gtk:cell-renderer-progress-text (object)

object -- a gtk:cell-renderer-progress object
text -- a string for the label which will be drawn over the progress bar

The accessor for the text slot of the gtk:cell-renderer-progress class gets or sets the label which will be drawn over the progress bar. Setting this property to nil causes the default label to be displayed. Setting this property to an empty string causes no label to be displayed. The gtk:cell-renderer-progress implementation is deprecated since 4.10. Please do not use it in newly written code.
