问题描述
我需要立即开始并从Qml File中停止QThread扩展类.有什么解决办法吗?这是我的课:
I need to Start immediately and stop then a QThread extended class from Qml File. Is there any solution for that? here is my class :
class SerialManager : public QThread
{
Q_OBJECT
public:
CircularList<unsigned char> buffer_[2];
signals:
void dataReady(short *value,int len,unsigned short sample);
protected:
void run();
};
推荐答案
如果您具有如下的SerialManager:
if you have SerialManager like this:
class SerialManager : public QThread
{
Q_OBJECT
public:
CircularList<unsigned char> buffer_[2];
signals:
void dataReady(short *value,int len,unsigned short sample);
protected:
void run();
};
在main.cpp中添加以下代码:
in main.cpp add bellow code:
qmlRegisterType<SerialManager>("Device",1,0,"Serial");
然后在您的qml中执行以下操作:
then in your qml do this:
Component.onCompleted: {
thread.start()
}
Component.onDestruction:
{
thread.quit()
}
