Hi all,
I'm having a problem with Gtk# 1.9.2 and gecko-sharp 0.6. Using the
two together produces a compile error:
"Cannot convert from 'Gecko.WebControl' to 'Gtk.Widget'"
when I try to add the WebControl to a VBox.
The simplest example of this is compiling the given demo cs file in
the Mono documentation for the WebControl object (also attached). This
demo compiles and works fine when you compile with gtk# 1.x but fails
if you try to compile against gtk# 2 (i.e. with -pkg:gtk-sharp-2.0):
$ mcs GeckoTest.cs -pkg:gtk-sharp-2.0 -pkg:gecko-sharp
GeckoTest.cs(65) error CS1502: The best overloaded match for method
'void Gtk.VBox.PackStart (Gtk.Widget, bool, bool, uint)' has some
invalid arguments
GeckoTest.cs(65) error CS1503: Argument 0: Cannot convert from
'Gecko.WebControl' to 'Gtk.Widget'
GeckoTest.cs(65) error CS1501: No overload for method `PackStart'
takes `4' arguments
Compilation failed: 3 error(s), 0 warnings
$ mcs --version
Mono C# compiler version 1.1.6.0
This is with:
Mono 1.1.6, gtk# 1.0.8 and 1.9.2 installed side-by-side
Mono installed via Gentoo ebuild and gtk from source. This worked fine
with Mono 1.0.6, so this may be a mono problem (maybe the compiler is
more picky?), but gtk# version seems to be the cause of the problem.
Any help would be much appreciated.
Regards,
Mike.
