qt - Temporarily block signals between two QObjects -

-

i generically , temporarily block signals between 2 qobjects without modifying other signals/slots behavior, , without knowing contexts.

something qobject::blocksignals(bool), acting between 2 qobjects.

that is, implementing following signalblocker::blocksignals(bool) function:

class signalblocker {  public:   signalblocker(qobject *sender, qobject *receiver) :     msender(sender), mreceiver(receiver) {}   void blocksignals(bool block);  private:   qobject *msender, *mreceiver; }

it possible disconneting , re-connecting objects, first list of signals/slots have stored. introspection methods don't seem powerful enough achieve (i looked @ qmetaobject , qsignalspy without success).

qt have no capabilities disable signal-slot pair only. try workaround:

struct signaldisabler {     signaldisabler(const qobject *sender, const char *signal, const qobject *receiver, const char *member)         : sender(sender)         , signal(signal)         , receiver(receiver)         , member(member)     {         qobject::disconnect(sender, signal, receiver, member);     }      ~signaldisabler()     {         qobject::connect(sender, signal, receiver, member);     }      const qobject *sender;     const char *signal;     const qobject *receiver;     const char *member; };
