Qt signal slot multithread

You provide the code - it is good. But I can not understand what you want? In mainwindow.h file put slots in the public section: @ public slots: void mySlot1();. Qt Signal Slot Multithread; Qt invokemethod vs signal slotRe: Multi-threading behavior of signals and slots. QML and Qt Quick QML multithread client with c++ integration QML as @LeLev said from another thread I should use the signal/slot, and it works correctly now.

Since the start button is the only widget that can cause this slot to be invoked, we simply disable it before starting the thread, avoiding problems with re-entrancy. Have you tried to do anything with a QTimer that is on the stack of a thread moved class? Half a megabyte, which is more than enough. I tried LeLev method, So first I made another class named backend, and registered it to my qml with:. Actually what I want to do is to upload a large file to the server. Thanks, moveToThread works before any thread is started.

In my tcphandler class I make an object from QTCPSocket, and then move it to a differnet thread but it gave me the error: Cannot create children for a parent that is in a different thread.

Hi PouryaTorabi and welcome,. The idea here is to make a wraper class that lives in the main thread and forwards signals and function calls to your threaded tcp class. I tried LeLev method, So first I made another class named backend, and registered it to my qml with:. Then in one of backend's functions I create an instance of the TCPhandler class and moved it in a new thread:.

In my tcpHandler class I create an instance of the Qtcpsocket. The part which cause it is:. Since mydata is some large datas. So I tried to write the threads to see if the socket's thread has change or not, and saw that the thread of the created socket is the same as the main thread but the tcpHandler is different.

I tried to force the socket to move to tcpHandler's thread by using:. The qml engine must also be in the main thread, so what option do I have? Actually what I want to do is to upload a large file to the server. TcpThread and tcp must be members of your backend class. The part which cause it is: PouryaTorabi To avoid problems and conflicts, refrain from stack variables and constructer initialization in the class that is supposed to be moved to another thread. Sockets are special, you can't create them in some thread and then move them to another.

The Good The Surface Studio has a fantastic inch screen with excellent color, mounted on smooth hinges that fold down to an artist-friendly angle. The excellent Surface Pen stylus returns and the new Surface Dial shows promise. Every model has good-to-great dedicated graphics hardware. The Bad Surface Studio is extremely expensive, and doesn't include the flashy Dial accessory by default. It skips newer graphics chips that support VR hardware.

Support for the Dial is limited right now, and even compatible programs don't always use it in a practical way. A couple of front-mounted USB ports or a Thunderbolt connection would've been nice.

Now comes the Surface Studio, the company's first desktop PC. Surface Studio is easily the most attention-grabbing new PC design of the season, even if most of its individual ideas -- external control knobs, tabletop PCs -- have been seen before in different contexts. The Studio is a inch all-in-one Windows PC, with a screen that folds all the way down to a low drafting table angle of 20 degrees. Its better-than-4K 4,x3,pixel resolution touchscreen can display a very wide color range Adobe sRGB or P3 color spaces.

It works with the same Surface Pen that came with last year's Surface Pro 4 and Surface Book, but a new optional wireless knob input device -- dubbed Surface Dial -- is what really made the Surface Studio feel different.
