GWT ListBox() Java MySql
原标题:GWT ListBox() Java MySql

我从我的Sql表格中选择了记录,并将每个记录列入一个阵列清单。 我正试图将每个数值插入一个位置,即滚落名单箱。

我沉没了。

问题回答

您可以从设在WT的客户方面查阅我的ql数据库。 您需要打上服务器的电话,并将打电话,并将结果交还客户(可能以一组物体(可乘飞机)的形式),然后,你可以添加到下级清单中。

在使用下级清单时,以下法典可能有助于:

public void demo()
{
    VerticalPanel panel = new VerticalPanel();
    panel.addStyleName("demo-panel-padded");
    panel.setSize("200px", "120px");
    panel.add(getListBox(false));
    panel.add(getListBox(true));
    RootPanel.get("demo").add(panel);
}
ListBox getListBox(boolean dropdown)
{
    ListBox widget = new ListBox();
    widget.addStyleName("demo-ListBox");
    widget.addItem("One");
    widget.addItem("Two");
    widget.addItem("Three");
    widget.addItem("Four");
    widget.addItem("Five");
    if(!dropdown)widget.setVisibleItemCount(3);
    return widget;
}
