QT中如何让一个按钮单击后更新一个TextEdit
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();}
