[wxruby-users] column as boolean with wxgridtablebase

[hendra kusuma]

Thanks Alex. I still cannot get that working
I dont get what you mean on point 2

here is my case
I want to display data from database, I give resultset as parameter to
create this gridtablebase object. First column is to display checkbox, while
next column display data

my class is about like this

class Ds_anggota_grup < Wx::GridTableBase
  attr_reader :cols, :rows
  def initialize(rs)
    super()
    @data = []

    @col_names = ["", "Grup", "Id"]

    begin
        rs.each do |row|
            each_row = []
            each_row << 0
            each_row << row[:grup]
            each_row << row[:id]
            @data << each_row
        end
        @rows = @data.size
        @cols = (@data[0]).size
    rescue
        @rows = 0
        @cols = 0
    end
  end

  def get_number_rows
    @rows
  end

  def get_number_cols
    @cols
  end

  def get_value(row, col)
    (@data[row])[col].to_s
  end

  def get_attr(row, col, attr_kind)
    Wx::GridCellAttr.new
  end

  def is_empty_cell(row, col)
    true
  end

  def get_col_label_value(col)
        @col_names[col]
    rescue
        ""
  end

  def set_value(row, col, val)
    #puts "Changing the value of cell (#{col}, #{row}) to '#{val}'"
  end

end


I assume you told me to add def get_value_as_bool(row, col)
but I dont get what should I add there
and if I add empty def it only give error

What is to add there?

Regards
Hendra
