Set Icon to StoreFilterField MenuItem

[slynch]

Hi all,

I have added a StoreFilterField item to a menu:

Menu.add(StoreFilterField)

Similar to the MenuItem where you can apply an icon using the setIcon method, I would like to be able to apply an icon to my StoreFilterField menu item option.

Any possible solutions would be much appreciated.

Thanks,
Susan.

Try to create a new class that extends StoreFilterField and implements IconSupport.

Not sure if that will work, thought.

You can give it a try.

Hi,

I have put the following class together:

public class Filter extends StoreFilterField<Employee> implements IconSupport {

@Override
protected boolean doSelect(final Store<Employee> store, final Employee parent, final Employee record,
final String property, final String filter) {
final Employee emp = record;
final double salary = emp.getSalary();
if (salary < Integer.parseInt(filter)) {
return true;
}
return false;
}

@Override
public AbstractImagePrototype getIcon() {
return this.getIcon();
}

@Override
public void setIcon(final AbstractImagePrototype icon) {
this.setIcon(icon);
}

@Override
public void setIconStyle(final String icon) {
// TODO Auto-generated method stub

}

}

But get the following error:

17:09:41.252 [ERROR] [gwt20project] Uncaught exception escaped
java.lang.StackOverflowError: null

you have the autogenerated methods not right implemented

and with "this.setIcon" you call the same method by yourself ... thats wrong.

best weay: you have to look how other classes in the sourcecode has implemented the IconSupport and make the same with your class.

Exactly...

For example try to copy MenuItem implementations of it...

Hi,

I had implemented a class just like the above description,
and there is a icon next to my storefilterfield menu item.
However, it doesn't looks correct...

Does someone get any idea?

Here is the class code

class ReportDataFilterField extends StoreFilterField<ReportData> implements IconSupport {
        
        private String style;
        protected AbstractImagePrototype icon;

        public ReportDataFilterField() {
              this.style = "x-menu-item";
        }
              
        @Override
        protected boolean doSelect(Store<ReportData> store, ReportData parent,
                ReportData record, String property, String filter) {
            String data = record.get(String.valueOf(field));
            if (data.contains(filter.toLowerCase())) {
                    return true;
            }
            
            return false;
        }

        @Override
        public AbstractImagePrototype getIcon() {
            return icon;
        }

        @Override
        public void setIcon(AbstractImagePrototype icon) {
            if (rendered)
            {
                El oldIcon = el().selectNode(style);
                if (oldIcon != null) {
                    oldIcon.remove();
                }
                if (icon != null) {
                    Element e = icon.createElement().cast();
                    El.fly(e).addStyleName(style);
                    el().insertChild(e, 0);
                }
            }
            this.icon = icon;
        }

        @Override
        public void setIconStyle(String icon) {
            setIcon(IconHelper.create(icon));
        }
        
        @Override
        protected void afterRender() { 
            super.afterRender(); 
            setIcon(icon); 
        } 
    }
