This is crazy. I have a data browser up and running. I can add
items etc. But
for some reason when I click on a row, it won't hilite it. In the
debugger I
see I am getting the appropriate calls to my callback routines.
ie, when i
click on a row, i get the kDataBrowserItemSelected message sent to my
ItemNotification callback. Its as if the screen isn't refreshing
or some crazy
thing.
I have the following code in my callback
case kDataBrowserItemSelected:
status = SetDataBrowserSelectedItems (browser, 1,&itemID,
kDataBrowserItemsAdd);
status =
UpdateDataBrowserItems(browser,kDataBrowserNoItem,
1,&itemID,kDataBrowserItemNoProperty,kDataBrowserNoItem);
InvalidateControl(browser);
break;
I have been going nuts with this. Does anyone have any clues (or
sample code)
that will clear this up for me?
btw - I have looked at the code sample called "basic databrowser".
I don't see
what I am doing differently. Bummer.
I haven't worked with my DB code in a long time, but as far as I can
tell I don't do anything in response to this message and DB seems to
handle everything for me. What happens if you comment out the above
lines of code and do nothing in response?
BTW, the xcode-dev list is for questions related to the use of Xcode
and other Apple development tools, not for Carbon coding questions.
Questions like this should go to the carbon-dev list.
