如何将ClickableTextCells列添加到cellTable

问题描述

|| 大家好 我需要一个简单的示例，向我展示如何将ClickableTextCells列添加到cellTable 谢谢。     

解决方法

Column<YerValueObject,String> newCol = new Column<YerValueObject,String>(new  ClickableTextCell()) {
    @Override
    public String getValue(YearValueObject obj) {
        return obj.someMethod();
    }

};

newCol.setFieldUpdater(new FieldUpdater<YerValueObject,String>() {
    @Override
    public void update(int index,YerValueObject obj,String value) {
        //do whatever you need to here...
    }
});

table.addColumn(newCol,\"ClickColumn\");

    ,如果您需要将clickableTextCell添加到cellTable，这是解决方案

// ClickableTextCell

ClickableTextCell anchorcolumn = new ClickableTextCell();
table.addColumn(addColumn(anchorcolumn,new GetValue<String>() {
        public String getValue(Contact contact) {
            return \"Click \" + contact.anchor;
        }
    },new FieldUpdater<Contact,String>() {
        public void update(int index,Contact object,String value) {
            Window.alert(\"You clicked \" + object.name);
        }
    }),\"Anchor\");



private <C> Column<Contact,C> addColumn(Cell<C> cell,final GetValue<C> getter,FieldUpdater<Contact,C> fieldUpdater) {
        Column<Contact,C> column = new Column<Contact,C>(cell) {

        @Override
        public C getValue(Contact object) {
            return getter.getValue(object);
        }
    };
    column.setFieldUpdater(fieldUpdater);

    return column;
}

private static interface GetValue<C> {
    C getValue(Contact contact);
}


// A simple data type that represents a contact.
    private static class Contact {
        private final String address;
        private final String name;
        private final String anchor;

        public Contact(String name,String address,String anchor) {
            this.name = name;
            this.address = address;
            this.anchor = anchor;
        }
    }

    ,创建一个覆盖

onBrowserEvent

方法的

Column

。 像这样：

new Column<T,String>(new TextCell()) {
    @Override
    public String getValue(T object) {
        return object.getProperty();
    }

    @Override
    public void onBrowserEvent(Context context,Element elem,T object,NativeEvent event) {
        // TODO You can check which event you want to catch
        Window.open(\"http://www.stackoverflow.com\",\"StackOverFlow\",\"\");
    }
};
