Close button only for some tabs in Qt

Question

I am using Qt for an assignment I have for college, and I want to use QTabWidget to display a chat window much like Pidgin\'s. I want to make the \"group chat\" tab

Answer 1

The best way for adding a pushbutton to some tabs and not in other is to define a subclass of QTabWidget for taking the QTabBar that is a potected! The code below is tested and it works:

//TabWidget.h

#ifndef TABWIDGET_H
#define TABWIDGET_H
#include 

class TabWidget : public QTabWidget {
public:
    TabWidget(QWidget *parent);
    ~TabWidget();
    QTabBar *tabBar() const;
};
#endif  /* TABWIDGET_H */

//TabWidget.cpp

#include "TabWidget.h"
TabWidget::TabWidget(QWidget * p=0) : QTabWidget(p) {}

TabWidget::~TabWidget() {}

QTabBar * TabWidget::tabBar() const {return QTabWidget::tabBar();}

For using this subclass and create a new tab with a custom button you have to following this instructions ( ui->tabWidget is a QTabWidget with setClosableTabs=false):

TabWidget *t = (TabWidget *) ui->tabWidget;
t->addTab(new QWidget, "empty");
QTabBar *tab = t->tabBar();
QPushButton *b = new QPushButton();
b->setText("x");
tab->setTabButton(tab->count() -1, QTabBar::RightSide, b);
connect(b,SIGNAL(...),this,SLOT(...));
