If you enter an age less than 18 or more than 80 and click on the button, a modal window will light up, but the button will be in the pressing mode and will turn dark, the same with RadioButton will only be highlighted in blue, is it possible to remove it somehow? When you click on another field, everything is fine

It works good but the only problem is that the videos are playing horizontally even if the video is a vertical video like 800 x 1600.
Is there any way to rotate videos either automatically or non-automatically?

I have written small program and would like to use underline format rather than selected text which is provided by QplainTextEdit
it work well, when i click mouse left click
But when i Use shift+left click, qplaintextedit select complete text and underline format gone.
I am trying to use only underline format and do not select text.
Expected behavior for shift+left click

If you send the event to the QPlainTextEdit then you can get the position and anchor of the selection and move them to cover the whole line.

Note that you could instead subclass QPlainTextEdit and reimplement mousePressEvent.
