Something I quickly put up to demonstrate how to define a custom QTabBar, which shows an image always center aligned (The default QTabBar aligns the icon to the left always).
The custom tab bar class, here only showing one tab being added, the same can be extended to more tabs
// header file not shown here
- include "MyTabBar.h"
- include <QLabel>
MyTabBar::MyTabBar(QWidget* parent)
: QTabBar(parent)
{
this->addTab(QString());
QLabel* lbl;
lbl = new QLabel();
lbl->setPixmap(QPixmap(QString::fromUtf8("../../popup/5.png")));
lbl->setAlignment(Qt::AlignCenter);
// can set a larger size below too, but the icon is always center aligned
lbl->setFixedSize(16,16);
this->setTabButton(0, QTabBar::LeftSide, lbl);
}
The custom tab widget class, which uses the custom tab bar
- include "MyTabWidget.h"
- include "MyTabBar.h"
- include <QDebug>
MyTabWidget::MyTabWidget(QWidget *parent)
: QTabWidget(parent)
{
this->setGeometry(QRect(10, 10, 300, 250));
MyTabBar* bar;
bar = new MyTabBar();
this->setTabBar(bar);
}
Calling it from mainwindow.cpp as follows:
MyTabWidget *mytab;
mytab = new MyTabWidget(centralWidget());
