How to delete content of table data from gui ?

2 views (last 30 days)
I have in my GUI a table wich gather data from multiple edit text trough a button boxes:
global p;
val1 = get(handles.edit2, 'String');
val2 = get(handles.edit4, 'String');
val3 = get(handles.edit5, 'String');
val4 = get(handles.edit6, 'String');
val5 = get(handles.edit7, 'String');
val6 = get(handles.edit8, 'String');
val7 = get(handles.edit9, 'String');
val8 = get(handles.edit10, 'String');
val9 = get(handles.edit11, 'String');
val10 = get(handles.edit12, 'String');
val11 = get(handles.edit13, 'String');
val12 = get(handles.edit14, 'String');
val13 = get(handles.edit29, 'String');
valp1 = get(handles.edit16, 'String');
valp2 = get(handles.edit17, 'String');
valp3 = get(handles.edit18, 'String');
valp4 = get(handles.edit19, 'String');
valp5 = get(handles.edit20, 'String');
valp6 = get(handles.edit21, 'String');
valp7 = get(handles.edit22, 'String');
valp8 = get(handles.edit23, 'String');
valp9 = get(handles.edit24, 'String');
valp10 = get(handles.edit25, 'String');
valp11 = get(handles.edit26, 'String');
valp12 = get(handles.edit27, 'String');
valp13 = get(handles.edit30, 'String');
p.MyData = [p.MyData ; [{val1} {val2} {val3} {val4} {val5} {val6} {val7} {val8} {val9} {val10} {val11} {val12} {val13}...
{valp1} {valp2} {valp3} {valp4} {valp5} {valp6} {valp7} {valp8} {valp9} {valp10} {valp11} {valp12} {valp13}]];
set(handles.uitable1, 'Data', p.MyData);
All I want is to create a button for deleting entire content of the table like this:
tableData = get(handles.uitable1,'Data');
charLocations = cellfun(@ischar, tableData);
tableData(charLocations) = {''};
tableData(~charLocations) = {[]};
set(handles.uitable1, 'Data', tableData);
The problem is after the table data's are delete it and I press the button for gather new data from forms, all the old information come back in the table including the new one. Supose that some how must to clear some buffer or something...

The second problem is when I load a csv with old data into the same table, it loading well ,but when I want to gather new data in order to fill the loaded table it start a new one
code for loading csv
[filename, pathname]=uigetfile({'*.csv'}, 'Select File');
if isequal(filename,0)
return
else
Path=strcat(pathname,filename);
data=readtable(Path, 'Delimiter',',');
data = table2cell(data);
set(handles.uitable1, 'Data', data);
end
guidata(hObject, handles);

All the data returns because you likely have not cleared your variable p.MyData. You code for collecting values appends the new values to the bottom of p.MyData. To get the behavior you want, when you clear your uitable, you also need to delete values in p.MyData.
Perhaps something like p.MyData = [];
