GridTableBase

Desktop wxRuby
1

Hello all,
i’m using wxruby 1.9.4 with Grid and the model class: “GridTableBase”
like in the code below. But the method set_table of the grid does’nt
work. Can anyone help me?

require ‘wx’
include Wx

class MyGridTableBase < GridTableBase
def get_attr row, col, attr_kind
##
end

def get_number_rows
0
end

def get_number_cols
0
end

def get_col_label_value col
return “empty”
end

def is_empty_cell row, col
return false
end

def get_value row, col
return “empty”
end
end

g = Grid.new
gt = MyGridTableBase.new
g.set_table gt

i get one of this errors:

TypeError: in method ‘SetTable’, argument 2 of type 'wxGridTableBase

*’

or a “unknown software exception” (0xc0000094) on 0x030dc124 is

thrown

Best Regards,
Franz

If this is all top level code, you need to initialize the Wx::App class
first. When I try this, and change the bottom part where you create the
new
grid and gridtablebase, it runs alright.

App.new do
g = Grid.new
gt = MyGridTablebBase.new
g.set_table(gt)
end

What platform are you running on?

Hello,
ok, it was only a code snippet, but normally it should run in a window,
like in the code below:
I’m running Windows XP and i always get the error:
in `set_table’: in method ‘SetTable’, argument 2 of type
‘wxGridTableBase *’ (ObjectPreviouslyDeleted)

require ‘wx’
include Wx

class MyGridTableBase < GridTableBase

def initialize rowObjs, objType
@objType = objType
@rowObjs = rowObjs
@colNames = [“aa”, “bb”]
end

def get_attr row, col, attr_kind
# todo
“”
end

def get_number_rows
return @rowObjs.size
end

def get_number_cols
return @colNames.size
end

def get_col_label_value col
return @colNames[col]
end

def is_empty_cell row, col
return false
end

def get_value row, col
@rowObjs[col]
end

def set_value row, col, value
end

end

class TestWin < Frame
def initialize *args
super(*args)
StaticText.new self, -1, “Test Test Test”
@g = Grid.new self
@gt = MyGridTableBase.new [“aa”, “bb”], String
@g.set_table(@gt) ## !!!

end

end

class TestApp < Wx::App
def on_init
frame = TestWin.new(nil, -1, “Grid Sample”,Wx::Point.new(10,
100),Wx::Size.new(630,400))
set_top_window(frame)
frame.show()
end
end

TestApp.new.main_loop()

App.new do

end

Best regards,
Franz

A lot of thanks,

I thought because GridTableBase is a interface, … but we are in Ruby,
and here a interface is a class!

You need to call super() in your constructor. Sorry the (SWIG-generated)
exception isn’t very informative, but it’s trying to say that the
underlying C++ object hasn’t been initialised.
