Generate a Matrix of Selectable checkboxes

All, 
   Wondering what is the easiest way to generate a matrix of selectable checkboxes . So what i would like to be able to do is - generate a non- square matrix and pop it up for the user to select any position in the matrix the user would like. As long as the user can select multiple rows within a column and vice versa - it would be good to meet the need. Any help is appreciated. 

 

 

Re: Generate a Matrix of Selectable checkboxes

I realize I'm late to the game, and hopefully you've already figured this out.  The main issue is you never displayed the Table Box in your code.  I believe the next issue is you analyze the table right after creating it.  I imagine you want to do this after the user has a chance to check the boxes.  Hopefully the below code is closer to what you are looking for.

 

Names Default To Here( 1 );

InputsLoadBasic = Expr(
 LB1 = Lineup Box( N Col( 2 ) );
 LB1 << Append(
  Panel Box( "Test",
   V List Box( V List Box( Text Box( "Arg1" ), NEB_arg1 = Number Edit Box( 2 ), Text Box( "Arg2" ), NEB_arg2 = Number Edit Box( 3 ), ) )
  )
 );
 
 LB1 << Append(
  Panel Box( "Selectable Matrix Test",
   V List Box(
    Button Box( "Enter Target Matrix",
     nR = 12;
     nC = 24;
     SCB1 = String Col Box( "", {} ); 
     
     if(!isempty(TB1),
      TB1 << Delete Box;
     );
     
     For( i = 1, i <= nR, i++,
      SCB1 << Add Element( Char( i ) )
     );
     TB1 = Table Box( SCB1 ); 

     For( i = 1, i <= nC, i++,
      Insert Into( TB1, Check Box( Repeat( {" "}, nR ), <<SET heading=""></SET>

Re: Generate a Matrix of Selectable checkboxes

@Justin_Chilton / @txnelson / @thomasz
     I have a follow up question, wondering if any of you could think of a way to do this. I am trying to generate the matrix of selectable boxes within a Panel Box. Here is the script, I have, wondering if you could guide as to why I am failing ? 

InputsLoadBasic =
Expr(
  LB1 = Lineup Box( N Col( 2 ) );
  LB1 << Append(Panel Box( "Test",
         V List Box(
           V List Box(
              Text Box( "Arg1" ),
              NEB_arg1 = Number Edit Box( 2 ),
              Text Box( "Arg2" ),
              NEB_arg2 = Number Edit Box( 3 ),
                )
             )
          )
      );
            
  LB1 << Append(Panel Box( "Selectable Matrix Test",
         V List Box(
            Button Box("Enter Target Matrix",
               nR = 12;
               nC = 24;
               SCB1 = String Col Box( "", {} ); 
                                                      
               For( i = 1, i <= nR, i++,
                SCB1 << Add Element( Char( i ) )
                  );
               TB1 = Table Box( SCB1 ); 
                                                     
               For( i = 1, i <= nC, i++,
                Insert Into( TB1, Check Box( Repeat( {" "}, nR ), <<SET heading=""></SET>

The resulting UI looks like what I want, however, when I click on the  "Enter Target Matrix" button shown above, it does not do what I want. Can you please help 

Re: Generate a Matrix of Selectable checkboxes

You can add a heading to a CheckBox within a TableBox using the <

nRow = 5;
nCol = 6;

// string col box for row labels
scb = String Col Box( "", {} );

// add labels to rows
For( i = 1, i <= nRow, i++,
 scb << Add Element( "row" || Char( i ) )
);

// create a table box to contain everything
tbl = Table Box( scb );

// add all columns with the given number of rows
For( i = 1, i <= nCol, i++,
 Insert Into(
  tbl,
  Check Box(
   Repeat( {" "}, nRow ),
   <<SET heading=""></SET>

Re: Generate a Matrix of Selectable checkboxes

@Justin_Chilton, 
      1 follow up question I have is - Is it possible to add text on top of each column and at the beginning of each row  ?

      If so, what would be an  efficient way to do it ? Should each of them be wrapped in a text box ? 

 

 

Re: Generate a Matrix of Selectable checkboxes

@uday_guntupalli,

You can use a CheckBox() within a Table Box to create a table of check boxes. 

 

nRow = 5;
nCol = 6;

// create a table box to contain everything
tbl = Table Box();

// add all columns with the given number of rows
For( i = 1, i <= nCol, i++,
 Insert Into( tbl, Check Box( Repeat( {" "}, nRow ) ) )
);

New Window( "Check Box Example",
 tbl,
 Button Box( "Show results",
  // initialize the result
  result = {}; 
  // loop through each row
  For( i = 1, i <= nRow, i++,
   // initialize the row list
   result[i] = {};
   // loop through each column getting values
   For( j = 1, j <= nCol, j++,
    result[i][j] = tbl[CheckBoxBox( j )] << get( i )
   );
  );
  // convert the list to a 2-d matrix
  result = Matrix( result );
  Show( result );
 )
);

Here's what the window looks like:

And here's the result in the log with the above selected Check Boxes:

 

result = 
[ 1 0 0 0 0 0, 
 0 1 0 0 0 0, 
 0 0 1 0 0 0, 
 0 0 0 1 0 0, 
 0 0 0 0 1 0];

 

 

Re: Generate a Matrix of Selectable checkboxes

@thomasz, 
       I think for my needs - it looks good. However, if I may - I have a couple of follow up questions:

1. Are the selected positions retrievable ? - If yes- can you kindly provide an example of how to retrieve that data ? 

2. Is it possible to add a little more text around this window ? More like an X - axis label and a Y-Axis label 

Re: Generate a Matrix of Selectable checkboxes

Not a very elegant solution, but something like this may work:

lv={};
for(i=1,i<=4,i++, insert into(lv,""));
tCB="";
for(j=1,j<6,j++,tCB||="check box( (lv)),"); 
tCB=substr(tcB,1,length(tCB)-1);
eval(parse(eval insert("wind=new window( \!"Check boxes\!",
 H List Box(
 ^tCB^))")));
