Hi everyone.
I've got a funny problem on the T5. When I get a frmUpdateEvent,
I do a FrmDrawForm() and then a bunch of custom drawing on top of
the form. It seems like for whatever reason, when I do the custom
drawing, the clipping rectangle that the system has set is way off,
and some of my stuff doesn't get redrawn when it should. (If I
override the clipping rectangle and then draw, it looks fine.)
For example, let's say I am sitting in my app and a system dialog
(such as a datebook reminder) pops up. The dialog is 160x160
standard pixels, but when I dismiss it, only about half the exposed
stuff in my form gets redrawn. That is, the top 80x160 of the
screen *is* redrawn, but the 80x160 below that isn't. And of course
the bottom third of the screen wasn't ever obscured, so it's fine.
So I end up with a giant white band in the middle the screen!
Anyone seen anything like this? My frmUpdateEvent handler doesn't
do anything really weird -- just looks like this:
case frmUpdateEvent:
FrmDrawForm (_formptr);
Draw ();
handled = true;
break;
The Draw() function is what draws all the custom stuff on top of
the system form.
As far as I know, this only happens on the T5 (and its simulator),
and not on any other devices. The size of the portion of the screen
that's not redrawn seems to be random. Sometimes it's apparently
exactly 80x160, and sometimes it's only what looks like about 60x160.
A similar problem happens if I push the button that changes from
landscape to portrait orientation, but in that case the problem
only occurs if have the graffiti area expanded so that my form
is 160x160 in size. (This makes sense because I never have the
refresh problem when the form size is changed, and obviously
going from tall to wide requires changing the form size.)
