<H3>Description</H3> |
||||
<P>A combination of the input widget and a menu button. |
||||
The user can either type into the input area, or use the |
||||
menu button chooser on the right, which loads the input area |
||||
with predefined text. Normally it is drawn with an inset box |
||||
and a white background. |
||||
<P> |
||||
The application can directly access both the input and menu |
||||
widgets directly, using the <A HREF=#Fl_Input_Choice.menubutton>menubutton()</A> |
||||
and <A HREF=#Fl_Input_Choice.input>input()</A> accessor methods. |

second form sets the contents using the index into the menu |

which you can set as an integer. Setting the value effectively |

'chooses' this menu item, and sets it as the new input text, |
