15.4.5 Application-defined Data

Octave has a provision for attaching application-defined data to a graphics handle. The data can be anything which is meaningful to the application, and will be completely ignored by Octave.

setappdata (h, 이름, 값)

setappdata (h, name1, 값1, name2, value3, …)

setappdata (h, {name1, name2, …}, {값1, value2, …})

Set the application data 이름 to 값 for the graphics object with handle h.

h may also be a vector of graphics handles. If the application data with the specified 이름 does not exist, it is created.

Multiple 이름/값 pairs can be specified. Alternatively, a cell array of names and a corresponding cell array of values can be specified.

값 = getappdata (h, 이름)

appdata = getappdata (h)

Return the 값 of the application data 이름 for the graphics object with handle h.

h may also be a vector of graphics handles. If no second argument 이름 is given then getappdata returns a structure, appdata, whose fields correspond to the appdata properties.

rmappdata (h, 이름)

rmappdata (h, name1, name2, …)

Delete the application data 이름 from the graphics object with handle h.

h may also be a vector of graphics handles. Multiple application data names may be supplied to delete several properties at once.

valid = isappdata (h, 이름)

Return true if the named application data, 이름, exists for the graphics object with handle h.

h may also be a vector of graphics handles.
