Detailed Description

A PushButton changes its appearance when is pressed and returns to its original when is released.

By default, a PushButton emits a Button::PressedSignal() signal when the button is pressed, a Button::ClickedSignal() signal when it's clicked. and a Button::ReleasedSignal() signal when it's released or having pressed it, the touch point leaves the boundary of the button.

Usage example: -

 // in Creating a DALi Application
 void HelloWorldExample::Create( Application& application )
 {
   PushButton button = PushButton::New();
   button.SetProperty( Actor::Property::PARENT_ORIGIN, ParentOrigin::CENTER );
   button.SetProperty( Button::Property::LABEL, "Press" );
   Stage::GetCurrent().Add( button );

   // Connect to button signals emitted by the button
   button.ClickedSignal().Connect( this, &HelloWorldExample::OnButtonClicked );
   button.PressedSignal().Connect( this, &HelloWorldExample::OnButtonPressed );
   button.ReleasedSignal().Connect( this, &HelloWorldExample::OnButtonReleased );
 }

 bool HelloWorldExample::OnButtonClicked( Button button )
 {
   // Do something when the button is clicked
   return true;
 }

 bool HelloWorldExample::OnButtonPressed( Button button )
 {
   // Do something when the button is pressed
   return true;
 }

 bool HelloWorldExample::OnButtonReleased( Button button )
 {
   // Do something when the button is released
   return true;
 }

See Button for more details on signals and modifying appearance via properties.
