Re: [wxCode-users] wxTreeListCtrl 1104

[asadilan i. <asa...@gm...>]

Hi Ronan,

I did not try it with the sample.
I have an application that uses the tree ctrl, the earlier version.
what it does is build trees, allow double clicking, drag and drop,
automatic scroll (drag the item out of the window/ into the window, the
tree automatically scroll)
and attaches data to every item in the tree.

What i did, i just replace the files( the source and the header ) and run
my app like as usual and thats when i noticed the memory leak.

the scrolling:
lets say i have a small window and really a lot of tree item with child
item and stuffs. i expanded the view (all tree item are expanded), what you
will see is a a lot of tree items that wont fit into the window.when this
happen, a scroll bar will appear.
what i was going to do was when user drag an item up, to the item that can
t be seen, i want the tree to scroll up so that the item above will be
seen. same thing with going down.
What i implemented now is by checking the tree size limit, it will
determnine if the dragging should be up or down.
Once its determined, i just do scrollto the next item.
So far so good, the only flaw happen when user is trying to drag up and
down up and down without releasing the mouse button.
what i found is everytime the cursor enter the window, onbegindrag event
will called.

Please let me know if further information needs to be provided.

If you are not using wxTreeListCtrl, is there an alternative that people
use now or you just dont use it as much as u dont really need it?


Thank you very much Ronan.
