QTableView add Rows renders wrong
-
First, I'd check with a delegate like the Star Delegate sample to see if everything goes well with custom painting. Then I'd check with just a rendering a combo box without any modification to the painter.
-
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_ViewsI 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.
-
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?
-
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.
