Hi,

I meet some problems and wonder if you could help me out.

Suppose we have two uitable objects, say A and B, both visible all the time. Users could make selections in both A and B. The goals I try to reach are

1, how can I/code check/detect whether uses make selections in both A and B;

2, assuming users make selections in both A and B, users can clear their selections in uitable A using ctrl+click, but how can the code clear the selections in A automatically?

I have googled online for quite a while, but I have no luck out of it. could anyone nicely help me out? Thank you.

Jon

在 MATLAB Online 中打开

If you want to clear all the selections, you can redraw the table (h is the uitable handle):

tmp = get(h,'data');
set(h,'Data',[]);
set(h,'data',tmp);
clear tmp

I think I sort of figure out how to do the first one in the old way:

set global flags in corresponding _CellSelectionCallback function for both A and B, we can simply check the flags to see if selections are made.

I still don't know how to clear selections user makes by the code....

Thank you Teja and it works. My own tries did not have "set(h,'Data',[]);" step and that's why I failed to clear selections. Simple but useful trick. :-)
