Qt如何显示正文

1、这里的话，我直接跟大家代码吧！#include "QtGuiApplication1.h"QtGuiApplication1::QtGuiApplication1(QWidget *parent)    : QMainWindow(parent), ui(new Ui:

2、:QtGuiApplication1Class()) {     ui->setupUi(this); } void QtGuiApplication1::on_push_clicked() {     QString s = QString::number(56);     ui->label->setText(s); 

3、}     h: #pragma once #include#include "ui_QtGuiApplication1.h" class QtGuiApplication1 

4、 public QMainWindow {     Q_OBJECT public:     QtGuiApplication1(QWidget *parent = Q_NULLPTR);     

5、private slots:     void on_push_clicked(); private:     Ui::QtGuiApplication1Class *ui; };
