Since LibFSAC requires a reified window before loading a font, it
makes sense to have a safe null state for the app.
This lets us stay alive after a failed file request on startup,
handle failure at any point during initialization, and claw back
memory from all our font RefPtrs.
A default startup font or none at all can now be set in FontEditor.ini
Pithier and it matches the naming convention used in FontEditor's
child widgets. Since it was never used outside MainWidget and there
will soon be no guarantee that m_font is nonnull, the public
BitmapFont& getter has also been removed.
As these were only used internally, let's simplify things and prevent
potential desync between widget state and saved settings by moving the
logic into their respective actions.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
Like other apps, FontEditor now organizes widget visibility toggles
under a View->Layout submenu. The main toolbar and the status bar
can now be turned on and off.
This patch will switch cursor to DragCopy when a user enters a widget
while dragging file(s), giving them a visual clue that it *might* be
dropped into this widget.
This is a rather naive approach, as the cursor icon will change for any
kind of file, as currently programs don't know the drag contents before
dropping it. But after all I think it's better than nothing. :^)
Adds fallible functions for opening and saving fonts and cutting
and copying selections. FontEditor now falls back on a guaranteed
default BitmapFont on startup. Fixes crashing on start when the
default system font is set to TrueType.
