column1.addWidget(widgetId);
}
public void addTextWidget(ActionEvent event)
{
UIComponent dashboardPanel = FacesContext.getCurrentInstance().getViewRoot().findComponent("dashboardForm:dashboardPanel");
Panel panel = new Panel();
InputText textWidget = new InputText();
int childCount = dashboardPanel.getChildCount();
String widgetId = "widget" + String.valueOf(childCount);
panel.setId(widgetId);
panel.getChildren().add(textWidget);
addWidget(widgetId);
dashboardPanel.getChildren().add(panel);
}
public void handleReorder(DashboardReorderEvent event)
{
}
}
推荐答案
确定，然后使面板可拖动，需要设置面板标题，因此在addTextWidget方法中，我必须做类似的事情
OK then to make the panels draggable the panels header needs to be set, so in the addTextWidget method I had to do something like
panel.setHeader(widgetId);
