set_prefer_wide_layout

Whether to prefer horizontal button layout.

`AdwAlertDialog` can present buttons horizontally or vertically depending on available space, how many buttons there are and how wide they are.

By default it will prefer to stack buttons vertically at medium sizes.

Set to `TRUE` to prefer horizontal layout in these cases instead. This will make the dialog slightly wider as well.

Vertical layout may still be used if the dialog would get too wide otherwise.

Does nothing with just one button, or when the buttons are already horizontal.

Parameters:

this	an alert dialog
prefer_wide_layout	whether to prefer wide layout
