Checkbox Widgets

复选框部件

In a user input form, a checkbox gives the user a binary choice. A checkbox can be used for a single choice, like whether or not to subscribe to a newsletter, or in a situation where the user can select several of many possible choices, like choosing from many pizza toppings in an order form.

在用户输入表单中，复选框给用户一个二进制选择。复选框可用于单个选择，例如是否订阅时事通讯，或者用于用户可以从许多可能的选择中选择几个选项的情况，例如在订单表单中从许多比萨配料中进行选择。

1、Box Size and Alignment

箱体尺寸与对齐

In the Button section of the Style pane, you can use the Size field to set the width and height of the box portion of the checkbox.

在 Style 窗格的 按钮 部分，您可以使用 Size 字段设置复选框的框部分的宽度和高度。

By default, the box portion of a checkbox is on the left, and the label text is on the right. To swap the order so that the text is on the left and the box is on the right, use the Align icons to the right of the Size field.

默认情况下，复选框的框部分位于左侧，标签文本位于右侧。要交换顺序，使文本位于左侧而框位于右侧，请使用 Size 字段右侧的 Align 图标。

2、Editing the Label Text

编辑标签文本

You can edit the text on a checkbox widget's label via any of the options below:
你可以编辑文本的复选框小部件的标签通过以下任何选项:

• Double-click the checkbox label to enter text-editing mode

  *选择复选框标签并开始输入。(此选项仅在您禁用单键快捷方式时可用

3、Checked by Default

默认选中状态

By default, a checkbox begins in its unchecked state when the page first loads in the web browser. To instead have a checkbox begin in its checked state, select the checkbox and click its box on the canvas. You can also check the Selected option in the More Properties menu in the Interactions pane.

默认情况下，当页面首次在web浏览器中加载时，复选框开始处于未选中状态。要使复选框以其选中状态开始，请选中复选框并在画布上单击其框。您也可以在 互动 窗格中的 More Properties 菜单中检查 Selected 选项。

4、Special Interactions

在web浏览器中，您可以单击复选框进行选中和取消选中。

You can also dynamically check and uncheck a checkbox with the Set Selected/Checked action . The true value option will check the checkbox, and the false option will uncheck it. The toggle option will set the checkbox to the opposite of the state it's in when the interaction occurs.

您还可以使用 Set Selected/Checked action动态地选中和取消选中复选框。 true value选项将选中复选框， false 选项将取消选中。 toggle 选项将把复选框设置为与交互发生时的状态相反的状态。

4.2、## Capturing and Evaluating the Checked State
