QTabWidget, QTabBar, double-click the tabText

[jcr]

Hello,

I am using a QTabWidget and, once a tab has been selected, I would like a click or double-click on its tabText or tabIcon to trigger a certain function. Ideally, the click to select that tab in the first place would not trigger the function. Any idea on how to proceed? Thanks.

You could try to install an event filter on QTabBar.

Take a look at:

void QTabBar::mousePressEvent (QMouseEvent *e)
int QTabBarPrivate::indexAtPos(const QPoint &p) const

in src/gui/widgets/qtabbar.cpp.

This is something I used in my code, feel free to use and abuse. It does not handle double click, but it gives you a direction to your problem.



void qmdiTabBar::mousePressEvent ( QMouseEvent * event )
{
if (event->button() == Qt::MidButton)
{
int tabCount = count();
for( int i=0; i<tabCount; i++ )
{
if (tabRect(i).contains(event->pos()))
{
emit middleMousePressed(i, event->pos());
break;
}
}
}
else if (event->button() == Qt::RightButton)
{
int tabCount = count();
for( int i=0; i<tabCount; i++ )
{
if (tabRect(i).contains(event->pos()))
{
emit rightMousePressed(i, event->pos());
break;
}
}
}

QTabBar::mousePressEvent(event);
}
