Retrieve application-defined data
Use this function to retrieve data stored using the
setappdata function. Both of these functions provide a convenient way to
share data between callbacks or between separate UIs.
val = getappdata(obj,name)
vals = getappdata(obj)
Create a figure window.
f = figure;
Get the current date and time as separate variables.
dt = fix(clock); currdate = dt(1:3); currtime = dt(4:6);
Retrieve the date information.
ans = 2014 12 23
Retrieve all data associated with figure
ans = todaysdate: [2014 12 23] presenttime: [16 51 5]
obj— Graphics object containing the value
Graphics object containing the value, specified as any graphics object
(except an ActiveX® component). This is the same graphics object passed to
setappdata during the storage operation.
name— Name identifier
Name identifier, specified as a character vector. This is the same name
identifier passed to
setappdata during the storage
val— Stored value
Stored value, returned as the same value and data type that was originally stored.
vals— All values stored in the graphics object with name identifiers
All values stored in the graphics object with name identifiers, returned as a structure. Each field in the structure corresponds to a stored value. The field names of the structure correspond to the name identifiers assigned when each value was stored.
