Take a look at Signals and slots across threads. If you always use signals and slots to communicate with the worker thread, Qt handles the moveToThread for you if it's needed and you used the correct connection. Edit: I would guess the article's author was seeing his problem since he was...
Problem with signal-slot connection across threads [SOLVED]
Threads Events QObjects - Qt Wiki
Signals and Slots. Signals and slots are used for communication between objects. The signal/slot mechanism is a central feature of Qt and probably the part that differs most from other toolkits. In GUI programming we often want a change in one widget to be notified to another widget. Qt 4.6: Threads and QObjects Threads and QObjects. QThread inherits QObject. It emits signals to indicate that the thread started or finished executing, and provides a few slots as well. More interesting is that QObjects can be used in multiple threads, emit signals that invoke slots in other threads, and post events to objects that "live" in other threads. This is ... PyQt/Threading,_Signals_and_Slots - Python Wiki Since QRect and QImage objects can be serialized for transmission via the signals and slots mechanism, they can be sent between threads in this way, making it convenient to use threads in a wide range of situations where built-in types are used. Running the Example. We only need one more piece of code to complete the example: How to Use Signals and Slots - Qt Wiki Qt's signals and slots mechanism does not require classes to have knowledge of each other, which makes it much easier to develop highly reusable classes. Since signals and slots are type-safe, type errors are reported as warnings and do not cause crashes to occur.
Multithreaded programming for multicore architectures with
The code inside the Worker’s slot would then execute in a separate thread. However, you are free to connect the Worker’s slots to any signal, from any object, in any thread. It is safe to connect signals and slots across different threads, thanks to a mechanism called queued connections. Qt 线程 - wajh07的专栏 - CSDN博客 Signals and Slots Across Threads Qt 支持了几种信号（槽的连接方式）： Auto Connection ( 默认 ) ：如果如果信号的发送方与接收方是处于同一个线程，这个连接就是 ... Qt 4.8: Threads and QObjects Threads and QObjects. ... Signals and Slots Across Threads. Qt supports these signal-slot connection types: Auto Connection (default) If the signal is emitted in the thread which the receiving object has affinity then the behavior is the same as the Direct Connection. Otherwise, the behavior is the same as the Queued Connection." Threads and QObjects | 学步园
