Check Box
Use the Check Box part to add a control that has two distinguishable states: on and off. This part generates the HTML element input with the type attribute set to checkbox.
To add a Check Box part, select the Web Form Parts Category ( Web Form Parts category icon), then the Check Box part ( Check Box icon). You can also add the part using the Add Part dialog and specifying the class name, AbtHtmlCheckBox.
Check Box Properties
The Check Box part has the following properties:
 
checked
Use the checked property to indicate whether the check box is initially selected.
eventHandlers
Use the eventHandlers property to define any event handlers for this part. Event handlers provide the ability to detect and react to events that occur while an HtmlPage is loaded in a Web browser. An example of an event handler is mouse over, where you can specify when the mouse moves over an HTML element, something happens, usually a JavaScript is executed..
extraAttributes
Use the extraAttributes property to specify any additional HTML attributes that you want included in the HTML tagging generated by the part. You can use this property to include HTML attributes that are not directly supported by VA Smalltalk.
partName
In the Part name field, type the name you want to use to describe the part. For non-visual parts, this text appears under the icon for the part on the free-form surface.
The name of the part can consist of alphanumeric characters, and must be unique from all other parts on the layout surface.
This field is optional. If you do not specify a part name, VA Smalltalk generates a unique name based on the class name of the part.
