Sep 20, 2010 · So, no other events or the UI are blocked like normal windows sleep function does. As a bonus, we added the CancelSleep function to allows another part of the program to cancel the "sleep" function. What we liked about this is that it lightweight, reusable and is completely self contained. 5. I think the problem is that in your SLOT definition you put a variable name "depart" in, which is not correct. The SLOT and SIGNAL definitions must only have the function name and types. So: connect (chp3, SIGNAL (clicked ()), this, SLOT (prendpixel1 (Pixel))); BTW I think it is also space sensitive, so SLOT (anotherfn (Pixel, Pixel)) would.

AFAIK you cannot connect an argumentless signal to a slot with arguments. How would the metaobject system guess what to pass to the slot? Edit: for completeness, the doc clearly says "The signature of a signal must match the signature of the receiving slot. (In fact a slot may have a shorter signature than the signal it receives because it can ignore extra arguments.)". Well, I've searched this many times in Google, and still I can't solve it, so I ask for some help. I've seen the documentation, and I think this is the way to declare a custom slot: My H file: @ #ifndef ACTIVIDADESTIC_H #define ACTIVIDADESTIC_H #include.

. 1 Answer. The signature of a signal must match the signature of the receiving slot. (In fact a slot may have a shorter signature than the signal it receives because it can ignore extra arguments.) You are connecting signal and slot with different signatures. While connecting you are giving a variable to slot instead of just puting the type of.

MediaProgressManager * manager = new MediaProgressManager (); QProgressBar * progress = new QProgressBar (window); QObject:: connect (manager, SIGNAL (tick (int)), progress, SLOT (setValue (int))); You can see that you have to provide a signature inside the SIGNAL and SLOT macro, providing the type of the values that are passed through the signals. It is safe to mutually connect the replot slot with any of those two signals on two QCustomPlots to make them replot synchronously, it won't cause an infinite recursion. If a layer is in mode QCPLayer::lmBuffered (QCPLayer::setMode), it is also possible to replot only that specific layer via QCPLayer::replot. See the documentation there for.
