In particular, having a living VCL window as child of the document window, and coupling this Window to a drawing layer object, makes things difficult sometimes. Below is a list of issues which existed in the past. Whenever you change code here, you're encouraged to verify those issues are still fixed. (Whenever you have some additional time, you're encouraged to write an automatic test for one or more of those issues for which this is possible :) https://bz.apache.org/ooo/show_bug.cgi?id=105992 zooming documents containing (alive) form controls improperly positions the controls https://bz.apache.org/ooo/show_bug.cgi?id=104362 crash when copy a control https://bz.apache.org/ooo/show_bug.cgi?id=104544 Gridcontrol duplicated after design view on/off https://bz.apache.org/ooo/show_bug.cgi?id=102089 print preview shows control elements with property printable=false https://bz.apache.org/ooo/show_bug.cgi?id=102090 problem with setVisible on TextControl https://bz.apache.org/ooo/show_bug.cgi?id=103138 loop when insert a control in draw https://bz.apache.org/ooo/show_bug.cgi?id=101398 initially-displaying a document with many controls is very slow https://bz.apache.org/ooo/show_bug.cgi?id=72429 repaint error in form wizard in bugdoc database https://bz.apache.org/ooo/show_bug.cgi?id=72694 form control artifacts when scrolling a text fast */ namespace sdr { namespace contact { using namespace ::com::sun::star::awt::InvalidateStyle;
