problem in Qt4 dialog

[spirit]

ok, the problem is in Disp:: openDatumForm in this line

...
if(datumform.exec() == QDialog::Accepted)
...

...
if(datumform.exec() == QDialog::Accepted)
...

when you close this dialog by Alt+F4 then the result of exec will be QDialog::Rejected and you pass this block

{
   DatumVal = Datumno_Val;
   XVal = Xdatum_Val;
   YVal = Ydatum_Val;
   ZVal = Zdatum_Val;
   datuminitial();  
}

{
   DatumVal = Datumno_Val;
   XVal = Xdatum_Val;
   YVal = Ydatum_Val;
   ZVal = Zdatum_Val;
   datuminitial();  
}

there is two ways:
add a "OK" button in that dialog and connect signal QPushButton::clicked with QDialog::accept and leave this code unchanged

void Disp::openDatumForm()
{
	DatumForm datumform(this);
	datumform.move(35, 90);
	if(datumform.exec() == QDialog::Accepted) {
		DatumVal = Datumno_Val;
		XVal = Xdatum_Val;
		YVal = Ydatum_Val;
		ZVal = Zdatum_Val;
		datuminitial();
	}
}

void Disp::openDatumForm()
{
	DatumForm datumform(this);
	datumform.move(35, 90);
	if(datumform.exec() == QDialog::Accepted) {
		DatumVal = Datumno_Val;
		XVal = Xdatum_Val;
		YVal = Ydatum_Val;
		ZVal = Zdatum_Val;
		datuminitial();
	}
}

the second ways is: to use code like this

void Disp::openDatumForm()
{
	DatumForm datumform(this);
	datumform.move(35, 90);
	datumform.exec();
	DatumVal = Datumno_Val;
	XVal = Xdatum_Val;
	YVal = Ydatum_Val;
	ZVal = Zdatum_Val;
	datuminitial();
}

void Disp::openDatumForm()
{
	DatumForm datumform(this);
	datumform.move(35, 90);
	datumform.exec();
	DatumVal = Datumno_Val;
	XVal = Xdatum_Val;
	YVal = Ydatum_Val;
	ZVal = Zdatum_Val;
	datuminitial();
}

in this case there is no need to add extra button in the dialog, but you also lose checking of the dialog acception or rejection.

I tried with both the ways but i am not able to display the values in the Disp form same problem. During the start of the applications the lineEdits sholud display 0.000 and that is not happening here is start up code snippet..

Disp::Disp (QDialog *parent)
    :QDialog(parent)
{
 
        setupUi(this);
 
    qDebug( "Init Function ( During StartUp)" );
 
    xlineEdit->setText("0.000");
 
    ylineEdit->setText("0.000");  
 
    zlineEdit->setText("0.000");
 
    decimals_mm = 3;
    decimals_inch = 4;
    datuminitial();
}

Disp::Disp (QDialog *parent)
    :QDialog(parent)
{

        setupUi(this);
	
    qDebug( "Init Function ( During StartUp)" );
  
    xlineEdit->setText("0.000");
 
    ylineEdit->setText("0.000");  
  
    zlineEdit->setText("0.000");
   
    decimals_mm = 3;
    decimals_inch = 4;
    datuminitial();
}

Please see my code attached and help us.

I don't understand what you need...

When i run my application all the lineEdits in Disp Form should display 0.000 this is done by

xlineEdit->setText("0.000");
ylineEdit->setText("0.000");
zlineEdit->setText("0.000");

xlineEdit->setText("0.000");
ylineEdit->setText("0.000");
zlineEdit->setText("0.000");

but when i run the application it is displaying bank in all the lineEdits.
