I'm updating a treeview (showing a list of functions, etc. in the current
document), after text has been inserted or deleted from a Scintilla control
with a custom lexer. The treeview is updated based on the text inserted, its
style data, and information on where the insert/delete takes place and the
number of lines added/removed.
Handling SC_MOD_INSERTTEXT and SC_MOD_DELETETEXT in the SCN_MODIFIED
notification would be perfect except that the style data has not been updated
at this point (SCN_STYLENEEDED is sent later) and it is not permitted to
perform the styling in SCN_MODIFIED. At the moment i am styling it in a
separate buffer when SC_MOD_INSERTTEXT/SC_MOD_DELETETEXT is received and then
performing the update. However, this wastes time and memory because the text
has to be styled later in SCN_STYLENEEDED so i wish to avoid this double
styling.
I am thinking perhaps i should create a queue of the relevant
SC_MOD_INSERTTEXT/SC_MOD_DELETETEXT information and process it in
SCN_STYLENEEDED after styling has taken place. Or is it guaranteed there is a
1-1 relationship between SC_MOD_INSERTTEXT/SC_MOD_DELETETEXT and
SCN_STYLENEEDED, i.e. for each insert/delete there will be one and only one
SCN_STYLENEEDED (sent before any more insert/delete notifications) so i can
abandon the queue and handle the one latest insert/delete in SCN_STYLENEEDED?
Or is there (hopefully!) a simpler method?
Have you tried working with the CVS version of Scintilla? Neil
relaxed some of the restrictions on updating in modify event handlers
*after* 1.72 was released (you don't mention what version you are
using, which will usually make it harder for anyone to help you).
