gtk:file-chooser-native-cancel-label (object)

object -- a gtk:file-chooser-native object
label -- a string for the custom label or nil for the default

The accessor for the cancel-label slot gets or sets the custom label text for the cancel button.

If characters in label are preceded by an underscore, they are underlined. If you need a literal underscore character in a label, use "__" (two underscores). The first underlined character represents a keyboard accelerator called a mnemonic. Pressing Alt and that key activates the button. The gtk:file-chooser-native implementation is deprecated since 4.10. Use the gtk:file-dialog implementation instead.
