Gtk.PrintOperation stopped working on Windows 10
I have a cross platform application that I developed under OXS with Visual Studio that should mainly run under Windows. Lately I realized, that the Gtk.PrintOperation now causes a System.AccessViolationException under Windows, regardless if I build it as native Windows Application using GtkSharp on Windows or run the Mono build from the OSX build by Mono. About one month ago, every thing worked fine.
I am clueless at this point, because nothing I tried worked out. Is there anyone who can still print with Gtk under Windows? Is there a C# application that I can build and try? I did fail to get the gtk-sharp libraries and examples built on Windows. The documentation was to poor to understand what I therefor need.
Any suggestions?
Is this using gtk# 2.12? Might be a problem in the bindings. I'll take a look and release a new version if it's 2.12
Yes it is 2.12.45, as it is in the installer for .net Windows. Thanks allot for your support!
Seeing the dame thing here. It seems that the callbacks are not getting generated with the userdata parameter, have to figure out why.
Huh, no, the class only has these two: https://github.com/bratsche/gtk/blob/ff3424b5ef5177f32fa6933cee439dfa3d3d89b8/gtk/gtkprintoperation.h#L91
I'm wondering if there's some mis-use at gtk level of the native Windows APIs. The bindings look okay.
I'm trying to pin down whether it's a problem with gtk# or some windows update changed something.
As fare as I know, I did not change anything at the libraries and at the usage. Furthermore I checked out the version from a month ago, built it new and it also failed. So I am pretty sure, that it is something within the print layer. I also had the last windows update in mind, but could not tell, because there was no possibility to debug the cause. This was the reason, why I was asking if anyone knows an application that uses Gtk.PrintOperation, so that I can check, whether this application has this issue now too.
Yup, seems to not be gtk# (the bindings) at fault. Maybe something in gtk+, which I don't have expertise in fixing.
Hmm, who could we contact then? Who is the provider of the gtk library? Should Gimp than be affected also?
I now tried Gimp 2.10 under Windows and it is not affected. So at least the new GTK+ libraries (that I guess are included within Gimp) are working fine. Is there anything I can check? What are the affected dependencies of the gtk-sharp package?
You cannot be sure that Gimp is shipping the most recent gtk. Recreate the desired behaviour in a simple c program and check if the error is present on Windows.
Ok, which gtk libraries are used within gtk-sharp? Do you know the repository?

Are there any further steps in progress or do I have to surround it by using the Windows libraries?
