Qt Signals



  • Hi,
    I have a doubt regarding qt signals,Is it possible to block signals according to some conditions. like, I am using two signals contentSizeChanged() and loadStarted() in my program connecting to two different slots.Is it possible to make like If loadStarted()signal emitted, contentSizeChanged() signal should not work?

    Hi,

    Do you mean the slot connected to contentSizeChanged should do nothing ?
    If so, just use a flag that's set when the slot connected to loadStarted is called and and in the slot connected to contentSizeChanged don't do anything if the flag is set.

    Hope it helps



  • Hii...

    You can use-->bool QObject::blockSignals ( bool block )

    If block is true, signals emitted by this object are blocked (i.e., emitting a signal will not invoke anything connected to it). If block is false, no such blocking will occur.

    The return value is the previous value of signalsBlocked().
