Re: [xmlvm-users] Releasing of CGBitmapContextRef / CGImageRef

[Arno P. <ar...@pu...>]

not doing a CFRelease in the finalizer of CFType definitely is not OK 
and will leak memory. I looked at the implementation of UIGraphics and I 
don't see anything that would conflict with the finalizer doing the 
CFRelease (i.e., I don't think there is a double-release).

HOWEVER, the finalizer is run by a special finalizer thread (as per Java 
spec). In order to assure that CFRelease happens on the UI thread one 
needs a helper object to do just that. What Paul commented out didn't do 
this and perhaps that was the source of his problem.

I have just committed a patch. Please check if this fixes your problems 
and addresses your concerns.

Re: [xmlvm-users] Releasing of CGBitmapContextRef / CGImageRef

Hi,

I did the implementation of CFType with the release in the finalizer. The idea was, that the GC should take care of CFType-Types, so CFRelease was removed from the Java API. I also build the workaround in the popContext function, since without it  the release would be called one time too much. Maybe the workaround was bogus, but I would definilty choose option 2) so that the GC can handle CFType-Types. I don't know what the current implemenation does, since I'm currently not using any CFType stuff in my xmlvm projects, but if we could get option 2) correctly implemented, that would be great. :)

Re: [xmlvm-users] Releasing of CGBitmapContextRef / CGImageRef

[JR S. <sc...@we...>]

I believe that CFRelease is still needed in CFType.finalize() for 
reasons OTHER than UIGraphics. For example, CGBitmapContext.create() 
generates a CGBitmapConextRef.  Currently there is no corresponding 
".release()" method defined in the Java interface for CGBitmapContext 
(e.g. no way to call CGContextRelease).  A similar issue exists with 
CGColorSpaceRelease. It seems the logic here was that context would be 
released in the finalize method derived from CFType.  But if this is 
commented out, the context is never released -- and there is no 
mechanism to do so.

Assuming I understand your previous post, it would thus seem to me that 
EITHER,
1)  A release method needs to be defined for CGBitmapContext (and other 
similar methods), or
2)  The call to CFRelease in CFType.finalize() needs to be restored, 
which may entail some changes in UIGraphics

The new iOS interface is not an option for me, as it current does not 
appear to implement CGBitmapContext and several other objects.

One fairly simple workaround is to define a Java class with a static 
CFRelease(...) method and implement this in C.  This seems to work for 
me, but its a bit of a hack for something that seems fairly crucial / 
fundamental.

Re: [xmlvm-users] Releasing of CGBitmapContextRef / CGImageRef

[Paul P. <bay...@gm...>]

I believe the reason I commented out the "CFRelease" in CFType.finalize()
is that it was only there in the first place because of a bug in
UIGraphics.  Namely, popContext() was popping the context & then releasing
the current context, which is wrong & a different context altogether.  It
should've been releasing the context that was popped, so I fixed that.

Then, the bug in CFType.finalize() which called CFRelease could be fixed.
I.e. if it was left in there, it'd be incorrectly released twice.  Note
that CGContextRelease is equivalent to CFRelease.

Thanks,
Paul

CGBitmapContext is derived from CFType. The latter overrides finalize(). 
The somewhat funny thing is that the code in 
org_xmlvm_iphone_CFType_finalize_org_xmlvm_iphone_CFType__() is 
commented out. Not sure how that happened.  :)

Yes, via CFType.finalize(), except that the CFRelease() is commented out 
in the C backend (I have no idea why).

It should be handled via the finalizer (in the C backend).

No. The ObjC backend relies on reference counting whereas the C backend 
comes with a proper GC. The two backends can't be mixed.

[xmlvm-users] Releasing of CGBitmapContextRef / CGImageRef

[JR S. <sc...@we...>]

I am curious how CGBitmapContextRefs generated by 
CGBitmapContext.create() are handled, if at all.  A similar issue arises 
with CGImageRef created.

I looked at the C implementation, and from my high-level understanding 
of the code it doesn't appear that there are any finalizers to take care 
of this.  (The DELETE method is empty). Adding to my concern is that the 
objc impemtetion does contain a "release" method that properly calls 
CGContextRelease.

So I am wondering:
1)  Is "CG" resource management being done in the c implementation? If 
so, how?
2)  If no resource management is being done, is there a way to release 
them manually?  I fear that this will require modifying the c 
implementation, which looks extremely difficult.
3)  Alternatively, is it possible to mix-and-match the objective c and c 
implementations of the XMLVM classes?  Writing the objective c 
implementations looks far more straightforward, but I still the c back 
end for full java classlib compatibility.

Thanks in advance for any advice!

Re: [xmlvm-users] Some clarifications about XMLVM and iOS applications

[Markus N. <mar...@gm...>]

Hi Gianluca,

The Java emulator contained in xmlvm is not under active development
anymore and I don"t recommend using it. We instead generate an XCode
project and use XCode and the iOS simulator which comes with it.

I am not familiar with specific differences between iPhone/iPad development
wrt xmlvm. The majority (if not all by now) of the tutorials should run on
the iPad but by default those tutorials will create a project for the
iPhone.
To change that edit xmlvm.properties in the root of each tutorial and
change "xmlvm.project=iphone" to "xmlvm.project=ipad". Then just run "ant
run-Xcode" (e.g. in $XMLVM/tutorial/helloworld/portrait) and XCode should
start automatically after the project gets created. Just press Run now and
you shold be good to go.

[xmlvm-users] Some clarifications about XMLVM and iOS applications

[<puz...@al...>]

Hi All,

I'm new of this list. I downloaded, installed and configured XMLVM in according with the on-line documentation, tried some demo apps, but I have some questions about the XMLVM tool itself:

1) I see that the tool contains an emulator for iPhone. What about iPad's one? Is there a possibility to show up an iPad emulator or emulate in some way its screen behaviour inside XMLVM? Moreover, what changes we have between iPhone and iPad development with XMLVM? I am mainly interested in iPad application development.
2) I tried the TabBar demo app in the tutorial section, but it doesn't work. With any change I made on the code, it doesn't show up the TabBar at all, only the default black screen (or white if I change the background color by Java code).

Re: [xmlvm-users] New to this process

[Markus N. <mar...@gm...>]

Hi Ryan,

.class files are handled with the --in as you have already figured out. To
add additional resources xmlvm uses the --resource parameter.
If you're using eclipse the app will be compiled as .class files to
yourproject/bin/classes by default. Eclipse just won't show them.

For a typical Android project the complete call could look something like
this:
java -jar xmlvm.jar --in=yourproject/bin/classes --out=out
--target=iphonecandroid --app-name=YourProject
--resource=yourproject/AndroidManifest.xml --resource=yourproject/res

@Ryan: Sorry for the spam. Didn't reply all at first

Cheers,
Markus

[xmlvm-users] New to this process

[Ryan D. <ry...@ho...>]

I'm sorry if this question seems trivial, I hope that it is.

I am an android application developer, and am looking into using xmlvm to
cross-compile a few very simple android apps to the i-phone (most the work
is handled on the server-side, so this is basically just a ui with some
POST stuff going on)

I've successfully set up xmlvm, xcode, the android sdk, and the like on a
mac running snow leopard. My question is this: from my understanding of the
documentation, xmlvm looks for .exe, .class and .xmlvm files from the input
parameter. Since my app utilizes androids xml layouts, and certain
important pieces of information is stored in xml files (and packaged art
files) - how do I go about compiling the android app to be comprised of
class files? Developing in Eclipse allows for exporting to apk files, but
i'm not seeing another way to package these as class files appropriately.

Thank you for your time.

Re: [xmlvm-users] Define the layerClass on UIView

[Arno P. <ar...@pu...>]

well, short answer: we don't support that scenario yet.

What you could do: you can inject code on class level using advisor.xml. 
You can use that to inject an Objective-C category that adds a new 
method to the generated wrapper class. A bit of a kludge, but might 
solve your problem for now.

Re: [xmlvm-users] Define the layerClass on UIView

[Spoorthi D'S. <spo...@ma...>]

Hi Michael,

If I understand your problem right, you can achieve what you intend to, by creating a category for UIViewWrapper within org_xmlvm_ios_UIView.m and add the method that you intend to. I think following the example of UIViewControllerWrapper within Advisor to inject the code for the same.

Hope that helps,
Spoorthi

Re: [xmlvm-users] Define the layerClass on UIView

[Mickael B. <mba...@gm...>]

Hi Arno,

Thanks for your really quick answer ! :)

I've just taken a look at what you suggested. But I don't think this
corresponds to what I'm looking for...
I'll be more specific.

If I did understand correctly what does the Advisor, it will add a new
method inside the UIView java class (let's call it "layerClass") and a
native implementation inside org_xmlvm_ios_UIView.m from the code I'll put
inside advisor.xml. I deduced it from what did the toString() method added
inside NSString in advisor.xml :

<class name="NSString">
        <injected-method name="toString" modifier="public">
            <signature>
                <return type="String"/>
            </signature>
            <code language="c" mode="replace">
                <![CDATA[
	return fromNSString(((org_xmlvm_ios_NSObject*)
me)->fields.org_xmlvm_ios_NSObject.wrappedObj);
]]>
            </code>
        </injected-method>
    </class>

This adds the method inside "NSString.java" :

/*
 * Injected methods
 */
public String toString(){
throw new RuntimeException("Stub");
}

 and "org_xmlvm_ios_NSString.m" :

JAVA_OBJECT org_xmlvm_ios_NSString_toString__(JAVA_OBJECT me)
{
    //XMLVM_BEGIN_WRAPPER[org_xmlvm_ios_NSString_toString__]

                return fromNSString(((org_xmlvm_ios_NSObject*)
me)->fields.org_xmlvm_ios_NSObject.wrappedObj);

    //XMLVM_END_WRAPPER
}


That's great, but not what I'm looking for.
What I want to do is add a class method inside the underlying UIViewWrapper
ObjC class.
>From what I'm understanding of it, UIViewWrapper is a generated ObjC class,
extending UIView, and adding methods for managing delegated methods such as
touch events, etc :

Inside "org_xmlvm_ios_UIView.h" :

@interface UIViewWrapper : UIView

// Append the wrapper method declarations defined in the class Macro
XMLVM_OBJC_OVERRIDE_CLASS_DECLARATIONS_org_xmlvm_ios_UIView

@end

Inside "org_xmlvm_ios_UIView.m" :

@implementation UIViewWrapper

// Append the wrapper methods defined in the class Macro
XMLVM_OBJC_OVERRIDE_CLASS_DEFINITIONS_org_xmlvm_ios_UIView

@end


What I need is to be able to add a class method inside UIViewWrapper, so
that it looks like something like this :

@implementation UIViewWrapper

// Append the wrapper methods defined in the class Macro
XMLVM_OBJC_OVERRIDE_CLASS_DEFINITIONS_org_xmlvm_ios_UIView

+ (Class) layerClass {
    return [CAEAGLLayer class];
}

@end


Having generated this method for the "org_xmlvm_ios_UIView" class won't
solve my problem, since the method needs to be generated on the
UIViewWrapper class.
Maybe is it more clear now... :)

Re: [xmlvm-users] Define the layerClass on UIView

[Arno P. <ar...@pu...>]

checkout trunk/crossmobile, then look for a file called advisor.xml. In 
that file do a grep on "toString". This is an example on how a method 
toString() is injected to class NSString. You should be able to do the 
same for a method called layerClass. Once you have done that, do a "ant 
gen-xmlvm-ios" in crossmobile. This will re-generate the iOS API in 
../xmlvm. For this to work you need to point property sdk.path in 
xmlvm.properties to an installation of the iOS 4.3 SDK (note that 
crossmobile cannot deal with 5.* API yet).

[xmlvm-users] Define the layerClass on UIView

[Mickael B. <mba...@gm...>]

Hi everyone,

I recently switched to the new C iOS API backend, and it really works well !
I'm currently working at implementing an OpenGLES 2.0 interface for
developing my own custom game renderer, based on what was done before on
the old C API backend.

My main concern is about the way to define the layer class on a UIView. As
you may know, I order to use an OpenGLES 2.0 renderer inside a UIView,
Apple recommend to add this method inside your UIView subclass :

+ (Class) layerClass

{

    return [CAEAGLLayer class];

}


But how to reach the same effect using XMLVM ?
It seems that the UIView implementation is based on a ObjC wrapper class
(UIViewWrapper), but it is generated by XMLVM at XCode project generation,
and it seems I have no way to modify it.
As the method to implement is "static" (class method), I didn't find a way
to "override" it inside my UIView java subclass. Using a delegate method
won't help either.

How can I process to achieve what I want to do ?
Should I do the same way as for the old C iOS API, that's to say duplicate
the UIView class and create a UIViewGL class with specific implementation
using the CAEAGLLayer class ? But then, how can I add the "layerClass"
inside the wrapper implementation, as it is now generated automatically by
the new iOS API ?

[xmlvm-users] Java -> android and iPhone

[Prakash R. <pra...@gm...>]

Hello,

 I am working on a section of library which is written in Java 1.4 version.
Currently our android application and AWT based app is using this library.
We are planning to have this library extended for iPhone application too.
The library dont have any UI components, its just a medium for data
handling and communication with server.

Is it possible to achieve the same using XMLVM? if yes how can i setup java
project and build it to export jar for Android and as binary for iPhone
project.


Thanks

[xmlvm-users] Some precisions about touches events handling

[Mickael B. <mba...@gm...>]

Hi everyone,

Hope you're having a good day right now :)

I have some questions about touches events handling. I just made a few
tests in the last few days and I just wanted to ask you some details :
(FYI, I'm using the C backend)


   - I tried to add UITouch events handling on a regular UIView class. I
   had no success. Then, I tried to debug the MultiTouch tutorial provided
   example and this time, it worked successfully on my iPhone. I couldn't find
   what was wrong on my code, but after many tests, I achieved to make it
   receive events correctly.

It seems that, if you don't implement "drawRect(CGRect)" inside your class
extending UIView, then your class will never receive UITouch events. Well,
you simply have to add this method in your class, even if it does nothing
(you can delete the complete body of this method, it will still work).

Why is it necessary to add this method inside your UIView subclass in order
to receive UITouch events ? It seems that this is not needed on the iOS
official SDK implementation, so maybe you could answer this question.


   - I then tried to add UITouch events handling on a UIViewGL subclass. I
   still had no success at this time, after many tests. I tried almost
   everything, but couldn't make it receive touch events. Do you have any idea
   about how to make it work correctly, or at least, a starting point where to
   search for what's going on ?

My lastest tests made me believe it could be a problem with the
UIViewWrapper / UIViewGLWrapper implementations, but couldn't go further
than this. Any idea ?

Thank you so much for your appreciated help !

[xmlvm-users] Notifications in Android to iPhone cross-compilations

[Mohamed H. <moh...@gm...>]

Hi, I'm considering using XMLVM, I'd like to know though are Notifications
automatically cross-compiled? The API is a bit different, for example how
do I specify that I want a text pop up notification to show up in the
iphone app when there is no such functionality in Android? If I stuck to
functionality that was on both phones, like just having a status bar
notification and playing sounds / vibrating, would that be cross compiled
successfully?

Thanks!

[xmlvm-users] Error trying to build Firework C# demo

[Lino S. <li...@ho...>]

Hi,
 
I am trying to build the CSharp Fireworks (in Visual Studio 2008) example that was included in the packaged downloaded via SVN from sourceforge. However, after building the project successfully, there is a post-build that takes place, but an error occurs. I've listed the error below.... java -classpath ./lib/bcel.jar;./lib/jakarta-regexp.jar;./lib/jdom.jar;./lib/mbel.jar;./lib/saxon9.jar;./lib/xercesImpl.jar;./ org.xmlvm.Main --java --out=./ FireWorks.exe

as a followup to my last message, I would encourage you to use the new
