good to install the qt libraries libraries alguns works well with me but with other states that are not present
#include <qapplication.h>
#include <qhbox.h>
#include <qslider.h>
#include <qspinbox.h>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QHBox *hbox = new QHBox(0);
hbox->setCaption("Enter Your Age");
hbox->setMargin(6);
hbox->setSpacing(6);
QSpinBox *spinBox = new QSpinBox(hbox);
QSlider *slider = new QSlider(Qt::Horizontal, hbox);
spinBox->setRange(0, 130);
slider->setRange(0, 130);
QObject::connect(spinBox, SIGNAL(valueChanged(int)),
slider, SLOT(setValue(int)));
QObject::connect(slider, SIGNAL(valueChanged(int)),
spinBox, SLOT(setValue(int)));
spinBox->setValue(35);
app.setMainWidget(hbox);
hbox->show();
return app.exec();
}
well this book is proof of qt, well tells me that the library is not present qhbox.h, now well to compile with qt ==> qmake-projet ==> == qmake> make, works great can be compiled without problems, but in the C:: B tells me that the library is not present, I am using windows xp sp2
