Difference between transitional parent and parent in qt

Question

I am confused with the parent and temporary parent in qt.

• Is it possible to have both transitional and parental windows for the same window?
• For the top-level window (widgets such as pop-ups), are the parent settings set and the parent set to NULL?

Can you share a clear idea of ​​the parent and temporary parent in qt.
