Image preview widget overflow to other widgets in FilePicker dialog when image is larger than 160px. Also change the ImagePreview widget variable name for align to naming standards.
And move canonicalized_path() to a static method on LexicalPath.
This is to make it clear that FileSystemPath/canonicalized_path() only
perform *lexical* canonicalization.
Well, technically the initial sort order is 'ascending inode'.
However, that is unpredictable for the user.
In the rare case it is desired, it can be re-enabled by revealing the
inode column, and then sorting by it, in the TableView.
Now that add() returns a WidgetType&, we can't rely on the parent of a
GUI::Dialog to still keep it alive after exec() returns. This happens
because exec() will call remove_from_parent() on itself before
returning.
And so we go back to the old idiom for creating a GUI::Dialog centered
above a specific window. Just call GUI::Dialog::construct(), passing
the "parent" window as the last parameter.
Since the returned object is now owned by the callee object, we can
simply vend a ChildType&. This allows us to use "." instead of "->"
at the call site, which is quite nice. :^)
This is causing FilePicker to log a bunch of debug noise due to the
missing support for tree models in SortingProxyModel and it's not
helping anyone so let's just disable it.
This needs fixing in SortingProxyModel.
