[Solved]Project suddenly doesn't compile

[Gillou_beginqt]

I am working on project right now. For two days I took a break and didn't work on my project. After those two days I compiled my program who was working before and now I got errors from classes I didn't even use. During those two days no changes had been made to the code

Hi,

I'd check that your Qt headers haven't been modified by e.g. a hasty search/replace.

[Gillou_beginqt]

From what I know my Qt Hearders haven't been modified. What is the issue then?

[hskoglund]

Hi if you compile in Release mode do you get the same errors?

[Gillou_beginqt]

Yes exactly the same in release mode

[hskoglund]

Hi, do you have the code for panelstack.h?

[Gillou_beginqt]

Here the code

#ifndef PANELSTACK_H
#define PANELSTACK_H

#include <QWidget>
#include <QLabel>
#include <QStack>
#include <QStackedWidget>
#include "abstractpanel.h"

class PanelStack : public QWidget
{
    Q_OBJECT
public:

     static PanelStack *instance();

     int addPanel( AbstractPanel* );
     void showPanel( int );
     PanelStack();


public slots:
     void home();
     void back();

private:

     static PanelStack *m_instance;

     void showTopPanel();

   //  QLabel *m_titleLabel;

     QStackedWidget *m_panelStack;
     QStack<int> m_history;

};

#endif // PANELSTACK_H


#include "panelstack.h"
#include "abstractpanel.h"
#include <QStackedWidget>
#include <QGridLayout>


PanelStack *PanelStack::m_instance = 0;
PanelStack *PanelStack::instance()
{
    if( !m_instance )
        m_instance = new PanelStack();

    return m_instance;
}

int PanelStack::addPanel( AbstractPanel *panel )
{
    return m_panelStack->addWidget( panel );
}

void PanelStack::showPanel( int index )
{
    m_history.push( index );
    showTopPanel();
}

void PanelStack::showTopPanel()
{
    m_panelStack->setCurrentIndex( m_history.top() );
    AbstractPanel *panel = dynamic_cast<AbstractPanel*>( m_panelStack->widget( m_history.top() ) );

    panel->enterPanel();
   // m_titleLabel->setText( panel->titleText() );
}

PanelStack::PanelStack() : QWidget()
{
    //m_titleLabel = new QLabel();
    //m_titleLabel->setAlignment( Qt::AlignCenter );
    m_panelStack = new QStackedWidget();

    QGridLayout *layout = new QGridLayout( this );
    //layout->addWidget( m_titleLabel, 0, 0 );
    layout->addWidget( m_panelStack, 1, 0 );
}

void PanelStack::back()
{
    if( m_history.count() <= 1 )
        return; // Cannot go back past the first panel

    m_history.pop();

    showTopPanel();
}


void PanelStack::home()
{
    if( m_history.count() <= 1 )
        return; // Cannot go home if there are no panels, and is already home if there is only one panel

    while( m_history.count() > 1 )
        m_history.pop();

    showTopPanel();
}

Did you check the content of QStack.h ?

I did check the content of Qstack.h

Hi, hmmm files look ok, but just checking:
Almost at the end of newsalepanel.h I don't see any }; I mean shouldn't it be:

...

    QDataWidgetMapper *mapper;
};

Thank you. I have found the error. I've missed a bracket and a semi colon in one of my header file
