Problem with setCentralWidget

I have in Konstruktor a setCentralWidget defined,

Code:

---

MainWin::MainWin()
{
    plotter = new Plotter; //Plotter is a custom Widget
    textEdit = new QTextEdit;
    setCentralWidget(plotter);
}

---

in function changeToText(), and changeToPlotter(), I want to change the central Widget
so write:

Code:

---

MainWin::changeTotext()
{
    setCentralWidget(textEdit);
}
 
MainWin::changeToPlotter()
{
    setCentralWidget(plotter);
}

---

but at last i can`t change it, what`s wrong?:confused:

thanks for your help!

How are u calling the changeToText and changeToPLotter functions ??

I am not sure if you can set central widget twice.
You may try this - set a QStackedWidget as central widget for the main window, and on the changeToText and changeToPLotter functions, set the text or plotter as the widget :)

I call them like this:

Code:

---

Void MainWin::creatActions()
{
    ...
    connect(newAct, SIGNAL(triggered()), this, SLOT(changeToText()));
    ...
}

---

it`s a litte complex,
now i can see the TextEditor Window, if i call changeToText,
but if i call changeToPlotter further, got a error Message..:confused:

QStackedWidget is a good idea, i will try it .thanks
