194905 - XUL needs overflow handling

Status: NEW

(Core :: XUL, defect)

Description

dialog/window/page elements in XUL need some possibility to handle overflow.

Especially on Dialogs, we'd need a possibility to auto-shrink/grow the whole
dialog based on the XUL content. In localized versions, with different themes
(or nsITheme) or even different font size settings (e.g. "big fonts" on
windows), we often see issues that buttons of dialogs get cut off or text gets
cut off at the right or bottom of the dialog. This should not happen, we should
just grow the dialog to fit that.

on page, e.g. pref dialog, we sometimes get some details cut off, where a
scrollbar to handle that overflow would at least guarantee access to overflowing
elements.

So what I think we need is some "overflow:" CSS property with values like
"auto", "scroll", "hidden", like CSS already has, but we should also add some
"fit" value, which should also follow max/min-height/width properties.

This would also help a bunch of themes and L10n problems...

You mean like not setting the size on the dialog, which does exactly that?
