Thread freezing GUI

[TheGrimace]

In the Main GUI, I create an instance of DoThis GUI and pass a pointer to each tab that is created.

Each tab then passes that pointer to its QThread

PSUEDOCODE:
 
 
Each Tab's QThread Run Method:
run{
// create new objects
object_1 = new object1;
object_2 = new object2;
//each of these signals is called once per request
connect(object2,signal,object1,slot)
connect(object1,signal,object2,slot)
connect(DoThis,signal,object1,slot)
connect(object1,signal,DoThis,slot)
object2->startTCPListener();
object2->startUDPListener();
exec();
//disconnect and delete everything
}

connect(object1,signal,object2,slot)

object2->startTCPListener();
object2->startUDPListener();
exec();
//disconnect and delete everything
}

Object1 then has a slot like the following:

readwriteLocker.lockforWrite();
 
listofObjects->add(new File_Thread);
uniqueID = // a new unique ID
listofObjects->at(listofObjects->count()-1)->setUniqueID(uniqueID);
 
readwriteLocker.unlock()
readwriteLocker.lockforRead()
 
for(int i=0; listofObjects->count()>i ; i++)
{
    if(listofObjects->at(i)->uniqueID == uniqueID)
    {
         listofObjects->at(i)->start();
    }
}
readwriteLocker.unlock()

readwriteLocker.lockforWrite();

listofObjects->add(new File_Thread);
uniqueID = // a new unique ID
listofObjects->at(listofObjects->count()-1)->setUniqueID(uniqueID);

readwriteLocker.unlock()
readwriteLocker.lockforRead()

for(int i=0; listofObjects->count()>i ; i++)
{
    if(listofObjects->at(i)->uniqueID == uniqueID)
    {
         listofObjects->at(i)->start();
    }
}
readwriteLocker.unlock()

The File_Thread finished signal is connected to a similar function that deletes the object.

Here is what the File_Thread run method looks like:

run{
booleanRunning = true;
find_File();        //This is where everything is done, emits, io accesses, everything
                        //This is also where the gui slows down and becomes unresponsive
booleanRunning = false;
}

run{
booleanRunning = true;
find_File();        //This is where everything is done, emits, io accesses, everything
                        //This is also where the gui slows down and becomes unresponsive
booleanRunning = false;
}

Thank You all for your interest and help.

I hope this makes the problem more clear.
