Hello,
i'd like to extend some components with the ability to render certain nodes
with an additional attribute which is then picked up in JS and used as a
keybinding for shortcuts.
So far i created a mixin which i preferably would like to put on any kind of
component, in case of an EventLink it should simply render:
link
instead of:
link
This works like expected but a problem comes up with components that contain
components, for example:
public class MyComponent
{
@Component(//parameters)
private EventLink edit;
... more stuff in here
}
Now i'd like to use 'MyComponent' on different pages where on some pages i'd
like to use the mixin whereas on others i don't. I also don't want to change
the component and add the mixin in the component and a parameter to control
if it should be active or not.
When debugging i found the rendered elements are available in class
RenderQueueImpl in the Stack<ComponentResources> renderingComponents, other
than that i couldn't find any appearance and don't know if or how to inject
or access the element.
I'd like to pass the component name and optionally the container
component(s) in a fashion like:
'myComponent.edit' where myComponent is the variable name as in:
@Component
private MyComponent myComponent;
to my mixin.
Is there any way i can filter the rendered element in the render phases?
@BeginRender
void beginRender(final MarkupWriter markupWriter)
{
markupWriter.addListener(new MarkupWriterListener()
{
@Override
public void elementDidEnd(final Element element)
{
/**
* here i'd like to put my if(element == parameter)
* where element is the currently rendered component
* and parameter is the passed parameter somhow in the
* fashion of containerName.componentName
*/
element.attribute(ATTRIBUTE_NAME, shortcut);
}
@Override
public void elementDidStart(Element element)
{
}
});
}
