程序源码如下：
mylistwidgetitem.h文件：
#ifndef MYLISTWIDGETITEM_H#define MYLISTWIDGETITEM_H
#include <QWidget>#include <QCheckBox>#include <QRadioButton>#include <QListWidget>
#include <QListWidgetItem>#include <QToolButton>#include <QHBoxLayout>#include <QVBoxLayout>
class MyListWidgetItem : public QWidget{
Q_OBJECTpublic:
//explicit MyListWidgetItem(QString regionAddressArg,QList<QString> meterAddressListArg,QWidget *parent = 0);
MyListWidgetItem(QString regionAddressArg,QList<QString> meterAddressListArg,QWidget *parent);
private:
void initialMainWindow();
QString regionAddress;
QList<QString> meterAddressList;
signals:
public slots:
};
#endif // MYLISTWIDGETITEM_H
mylistwidgetitem.cpp文件
#include "mylistwidgetitem.h"
MyListWidgetItem::MyListWidgetItem(QString regionAddressArg,QList<QString> meterAddressListArg,QWidget *parent) : QWidget(parent){
regionAddress = regionAddressArg;
meterAddressList = meterAddressListArg;
initialMainWindow();
}
void MyListWidgetItem::initialMainWindow(){
QCheckBox *regionCheckBox = new QCheckBox(regionAddress,this);
regionCheckBox->setFixedSize(100,20);
QRadioButton *allSelectRadio = new QRadioButton(tr("全选"),this);
allSelectRadio->setFixedSize(60,20);
QRadioButton *againSelectRadio = new QRadioButton(tr("反选"),this);
againSelectRadio->setFixedSize(60,20);
QToolButton *headToolButton = new QToolButton(this);
headToolButton->setText(tr("隐藏"));
headToolButton->setFixedSize(50,20);
QHBoxLayout *headLayout = new QHBoxLayout;
headLayout->setMargin(0);
headLayout->setSpacing(0);
headLayout->addWidget(regionCheckBox);
headLayout->addWidget(allSelectRadio);
headLayout->addWidget(againSelectRadio);
headLayout->addStretch();
headLayout->addWidget(headToolButton);
QListWidget *meterAddListWidget = new QListWidget;
meterAddListWidget->setViewMode(QListView::IconMode);
meterAddListWidget->setResizeMode(QListView::Adjust);
for(int i = 0; i < 30; i++){
QListWidgetItem *item = new QListWidgetItem("112233445566");
item->setCheckState(Qt::Unchecked);
meterAddListWidget->addItem(item);
}
* //添加主布局
QVBoxLayout *mainLayout = new QVBoxLayout;
mainLayout->setMargin(0);
mainLayout->setSpacing(2);
mainLayout->addLayout(headLayout);
mainLayout->addWidget(meterAddListWidget);
this->setLayout(mainLayout);
}
mylistwidget.h文件：
#ifndef MYLISTWIDGET_H#define MYLISTWIDGET_H
#include <QWidget>#include "mylistwidgetitem.h"
class MyListWidget : public QWidget{
Q_OBJECT
public:
//explicit MyListWidget(QWidget *parent = 0);
MyListWidget(QWidget *parent);
~MyListWidget();
private:
QString *regionAddress;
QList<QString> meterAddressList1;
QList<QString> meterAddressList2;
signals:
public slots:
};
#endif // MYLISTWIDGET_H
mylistwidget.cpp文件：
#include "mylistwidget.h"#include "mylistwidgetitem.h"#include <QVBoxLayout>#include <QDebug>
MyListWidget::MyListWidget(QWidget *parent) : QWidget(parent){
meterAddressList1 << "112233445566" << "112233445566";
meterAddressList2 << "112233445566" << "112233445566";
qDebug() << "hello";
MyListWidgetItem *mylistWidgetItem1 = new MyListWidgetItem("112233445566",meterAddressList1,this);
MyListWidgetItem *mylistWidgetItem2 = new MyListWidgetItem("112233445577",meterAddressList2,this);
QVBoxLayout *mainLayout = new QVBoxLayout;
mainLayout->setMargin(0);
mainLayout->setSpacing(0);
mainLayout->addWidget(mylistWidgetItem1);
mainLayout->addWidget(mylistWidgetItem2);
this->setLayout(mainLayout);
}
MyListWidget::~MyListWidget(){}
mainwindow.cpp文件
#include "mainwindow.h"#include "ui_mainwindow.h"#include "mylistwidget.h"
MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow){
* ui->setupUi(this);
MyListWidget *myListWidget = new MyListWidget(this);
//myListWidget->sayHello();
* this->setCentralWidget(myListWidget);
}
MainWindow::~MainWindow()
{
delete ui;
}
运行之后出现如下提示：
F:\qtProject\myListWidget\myListWidget-build-desktop\debug\myListWidget.exe 启动中...
FTH: (3460): *** Fault tolerant heap shim applied to current process. This is usually due to previous crashes. ***
hello
F:\qtProject\myListWidget\myListWidget-build-desktop\debug\myListWidget.exe 退出， 代码: 0
我是想模仿QListWidget，QListWidgetItem两个类，创建自己的MyListWidget类和MyListWIdgetItem类。开始的时候成功了，后来运行时出错了。
请问是什么错误 。请各位指教

从头做吧。理论可行的，就是乱了点，你再item中又用了listwidget，这个不知想实现什么！
既然是学习，就别害怕出错，按自己的想法做吧。
