André,
if I have a math inset that contains sub-insets (fractions, macros etc) then
leaving any one of these sub-insets causes a new preview to be generated. I
believe that the solution is to check that we're leaving the InsetFormula
itself and that the appropriate fix is:
void MathNestInset::notifyCursorLeaves()
{
- //lyxerr << "leaving " << *this << "\n";
- if (!mathcursor || !grfx::Previews::activated())
+ if (!mathcursor || !grfx::Previews::activated() ||
+ mathcursor->depth() != 1)
return;
InsetFormulaBase * inset = mathcursor->formula();
BufferView * bufferview = inset->view();
if (!bufferview || !bufferview->buffer())
return;
grfx::Previews & previews = grfx::Previews::get();
grfx::PreviewLoader & loader = previews.loader(bufferview->buffer());
inset->generatePreview(loader);
loader.startLoading();
}
It seems to work, but Is It Right?
Angus
ps. Hope the talk went well.
