passing GtkWidget parameters

I have a function that is connected to the "changed" signal for a combobox in gtk, which in turn calls another function read_button_config.

The read_button_config takes the main window, a combobox and a vcontainer which I had not declared globally as parameters

Which way is better for passing these parameters: - declaring the parameters globally - passing the parameters as a struct to the first function, and passing the struct members to the read_button_config function?

Please let me know why you think either is better, I want to know what is a better way for future development

The latter is the preferred way; that is the purpose of the user_data parameter to signal functions, after all.
Declaring them globally isn't bad. Rather, using the user_data is idiomatic. It's a bit harder since you have to manage the memory for the user_data yourself, but using user_data keeps your code modules more self-contained. You will need to decide what you want to do. – andlabs
