## @deftypefn  {Function File} {} uimenu (@var{property}, @var{value}, @dots{})
## @deftypefnx {Function File} {} uimenu (@var{h}, @var{property}, @var{value}, @dots{})
## Create a uimenu object and return a handle to it.  If @var{h} is omitted
## then a top-level menu for the current figure is created.  If @var{h}
## is given then a submenu relative to @var{h} is created.
##
## uimenu objects have the following specific properties:
##
## @table @asis
## @item @qcode{"accelerator"}
## A string containing the key combination together with CTRL to execute this
## menu entry (e.g., @qcode{"x"} for CTRL+x).
##
## @item @qcode{"callback"}
## Is the function called when this menu entry is executed.  It can be either a
## function string (e.g., @qcode{"myfun"}), a function handle (e.g., @@myfun)
## or a cell array containing the function handle and arguments for the
## callback function (e.g., @{@@myfun, arg1, arg2@}).
##
## @item @qcode{"checked"}
## Can be set @qcode{"on"} or @qcode{"off"}.  Sets a mark at this menu entry.
##
## @item @qcode{"enable"}
## Can be set @qcode{"on"} or @qcode{"off"}.  If disabled the menu entry
## cannot be selected and it is grayed out.
##
## @item @qcode{"foregroundcolor"}
## A color value setting the text color for this menu entry.
##
## @item @qcode{"label"}
## A string containing the label for this menu entry.  A @qcode{"&"}-symbol
## can be used to mark the @qcode{"accelerator"} character (e.g.,
## @nospell{@qcode{"E&xit"}})
##
## @item @qcode{"position"}
## An scalar value containing the relative menu position.  The entry with the
## lowest value is at the first position starting from left or top.
##
## @item @qcode{"separator"}
## Can be set @qcode{"on"} or @qcode{"off"}.  If enabled it draws a separator
## line above the current position.  It is ignored for top level entries.
##
## @end table
##
## Examples:
##
## @example
## @group
## f = uimenu ("label", "&File", "accelerator", "f");
## e = uimenu ("label", "&Edit", "accelerator", "e");
## uimenu (f, "label", "Close", "accelerator", "q", ...
##            "callback", "close (gcf)");
## uimenu (e, "label", "Toggle &Grid", "accelerator", "g", ...
##            "callback", "grid (gca)");
## @end group
## @end example
## @seealso{figure}
## @end deftypefn
