PW_LABEL_TEXT
Set the text of the label. The parameter should be of type "char *". The text should not contain '\n'.
PW_LABEL_UNDERLINE
Indicate that the specified letter has to be underlined in the label. This normally indicates that the letter can be used to select the item which is labelled. This tag needs one parameter, the character which has to be underlined. The label will underline the character with the same case if it exists in the text, or otherwise it will underline the same character in different case. (This is consistent with the fact that keystrokes are case dependent in ProWesS).
