Failed to "dot indexing" the data from uitable
显示 更早的评论
Hi, I am trying to build a GUI with some simple user interactions.
Outside of GUI, I can do "Dot indexing" by referring to its "variablenames". For example, for a table T, I can use "T.Size" to obtain data under the variable name "Size". However, the trick does not work when it involves the GUI.
For "app.UITable", the data is stored under "app.UITable.Data". I tried "app.UITable_OSS1.Data.Size" but it returns an error.
"Dot indexing is not supported for variables of this type."
How could I adjust to make it work? Thanks.

The Data property of a uitable can contain different types of data, as stated on this documentation page. If you had stored a table array that contains a variable named Size in that uitable, I would expect that operation to work. But if you'd stored a non-table array in that uitable, it wouldn't.
A = [1 2 3; 4 5 6]
T = array2table(A, 'VariableNames', ["Size", "Weight", "Temperature"])
T.Size % Works
A.Size % Does not work
So either create / populate the uitable using a table array or modify your indexing based on whether the Data property istabular.
