Basically, I want a simple pushButton with a colorful text which when pressed exits the application.
Why cant I press PushButton in this simple program. I am using QT 4.6 on Arch x86_64.
#include <QtGui/QApplication>
#include <QLabel>
#include <QPushButton>
#include<QtGui>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QMainWindow *Main=new QMainWindow;
QPushButton *button = new QPushButton(Main);
QLabel *label = new QLabel(Main);
label->setText("<h2><i>Hello</i> ""<font color=red>Qt!</font></h2>");
label->setVisible(true);
QObject::connect(button, SIGNAL(clicked()),label, SLOT(clear()));
label->setAlignment(Qt::AlignCenter|Qt::AlignVCenter);
label->setWindowTitle("HelloWorld Test Program");
Main->show();
return a.exec();
}
