Detailed Description

CheckBoxButton provides a check box button which user can check or uncheck.

By default, a CheckBoxButton emits a Button::ClickedSignal() signal when the button changes its state to selected or unselected.

The button's appearance could be modified by Button::SetUnselectedImage, Button::SetBackgroundImage, Button::SetSelectedImage, Button::SetSelectedBackgroundImage, Button::SetDisabledBackgroundImage, Button::SetDisabledImage, and Button::SetDisabledSelectedImage.

When the button is not disabled, if it's not selected it only shows the background image. The selected image is shown over the background image when the box is selected (background image is not replaced by selected image).

When the button is disabled, background image and selected image are replaced by disabled images.

Usage example: -

 // in Creating a DALi Application
 void HelloWorldExample::Create( Application& application )
 {
   CheckBoxButton button = CheckBoxButton::New();
   button.SetProperty( Actor::Property::PARENT_ORIGIN, ParentOrigin::CENTER );
   button.SetProperty( Button::Property::LABEL, "Check" );
   button.SetSize( 200, 40 );
   button.SetBackgroundColor( Color::WHITE );
   Stage::GetCurrent().Add( button );

   // Connect to a button signal emitted by the button
   button.StateChangedSignal().Connect( this, &HelloWorldExample::OnButtonStateChanged );
 }

 bool HelloWorldExample::OnButtonStateChanged( Button button )
 {
   // Do something when the button state is changed
   // You can get the state using button.IsSelected() call
   return true;
 }
