I am using PyQT5 to design a GUI and I can’t seem to open the window. I’ve read almost all the forums discussing my issue.

In this working example, I have a SQL Lite db (“in memory”). The QtableView is setup on a QSortFilterProxyModel with one of the column, “product” which can be filtered via user selection through a QComboBox.

In the example code below, I have a CustomWidget consisting of a main label (red) on top, and sub label (yellow) on bottom – and I instantiate several of those in a scroll area:

What you see is the MRE of one of my projects.
Three tables in a container.
The problem is that if I launch it using the 4:3 monitor at home the three tables are displayed correctly. If I launch it from the laptop the last table is not displayed.
I thought about using a scrollArea, but to no avail.

What you see below is my situation

I have a QTableWidget with a checkbox on each row, problem is the user is able to check multiple rows. I have tried to add the setExclusive method but it doesn’t appear to be working. I have searched on here and found one similar example but following their lead didn’t work either.

I have a condition where I want a comboBox inside the Rectangle user drawings. For the user to select which sort of object it is.
Below diagram should give you a better understanding

I’m using this piece of script to get a splash screen followed by the main program.
The splash screen works correctly: it shows the image for the set time after which it exits and the main screen begins which however shows its screen after about 2.5/3 seconds.
What I would like is to synchronize the splashscreen output with the appearance of the main program screen
