[solved] qtoolbar and qstackwidget
-
I have a toolbar with icons at the left. I'd like to change the "perspective" on the mainwindow when I click on a toolbar icon.
But:
toolbar icon has only signal triggered or triggered(bool) and qstackwidget has only slot setCurrentIndex(int).
Of course this is not working :)Any idea for replacement of qstackwidget? Or some solution?

You should use a "QSignalMapper":http://qt-project.org/doc/qt-4.8/qsignalmapper.html

Can you send me a code snippet how can I solve this?
In this case the QSignalMapper is not clear me.

This should do:
@#include <QtGui/QtGui>int main(int argc, char** argv)
{
QApplication app(argc, argv);QMainWindow mw;
mw.setMinimumSize(400,300);
mw.show();
mw.raise();QSignalMapper mapper;
QToolBar* tb = new QToolBar();
QAction* tab;
tab = tb->addAction(QObject::tr("Tab 1"));
mapper.setMapping(tab, 0);
mapper.connect(tab, SIGNAL(triggered(bool)), SLOT(map()));tab = tb->addAction(QObject::tr("Tab 2"));
mapper.setMapping(tab, 1);
mapper.connect(tab, SIGNAL(triggered(bool)), SLOT(map()));tab = tb->addAction(QObject::tr("Tab 3"));
mapper.setMapping(tab, 2);
mapper.connect(tab, SIGNAL(triggered(bool)), SLOT(map()));mw.addToolBar(Qt::TopToolBarArea, tb);
QStackedWidget* stack = new QStackedWidget;
QLabel* lbl;
lbl = new QLabel(QObject::tr("TAB 1"));
lbl->setAlignment(Qt::AlignCenter);
stack->addWidget(lbl); // index: 0
lbl = new QLabel(QObject::tr("TAB 2"));
lbl->setAlignment(Qt::AlignCenter);
stack->addWidget(lbl); // index: 1
lbl = new QLabel(QObject::tr("TAB 3"));
lbl->setAlignment(Qt::AlignCenter);
stack->addWidget(lbl); // index: 2
// Connect the mapper
stack->connect(&mapper, SIGNAL(mapped(int)), SLOT(setCurrentIndex(int)));mw.setCentralWidget(stack);
return app.exec();
