gtk:label-text (label)

label -- a gtk:label widget
text -- a string with the text

The gtk:label-text function fetches the text from a label, as displayed on the screen. The (setf gtk:label-text) function sets the text.

It overwrites any text that was there before. This will also clear any previously set mnemonic accelerators. This does not include any embedded underlines indicating mnemonics or Pango markup. See the gtk:label-label function.
