CheckBox Class

In This Topic

Represents a check box control. This is an abstract class.

Syntax

Visual Basic (Declaration)

public abstract class CheckBox : Button, System.ComponentModel.INotifyPropertyChanged

Public MustInherit Class CheckBox 
   Inherits Button
   Implements System.ComponentModel.INotifyPropertyChanged

Remarks

All ribbon control elements share several attributes. The loadOnClick attribute determines when the control should be created by the framework. By default, controls appear enabled, but are not actually instantiated until they are clicked. This simple just-in-time (JIT) strategy improves resource utilization and startup time by deferring the instantiation of controls until they are initiated by the end user. Note that non-visible controls are never loaded until they become visible (or are executed programmatically), regardless of the value assigned to loadOnClick.

Tooltips are defined using the tooltip sub-element and may span as many lines as necessary. The image attribute is used to supply an image that will appear next to the tip text. Command tooltips also support a disabledText element, this string is additional displayed when the command is disabled.

Most controls support multiple sizes in the ribbon. For example, a button can render small (small icon only), medium (small icon with text), and large (large icon over text). Use the smallImage and largeImage attributes to specify unique images for the different sizes. Images don’t have to be graphics, you can also use XAML. You can also use overlayLargeImage and overlaySmallImage to draw a graphic or XAML overtop of the corresponding images. If the image should flip when running right-to-left, e.g. arrow buttons, set the flipImageRTL attribute to true.

The disableIfBusy element is used to signal that the control should be disabled whenever the primary worker thread is busy. This prevents work from queuing up. This element is true by default. Controls that always need to be enabled such as the close application button should set this to false.

All control declarations support a condition attribute allowing the assignment of a condition. If the specified condition isn’t met, the control will be automatically disabled by the framework. In addition, controls remain unloaded until their is met. If no condition is specified, the control is assumed to be always relevant.

Controls can also be registered into component categories using the categoryRefID attribute. In this scenario, you can additionally use the content sub-element to define any custom data. For example, the Editing module may define a component category for 'sketch tools' and your custom sketch tool would need to be registered in this category for it to appear in their custom tool palette.

Declaring Checkboxes in DAML:

            <checkBox id="acme_labelClassEnableCheckBox" 
                         condition="acme_labeledLayerSelectedCondition" 
                         caption="Label Features In This Class" 
                         className="LabelClassEnableCheckBox">
              <tooltip heading="">Label the features defined by the current label class.</tooltip>
            </checkBox>
