QDialog ?

[allensr]

I've got a simple app (no functionality yet, just laying it out) that opens with a dialog box with 2 buttons. If you hit one button another Dialog box opens and when you hit OK/Cancel from that Dialog control goes back to the original dialog. If you hit the other button the otherDialog box opens but when you hit OK/Cancel from that dialog, once it closes out and the original dialog box comes back into view, I can't click on the original dialog anymore. It's like it's grayed out. I just hear a ding in the background each time I try to click anywhere on it. I can't see anything that I'm doing differently between the 2. Are there any parenting issues involved here?

in my header for the main dialog box

class cMainWindowDlg : public QDialog, public Ui::cMainWindowDlg
{
   Q_OBJECT
 
public:
   cMainWindowDlg(QWidget * parent = 0);
   virtual ~cMainWindowDlg();
   void setupUi();
 
private slots:
   // Automatically connected slots.  Note these slots follow the naming convention
   // on_objectName_signalName()
 
   void on_mOkButton_clicked();
   void on_mCancelButton_clicked();
   void on_mLaborCategoryButton_clicked();
   void on_mContractButton_clicked();
 
private:
   cLaborCategoryDlg * mLaborCategoryDlg;
   cContractDataQueryDlg * mContractDataDlg;
}; // cMainWindowDlg

class cMainWindowDlg : public QDialog, public Ui::cMainWindowDlg
{
   Q_OBJECT

public:
   cMainWindowDlg(QWidget * parent = 0);
   virtual ~cMainWindowDlg();
   void setupUi();

private slots:
   // Automatically connected slots.  Note these slots follow the naming convention
   // on_objectName_signalName()

   void on_mOkButton_clicked();
   void on_mCancelButton_clicked();
   void on_mLaborCategoryButton_clicked();
   void on_mContractButton_clicked();

private:
   cLaborCategoryDlg * mLaborCategoryDlg;
   cContractDataQueryDlg * mContractDataDlg;
}; // cMainWindowDlg

How do you "close" that otherDialog in your code?

[rajesh]

do you want to open multiple dialog by clicking first button?

[allensr]

I close each dialog the same way.

The one that "works"

////////////////////////////////////////////////////////////////////////////////
void cLaborCategoryDlg::on_mOkButton_clicked()
{
   accept();
} // cLaborCategoryDlg::on_mOkButton_clicked
 
////////////////////////////////////////////////////////////////////////////////
void cLaborCategoryDlg::on_mCancelButton_clicked()
{
   reject();
} // cLaborCategoryDlg::on_mCancelButton_clicked

////////////////////////////////////////////////////////////////////////////////
void cLaborCategoryDlg::on_mOkButton_clicked()
{
   accept();
} // cLaborCategoryDlg::on_mOkButton_clicked

////////////////////////////////////////////////////////////////////////////////
void cLaborCategoryDlg::on_mCancelButton_clicked()
{
   reject();
} // cLaborCategoryDlg::on_mCancelButton_clicked

To copy to clipboard, switch view to plain text mode 

The one that doesn't:

////////////////////////////////////////////////////////////////////////////////
void cContractDataQueryDlg::on_mOkButton_clicked()
{
   accept();
} // cContractDataQueryDlg::on_mOkButton_clicked
 
////////////////////////////////////////////////////////////////////////////////
void cContractDataQueryDlg::on_mCancelButton_clicked()
{
   reject();
} // cContractDataQueryDlg::on_mCancelButton_clicked

////////////////////////////////////////////////////////////////////////////////
void cContractDataQueryDlg::on_mOkButton_clicked()
{
   accept();
} // cContractDataQueryDlg::on_mOkButton_clicked

////////////////////////////////////////////////////////////////////////////////
void cContractDataQueryDlg::on_mCancelButton_clicked()
{
   reject();
} // cContractDataQueryDlg::on_mCancelButton_clicked

[jacek]

Have you reimplemented accept(), reject() or exec() in cContractDataQueryDlg?

[allensr]

No, I haven't.

[allensr]

I figured it out. In the dialog box that wasn't closing out properly, I had several checkboxes, and for some reason, one of the checkboxes had Qt::ApplicationModal set

Anyway, set it to Qt::NonModal like all of the rest, and it works fine now.

Thanks to all who replied.

Do you know that these slots are redundant? You might have done:

connect(mOkButton, SIGNAL(clicked()), this, SLOT(accept()));
connect(mCancelButton, SIGNAL(clicked()), this, SLOT(reject()));

connect(mOkButton, SIGNAL(clicked()), this, SLOT(accept()));
connect(mCancelButton, SIGNAL(clicked()), this, SLOT(reject()));

Or even make the connection graphically in Designer.
