Hi,
I''ve yet another issue with my favourite toolkit.
When I''m adding a TreeCtrl that has the TR_MULTIPLE style set, the
event
"evt_tree_sel_changed" most oftenly gets fired multiple times (whereas
a
TreeCtrl with single selection only fires once - as expected). The
exception is the automatic root-selection at program startup and when
I''m widening or narrowing the selected nodes holding ctrl and using the
cursor keys.
See the attachment or below for an example how to reproduce this.
I''m working on WinXP, wxRuby 2.0.0, ruby 1.8.6
require ''wx''
include Wx
class MyFrame < Frame
def initialize
super nil, -1, "Tree: select-event error?"
@tree = TreeCtrl.new(self, -1, :style => TR_MULTIPLE)
@root = @tree.add_root ''root'', 0
[''one'', ''two'',
''three'', ''four''].each do |i| add i end
@tree.expand @root
@num_sels = 0
evt_tree_sel_changed(@tree) do |e|
@num_sels += 1
puts "sel event #{@num_sels}"
end
end
def add item
node = @tree.insert_item @root, 0, item, 1
child = @tree.insert_item node, 0, "child", 2
@tree.insert_item child, 0, "grand-child", 2
@tree.expand node
@tree.expand child
end
end
class MyApp < App
def on_init
f = MyFrame.new
f.show
end
end
MyApp.new.main_loop
Thanks in advance for any hint,
Christian.
