[Qt-interest] Drawing rectangular

[Yuvaraj R]

Hi

 I have overrrided the QTextBrowser class like

*text_browser.h*


#ifndef TEXT_BROWSER_H

#define TEXT_BROWSER_H

#include <QTextBrowser>

#include <QPaintEvent>

class text_browser:public QTextBrowser

{

public:

text_browser(QWidget *parent=0);

void paintEvent(QPaintEvent *e);

};

#endif // TEXT_BROWSER_H


*text_browser.cpp*

#include "text_browser.h"

#include <QMessageBox>

text_browser::text_browser(QWidget *parent):QTextBrowser(parent)

{

}

void text_browser::paintEvent(QPaintEvent *e)

{

              e->accept();

}



you told that call base class paint event to paint the text browser.

any mistake is there in derived class of text_browser.


Sorry  English is not  my first language .
Thanks
