I just sent this message a few days ago but didn't receive any responses. If there are any DataBrowser experts out there - please, help shed some (any) light on the issue! I'm about to give up on the bug and defer it - I pray my manager doesn't give me hell =)
Here's the original message...
Hi, I have a DataBrowser with container items (like a tree view). There
are times I want to prevent a closed container item from opening and
times when I want to prevent an open container item from closing.
To
do so, I have an item-data callback function (see
DataBrowserItemDataProcPtr). I am correctly handling the first case:
preventing a closed item from opening...
In the callback I check for the propertyID: kDataBrowserContainerIsOpenableProperty Then, to specify if the item can be opened, I call ::SetDataBrowserItemDataBoolean
Value (itemDataRef, canOpen);
The problem is with the other case. There is the following analogous property
kDataBrowserContainerIsClosableProperty But
I never receive a callback requesting that property when the user hits
the close arrow. Has anyone else seen this behavior? As an alternative, is there a way
to explicitly set whether or not a particular item is closable without
being in an item callback function (which provides 'itemDataRef' for
me)?
Thanks in advance for the help!
