Reorganizing code

[Lost User]

Currently I have all these objects as a function / method "local " variables.
They can be used by other methods.

Would it make for "better code" if I declare them as class variables and instantiate them all in the class constructor - and be done with it?

They can be used throughout the app, so they "go away" when the app exits.

// add common configuration
BT_Configuration_MainWindow *BTCMW = new BT_Configuration_MainWindow();
BTCMW->show();

MainWindow\_Bluetoothctl \*MWB = new MainWindow\_Bluetoothctl();
MWB->show();

MWB->UpdateText();

BT\_Utility\_Library \*BTUL = new BT\_Utility\_Library();

There is no simple answer to such a question as the lifetime of a variable will depend on its usage and requirements. You need to analyse your code to decide what is best in each specific case.
