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.

There are a few different options for viewing help files:
|
|
(1) Microsoft HTML Help. Requires writing stuff in a specific way and then running a
|
|
tool to turn it into a .chm file, which then requires a help viewer application.
|
|
Feels a little weak in terms of future-proofing and cross-platform support.
|
|
(2) Plain HTML, using System.Windows.Forms.WebBrowser class. This seems like a nice
|
|
way to go, but we need to provide all the standard controls, and it means we have
|
|
a web browser running in-process.
|
|
(3) Plain HTML, with the Microsoft.Toolkit.Win32.UI.Controls.WinForms.WebView control.
|
|
Similar to WebBrowser, but newer and fancier, and probably less portable.
|
|
(4) Plain HTML, viewed with the system browser. We outsource the problem. The big
|
|
problem here is that the easy/portable way (Process.Start(url)) discards the anchor
|
|
part (the bit after '#'). There are workarounds, but they seem to involve dredging
|
|
the default browser out of the Registry.
|
|
(5) Custom roll-your-own solution. Have you seen this round thing I invented? I'm
|
|
calling it a "wheel".
|
|
|
|
For now I'm going with #4, and dealing with anchors by ignoring them: the help menu item
|
|
just opens the TOC, and individual UI items don't have help buttons.
|
|
|
|
What we need in terms of API is a way to say, "show the help for XYZ". The rest can be
|
|
encapsulated here.
