How to close QDialog

jsulm

@gabor53 You did not post code for your dialogs. How are Additem and review implemented?
Do you have any buttons user can press to close the dialogs?
Either accept() or reject() must be called.
And this code should actually show Additem dialog as a modal dialog:

mAddItem->exec ();

So, at least this dialog is closed, right? Else you cannot proceed with anything else.

@jsulm
You are right that one closes.
Here are the codes:
mainwindow.cpp
additem.cpp
review.cpp
Thank you for your help.

@jsulm
There is a button on the review.ui they can click and close. One of my issue is that is it possible to click on close on review.ui and close both review and additem?

jsulm

You can call accept() or reject() on additem when you close review.

@jsulm
Would you please show me how?

First of all it will be quite unexpected behaviour if you would close addItem when user closes review! As user I would expect that if I close review only review is closed. If I understand your code correctly the flow is: add an Item via addItem, from addItem open review to review the item (optional?), then close review, close addItem. So, closing child dialog should not close parent dialog.

But if you really want to do it this way then just call

mAddItem->accept();

You would need to pass the pointer to AddItem instance to review.

Unfortunately

mAddItem->accept();

doesn't do anything.
The surrounding code:

   QMessageBox::StandardButton reply;
   reply = QMessageBox::information(this, "Confirmation","<b><font size='16' color='green'>The Friend is added to the database. Would you like to add more Friends?</font></b>",QMessageBox::Yes | QMessageBox::No);

       Additem *mAdditem = new Additem;

   if(reply == QMessageBox::Yes)
   {
       qDebug() << "Yes was clicked.";
   }
   else
   {
        mAdditem->accept ();
   }

@gabor53 What is this code supposed to do?
You create an instance of Additem, but you do not show it - at least you do not call mAdditem->show() or mAdditem->exec()

@jsulm
It supposed to close additem.

jsulm

@gabor53 But you do not show additem - how can it be closed?

Im trying to close the additem dialog that originally generated the review. So it was called from mainwindow.

I created a new project with 2 dialogs, the sources are mainwindow.cpp and dialog.cpp.
The code in dialog.cpp looks like this:

#include "dialog.h"
#include "ui_dialog.h"

Dialog::Dialog(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::Dialog)
{
    ui->setupUi(this);
}

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

void Dialog::message()
{
    QMessageBox::StandardButton reply;
       reply = QMessageBox::information(this, "Confirmation","<b><font size='16' color='green'>Do you want to close the 2nd window?</font></b>",QMessageBox::Yes | QMessageBox::No);

       if(reply == QMessageBox::Yes)
       {
           qDebug() << "Yes was clicked. Close 2nd.";
           this->reject();
       }
       else
       {
           qDebug()  << "No was clicked. Don't close 2nd.";
       }
}

void Dialog::on_pushButton_clicked()
{
    message();
}

When I click yes, it does what I want, it closes dialog. When I use the same code in my original application, it does nothing (no error message either). What can cause this completely different behavior? Thank you.
