Various functions for QSplitter

• To insert the widget in splitter at a specific position

splitter.insertWidget( 3, button );

• To set the Orientation of Qsplitter

QSplitter splitter(Qt::Vertical/Qt::Horizontal);

Various functions for QTextEdit

• To set font Italic in QTextBox.

QTextEdit *editor1 = new QTextEdit;
editor->setFontItalic(1);

• To set the Document title.For a newly-created, empty document, this property contains an empty string.

textEdit->setDocumentTitle("Hello");

The QTextEdit class provides a widget that is used to edit and display both plain and rich text.

QTextEdit *editor1 = new QTextEdit;
QTextEdit *editor2 = new QTextEdit;
QTextEdit *editor3 = new QTextEdit;

A QSplitter is a widget that contains other widgets. The child widgets of a QSplitter widget are automatically placed side by side (or one below the other) in the order in which they are created, with splitter bars between adjacent widgets.

QSplitter splitter(Qt::Horizontal);
splitter.addWidget(editor1);
splitter.addWidget(editor2);
splitter.addWidget(editor3);

Make widget visible.

splitter.show();

Source Code

#include "splitter.h"
#include<QSplitter>
#include<QTextEdit>
#include<QHBoxLayout>
splitter::splitter(QWidget *parent)
    : QWidget(parent)
{
	QHBoxLayout *layout=new QHBoxLayout(this);
	QTextEdit *editor1 = new QTextEdit("Qt rocks",this);
	QTextEdit *editor2 = new QTextEdit("for",this);
	QTextEdit *but1=new QTextEdit("hello",this);
	QSplitter splitter(Qt::Vertical);
	splitter.addWidget(editor1);
	splitter.addWidget(editor2);
	splitter.addWidget(but1);
	layout->addWidget(editor1);
	layout->addWidget(editor2);
	layout->addWidget(but1);
        setStyleSheet("* { background-color:rgb(0,0,0);color:rgb(255,255,255); padding: 7px}}");
 
	setLayout(layout);
        showMaximized();
}
 
splitter::~splitter()
{
  // No need to delete any object that has a parent which is properly deleted.
}
