QWebView within QTabWidget: Calling a URL crash the whole Program

MeerMusik

Hello.

I have created a new QTabWidget and added a TextEditor and a QWebView.

The Problem is, when i try to open a URL, the complete Program crash. I know i am missing something.

Here is part of the Code from mainwindow.h
@
private:
Ui::MainWindow *ui;
QTabWidget *tabWidgetMainWindow;
QWebView *BrowserModule;
QTextEdit *textEditor;
@

Part of mainwindow.cpp:
@
//QTextEdit for use in the tabWidgetMainWindow
QTextEdit *textEditor = new QTextEdit;
//The QWebView - But how can i Access+use it within the QTabWidget
QWebView *BrowserModule = new QWebView;

//New QTabWidget in the QMainWindow
QTabWidget *tabWidgetMainWindow = new QTabWidget(this);
tabWidgetMainWindow->setMinimumSize(800,600);
tabWidgetMainWindow->addTab(textEditor, "Editor");
tabWidgetMainWindow->addTab(BrowserModule, "Browser");
tabWidgetMainWindow->setCurrentIndex(1);
tabWidgetMainWindow->show();

//Activate the whole thing in the last step
setCentralWidget(tabWidgetMainWindow);

//Keep this thing off as it kills the QTabWidget...
//ui->setupUi(this);

@

This Action is used to open the URL (its a Menu Point):
@
void MainWindow::ListeAllerAKPads()
{
QString link = "http://wiki.piratenpartei.de";
BrowserModule->setUrl(link);
//ui->webView->setUrl(link);
//DesktopServices::openUrl(QUrl(link));
}
@

Thanks!

Hi,

You are shadowing (i.e. calling a local variable the same name as a member variable) your member variables in your constructor so they are not initialized.

Thanks for the Description whats going on.

But what is the correct or at least working way to Access the QWebView within the QTabWidget?

When i remove / disable
@
QWebView *BrowserModule;
@

from the Header File, i got the Compile Error
"BrowserModule was not declared in this scope"

As silly as it sounds, just don't shadow your member variables. Use them in the constructor

Well i am not sure how to do that but i will look into it. Thanks

replace
@QTextEdit *textEditor = new QTextEdit;@

by

@textEditor = new QTextEdit;@

Thank You!
