Qt如何显示正文

1、这里的话，我直接跟大逛罹为垴家代码吧！#include "QtGuiApplication1.h"旌忭檀祉 QtGuiApplication1::QtGuiApplication1(QWidget *parent) : QMainWindow(parent), ui(new Ui:

2、:QtGuiAppli罕铞泱殳cation1Class()) { ui->setupUi(this); 魈胺闹臣} 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; };
