Slot called twice when button pressed

[PetQter]

I created new project with button in MainWindow before my last post because I wanted to exclude if it is something in my code. Result is the same.
Try please to comment both connect with released and clicked events and leave only connect with pressed handler and put breakpoint into pressed handler. Does not stops your code on breakpoint two times ?
Try it please pushing button several times, in my case on first attempt it stops once and after F5 (continue) it does not stop again. But on several next attempts on every click it stops on breakpoint and after continue it stops on breakpoint second time.

Hi
Only stops once here pr click. No matter how many times i click and f5.

just tested it with pressed, same behavior as clicked in the video

I believe you. On my side it is probably depending on some internal dll responsible for events like mouse pressed. Maybe combination of Qt library, QtCreator version and Win 10 version. I must check it on another Windows developer's machine but it takes some days to have opportunity. I'd like to know if it has the same problem. I will write result to this post then.

Sorry for the necro, but I was having this same issue and I discovered it was because I was inheriting from another QDialog that I had made. Figured I would post and explain the issue...

Steps to reproduce...

• Make a base QDialog (let's call it BaseDialog).
• Add a button to BaseDialog.
• In QtDesigner, right click the button and click "Go to slot"->"clicked(bool)".
• Add some debugging to the created slot so you can see it is being hit (qDebug("Slot Hit");).
• Make another QDialog (SecondaryDialog).
• Force SecondaryDialog to inherit from BaseDialog instead of QDialog (just edit the .h file of SecondaryDialog).
• Create an instance of SecondaryDialog programmatically.
• Run your program and click the button inside SecondaryDialog, it will be hit twice...

I managed to solve this by manually adding the connect call in the BaseDialog constructor instead of depending on Qt to do it for me...

Please provide a minimal, compilable example of the issue. You for sure did the connect twice.

@KidTrent
Most times people say slot hit multiple times turns out they have multiple connects. Not great idea to use the "named" auto-connections from Creator.

Oh, I see @Christian-Ehrlicher has written this. Post an example.

@SGaist I had done the same mistake of connecting the signal to a slot twice. I used pyqt5, and I had used the connect twice! Thus, calling the same message box element twice!

@Rohit_Athithya some things are meant to happen 😁
Glad you found the trick.
