1. whenever I try to run the generated WebKit.exe, it fails on loading

supposed to run the Cairo port, or did I somehow mess up my build?
Obviously, this problem does not exist with WinLauncher.exe or the test
wrapper app I built (which is essentially a clone of WinLauncher).
The FontMetrics call (and the associated WebKitGraphics.cpp
implementation) is used internally by Safari (and perhaps other Apple
products), and are not really part of the "WebKit" API. I elected not
to implement them, as I did not have any specific need. If you have a
compelling use case, we can see about getting them activated for
non-Apple builds.
2. One of my test html pages has a javascript button click event handler
that invokes window.print(). For some reason, this call silently fails when
the page is loaded into WinLauncher. FWIW, I see the same behavior with the
Chromium Embedded Framework. But the windows (non-cairo) WebKit.exe and
Safari do not fail this call. And neither does a build of Chromium. Any
pointers?
By "Fail Silently" you probably mean nothing happens.
To implement printing support, you need to implement the printing
support functions in the IWebUIDelegate class. I implemented enough
of this in the WinLauncher example to use the menu to perform
printing, but I did not implement the "printFrame" method.
If you implement printFrame, then everything should work.

Thanks Brent, Jerry and Alex. Implementing printFrame by copying the
relevant bits from WinLauncher took care of the print issue.
I don't have a particular need for implementing FontMetrics or running
Safari with the Cairo build - so that's not really an issue.
Thanks much,
Sunil
