The return value is the number of the clicked button. ## First button is number 0. ## ## eg: ret = tk_dialog("Warning", "You are about to erase the whole disk. Are ## you sure?", "questhead", 0, "No","Yes", "Have I asked you something?") ## will return 0 if the first button (No) is clicked, etc. ## ## there are 6 meaningfull bitmap names: error, hourglass, info, questhead, ## question and warning.
