QTableView add Rows renders wrong

Fuel

I tested it now with another Widgets and the Problem is still existing. So its not a Problem with only QComboBox. So it seems its a generally Problem with rendering. I have a similar Widget like in the StarDelegate Example and the Problem occurs. I tried not to modiy the QPainter but the Problem still exists. I also deleted the QTableView and created a new One.

Any other Ideas?

Hi
I newer say such issue with
https://wiki.qt.io/Combo_Boxes_in_Item_Views

I think you ask it to draw in wrong position with
painter->deviceTransform().map(option.rect.topLeft()))

You should check the y pos when its drawing wrongly.

Else it look ok from fast glance.

@mrjj said in QTableView add Rows renders wrong:

painter->deviceTransform().map(option.rect.topLeft()))

If i delete this part the Problem still exists. I took a look at your Link. In this Example there is no paint Event and im wondering. How does the Delegate know how to paint the Element?

If i remove the render Part the ComboBox isnt shown.

I think its a Problem with the Painter or the Renderfunction. Or perhaps something in my Layout.

Update:

It looks like its a Layout Problem. When i switch the Buttons to the Upper i dont have that Problem.

But why? Its a normal Gridlayout with a normal Row under the QTableView.

Can you show the code that setup everything including the buttons ?

I use the Designer. Cant show any Code, but only the XML Part which is not editable.

still have the problem. the rows renders outside of the tableview.

SGaist

Then can you provide a minimal compilable example so people can test that locally to help find the problem ?

I have made the Project Public in my Repository for some Days.

The Problem is in "Medikamentenplan" the below part. The Problem occurs in DoctorContact

I can't reproduce the defect you have on macOS.

On a side note, you should review that code base, I had to fix several errors before being able to run your application.

I installed a Virtual Machine with Linux and tested it. You are right, on other OS it isnt there. Maybe a Problem with Windows. But i dont know how to fix that now. Im using QT 5.9.1 and MSVC 2015 with 64-bit.

Could it be that the Problem is a Driver Problem?

SGaist

Maybe a glitch in the Windows style.

I have totally no Answer for that. Anyone has the Time to Check my Project over Teamviewer? If yes please write me a Message. We can do that with Teamspeak or Discord. Would be nice if you speak German.

I updated now to Qt 5.9.2 and the Problem is gone. Thx for everyone that tried to help.
