我在Qt C ++应用程序中有一个QQuickwidget,在该应用程序中我已经加载了一个QML文件(main.qml),并且使用QAction(actionstart)和C ++函数,我必须加载另一个与前一个稍有不同的QML文件(main1.qml)。在同一个QQuickWidget对象上。
我能够做到这一点,但是我的第二个QML文件在QQuickwidget的中间部分和其他地方重叠了。
我这样做是为了停止2个QML文件的重叠,但是并没有完全成功。在Guiapplication.h文件的公共部分中定义了count3 = 1。
void GuiApplication::on_actionstart_triggered()
{
if (count3 == 1)
{
set_animation();
count3 = 2;
}
}
用于加载第一个QML文件(main.qml)的C ++函数
void GuiApplication::rolling_animation()
{
QQuickView *quickWidget=new QQuickView();
QWidget *contain = QWidget::createWindowContainer(quickWidget,this);
contain->setMinimumSize(1008,349);
contain->setMaximumSize(1008,349);
contain->setFocusPolicy(Qt::TabFocus);
quickWidget->setSource(QUrl("qrc:/Resources/main.qml"));
ui->horizontalLayout_6->addWidget(contain);
}
用于加载第二个QML文件(main1.qml)的C ++函数
void GuiApplication::set_animation()
{
QQuickView *quickWidget=new QQuickView();
QWidget *Contain = QWidget::createWindowContainer(quickWidget,this);
Contain->setMinimumSize(1008,349);
Contain->setMaximumSize(1008,349);
Contain->setFocusPolicy(Qt::TabFocus);
quickWidget->setSource(QUrl("qrc:/Resources/main1.qml"));
ui->horizontalLayout_6->addWidget(Contain);
//ui->horizontalLayout_9->invalidate();
//ui->horizontalLayout_9->removeWidget(quickWidget_4);
}

根据是否要保存的QML状态来进行隐藏,有以下几种选择:
#include <QtQuickWidgets>
class Widget: public QWidget
{
Q_OBJECT
public:
Widget(QWidget *parent=nullptr):
QWidget(parent),
m_widget(new QQuickWidget)
{
m_widget->setResizeMode(QQuickWidget::SizeRootObjectToView);
QPushButton *button1 = new QPushButton("show 1");
QPushButton *button2 = new QPushButton("show 2");
QHBoxLayout *lay = new QHBoxLayout(this);
QVBoxLayout *vlay = new QVBoxLayout;
vlay->addWidget(button1);
vlay->addWidget(button2);
lay->addLayout(vlay);
lay->addWidget(m_widget);
connect(button1, &QPushButton::clicked, this, &Widget::show1);
connect(button2, &QPushButton::clicked, this, &Widget::show2);
show1();
}
private slots:
void show1(){
m_widget->setSource(QUrl("qrc:/main1.qml"));
}
void show2(){
m_widget->setSource(QUrl("qrc:/main2.qml"));
}
private:
QQuickWidget *m_widget;
};
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
Widget w;
w.show();
return a.exec();
}
#include "main.moc"
#include <QtQuickWidgets>
class Widget: public QWidget
{
Q_OBJECT
public:
Widget(QWidget *parent=nullptr):
QWidget(parent),
m_stacked_widget(new QStackedWidget)
{
for(const QString & url: {"qrc:/main1.qml", "qrc:/main2.qml"}){
QQuickWidget *widget = new QQuickWidget;
widget->setResizeMode(QQuickWidget::SizeRootObjectToView);
widget->setSource(QUrl(url));
m_stacked_widget->addWidget(widget);
}
QPushButton *button1 = new QPushButton("show 1");
QPushButton *button2 = new QPushButton("show 2");
QHBoxLayout *lay = new QHBoxLayout(this);
QVBoxLayout *vlay = new QVBoxLayout;
vlay->addWidget(button1);
vlay->addWidget(button2);
lay->addLayout(vlay);
lay->addWidget(m_stacked_widget);
connect(button1, &QPushButton::clicked, this, &Widget::show1);
connect(button2, &QPushButton::clicked, this, &Widget::show2);
show1();
}
private slots:
void show1(){
m_stacked_widget->setCurrentIndex(0);
}
void show2(){
m_stacked_widget->setCurrentIndex(1);
}
private:
QStackedWidget *m_stacked_widget;
};
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
Widget w;
w.show();
return a.exec();
}
#include "main.moc"
