Find QObjects that insatlled event filter

[babu198649]

Hi all,
Is it possible to find the QObjects that installed event filter on an QObject.
Suppose there are two QObjects
QObject *objA;
QObject *objB;
b->installEventFilter(a);
// using object objA can i retrive the object objB which has installed event filter on it.

Thanks

I am not sure I follow.
B is the object you want to filter its events, and you know that, since you call b->installEventFilter().
In A, the eventFileter() method takes a parmeter with the object that currently triggered the incoming event, so you know its B (in A).

So what exactly is missing for you?

void foo(QObject *objA)
{
     QObject *objB = new QObject;
     objB->setEventFilter(objA);
}
 
int main()
{
     QObject *objA = new QObject;
     foo(objA);
     // after the call i want to get the list of QObjects who has set the eventFilters 
     // on objA, somthing like QList<QObject*> list = objA->getEventFilters();
     // Now list.at(0) will contain objB pointer.
}

void foo(QObject *objA)
{
     QObject *objB = new QObject;
     objB->setEventFilter(objA);
}

int main()
{
     QObject *objA = new QObject;
     foo(objA);
     // after the call i want to get the list of QObjects who has set the eventFilters 
     // on objA, somthing like QList<QObject*> list = objA->getEventFilters();
     // Now list.at(0) will contain objB pointer.
}

What do you need such a list for? Maybe there is a better approach to your problem?

Can't you do something like:

void foo(QObject *objA)
{
     QObject *objB = new QObject;
     objB->setEventFilter(objA);
     g_filterList.push_back(objB);
}

void foo(QObject *objA)
{
     QObject *objB = new QObject;
     objB->setEventFilter(objA);
     g_filterList.push_back(objB);
}
