<checkbox>
The checkbox tag provides a simple toggle button.
The <checkbox> tag provides a simple toggle
button that represents a value of true or
false. It has a disabled state where it does not
respond to mouse events when enabled=false.
Example 1. simple checkbox
<canvas debug="true" height="160">
<debug x="135" y="15"/>
<checkbox id="checkMe" text="Show Green Square"/>
<view visible="${checkMe.value}" bgcolor="green" width="20" height="20"/>
<button text="Toggle" onclick="checkMe.setAttribute('value', !checkMe.value)"/>
<button text="Disable" onclick="checkMe.setAttribute('enabled', false)"/>
<button text="Enable" onclick="checkMe.setAttribute('enabled', true)"/>
<button text="status" onclick="Debug.write('value: '+checkMe.value)"/>
<simplelayout axis="y" spacing="4"/>
</canvas>
Note that checkbox attributes may be used as constraints for other attributes.
In the example above, clicking the checkbox toggles the visibility of the
green square. Whenever the value of the checkbox changes, so does the
visibility attribute of the green view.
