Hello,
I'm trying to extend VE and make a GUI builder for a framework we use on my
job. For now I made a component that can be chosen in new visual class
wizard and I made a javajet file that generates the code for a component,
that looks like that:
public class MyClass extends MyComponent{
public MyComponent()
{
buildUI();
}
private void buildUi()
{
buildComponents();
buildLayout();
}
private void buildComponents()
{
}
private void buildLayout()
{
GridBagLayoutHelper helper = new GridBagLayoutHelper(this);
}
}
But now I would like three things to hapen when i add new component to
MyComponent:
1.create new private variable of added component,
2. add line in buildComponents() that looks like this: newComponent =
MafFactory.createNewComponent();
3. add a line in buildLayout() that uses helper class and looks like that:
helper.add(newComponent);
For now as much as I understand extending VE this means it has to be done by
making a decoder and decoder helper which use AST as it was mentioned in
"Enabling support for custom widget" tutorial.
The problem is that I dont understand how can i get AST in method generate()
that is implemented in AbstractExpressionDecoder. So I wonder, is it right
for me to extend AbstractExpressionDecoder and SimpleAttributeDecoderHelper
to get the wanted result or is there some other way to achive that.
Also I would like to know when will you write a code generation tutorial?
Thank you,
Danijel

Hi Danijel,
Sorry for the late response. We were in the middle of a testpass.
Generally we add the dropped component as a child of the component on
which we drop. In your case, the added component should be a child of
some property bean (layout helper). I think this would require some GEF
edit policies on the component on which you are dropping, to basically
generate commands which make necessary changes to the model. Once the
changes are made to the model, codegen would be invoked to generate
appropriate statements in the methods.
By default VE has a code pattern where there is an 'initialize()'
method ['buildUI()' in your case], which adds all the child components
in Swing. However there is no helper class which adds the children
acoording to some layout.
Regards,
Sri.

it looks like I dont hav any idea how to get CompilationUnitEditor after
all.
I'm staring in ObjectDecoder and somhow I thot that the method generate
would lead me to CompilationUnitEditor, but no.
Please can you tell me in feu steps how would you do the thing I want to do
in few stwps.
Would you use ObjectDecoder and ExpressionDecoderHelper or would you do it
in a different way (if so, how)?

must be some basic methods generate() and decode() that is called when a
component is dropped on some other component and does not depend on java
coding style. Is it a must to use ObjectDecoder and ExpressionDecoderHelper
(or classes that implement IExpressionDecoder and IExpressionDecoderHelper)?
If so, how would direct me to build a Delphi GUI builder?
Please do some tutorials, we are waiting long enough. This is sily alredy,
you are making new features but noone has even understanding old ones. I'm
shure that there is lots of people looking at your homepage every day for
months, waitng to get some tutorials. You dont need to do prety tutorials
with lots of pictures just do case studyes in 10-20 centances (if you want
to do this you should start with this and uste that...) and all those fancy
tutorials will be made by others.
I hope you wont take this as a critique, becouse this is just a post from
desperate person looking day by day in your code with no progress.
Thank you,

Hi Danijel,
Apologies once again for the late response. We have been working heads
down with the VE 1.1 M1 effort. I was wondering as to why you would need
the CompilationUnitEditor? When a generate() is called we put the code
into the CompilationUnit - is that what you are looking for? The
ICompilationUnit can be got from IBeanDeclModel.getCompilationUnit().
The IBeanDeclModel is basically codegen's model containing references to
all the methods, beans, expressions etc.
If you would like to insert the content of an expression into a method,
please look at CodeExpressionRef.insertContentToDocument(). All the
decoders insert expressions via this API.
Regards,
Sri.

When you drop an object, the source/target policies generate a command to insert the object into the VE's (EMF) model.
The commands will determine (generally) the following:
o What object to drop, and how to construct it ('allocation' feature)
o What is the scope of this object (is it an instance variable, vs. local and such)
o What to name this object
o Set (if needed) properties/events
The CodeGeneration in VE listens to changes in the model:
o When a new object is dropped, it will pick up a Decoder for it. You can
use the override files to specify a decoder for a particular class.
see the VE tutorial for more detail of specifying decoders
http://dev.eclipse.org/viewcvs/indextools.cgi/%7Echeckout%7E /org.eclipse.ve.examples/org.eclipse.ve.example.customwidget /WebContent/index.html#Overriding_an_Expression_Decoder
A single decoder will be used for a particular property (source expression).
A decoder has a decode()/generate() methods, see SWTControlDecoder() as an example,
and put a breakpoint in any of these methods
btw. you can get at a CU from a decoder by doing the following:
Decoders typically have access to a IBeanDeclModel as an instance variable.
IBeanDeclModel.getCompilationUnit() will give you the CU.

You are not required to used an ObjectDecoder, but it does performs many of the basic tasks, and extending it will make
your life easier.
I do not have much experience with Delphi GUI builder. What is exactly that the current decoders can not do for you?

Not at all. There is a tutorial (noted above), but it may not be deep enough for what you need for codegen.
Note that in general, VE's code gen assume a single method to have all the settings that are associated with a given
bean; it is called the init method, and it is the method that constructs the bean (constructor, or factory).
For a factory construction, VE at this point will only parse a Static method as to eliminate reverse parsing of dynamic
logic that is not modeled.

Hi Denijel, I'm trying to extend VE to use Thinlets. I'm a fresh plugin
developer, could you please send me your project as it is? just for
understand a litle more about ve extensions.
Thanks and sorry for can not help you now.

Hello,
it looks like I dont hav any idea how to get CompilationUnitEditor after
all.
I'm staring in ObjectDecoder and somhow I thot that the method generate
would lead me to CompilationUnitEditor, but no.
Please can you tell me in feu steps how would you do the thing I want to do
in few stwps.
Would you use ObjectDecoder and ExpressionDecoderHelper or would you do it
in a different way (if so, how)?
Thank you,
Danijel

Hello,
I would really nead to know if there is any starting point for custom code
generating without using swt code generator. I somehow beleave that there
must be some basic methods generate() and decode() that is called when a
component is dropped on some other component and does not depend on java
coding style. Is it a must to use ObjectDecoder and ExpressionDecoderHelper
(or classes that implement IExpressionDecoder and IExpressionDecoderHelper)?
If so, how would direct me to build a Delphi GUI builder?
Please do some tutorials, we are waiting long enough. This is sily alredy,
you are making new features but noone has even understanding old ones. I'm
shure that there is lots of people looking at your homepage every day for
months, waitng to get some tutorials. You dont need to do prety tutorials
with lots of pictures just do case studyes in 10-20 centances (if you want
to do this you should start with this and uste that...) and all those fancy
tutorials will be made by others.
I hope you wont take this as a critique, becouse this is just a post from
desperate person looking day by day in your code with no progress.
Thank you,
Danijel

Hi Danijel,
Apologies once again for the late response. We have been working heads
down with the VE 1.1 M1 effort. I was wondering as to why you would need
the CompilationUnitEditor? When a generate() is called we put the code
into the CompilationUnit - is that what you are looking for? The
ICompilationUnit can be got from IBeanDeclModel.getCompilationUnit().
The IBeanDeclModel is basically codegen's model containing references to
all the methods, beans, expressions etc.
If you would like to insert the content of an expression into a method,
please look at CodeExpressionRef.insertContentToDocument(). All the
decoders insert expressions via this API.
Regards,
Sri.

When you drop an object, the source/target policies generate a command to insert the object into the VE's (EMF) model.
The commands will determine (generally) the following:
o What object to drop, and how to construct it ('allocation' feature)
o What is the scope of this object (is it an instance variable, vs. local and such)
o What to name this object
o Set (if needed) properties/events
The CodeGeneration in VE listens to changes in the model:
o When a new object is dropped, it will pick up a Decoder for it. You can
use the override files to specify a decoder for a particular class.
see the VE tutorial for more detail of specifying decoders
http://dev.eclipse.org/viewcvs/indextools.cgi/%7Echeckout%7E /org.eclipse.ve.examples/org.eclipse.ve.example.customwidget /WebContent/index.html#Overriding_an_Expression_Decoder
A single decoder will be used for a particular property (source expression).
A decoder has a decode()/generate() methods, see SWTControlDecoder() as an example,
and put a breakpoint in any of these methods
btw. you can get at a CU from a decoder by doing the following:
Decoders typically have access to a IBeanDeclModel as an instance variable.
IBeanDeclModel.getCompilationUnit() will give you the CU.

You are not required to used an ObjectDecoder, but it does performs many of the basic tasks, and extending it will make
your life easier.
I do not have much experience with Delphi GUI builder. What is exactly that the current decoders can not do for you?

Not at all. There is a tutorial (noted above), but it may not be deep enough for what you need for codegen.
Note that in general, VE's code gen assume a single method to have all the settings that are associated with a given
bean; it is called the init method, and it is the method that constructs the bean (constructor, or factory).
For a factory construction, VE at this point will only parse a Static method as to eliminate reverse parsing of dynamic
logic that is not modeled.
