Hi,
lots of types in lcltypes are declared as packed,which i dont know why,
as far as i know lots of them are similar to types with almost exact
name from windows unit,but as you look at windows unit,none of them are
packed.
also almost all of these records are by itself 2byte or 4byte
aligned,ie removing packed will not influence them.
The problem is in wince, by using packed lots of things change,compiler
now generates unaligned codes,and becouse it defaults packing to
1byte,packed variables might reside in odd number memory places.
This doesnt make problem in program,becouse all accesses are done in
one byte schema,but when sending these records to winapi,they all
generate errors,which is really hard to find too!
I suggest removing all packed records when they are unessesary.
IMO, the LCL doesn't need packed records. It is only a penalty for
nothing to have them.
If they are used by the win32 interface to send them directly to the
winapi, they have to be copied to proper win32 api formats in the win32
widgetset itself.
So removing things may break some code, but that IMO doen't mean that we
shouldnt change.
