I want to connect a signal and slot with different parameters. My grid is made up of an array of QLineEdits, and here's how I'mNow, I'm just a beginner as a programmer, and I have no experience with Qt. I'm stuck in a strange situation. I want to connect a signal and slot with different parameters. [QT] signals/slots между тредами не понимаю —… Смущает что в сигнале/слоте передается указатель на локальную переменную image определенную в функции RenderThread::run(). Смущает потому что(на сколько я ничего не понимаю)при передаче сигнала между тредами не известно когда сигнал попадет в слот. Как работает механизм signal-slot QT, если нужно... —… Всем привет! Сам по себе принцып работы сигнал-слот в qt мне понятен (когда один объект передаёт сигнал в слот дургого объекта в одном потоке). Совсем запутался, когда попытался разобраться, как же мне из объекта, находящегося в одном потоке... [solved] Qt Signal/Slots in one class but emitted from … So the Qt GUI also implements this interface in order to receive the calls from the library.I assume that you are using the same object through pointers in different threads. Then this might be possible. However, the signal-slot mimic will more or less generate a direct function call which will be executed...

@Beginner: slots are functions. And the emits are placed on the currently running thread (be it GUI or worker). If there is a slot on a different thread that is connected to that signal it will run in the slot owner's thread when it is pulled off the event queue. – Adam W Jan 19 '10 at 17:26 |
Hello, I have written a code in which a slot is connected to multiple signals of different threads. Now there is a possibility of simultaneous emission of signals. So what I am thinking is, since the connection type is Qt::AutoConnection and senders and r...
So the Qt GUI also implements this interface in order to receive the calls from the library. The library runs several threads. Some of the processing of the GUI calls should not block the library from running. So the GUI class defines slots and signals, the signals are emitted in the implemented interface functions. c++ - How to signal a slot in another thread in Qt - Stack 2 Answers 2. You've got it backwards. A QThread is a thread handle, not a thread itself. If you want to run something in another thread, it belongs in a plain QObject that you move to a thread. You don't need to derive from QThread at all! You also shouldn't move a QThread's base QObject to the thread … user interface - Qt signaling across threads, one is GUI
