While I was at it, I noticed that the ASCII chart and hex dump
viewer windows were always in front of the main app window. It looks
like child windows are always in front. The easy fix is to not
set an owner.
This causes a new problem: the windows don't get closed automatically
when the parent window closes, and the app won't exit until all
windows are closed. So we now explicitly close the hex dump and
ASCII chart windows when the main window is closed, and we now keep
track of all the external-file hex dump windows. (It always sort of
bothered me that we were creating hex dump windows and not keeping
track of them. Itch has now been scratched.)
Also, changed the ascch-mode setting to be an enum rather than an
integer. Renamed the setting to ascch-mode1.
The contents of cdlv-col-widths and hexd-char-conv have changed. The
app correctly ignores things it doesn't understand when going either
forward or backward (between SourceGen and SourceGenWPF), but it's
nicer to just not have the settings get clobbered.
Notable items include the column show/hide buttons, which were
straightforward except for the "determine the default width" part,
and the font picker, which is no longer a standard dialog. The
latter was complicated by the absence of a good way to detect
whether a font is mono-spaced or not without calling back into code
meant for WinForms font manipulation (with a dash of PInvoke).
Yay WPF.
Also, enabled character ellipsis for code list items.
This change pulls in the settings file code, which is mostly
unchanged except when it comes to saving and restoring the window
location and size.
The old system has been replaced with a PInvoke-based version that
calls the underlying Win32 window placement code. This is more
likely to be correct when multiple displays are in use, and can
record the un-maximized size of a maximized window. It leaves a
nasty XML string embedded in the config file, but it's not really
meant to be human-readable anyway.
The sub-window dividers all work completely differently from the way
they did in WinForms, and some of the behavior is a bit obscure
(like noticing when a splitter moves due to keyboard input, and
setting the position in a way that doesn't break the auto-sizing).
Yay WPF.
Still need to preserve column widths.
Mostly a straight copy & paste of the files. The only significant
change was to move the localizable strings from Properties/Resources
(RESX) to Res/Strings.xaml (Resource Dictionary). I expect a
number of strings will no longer be needed, since WPF lets you put
more of the UI/UX logic into the design side.
I also renamed the namespace to SourceGenWPF, and put the app icon
into the Res directory so it can be a resource rather than a loose
file. I'm merging the "Setup" directory contents into the main app
since there wasn't a whole lot going on there.
The WPF Color class lacks conversions to/from a 32-bit integer, so
I added those.
None of the stuff is wired up yet.
