how to change msleep seconds in QThread

[sdastagirmca]

hi All,

i want to change my msleep seconds by QSlider.According to the value change in slider ,the seconds should be changed.

class MyThread :public QThread
 
{
 
Q_OBJECT
 
private:
 
bool m_bToSuspend;
 
QWaitCondition m_waitCondt;
 
public :
 
QMutex mutex;
 
QWaitCondition wcCondition;
 
int count,iSeconds;
 
MyThread()
 
{
 
count=0;
 
m_bToSuspend=false;
 
 
iSeconds=1000;
 
}
 
void run()
 
{
 
QMutex waitMutex;
 
//qDebug()<<"count : "<<count;
 
for (int i=0;i<count;)
 
{
 
msleep(iSeconds);
 
qDebug()<<iSeconds;
 
emit changeValue(i);
 
// pause the simulator
 
if (m_bToSuspend)
 
{
 
waitMutex.lock();
 
m_waitCondt.wait(&waitMutex);
 
waitMutex.unlock();
 
}
 
i+=3;
 
}
 
}
 
signals:
 
void changeValue(int i);
 
public slots:
 
void getCount (int pCount)
 
{
 
count=pCount;
 
}
 
void suspend();
 
void startThread();
 
void getTimer(int pval)
 
{
 
   iSeconds=pval*100;
 
}
 
};

class MyThread :public QThread

{

Q_OBJECT

private:

bool m_bToSuspend;

QWaitCondition m_waitCondt;

public :

QMutex mutex;

QWaitCondition wcCondition;

int count,iSeconds;

MyThread()

{

count=0;

m_bToSuspend=false;


iSeconds=1000;

}

void run()

{

QMutex waitMutex;

//qDebug()<<"count : "<<count;

for (int i=0;i<count;)

{

msleep(iSeconds);

qDebug()<<iSeconds;

emit changeValue(i);

// pause the simulator

if (m_bToSuspend)

{

waitMutex.lock();

m_waitCondt.wait(&waitMutex);

waitMutex.unlock();

}

i+=3;

}

}

signals:

void changeValue(int i);

public slots:

void getCount (int pCount)

{

count=pCount;

}

void suspend();

void startThread();

void getTimer(int pval)

{

   iSeconds=pval*100;

}

};

In this getTimer() slot is used by the slider control.
connect(slider,SIGNAL(valuchanged(int)),thread,SLO T(getTimer()));
The thread is started after creating a instance of the class MyThread;

Hi, it should be

connect(slider,SIGNAL(valueChanged(int)),thread,SLOT(getTimer(int)));

connect(slider,SIGNAL(valueChanged(int)),thread,SLOT(getTimer(int)));

To copy to clipboard, switch view to plain text mode 

note the int in getTimer.

hi Ginsengelf,

iSeconds value is not updating in run event loop.While the thread is running i want to change the msleep seconds.
