table in GUI --> data to matrix, expandable array
显示 更早的评论
Hey Guys,
i'm just working on a GUI and until now i just an extra dat-file for the input of my values.. but now i would like to use the table in the GUI!
So my questions are:
How do get the data input from the editable table in the GUI into a matrix i can use in my m-file?
and how can i add more rows to the table (from the UI) and remove unused ones? (would be even better if this could happen automatically..)
Hope you can give me a hand i just can not find a way,...
Thx
Mwafrika

First, create an example table.
h=uitable('data',magic(5),'columneditable',true,'RearrangeableColumns','on');
Then, make any arbitrary changes on the data. If you want to get the new data in your .m file, make sure you have access to the handle h.
data=get(h,'data');
If you want to add or remove rows, you can add a button say "add row" and then in the callback function, do something like this.
data=get(h,'data');
data(end+1,:)=0;
set(h,'data',data');
To remove a row, if you could have a way to specify the row number r, for example r=2, you can do.
data=get(h,'data');
data(2,:)=[];
set(h,'data',data);

Small change: "data" will be a cell array, so you cannot set dat(end+1,:) to the numeric value 0. You can set it to {0} or {} or as appropriate.

I am not sure. When I use h=uitable('data',magic(5)), class(get(h,'data')) is double. So it is the other way around. But, in general, yes, should look at the data class to do things differently.
