First define here

Mr_Steve

Good morning. I have such a problem...

My help.cpp:

#include "help.h"
 
#include <ui_help.h>
 
Help::Help(QWidget *parent)
    : QDialog(parent)
    , ui(new Ui::Help)
{
    ui->setupUi(this);
 
    ui->beginDE->setMaximumDate( QDateTime::currentDateTime().date() );  //два dateEdit 
    ui->beginDE->setDate( QDateTime::currentDateTime().date() );
 
    ui->endDE->setMaximumDate( QDateTime::currentDateTime().date() );
    ui->endDE->setDate( QDateTime::currentDateTime().date() );
}
 
Help::~Help()
{
    delete ui;
}
 
QDate Help::begin() const
{
    return ui->beginDE->date();
}
 
QDate Help::end() const
{
    return ui->endDE->date();
}

My help.h:


#pragma once
 
#include <QDialog>
#include <QDateTime>
 
namespace Ui { class Help; }
 
class Help : public QDialog
{
    Q_OBJECT
public:
    explicit Help(QWidget *parent = 0);
    ~Help();
 
    QDate begin() const;
    QDate end() const;
 
private:
    Ui::Help * ui;
};

Main.cpp functional:

void MainWindow::view_help()
{
    if ( !checkPwd() ) return;
 
   Help * dialog = new Help( this );
    if ( dialog->exec() )
    {
        CrewTableViewerWidget * viewer = new CrewTableViewerWidget(this);
        viewer->setConfig( _editorConfig );
        viewer->setTimeInterval( dialog->begin(), dialog->end() );
        viewer->setCrew( getCrewIndex() );
        viewer->show();
    }
    dialog->deleteLater();
}

Also, there are .h and .cpp files that have the same functionality, but they work well.
What could be the problem?

@Mr_Steve make sure help.cpp is not added multiple times to your .pro file

Mr_Steve

@aha_1980 Thanks! It-s work.
