#include "widget.h"
Widget:: Widget(QWidget *parent)

// QPushButton *quit = new QPushButton( "Quit",this );
// quit->setGeometry( 62, 40, 75, 30 );
//quit->setFont( QFont( "Times", 18, QFont::Bold ) );
// connect( quit, SIGNAL(clicked()), qApp, SLOT(quit()) );
ui.setupUi(this); //有错误的一行
}

[解决办法]
建议将ui声明成指针:
UI::m_window *ui;
构造函数相应增加初始化项:
Widget:: Widget(QWidget *parent)
: QWidget(parent),ui(new Ui::m_window)//不要忘记ui的初始化
{
...
}
