Widget offering masked numerical entry and/or selection.
None.
A GtkSpinButton is a widget offering a displayed numerical value which can be incremented or decremented within a pre-set range by the user's clicking on one of two arrow buttons, or by using the Up and Down arrow keys.
The display area is a GtkEntry; the spinbutton object currently provides the only built-in means of masking input in GTK+. If you want to restrict the user to the values displayed rather than allowing keyboard input, call set_editable() from the spinbutton.
