Hi,
I've got some questions about frames and views.
Firstly... It seems that the main way frames get views is via
nsHTMLContainerFrame::CreateViewForFrame, is that correct? And that's
usually called right after the frame is created, right? (why is that
method on nsHTMLContainerFrame? wouldn't a more generic class be better?)
All correct, as far as I know. (including the parenthetical comments)
When is reflow called in relation to that? At some unspecified time
later (off an event)? If a frame's Init method posts an event, would
that usually fire before or after Reflow has happened?
I'm not really familiar with that, so I can't give a good answer.
Do frames have an easy way of knowing whether they were already reflown
at least once?
NS_FRAME_FIRST_REFLOW flag.
Do views start out hidden or shown?
There's a flag on nsIViewManager::CreateView which defaults to visible.
thanks,

Hope that was helpful.
