I developed an embedded app using Qt based on LinuxImageV2.4 that is running fine. I linked all QPushButton signals (clicked) to its respectively slot clicking right-mouse-button, and the app was running fine.
After I recompiled the same app based on Qt on LinuxImageV2.6, and execute the app, I receive the message “QMetaObject::connectSlotsByName: No matching signal for …”.
I read in the forum about this error: “… that is the “trade-off” for the “automatism” of this form of connect. Which is why any professional Qt developer will recommend not to use it (too fragile)”.
Is it true? I must back down to use automatic signal-slot link by right-mouse-button, and use “connect function” to do it, ok?
