Answer 1

OOTB 로고는 180px x 64px이므로 이미지를 최상의 방법으로 표시 할 비율이 있어야합니다 (OOTB 로고처럼).

이미지를 ootb 이미지와 동일한 비율로 자르면됩니다.

렌더링을 수정하여 적어도 .ms-siteicon-img CSS 클래스 를 무시 해야하는 로고 형식을 덮어야합니다.

오늘이 클래스는 를 적용합니다.

display:block;
max-height: 64px;
max-width: 180px;

.

이미지의 원인이 당신이 wnat 로 렌더링되지 않는 것입니다.

Make sure the table has yourTable.setMultiSelect(true) and then just iterate the ID's got from yourTable.getItemIds() and call yourTable.select(id) for all id's. This is one way.

Answer 3

In Vaadin 7 when you have table with container data source you can do this:

table.setValue(container.getItemIds());

In Vaadin 6 works this for me:

public void selectAll() {
    int size = table.getItemIds().size();
    for(int i = 0; i < size; i++) {
        table.select(i);
    }
    table.requestRepaint();
}

And of course in both Vaadin versions don't forget to these lines:

table.setSelectable(true);
table.setMultiSelect(true);

You can simply do it by

Table table = new Table(); 
table.setValue(table.getItemIds());

It should not cause performance troubles instead you have few hundreds rows. In case you have - bad architecture.

Also you can just iterate through the list (Vaadin does the same) Here you can find how to reverse selected list using simple iteration. In two words:

            Collection<Object> toSelect = new ArrayList<Object>();
            for (Iterator<?> it = simpleTable.getItemIds().iterator(); it.hasNext(); )                 {
                Object next = it.next();
                if (!((Collection<?>) simpleTable.getValue()).contains(next))
                    toSelect.add(next);
            }
            simpleTable.setValue(toSelect);
