show();
 
    this->panelWidget=new QWidget(this);
    this->panelWidget->setVisible(true);
    this->panelWidget->resize(100,100);
    this->panelWidget->show();
 
    QPushButton *pushButt2 = new QPushButton("Panel", this->panelWidget);
    pushButt2->resize(50,50);
    pushButt2->show();
}

AbstractCont::AbstractCont(QWidget *parent) :
    QWidget(parent)
{

    this->setVisible(true);
    this->resize(400,400);
    this->show();

    this->titleBarWidget = new QWidget(this);
    this->titleBarWidget->setVisible(true);
    this->titleBarWidget->resize(100,100);
    this->titleBarWidget->show();
    this->titleBarWidget->setBackgroundRole(QPalette::Window);
    
    QPushButton *pushButt1 = new QPushButton("Title", this->titleBarWidget);
    pushButt1->resize(50,50);
    pushButt1->show();

    this->panelWidget=new QWidget(this);
    this->panelWidget->setVisible(true);
    this->panelWidget->resize(100,100);
    this->panelWidget->show();

    QPushButton *pushButt2 = new QPushButton("Panel", this->panelWidget);
    pushButt2->resize(50,50);
    pushButt2->show();
}

To copy to clipboard, switch view to plain text mode 

This is used by:

Cont_Anwesenheit::Cont_Anwesenheit(...):AbstractCont(parent)
{
};

Cont_Anwesenheit::Cont_Anwesenheit(...):AbstractCont(parent)
{
};

To copy to clipboard, switch view to plain text mode 

Which is again called by:

AbstractCont *cont = new Cont_Anwesenheit("Die ID","Kursname", this->model, this->scene, dock);

AbstractCont *cont = new Cont_Anwesenheit("Die ID","Kursname", this->model, this->scene, dock);

To copy to clipboard, switch view to plain text mode 

The variable cont has to be able to hold different heritages of AbstractCont, thus the type.

What I see is attached: just the Button with "Panel". What I like to achieve (just an example, not exactly) is also attached

Any help would be gratefully appreciated!

Best Regards,
Sebastian
