[arjita]

If I include following line in program then the program is finished unexpectedly:
layout()->setSizeConstraint(QLayout::SetFixedSize);
Otherwise it is workin fine ...plz tell..

If you fix the wrong quotes in main.cpp and sortdialog.cpp your program still does not compile. You need to implement SortDialog::setColumnRange() (it's in the book).

Your program crashes at that line because layout() returns 0. You need to apply a layout to the dialog in Designer.

Oh I did implement setColumnRange() in my code ... bt I think forgot in the code that I have attached here...and as far as problem with layout()->setSizeConstraint(QLayout::SetFixedSize); is concerned i think forgot to rename the layout in Qt designer....I ll see that thanks...

Now my code is working fine with no error but the dialog box doesn't hold resize property... here I am giving the snapshots of what is being displayed..

#include <QtGui>
#include "sortdialog.h"
SortDialog::SortDialog(QWidget *parent)
    : QDialog(parent)
{
    setupUi(this);
    secondaryGroupBox->hide();
    tertiaryGroupBox->hide();
    formlayout->layout()->setSizeConstraint(QLayout::SetFixedSize);
    setColumnRange('A', 'Z');
}
void SortDialog::setColumnRange(QChar first, QChar last)
{
    primaryColumnCombo->clear();
    secondaryColumnCombo->clear();
    tertiaryColumnCombo->clear();
    secondaryColumnCombo->addItem(tr("None"));
    tertiaryColumnCombo->addItem(tr("None"));
    primaryColumnCombo->setMinimumSize(secondaryColumnCombo->sizeHint());
    QChar ch = first;
    while (ch <= last) {
        primaryColumnCombo->addItem(QString(ch));
        secondaryColumnCombo->addItem(QString(ch));
        tertiaryColumnCombo->addItem(QString(ch));
        ch = ch.unicode() + 1;
    }
}

#include <QtGui>
#include "sortdialog.h"
SortDialog::SortDialog(QWidget *parent)
    : QDialog(parent)
{
    setupUi(this);
    secondaryGroupBox->hide();
    tertiaryGroupBox->hide();
    formlayout->layout()->setSizeConstraint(QLayout::SetFixedSize);
    setColumnRange('A', 'Z');
}
void SortDialog::setColumnRange(QChar first, QChar last)
{
    primaryColumnCombo->clear();
    secondaryColumnCombo->clear();
    tertiaryColumnCombo->clear();
    secondaryColumnCombo->addItem(tr("None"));
    tertiaryColumnCombo->addItem(tr("None"));
    primaryColumnCombo->setMinimumSize(secondaryColumnCombo->sizeHint());
    QChar ch = first;
    while (ch <= last) {
        primaryColumnCombo->addItem(QString(ch));
        secondaryColumnCombo->addItem(QString(ch));
        tertiaryColumnCombo->addItem(QString(ch));
        ch = ch.unicode() + 1;
    }
}

To copy to clipboard, switch view to plain text mode 

in above code formlayout is the grid layout of the form..
I also changed my ui file as attached...
sortdialog.ui
Plz someone tel me what should I do to have resizable property...
