QT中如何让一个按钮单击后更新一个TextEdit

[huntrose]

我的程序如下，想让BUTTON CLICKED后让pTextEdit2显示pTextEdit1的内容，不知道哪里做错了
才用QT，不是很了解，希望大家帮忙看看

#include <QT/QApplication.h>
#include <QT/QPushButton.h>
#include <QT/QTextEdit.h>

#include <string>

class MyWidget : public QWidget
{
private:
	QTextEdit *pText1,*pText2;
	QPushButton *pButton;
public:
	MyWidget(QWidget* parent);
	~MyWidget();
public slots:
	void buttonPressed();
};

MyWidget::MyWidget(QWidget* parent)
:QWidget(parent)
{
	setFixedSize(300,300);
	
	pText1 = new QTextEdit("Edit1",this);
	pText2 = new QTextEdit("Edit2",this);
	pButton = new QPushButton("Button",this);
	
	pText1->resize(100,100);
	pText1->setGeometry(0,0,100,100);
	
	pText2->resize(100,100);
	pText2->setGeometry(120,0,100,100);
	
	pButton->resize(100,30);
	pButton->setGeometry(10,200,100,30);
	
	QObject::connect(pButton,SIGNAL(clicked()),this,SLOT(buttonPressed()));
}

MyWidget::~MyWidget()
{
	delete pText1;
	delete pText2;
	delete pButton;
}

void MyWidget::buttonPressed()
{
	pText2->setText(pText1->toPlainText());
}

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    
    QWidget window;    
    window.resize(400,400);

	MyWidget my_widget(&window);
	my_widget.setGeometry(10,10,300,300);

    window.show();
    return app.exec();
}

不太清楚,有可能你获取TEXT1的为空
