Vaadin 10 对话框不显示
Vaadin 10 Dialog doesn't show up
我看不到我的 Vaadin Dialog
,我正在尝试添加一个简单的 Vertical Layout
这是我的代码:
Dialog d = new Dialog(new Label("Simple label"));
d.setCloseOnEsc(false);
d.setCloseOnOutsideClick(false);
Button cancelBtn = new Button("Cancel", event -> {
d.close();
});
d.add(cancelBtn);
add(d);
我希望有人能帮助我:)
Dialog::open
A Dialog
is a specific component - it is not normally rendered within the given container, but opens as a popup. Therefore, it has special semantics to make it to render - after creating a dialog, you have to call dialog.open()
使其显示。
这也不是 Vaadin 特有的 - 在许多框架中,对话框(和其他弹出窗口)以特殊方式显示 - 这有点像一种模式。
