"SO I HAVE this ui table i want to select sujects and push 'submit' to calculate the sum of credit for the subject i selected"

In the callback function for the "submit" button, add this section of cose. You'll need to adapt it to your gui. That means you'll need to change the variable names and the column numbers.

% I create a fake UI table just for the example
h.uitable = uitable('Data', [{false;true;true;false;false},num2cell((1:5)')], 'ColumnEdit', [true, true],'ColumnName', {'Select','Credit'});

% In my table, the check boxes are in column 1, then credits are in column 2. 
% * you'll need to adapt this to your table (the variable names and column  numbers)
% * These steps could be combined into 1 line but it's more intuitive this way

% Step 1) Determine which rows have checked boxes
rowChecked = [h.uitable.Data{:,1}]';
% Step 2) Get the credits for each row of checked boxes
credits = [h.uitable.Data{rowChecked,2}]';
% Step 3) add the credits
creditSum = sum(credits); 

"and after that i want to push a clear' button to reset all"

In the callback function to you "clear" button, add this section of code. Again, you'll need to adapt it to your GUI.

% set all checkboxes to false
h.uitable.Data(:,1) = {false}; 
% Remove all credits
h.uitable.Data(:,2) = [];

sorry, Actually i didnt understand you well.

can you help me more.

[Adam Danz]

Do you have specific questions?

[geeks g]

@Adam Danz

i use for exaple

set or get like

set(handles.uitable,'data',false );

this stetment , make me clear all chekboxes????

[Adam Danz]

Close, but not correct.

The set() version would be

data = get(h.uitable,'Data'); 
data(:,1) = {false};
set(h.uitable,'Data',data)

But if you can use the dot notation rather than get(), set(), you should.

i will try

thank you very much

[Adam Danz]

No problem, let me know if you have further questions about this.

I WRITE LIKE YOU TELL ME

NOTHING WORK

AND THERE IS AN ERROE

this my code: after i adapt it to my GUI.

% Step 1) Determine which rows have checked boxes
  rowChecked = [handles.uitable.Data{:,1}];
  rowChecke = [handles.uitable.Data{:,4}];
% Step 2) Get the credits for each row of checked boxes
 credits = [handles.uitable.Data{rowChecked,2}];
  credit = [handles.uitable.Data{rowChecke,6}];
% Step 3) add the credits
     creditSum = sum(credits); 
     creditSu = sum(credit); 
a = creditSum +creditSu ;

[Adam Danz]

What's the complete copy-pasted error message?

[geeks g]

Adam Danz

i put this code in 'submit' button

then i run the program

its ok until now

when i push 'submit'

this error show up

------------------------------

>> Course_Selector_
Reference to non-existent field 'uitable'.

Error in Course_Selector_>pushbutton4_Callback (line 340)

[Adam Danz]

The error message tells you what's wrong:

Reference to non-existent field 'uitable'.

There is no field in "handles" named 'uitable'.

1) Are you writing this in GUIDE or app designer (or something else)?

2) Is this code in the callback function to the submit button?

Please copy-paste the entire call-back function here and please format the code using the format button.

omg omg omg

its work its work

omg it work

but know how could i mov the result of sum AND put it in text?

[Adam Danz]

Ha! Glad to hear it's working! :)

To display the result in your GUI, you need to convert it to a string and assign it to a text object. Let's say your text box is named "textfield".

handles.textfield.String = num2str(creditSum); 
% or, to specify number of decimal places
handles.textfield.String = sprintf('%.1f',creditSum);

[geeks g]

look to this code please

is that ok??

% Step 1) Determine which rows have checked boxes
  rowChecked = [handles.uitable1.Data{:,1}];
  rowChecke = [handles.uitable1.Data{:,4}];
% Step 2) Get the credits for each row of checked boxes
credits = [handles.uitable1.Data{rowChecked,2}];
credit = [handles.uitable1.Data{rowChecke,6}];
% Step 3) add the credits
    creditSum = sum(credits); 
     creditSu = sum(credit); 
a = creditSum + creditSu ;

set(handles.text7,'string',a);

[Adam Danz]

Does it work?

In my examples, I convert 'a' from number to string using one of the two methods below

• num2str(a);
• sprintf('%.1f',a);

yay

yes its work

its stay one step and i finish it

how could i use 'enable' in ui table

if i choose a specialty (IT) in university

i want some subjects to be non enable

[Adam Danz]

Read about the 'enable' property here:

https://www.mathworks.com/help/matlab/ref/matlab.ui.control.table-properties.html#buiu91u-1-Enable

When 'enable' is turned off, the entire table is deactivated. You can't apply this to certain cells. Instead, you could change the selection available whenever a new specialtiy is chosen. For example, whenever IT is chosen the table content could change to a new list.
