Re: Shift/Crtl selection in DefaultNestedTree

[Sven Meier]

Hi,

you should be able to add a dynamic extra attribute:

    protected MarkupContainer newLinkComponent(String id, IModel<T> model)
    {
        return new AjaxLink<Void>(id)
        {
            @Override
            public boolean isEnabled()
            {
                return StyledLinkLabel.this.isClickable();
            }

            @Override
            protected void updateAjaxAttributes(AjaxRequestAttributes 
attributes)
            {
                super.updateAjaxAttributes(attributes);
                                
                attributes.getDynamicExtraParameters().add("function(attrs) { return 
{ 'modifiers' : modifiers(attrs.event) }; }");
            }

            @Override
            public void onClick(AjaxRequestTarget target)
            {
                String modifier = 
getRequest().getRequestParameters().getParameterValue("modifiers").toOptionalString();
            }
        };
    }

I didn't try it, but I think all you have to do is to provide a 
#modifiers(event) to encode all pressed modifier keys.

Have fun
Sven

I have started implementing this :)
Used this [1] as an example

I have one proposal:

To add method updateAjaxAttributes to StyledLinkLabel (to reduce amount of
copy/paste :)), I can create PR, it seems to be trivial :)

And one question:

To have ctrl/shift I need original MouseEvent, how can I get it? (found no
way to debug these dynamic JS functions :( )

Thanks in advance

Sounds doable :)
I was hoping this is already implemented, so I can use it :)
Will implement myself :)

Hi Maxim,

you'd have to transport information about the currently pressed keys to
the server (via AjaxRequestAttributes dynamic extra parameters).

There it is just a matter of managing selection state and visually
marking the components accordingly.

Sounds complicated?

Hello All,

Maybe someone has any working examples of multi-node selection
in DefaultNestedTree using Crtl/Shift keys?

Thanks in advance
