Hi, Klaas!
We run into a drawing problem with a2dVisibleProperty updated
at runtime and we would appreciate your advice:
1) a2dVisibleProperty is created as follows:
a2dVisibleProperty * pppvis =
new a2dVisibleProperty( this, propid, x, y, true,
new a2dFontDc( font_size, wxTELETYPE, wxNORMAL, wxBOLD ) );
pppvis->ShowName( false );
pppvis->SetNextLineDirection(true);
pppvis->SetFill( a2dTRANSPARENT_FILL );
pppvis->SetStroke(new a2dOneColourStroke(wxColour(_("BLACK")), 0.2));
pppvis->SetMultiLine(true);
pppvis->SetAlignment( wxLEFT|wxBBOX|wxBOTTOM);
2) The properties for objects on the diagram are updated
all at once every second with SetPropertyToObject() call.
3) Everything is working fine (see attached good.png screenshot) but
sometimes
we get white areas over the property (see attached bad.png screenshot).
4) The problem appears or disappears if you slightly change the size,
zoom or
objects layout.
I believe we are missing something really simple (e.g. some call after
all the property updates to force recalculation of something). But we can
not figure it out ourselves.
BTW, the diagrams from new version of wxart2d look MUCH nicer and more
polished. I guess, it is caused by some changes in the anti-aliasing.
Really, really great improvement!
Thanks in advance for your help!
Aleksey
