Basic Program unexpectedly finished
-
I'm trying to run a pretty basic program which implements some tabs, which have buttons on their pages. I have it written out in both C++ and done int the design .ui. However, when I try to run the program I get the message: "The program has unexpectedly finished." Does anyone have any idea what is causing this in the code below?
@
#include <QtGui/QApplication>
#include "mainwindow.h"
#include <QPushButton>
#include <QTabWidget>
#include <QVBoxLayout>
#include <QGridLayout>
#include <QTranslator>QWidget *backView();
QVBoxLayout *videoSelect();int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.resize(1280, 242);
QTabWidget tabs;
QWidget *view = backView();
QVBoxLayout video = videoSelect();
tabs.addTab(view, "Rear View");
tabs.addTab((QWidget)video, "Camera Select");
//w.addWidget(tabs);
tabs.show();
w.show();
return a.exec();
}QWidget *backView() {
QPushButton *tbd = new QPushButton("TBD");
return tbd;
}QVBoxLayout *videoSelect() {
QVBoxLayout *camChoice = new QVBoxLayout;
QGridLayout *cameras = new QGridLayout;
for(int i = 0; i < 16; i++){
QPushButton button = new QPushButton("Camera " + i);
cameras->addWidget(button, i / 4, i % 4);
}
camChoice->addWidget((QWidget)cameras);
//vid =
//camChoice->addWidget(vid);
return camChoice;
}

Try adding:
@
w.setCentralWidget(tabs);
@You will probably need to change it into a pointer, though. And maybe reparent, if it is not done automatically. Also, try debugging to see where exactly does it fail.

Your friendly neighborhood debugger should be able to tell you the exact spot where the program is crashing. That would probably be a good place to start looking. :-)
