Can't inherit from System.Windows.Forms.Form

[Роман Донченко]

Hello,

I'm trying to compile this simple Java class:

~
import cli.System.Windows.Forms.Application;
import cli.System.Windows.Forms.Form;

public class TestForm extends Form
{
     public static void main(String[] args)
     {
         Application.Run(new TestForm());
     }
}
~

I've created stub jars for .NET assemblies:

> ikvmstub mscorlib
> ikvmstub System
> ikvmstub System.Windows.Forms

And when I try to compile the class, this happens:

> javac -classpath mscorlib.jar;System.jar;System.Windows.Forms.jar  
> TestForm.java
TestForm.java:4: get_Container() in cli.System.ComponentModel.Component  
cannot implement get_Container() in  
cli.System.Windows.Forms.Layout.IArrangedElement; attempting to use  
incompatible return type
found   : cli.System.ComponentModel.IContainer
required: cli.System.Windows.Forms.Layout.IArrangedElement
public class TestForm extends Form
        ^
1 error

Well, the meaning of the error is quite transparent:  
System.Windows.Forms.Control, which System.Windows.Forms.Form inherits,  
inherits the Container property from System.ComponentModel.Component, and  
also implements a property with the same name but different type from  
System.Windows.Forms.Layout.IArrangedElement - and in Java, that's not  
possible.

The question is: can I do something about it? I can't find any mention of  
this issue, so maybe it's my fault. The old samples distribution suggests  
that extending Form is possible, albeit it seems to predate .NET Framework  
2.

I'm using Windows, JDK 1.6.0_16, and here's the output of ikvm -version:

Hi,

I have run you program with the current HEAD branch without any error messages and I see a gray window. Can you test the
0.42rc http://weblog.ikvm.net/? It look like that Jeroen has fix this problem.

[Jeroen Frijters]

Hello Roman,

You're not doing anything wrong. This probably got broken at some point, either by a change to .NET or by a change to ikvmstub.

I will add a fix (really a workaround) for this to IKVM 0.44 (not 0.42, which is the next release). In the mean time, if you want to continue, I've created a fixed System.Windows.Forms.jar that is available here:

http://www.frijters.net/System.Windows.Forms.jar

I've created this by fixing my development version to ignore non-public interfaces. I will check in a variation of this fix soon.

BTW, another (more cumbersome) alternative would be to decompile the jar and then fix it. Or even write the stubs by hand. As long as the parts that are used match with what ikvmc sees in the assembly (when you reference the assembly with -r, don't include the stubs in that case) it will substitute the real types.

Regards,
Jeroen

Hi Volker,

What Java compiler did you use? With javac from JDK 1.6 the problem does show up, but I suspect that not all Java compilers (or versions of javac) behave the same.

Jeroen

I have copy the code sample to eclipse. That I think it is the build in compiler of eclipse. I have not expected such
difference.

I just tried it with the Eclipse Java Compiler (from the command line) and it does indeed compile with the "broken" jar. So that is another workaround.
