Question

Qt QStackedWidget局部分页遇到BUG，急急急，回答得好的有追加

代码如下，前面槽什么的都定义好了
QWidget(parent)
{
widget = new QWidget;
//左侧布局
QVBoxLayout *buttonLayout = new QVBoxLayout;
QWidget *leftWidget = new QWidget(this); //新建一个QWidget
buttonLayout->addWidget(leftWidget);
QPushButton *button1 = new QPushButton(leftWidget);
QPushButton *button2 = new QPushButton(leftWidget);
QPushButton *button3 = new QPushButton(leftWidget);
QPushButton *button4 = new QPushButton(leftWidget);
//右边布局
QGridLayout *rightLayout = new QGridLayout;
stackedWidget = new QStackedWidget;
rightLayout->addWidget(stackedWidget);
stackedWidget->addWidget(creat_1Page);
stackedWidget->addWidget(creat_2Page);
stackedWidget->addWidget(creat_3Page);
stackedWidget->addWidget(creat_4Page);
connect(button1, SIGNAL(clicked()),stackedWidget, SLOT(slot_1()));
connect(button2, SIGNAL(clicked()),stackedWidget, SLOT(slot_2()));
connect(button3, SIGNAL(clicked()),stackedWidget, SLOT(slot_3()));
connect(button4, SIGNAL(clicked()),stackedWidget, SLOT(slot_4()));
//双表关联
QHBoxLayout *mainLayout = new QHBoxLayout;
mainLayout->addLayout(buttonLayout);
mainLayout->addLayout(rightLayout);
mainLayout->addWidget(stackedWidget);
setLayout(mainLayout);
stackedWidget->showNormal();
}
Widget::~Widget()
{
}
void Widget::slot_1()
{
stackedWidget->setCurrentIndex(0);
}
void Widget::slot_2()
{
stackedWidget->setCurrentIndex(1);
}
void Widget::slot_3()
{
stackedWidget->setCurrentIndex(2);
}
void Widget::slot_4()
{
stackedWidget->setCurrentIndex(3);
}
void Widget::creatWidget_1()
{
creat_1Page = new QWidget;
}
void Widget::creatWidget_2()
{
creat_2Page = new QWidget;
}
void Widget::creatWidget_3()
{
creat_3Page = new QWidget;
}
void Widget::creatWidget_4()
{
creat_4Page = new QWidget;
}

不和你说过了是野指针的问题嘛，怎么不信呢？

Answer 2

你画个图吧,不知道你想要什么样的布局

追问

最外面是一个QHBoxlayout布局，里面左边是一个QVBoxlayout放按钮，里面右边是分页的。点击左边的按钮实现右边分页效果

追答

widget = new QWidget;
//左侧布局
QVBoxLayout * buttonLayout = new QVBoxLayout;

button1 = new QPushButton();
button2 = new QPushButton();
button3 = new QPushButton();
button4 = new QPushButton();

buttonLayout->addWidget(button1);
buttonLayout->addWidget(button2);
buttonLayout->addWidget(button3);
buttonLayout->addWidget(button4);

//右边布局
QStackedWidget * stackedWidget = new QStackedWidget;
stackedWidget->addWidget(creat_1Page);
stackedWidget->addWidget(creat_2Page);
stackedWidget->addWidget(creat_3Page);
stackedWidget->addWidget(creat_4Page);

//双表关联
QHBoxLayout *mainLayout = new QHBoxLayout;
mainLayout->addLayout(buttonLayout);
mainLayout->addWidget(stackedWidget);
widget->setLayout(mainLayout);
