Genmodel property "Creation sub-menus" [message #1079543]

Sun, 04 August 2013 15:28

Eclipse User

Hi,

I was looking through the properties of the genmodel and found an boolean attribute called Creation sub-menus. The documentation in the EMF book says:

Quote:

This property determines whether to organize qualified child creation actions into submenus. In the case where an object can have children of the same type via more than one of its features, setting this property to true results in a submenu per feature.

This option might be interesting for me, but I don't really understand the part object can have children of the same type via more than one of its features. Can someone give me an example (metamodel) where this case would match? Or have I to implement the sub-menu by myself in the according itemprovider?

Cheers,
Phil

Phil,

If you have a class X with two references r1 and r2 of class Y, then the
create menu needs to make it clear when creating a child Y whether it
should end up in reference r1 verses r2.

Thx Ed,

that make sense.

Is there a way to implement my own sub-menu for one specific class altough it don't match this case?

For example I have a class X which has a * containment reference to class Y. I would like now to implement a sub-menu inside the Create Child menu of class X where I can choose between different creations of class Y. For example one child creation command would then create a class Y with a specific value, another would set a predefined name attribute and so on.. Is this possible or would it be much effort?

Cheers,
Phil

In the XyzActionBarContributor you could special how the child creation
menus are constructed.

You'd also want to specialize the item providers to create additional
descriptors.

Finally I got it managed to extend my New Child menu. Now it's possible to create childrens of the same class, initialized with different properties. Since the New Child menu has now some entries, I would like to bundle them into a submenu. Is emf supporting this? Maybe the create submenu could be extended to support this?

Cheers,
Phil

There's the Creation Sub-menus property in the GenModel...

The Creation Sub-menus property is set to true but it doesn't work as you can see in the attached image.

Phil,

It only produces qualification if a given type of object can be created
for more than one feature of the class. You'll see your generated item
provider plugin.properties contains properties generated from the
template like this:

_UI_CreateChild_text = {0}
_UI_CreateChild_text2 = {1} <%if (genModel.isCreationSubmenus()) {%>|
<%}%>{0}
_UI_CreateChild_text3 = {1}

You could change all three to look like "{1} | {0}" and then you'll get
submenus for all features with more than one type of child. Check the
behavior of
org.eclipse.example.library.presentation.XyzActionBarContributor.extractSubmenuActions(Collection<IAction>)
to see in the debugger whether it's working as you expect.

Hi Ed,

changing the plugin.properties to:

_UI_CreateChild_text = {1} | {0}
_UI_CreateChild_text2 = {1} | {0}
_UI_CreateChild_text3 = {1} | {0}

hasn't any impact on the menu I mentioned before. There is no submenu although the elements are intances of the same class. Whereas items where I haven't customized the getText method seems to have now an additional submenu (which I don't want btw):

index.php/fa/16041/0/

Unfortunately I couldn't found the method you mentioned using Ctrl-Shift-T.

I don't really understand how the submenu are working, so it's hard for me to find a solution

Can you find the XyzActionBarContributor class?

Hi Ed,

yes I've found that class and the extractSubmenuActions(Collection<IAction>) is every time called except for the one wich has got more than one child instance of the same class. That's weird for me as I can't explain this behaviour. I customized the collectNewChildDescriptors method of this item provider, so that's maybe causing this?

The default one generated looks in my case:

_UI_CreateChild_text = {0}
_UI_CreateChild_text2 = {1} | {0}
_UI_CreateChild_text3 = {1}

changing _UI_CreateChild_text to {1} | {0} provides submenus for all childs except the one I mentioned.

Cheers,
Phil

It could be, but I can't guess at what you might have done there...

I want to achieve that elements are initialized with specific values so I changed collectNewChildDescriptors in this way:

HardwareElement microcontroller = PldFactory.eINSTANCE.createHardwareElement();
microcontroller.setElementType(ElementType.MICROCONTROLLER);

// adding Microncontroller
newChildDescriptors.add(createChildParameter(PldPackage.Literals.HARDWARE_ELEMENT__HARDWARE_ELEMENTS,microcontroller));

HardwareElement core = PldFactory.eINSTANCE.createHardwareElement();
core.setElementType(ElementType.CORE);

// adding Core
newChildDescriptors.add(createChildParameter(PldPackage.Literals.HARDWARE_ELEMENT__HARDWARE_ELEMENTS,core));

and so on...

Another thing what I've done is implementing the getCreateChildText method:

if (child instanceof HardwareElement) {
HardwareElement hw = (HardwareElement) child;
ElementType type = hw.getElementType();

switch (type) {
case MICROCONTROLLER:
	return "Microcontroller";
case CORE:
	return "Core";

and so on...

can you spot any problems which this code?

Yes, keep in mind that the splitting into submenus is based on this
text containing a "|" to separate the name of the submenu from the name
of the item in that submenu; so here you need to ensure you return a
string containing a "|".

That has done the trick, tx Ed!!

As you can see in the attached the sub-menu has no icon. Is it possible to assign an icon to the submenu?

You can specialize
org.eclipse.emf.edit.provider.ItemProviderAdapter.getCreateChildImage(Object,
Object, Object, Collection<?>)

Hi Ed,

that's what I've tried so far. It works for child entries, but for the sub-menu an icon is never displayed, no matter what the method returns.

Phil,

I've never seen a submenu with icons in Eclipse. I'm not sure that's
possible. The generated code doesn't do such a thing, so you'd have to
write that yourself.
