Creating Qgraphics View code

[amagdy.ibrahim]

I need to create gpraphics view with code,I wrote in the header file
QGraphicsView *view;
then in cpp file
I wrote creating the form

view = new QGraphicsView(&(MdiChild::newFile));
 
void MdiChild::newFile()
 {
     static int sequenceNumber = 1;
 
     isUntitled = true;
     curFile = tr("document%1.txt").arg(sequenceNumber++);
     setWindowTitle(curFile + "[*]");
 
    // connect(document(), SIGNAL(contentsChanged()),
      //       this, SLOT(documentWasModified()));
 }

view = new QGraphicsView(&(MdiChild::newFile));

void MdiChild::newFile()
 {
     static int sequenceNumber = 1;

     isUntitled = true;
     curFile = tr("document%1.txt").arg(sequenceNumber++);
     setWindowTitle(curFile + "[*]");

    // connect(document(), SIGNAL(contentsChanged()),
      //       this, SLOT(documentWasModified()));
 }

To copy to clipboard, switch view to plain text mode 

I have an error
would you please help me?

view = new QGraphicsView(&(MdiChild::newFile));

view = new QGraphicsView(&(MdiChild::newFile));

To copy to clipboard, switch view to plain text mode 

This code seems invalid. What is MdiChild::newFile? What is the error you get?

[amagdy.ibrahim]

mainwindow.h:73:error expected ';' before '*'

I need to create qgraphics in mdichild when I press on new button in the mainwindow

void MdiChild::newFile()
 {
     static int sequenceNumber = 1;
 
     isUntitled = true;
     curFile = tr("document%1.txt").arg(sequenceNumber++);
     setWindowTitle(curFile + "[*]");
 
    // connect(document(), SIGNAL(contentsChanged()),
      //       this, SLOT(documentWasModified()));
 }

void MdiChild::newFile()
 {
     static int sequenceNumber = 1;

     isUntitled = true;
     curFile = tr("document%1.txt").arg(sequenceNumber++);
     setWindowTitle(curFile + "[*]");

    // connect(document(), SIGNAL(contentsChanged()),
      //       this, SLOT(documentWasModified()));
 }

To copy to clipboard, switch view to plain text mode 

so I wrote in constructor mdi::newfile
is that right?

Sorry

view = new QGraphicsView(Mdi->scene,MainWindow);

I have an error on this statement

[amagdy.ibrahim]

I tried this piece of code
view = new QGraphicsView(&(MdiChild::scene),MdiChild);

still error existed object missing reference to MdiChild::scence

error:from this location

please help me urgent

Please, take some book on C++ programming and learn at least basics of C++ first before starting with Qt. The code you wrote simply makes no sense from the syntax point of view.

Thank you for your help,I need to view Qgraphics in Mdi child when I press on new dialog.I aleardy did this step which create Mdi widget.I wrote Qgprhics view in mainwindow.cpp when
I write this line: view = new QGraphicsView(&(MainWindow::scene),this);
qgraphics appears in mainwindow
so logicaclly I wrote this line to appear
view = new QGraphicsView(&(Mdi::scene),MainWindow);
