Hello, every one. I'm Phuong, I come from VietNam. I have a problem: I have a thread and I want to update many interface by signal and slot? my thread is a
variable(public) in interface 1, and I have function(public) getThread() to return this thread. And I want to update interface 2 use this thread(by signal and slot). But it is not update? Can you tell me solve?
Thanks!

Maybe you just want to use moveToThread() method? All slots are invoked in the slot's instance's thread.

Thank you for reply. I'm new member of QT, My English so bad! I still use a thread but, this thread is not an attribute of interface 1, I define it as a global variable( can use for many class), and this thread is updated two interface. Thanks for reply!
