qtextoption.h Expected unqualified-id before '\x9'

Hi everyone,

So I am getting this strange error:

qtextoption.h:140: error: expected unqualified-id before '\x9'
qtextoption.h:153: error: lvalue required as left operand of assignment

But this is only is I have

Code:

---

#include "PPincludes.h"

---

in my code below for cgui.h:

Code:

---

#ifndef CGUI_H
#define CGUI_H
 
#include <QMainWindow>
#include "PPincludes.h"
 
 
namespace Ui {
    class CGUI;
}
 
//!  The main application class
/*!
  The CGUI class contains declarations of all variables and functions used
  by the application. It is divided into Pre-processing, Run and Post-processing
  groups.
*/
 
class CGUI : public QMainWindow {
    Q_OBJECT
public:
    CGUI(QWidget *parent = 0);
    ~CGUI();
 
protected:
    void changeEvent(QEvent *e);
 
private:
    Ui::CGUI *ui;
 
};
 
#endif // CGUI_H

---

PPincludes.h is blank.

Then, cgui.cpp:

Code:

---

#include "cgui.h"
#include "ui_cgui.h"
 
CGUI::CGUI(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::CGUI)
{
    ui->setupUi(this);
}
 
CGUI::~CGUI()
{
    delete ui;
 
}
 
void CGUI::changeEvent(QEvent *e)
{
    QMainWindow::changeEvent(e);
    switch (e->type()) {
    case QEvent::LanguageChange:
        ui->retranslateUi(this);
        break;
    default:
        break;
    }
}

---

Please help. I am not sure why it is giving me such a strange error.
The error dissappears if I remove #include "PPinclude.h"

Thank you in advance,

Ok I figured it out,
Solution:

in the cgui.cpp file of the form class,

Code:

---

//***Must include QtGui in the beginning of the file***
#include <QtGui>
//***
 
#include <cgui.h>
#include <ui_cgui.h>
 
//etc

Hi ncrusader,
Do you know the reason why
#include<QtGui>

solves the problem?
