Overview

A QGroupBox box is a QWidget for grouping other widgets. It provides a frame, a title and a keyboard shortcut. The title is on top, the keyboard shortcut moves keyboard focus to one of the group box's child widgets.

It is used to make a specific group of same kind or different kind of widget

QGroupBox *group=new QGroupBox();

Preconditions

• Download and install the Qt SDK

Various Function

• To set the title of QGroupBox.

group->setTitle("&Nokia Phones");

• To Align the title that is "Right,Left,center".

group->setAlignment(Qt::AlignHCenter);

• To set The layout of QGroupBox.

QVBoxLayout *layout=new QVBoxLayout();
QGroupBox *group=new QGroupBox();
group->setLayout(layout);

• To make the title checkable,So that until or unless the title checkBox value is "false" the QGroupBox is disable and if it is "true" the QGroupBox is enable

group->setCheckable(true);

Remember

• You have to first of all set the layout of the QGroupBox then after we have to add this widget in our main window.
