[Mono-winforms-list] Re: [Mono-dev] Getting and injecting Windows Forms messages

[Peter Dennis Bartok]

Pablo,

The better list for this discussion is mono-winforms-list at lists.ximian.com.

If you look at our tests (for example 
mcs/Managed.Windows.Forms/Tests/System.Windows.Forms/Label.cs) you'll see 
that there already are tests that 'fake' messages for testing purposes, 
since our implementation uses Win32 messages even on X11 and OS X. (Our 
window drivers translate native messages into their Win32 equivalents and 
pass them up through the framework). However, we only use and generate the 
subset of messages that we require for proper support of WinForm's 
documented features. (It is left as an excercise for contributors to add 
other messages if they thing the drivers should generate them. Same applies 
to controls, we don't create control-specific notifications like BN_CLICKED 
today, since the managed framework has events that convey the same 
information and we don't need them, but for compatibility it is easy to add 
generation of those down the road. Single line of code most of the time)

There's already an automated test tool called nunit-winforms that allows to 
test winforms apps, it doesn't fully work with our WinForms implementation 
yet (something that's I've started fixing and is on my todo list).

As for injecting messages, I can think of multiple ways of doing that, from 
using reflection to using sendmessage (and on X11 translating that into a 
custom message that our driver understands)

Cheers,
  Peter
