Dear all, How do I set first column as boolean (shown as checkbox) if I prepare my data with wxgridtablebase? grid.set_col_format_bool does not work Regards Hendra -- Suka linux?

Hi Hendra hendra kusuma wrote:> How do I set first column as boolean (shown as checkbox) > if I prepare my data with wxgridtablebase? > grid.set_col_format_bool does not workTo use custom (eg boolean) renderers and editors with GridTableBase, you need to 1) Call Wx::Grid.register_data_type to associate a named ''type'' of cell with a particular class of cell, eg my_grid.register_data_type(''CheckBoxCell'', Wx::GridCellBooleanRenderer, Wx::GridCellBooleanEditor) 2) Provide a get_type_name method for your GridTableBase class that returns what named ''type'' to use for any given cell. This is demonstrated in the gridtablebase.rb sample, where STRING and NUMBER types are defined alex
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

First column is to display checkbox, > while next column display dataYour subclass of GridTableBase should provide a get_type_name method, which accepts (x,y) parameters and returns a string which corresponds to a named type defined by your Wx::Grid class. Eg, for your example: def get_type_name(x, y) if x == 0 ''CHECKBOX'' else ''STRING'' end end As I say, this is shown in the sample, so have a look there for ''register_data_type'' and ''get_type_name'' best alex
