在java中性别是单选按钮,如何把性别添加到数据库中

参考技术A 一般是用枚举,String也可以,但是要做处理。我一直在用枚举 参考技术B sex = request.getParameter("sex");//(sex)为id 参考技术C 用整数1、0表示,或者用枚举

如何将单选按钮添加到菜单项?

【中文标题】如何将单选按钮添加到菜单项?【英文标题】:How do You Add Radio Buttons To Menu Items? 【发布时间】:2013-02-05 10:45:48 【问题描述】:

我想在我的菜单项中添加单选按钮。

我已经看到一些人们将单选按钮作为菜单项的答案。但我希望我的菜单项具有正确的单选按钮,可以在 Winforms 中轻松完成。

为确保我得到的答案与其他人不同,下面是菜单项单选按钮的外观图片:

顺便说一下,我使用的是 C#,WPF。

【问题讨论】:

你见过这个吗? ***.com/questions/6253145/… @Neil Mitchell:如果您需要支持其他主题,例如 Luna、Aero、Classic 等,可能需要为每个主题样式创建。每个主题都需要为每个主题携带一个样式。这适合你吗?我的意思是,最好专注于功能和单选按钮,至少为他制作一个通用的样式。然后,如果您需要能够使其适合您的风格。如果我或其他人会给你一个单一样式和单选按钮的解决方案,它会来找你吗? @AnatoliyNikolaev 这个问题只与样式有关 - 编写功能非常简单。我想要的是一种利用主题中已有内容的方法,而不是编写新的样式元素。可能是 WPF 没有为单选菜单按钮定义样式,或者我只是无法正确获取样式。当然,底层操作系统(不是 WPF)确实定义了单选菜单样式。 【参考方案1】:

【讨论】:

感谢您的信息。 点击菜单几次后,需要点击两次才能选择未选中的菜单项。【参考方案2】:

您可以通过更改控件的模板属性来更改控件的外观:

            <MenuItem>
                <MenuItem.Template>
                    <ControlTemplate>
                        <RadioButton>Radio</RadioButton>
                    </ControlTemplate>
                </MenuItem.Template>
            </MenuItem>

编辑:使用 RadioButton 作为 MenuItem-Icon,以获得图片中显示的外观:

                <MenuItem Header="Hallo">
                    <MenuItem.Icon>
                        <RadioButton/>
                    </MenuItem.Icon>
                </MenuItem>

【讨论】:

我曾经编写过您所拥有的代码,但它正在制作一个单选按钮,而不是在菜单项文本的右侧有一个带有圆圈的方形框。能否请您提供一些代码,使相同的单选按钮在正方形中有一个圆圈,如我的图片所示?
