hide() or load data on constructor in QDialog?
-
Hi !.
I have a QMainWindow that has a QMenu , there is a QAction that opens a QDialog window, this QDialog window has a QTableWidget, it reads from a std::vector<MyObject>, where MyObject is an object that contains QString fields that will be loaded into the table...
What is the most orthodox way to follow:
-
show() QDialog ... load data table on constructor from std::vector use it then close(), this will delete the QDialog window pointer so each time i open this will need constructor to read data
-
show QDialog ... load data table from std::vector then hide() (it will load data once, but will be kept on memory)
-
any other way?
Thanks.

Do you want to trade speed or space? How big is the data, how often do you show/hide dialog? Your choice! -

That is a good point, i'm really not sure how much data is going my client manipulate... the only think i know is speed is more important... so i guess hide() makes more sense to me right now..
The good point is i confirmed with your answer that both ways are fine.
Thanks.!
