showIfNeeded()

static

Determine data directory.

Let the user choose if the current one doesn't exist. Let the user configure additional preferences such as pruning.

Returns

true if a data directory was selected, false if the user cancelled the selection dialog.

Note

do NOT call global gArgs.GetDataDirNet() before calling this function, this will cause the wrong path to be cached.

Use selectParams here to guarantee Params() can be used by node interface.

If current default data directory does not exist, let the user choose one.
