嘿,所以这段代码在今天早些时候运行良好。突然我开始收到这个非常奇怪的编译器错误。任何人,这是头文件:
#ifndef MAINWINDOW_H
#define MAINWINDOW_H
//Includes
#include <QMainWindow>
#include <QWidget>
#include <QPushButton>
#include <QLayout>
namespace Ui {
class MainWindow;
}
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();
private:
//Useful Functions
void create_buttons ();
void create_layout ();
//Variables
QPushButton* Button1 ;
QPushButton* Button2 ;
QPushButton* Button3 ;
QPushButton* Button4 ;
QHBoxLayout* ButtonContainer ;
QVBoxLayout* MainContainer ;
QWidget* MainWidget ;
}
#endif // MAINWINDOW_H
和cpp文件:
#include "mainwindow.h"
#include "ui_mainwindow.h"
MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent)
{
// create_layout();
create_buttons();
}
MainWindow::~MainWindow()
{
//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
}
void MainWindow::create_buttons()
{
Button1 = new QPushButton("Button1",this);
Button2 = new QPushButton("Button2",this);
Button3 = new QPushButton("Button3",this);
Button4 = new QPushButton("Button4",this);
ButtonContainer->addWidget(Button1);
ButtonContainer->addWidget(Button2);
ButtonContainer->addWidget(Button3);
ButtonContainer->addWidget(Button4);
}
void MainWindow::create_layout()
{
MainWidget = new QWidget;
ButtonContainer = new QHBoxLayout;
MainContainer = new QVBoxLayout;
MainContainer->addLayout(ButtonContainer);
MainWidget->setLayout(MainContainer);
setCentralWidget(MainWidget);
}
这是编译器错误:C2236:意外的“类”“ QEventPrivate”。您忘记了和“;”吗?
我一生无法理解发生了什么,如果有人可以,我将不胜感激。
最佳答案
您在MainWindow
类声明的末尾缺少分号
QPushButton* Button4 ;
QHBoxLayout* ButtonContainer ;
QVBoxLayout* MainContainer ;
QWidget* MainWidget ;
} // <- Missing semi-colon
关于c++ - 涉及QEventPrivate的编译器错误?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/18755278/
