TreeCtrl#get_item_data
Hi
I saw from the ChangeLog that [get|set]_client_data was removed from
ComboBox for 0.4.0 because the methods weren''t working properly.
TreeCtrl#get_item_data still seems to be there. I was wondering if
someone who understood the issue could say if TreeItemData might also be
afflicted with the same problems?
I seem to be segfaulting quite a bit (actually, on TreeEvt#get_item),
but it disappears when I don''t use item_data. The methods are easy

TreeCtrl item_data
The attached fixes set_item_data, get_item_data and some other methods
for the TreeCtrl so they work nicely with Ruby objects and GC.
In C++ Wx TreeCtrl item_data works differently from client_data in
classes derived from ControlWithItems (eg Choice, ListCtrl). A
one-to-one mapping of the way TreeCtrl works would mean that you would
have to...

listctrl set_item_data
Hi,
I have used set_item_data with ruby objects (an array) and got a crash.
The reason is simple, the objects were deallocated by the GC.
The easy solution would be to accept only long parameters (like the
original interface).
The hard is to play by the GC''s rules and increase the reference count
and decrease on deletion.
Regards,

Bug? in wxSugar enumerable_controls.rb
...wx_classes/enumerable_controls.rb'' as following :
def each(&block)
last = get_count - 1
case block.arity
when 1
0.upto(last) { | i | yield i }
when 2

when 3
0.upto(last) { | i | yield i, get_string(i), get_item_data(i) }
else
raise ArgumentError, "Invalid number of block parameters"
end
end
This method works well if used directly.
The problem is that methods from Enumerable like find_all, collect ...

some wxruby questions
...his true? and
if not, is there a work around? MODERN fonts are NOT fixed width,
especially on debian
3) Are there some memory problems with tree control? I instantiate a
tree control, add some items and then if I call this code several
minutes later, I often get a seg fault :
get_item_data(get_selection).absolute_filename
(where absolute_filename is a method on the item data)
this works, for a while and then it starts seg faulting. I''m guessing
that somewhere the ruby garbage collection is prematurely collecting
these items? has anyone else seen this. It''s re...

[ wxruby-Bugs-13640 ] Invalid value for TreeCtrl#get_root_id when TR_HIDE_ROOT style is set (MSW)
...ed to: Alex Fenton (brokentoy)
Summary: Invalid value for TreeCtrl#get_root_id when TR_HIDE_ROOT style is set (MSW)
Initial Comment:
When a TreeCtrl is created with the TR_HIDE_ROOT style, the id values returned by add_root and get_root_id are invalid (-65636) - if passed back into get_item_text , get_item_data, item_has_children etc nothing is returned.

GenericDirCtrl#re_create_tree behaviour
Hi
When GenericDirCtrl#re_create_tree is called in order to refresh the
tree with any possible changes made to the file system since it was
loaded, it doesn''t re-expand all the tree items that were expanded
prior to calling re_create_tree. I''m working on a solution to note all
open tree items and after re_create_tree manually expand the items
that are still present in the tree.

Hi,
I''m pretty new to WxRuby, but I think it is the ideal solution to write
Ruby-applications for different platforms. I missed the wxHtmlWindow in
WxRuby, so I added it myself. You can grab the new files from

files I added to the wxruby-directory. These are mostly the *.t files

Crash when using item data with a CheckListBox
...ot;five"]

When an item is selected, the corresponding data is ouput.
If the list box is replaced by a check list box, the application
crashes immediately.
Cheers.
