QT多线程类数组同时开启几十个线程怎么实现(qt,开发技术)

我们先定义一个线程类类：textTread

texttread.h

view source#define TEXTTREAD_H

04.#include <<a href="https://blog.51cto.com/user_index.php?action=addblog_new" target="_blank" class="keylink">QT</a>hread>

05.

06.classtextTread :public<a href="https://blog.51cto.com/user_index.php?action=addblog_new"target="_blank"class="keylink">QT</a>hread

07.{

08.Q_OBJECT

09.public:

10.textTread();

11.voidrun();

12.signals:

13.voidsendGUIThreadData(QString str);//向主线程通信的信号

14.publicslots:

15.voidGetGUIThreadID(intmThreadID);//接受主线程通讯过来数据的槽

16.private:

17.intThreadID;

18.};

19.

20.#endif // TEXTTREAD_H

再来看 texttread.cpp

view sourceprint?

01.#include"texttread.h"

02.#include <qDebug>

03.textTread::textTread()

04.{

05.}

06.voidtextTread::run()

07.{

08.qDebug() << tr("Thread is Open,ThreadID : %1").arg(ThreadID);

09.//You can do anything in here 嗨嗨拽两句鸟文

10.}

11.voidtextTread::GetGUIThreadID(intmThreadID)//接受主线程通讯过来的数据

12.{

13.ThreadID = mThreadID;

14.}

再看在GUI主线程实现50个线程的代码：

view sourceprint?

01.constintLENGTH = 50;

02.

03.textTread *tread;

04.tread =newtextTread[LENGTH];

05.for(inti=0;i<=LENGTH-1;i++){

06.connect(this,SIGNAL(SendGUIThreadID(int)),&tread[i],SLOT(GetGUIThreadID(int)));

07.connect(&tread[i],SIGNAL(sendGUIThreadData(QString)),this,SLOT(GetGUIThreadData(QString)));

08.emit SendGUIThreadID(i);

09.tread[i].start();

10.}

声明类的指针数组。

然后循环绑定信号与槽，最后循环用Start()运行线程，注意此处new 出的类数组，后面用的是.而不是-> 。
