'fileMenu' was not declared in the scope

[lapdx]

#include "mainwindow.h"
#include "ui_mainwindow.h"

QAction *newAct;


MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

newAct = new QAction(tr("&New"), this);
newAct->setShortcut(tr("Ctrl+N"));
newAct->setStatusTip(tr("Create a new file"));
connect(newAct, SIGNAL(triggered()), this, SLOT(newFile()));


fileMenu = menuBar()->addMenu(tr("&File"));
fileMenu->addAction(newAct);
}

MainWindow::~MainWindow()
{
delete ui;
}

Give me a error: 'fileMenu' was not declared in the scope. What is type of "filemenu"?

[wysota]

Yeah... and? Where did you declare fileMenu?

[lapdx]

QAction *newAct;

QAction *newAct;
QMenu *fileMenu;;

Then please show the complete header code. Do not re-write it yourself - copy and paste (read my sig).

you declare QAction *newAct; in mainwindow.cpp - in global scope!

#include "mainwindow.h"
 #include "ui_mainwindow.h"
 
QAction *newAct; // What is this for???  you say fileMenu is declared after this...

#include "mainwindow.h"
 #include "ui_mainwindow.h"
 
QAction *newAct; // What is this for???  you say fileMenu is declared after this...

To copy to clipboard, switch view to plain text mode 

please use CODE tags for code, not quotes!!

Atleast declare it now. or just include the header file here.

QMenu *fileMenu;;

QMenu *fileMenu;;

To copy to clipboard, switch view to plain text mode 

What is this then? Why are you using two semi colons here?

fileMenu and newAct should be member variables of the MainWindow class or local variables in the constructor depending on the desired scope. They should not be declared as global variables as they are now.
