QT编程
make后出现如下错误：
-pipe -DQWS -fno-exceptions -fno-rtti -Wall -W -O2 -fno-default-inline -DNO_DEBUG -I/home/x86-qt/qt-2.3.7/include -o form1.o form1.cpp

make: *** [form1] Error 1
这是什么原因？？？
我代码为：（include <*.h>文件都包含了，"using namespace std;" 也都加了）
------------------Form1.h-----------------------
class Form1:public QWidge
{
}
-------------------------------------------------------
------------------Form1.cpp-------------------------------------------------
Form1::Form1( QWidget* parent, const char* name, WFlags fl )
: QWidget( parent, name, fl )
{
}
Form1::XXX()
{
QTabWidget* TabWidget = new QTabWidget( mw );
TabWidget->setGeometry( QRect( 0, 0, 320, 240 ) );
Tab* tab = new Tab( TabWidget, "tab" );
tab->setBackgroundColor(QColor(60,140,120));
TabWidget->insertTab( tab, "menu1" );
}
----------------------------------------------------------------------------------------
-------------------------------tab.h-----------------------
class Tab:public QWidget
{
public:
Tab( QWidget* parent, const char* name );
~Tab();
protected slots:
void paintEvent(QPaintEvent*);
};
--------------------------------------------------------------------------------------
-------------------------------tab.cpp----------------------------------------------
Tabluo::Tabluo( QWidget* parent ,const char* name)
:QWidget(parent,name,fl)
{
}
void Tabluo::paintEvent(QPaintEvent*)
{
QPainter paint;
paint.begin(this);
paint.setPen(QPen(blue,10,QPen::DashLine));
paint.drawRect(20,20,160,160);
paint.end();
}
----------------------------------------------------------------------------------------
