CheckBoxGroup

Use a CheckBoxGroup widget to select from a group of check boxes when a user can make one or more selections. A check mark inside the check box indicates the selection.

To learn how to use this widget programmatically, refer Quantum Visualizer Widget guide.

Important Considerations

The following are important considerations for a CheckBoxGroup Widget.

All Platforms

• A CheckBoxGroup widget is always a group widget.
• Use a CheckBoxGroup widget if there are a limited number of possible selections and you can make more than one selection. If you can make only one selection from the group, use a RadioButtonGroup widget. To display a list of selections, use a ListBox widget.

Android

• If you set the Orientation property to horizontal, do not place more than two items in the group. If you place more than two items and the associated text is large, additional items may not fit in the screen width and will not be visible.

iPhone

• You cannot apply skins in the on-off switch view.

Look Properties

Look properties define the appearance of the widget. The following are the major properties you can set:

• Whether the widget is visible.
• The platforms on which the widget is rendered.
• How the widget aligns with its parent widget and neighboring widgets.
• If the widget displays content, where the content appears.

For descriptions of the properties available on the Look tab of the Properties pane, see Look.

Skin Properties

Skin properties define a skin for the widget, including background color, borders, and shadows. If the widget includes text, you can also specify the text font.

For a CheckBoxGroup widget, you can apply a skin and its associated properties for the following states:

Skin	Definition
Normal	The default skin of the widget.
Focus	The skin applied when the focus is on the widget.

For more information about applying skins, see Understanding Skins and Themes.

CheckBoxGroup Properties

CheckBoxGroup properties specify properties that are available on any platform supported by Quantum Visualizer, and assign platform-specific properties.

Master Data

Specifies the set of values that must be displayed for the user to make a selection from the available choices.

To specify this set of values, click the Edit button of the Master Data field to open the Master Data dialog box.

The Master Data dialog box contains the following columns:

• Key: The unique identifier of each check box.
• Display Value: The label or descriptive text displayed for each check box
• Selected Key: Whether each check box is selected by default. You can select more than one check box.

To add more check boxes to the widget, click Add. To delete a check box, click inside a check box, and then click Delete.

Click Apply to create the master data.

Selected Image

Specifies the image to be displayed when you make a selection.

To provide a default or platform-specific image, click the Edit button to open the Selected Image dialog box.

To provide a platform-specific image or replace the default image, select the platform and click inside the corresponding Value field to open the Selected Image dialog box. You can either:

• Select an available image.
• Provide an image URL.

Unselected Image

Specifies the image to be displayed when a selection is cleared.

To provide a default or platform-specific image, click the Edit button to open the Unselected Image dialog box.

To provide a platform-specific image or replace the default image, select the platform and click inside the corresponding Value field to open the Selected Image dialog box. You can either:

• Select an available image.
• Provide an image URL.

Orientation

Specifies whether the alignment of the check boxes is horizontal or vertical.

Default: Vertical

View Type

For the iOS platform, specifies the view type of the CheckBoxGroup, either Switches, Table, or On-screen Wheel.

Default: Switches

Group Cells

When the view type is Table, specifies whether the Group Cells style is applied. The Group Cells style groups items in the check box group.

Default: The Group Cells style is applied.

Actions

Actions define what happens when an event occurs. On a CheckBoxGroup widget, you can run an action when the following event occurs:

• onSelection: The action is triggered when an item is selected.
• onTouchStart: The action is triggered when the user touches the touch surface. This event occurs asynchronously.
• onTouchMove: The action is triggered when the touch moves on the touch surface continuously until movement ends. This event occurs asynchronously.
• onTouchEnd: The action is triggered when the user touch is released from the touch surface. This event occurs asynchronously.

For more information, see Add Actions.
