QDialog, show() works but not close()

[tamara3011]

Hi All,

I am updating some existing code and need to close a qDialog that is opened with show(). But when I try to connect to slots, close(), hide() finished(), etc. I get the error
error C2039: 'closeEvent' : is not a member of 'QObject'

Is it possible to close a dialog box without subclassing? Everything is already working and I don't want to re-write the code.

I have a ui QDialog file created with designer holding multiple widgets. When I press my button it opens a modeless dialog window. All I want to add is that when I press another button it will close the dialog, or hide I don't really care. I can close it using the X button, but want to be able to close it when the user does something in the code that renders the dialog no longer valid,

The actual code is large, but here is what I am trying to do. Hope it helps.

in MyApp.h
#include ui_fullSizeImage.h"
#include "ui_myapp.h"
...
Ui::MyApp            m_ui;
Ui::FullSizeDialog  m_fullSizeDialog
 
 
in MyApp.cpp  which is a QMainWindow class
 
  m_ui.setupUi(this);
  m_fullSizeDialog.setupUi(new QDialog(this, Qt::WindowMaximizeButtonHint));
 
// show dialog
  connect(m_ui.m_fullScreenButton,
          SIGNAL(clicked()),
          m_fullSizeDialog.m_dialogWidget->parent(),
          SLOT(show()));

in MyApp.h
#include ui_fullSizeImage.h"
#include "ui_myapp.h"
...
Ui::MyApp            m_ui;
Ui::FullSizeDialog  m_fullSizeDialog


in MyApp.cpp  which is a QMainWindow class

  m_ui.setupUi(this);
  m_fullSizeDialog.setupUi(new QDialog(this, Qt::WindowMaximizeButtonHint));
  
// show dialog
  connect(m_ui.m_fullScreenButton,
          SIGNAL(clicked()),
          m_fullSizeDialog.m_dialogWidget->parent(),
          SLOT(show()));

To copy to clipboard, switch view to plain text mode 

And I want to add

// close dialog,  wont compile.
  connect(m_ui.m_fullScreenCloseButton,
          SIGNAL(clicked()),
          m_fullSizeDialog.m_dialogWidget->parent(),
          SLOT(close()));

// close dialog,  wont compile.
  connect(m_ui.m_fullScreenCloseButton,
          SIGNAL(clicked()),
          m_fullSizeDialog.m_dialogWidget->parent(),
          SLOT(close()));

To copy to clipboard, switch view to plain text mode 

Thanks for your help

While this is a seriously weird setup, it should work.

You could also keep the pointer to the dialog in a member instead of relying that "parent()" on another object returns it.

Cheers,
