#Qt update gui from worker thread software
Hardware and Software Programming Digital Media Community Center Home. Forums DaniWeb IT Discussion Community Forums. Hey i heard that there is something called qt signals you can use it to change the GUI out side the main thread coz when i try to change it. QRunnable and execute it using another entity offered by Qt. Model->setData(model->index(0, 0), subject) // Gui could modify model here! Model->setData(model->index(0, 1), sender) // Gui could modify model here! Model->setData(model->index(0, 2), date). But if the View class you are using can do any autonomous modifications (like drag and drop rearrangement), then it could break the expectations of worker thread code, such as: model->insertRow(0) // Gui could modify model here! Despite the synchronization overhead, I imagine this approach could avoid crashes.
