Closing a dialog using a button

[srohit24]

Hi

I need to close the dialog box using a button. I have 4 line edits and i need to save the values into a variable before closing the dialog.

I have a mainwindow and a dialog.

this is my code, to open the dialog b4 the main window.

void desktop::newdevice()
{
  QDialog dlg;
  Ui::newdevice newui;
  newui.setupUi(&dlg);
 
  identityreaddata();
  dlg.setWindowTitle("Title");
  newui.statuslabel->setText("Please enter the details");
 
  //if(dev_email == '\0' || dev_serialno == '\0'|| dev_devicename == '\0' )
  {
      if(dlg.exec()== QDialog::Accepted);
      {
         devicename = newui.devnameEdit->text();
         password = newui.passEdit->text();
         email = newui.emailEdit->text();
         slno = newui.slnoEdit->text();
         qDebug () << "device name"<<devicename;
         qDebug () << "password"<<password;
         qDebug () << "email"<<email;
         qDebug () << "slno"<<slno;
         connect(newui.updateButton, SIGNAL(clicked()),SLOT (QDialog::close()));
 
      }

void desktop::newdevice()
{
  QDialog dlg;
  Ui::newdevice newui;
  newui.setupUi(&dlg);

  identityreaddata();
  dlg.setWindowTitle("Title");
  newui.statuslabel->setText("Please enter the details");

  //if(dev_email == '\0' || dev_serialno == '\0'|| dev_devicename == '\0' )
  {
      if(dlg.exec()== QDialog::Accepted);
      {
         devicename = newui.devnameEdit->text();
         password = newui.passEdit->text();
         email = newui.emailEdit->text();
         slno = newui.slnoEdit->text();
         qDebug () << "device name"<<devicename;
         qDebug () << "password"<<password;
         qDebug () << "email"<<email;
         qDebug () << "slno"<<slno;
         connect(newui.updateButton, SIGNAL(clicked()),SLOT (QDialog::close()));

      }

To copy to clipboard, switch view to plain text mode 

but when i press the update button, the dialog doesnt close. I have to press the x button on the right top corner to close it.

Can somebody help me with this??

Move line 23 to line 6

[srohit24]

did that. No change. I still have to close it manually with the X button.

Shouldn't you

whatever->setAttribute(Qt::WA_DeleteOnClose)
connect(newui.updateButton, SIGNAL(clicked()), this, SLOT(close()));

whatever->setAttribute(Qt::WA_DeleteOnClose)
connect(newui.updateButton, SIGNAL(clicked()), this, SLOT(close()));

I guess it should be

connect(newui.updateButton, SIGNAL(clicked()), &dlg, SLOT(close()));

connect(newui.updateButton, SIGNAL(clicked()), &dlg, SLOT(close()));

To copy to clipboard, switch view to plain text mode 

after you have setup the gui, but you can do it also inside the Designer...
