/* This class implements the monostable 'push button' widget. When the user taps 
   on the button, the button sends a signal to the slot method stored in its @OnActivate 
   property. By connecting further slot methods to the properties @OnPress, @OnRelease, 
   @OnEnter and @OnLeave you can react to other events triggered while the user 
   interacts with the button.
   During its lifetime the button remains always in one of the four states: 'disabled', 
   'default', 'focused' and 'active'. The state 'disabled' is true for every not 
   available button (the property @Enabled of the button is 'false'). Such buttons 
   will ignore all user inputs. The state 'default' determines a button, which is 
   ready to be touched by the user or ready to become focused. As soon as the button 
   becomes focused, it switches in the state 'focused'. In this state the user can 
   activate the button by pressing a key on the keyboard. Finally, the state 'active' 
   is true, if the user actually interacts with the button (the button is pressed).
   The exact look and feel of the push button is determined by the 'Push Button 
   Configuration' object assigned to the property @Appearance. The configuration 
   object provides bitmaps, colors, fonts and other configuration parameters needed 
   to construct and display the push button. Usually, you will manage in your project 
   your own configuration objects and customize the push buttons according to your 
   design expectations. Depending on the information provided in the associated 
   configuration object, the push button will be composed of following views:
   - 'Face' is a bitmap frame view (Views::Frame) filling per default the entire 
   background of the button. In the configuration object you can individually specify 
   for every button state the desired bitmap, its opacity, frame number (if the 
   bitmap is multi-frame) and tint color (if the bitmap contains Alpha8 information 
   only). The button can automatically play animated bitmaps. If desired, you can 
   also configure the bitmap to be arranged horizontally and vertically instead 
   of filling the entire widget area.
   - 'Icon' is an image view (Views::Image) displayed per default in the center 
   of the button. The corresponding bitmap is determined in the property @Icon. 
   If the bitmap is multi-frame, the desired frame number can be selected by using 
   the property @IconFrame or individually for every button state by using the properties 
   @IconFrameActive, @IconFrameDefault, @IconFrameDisabled and @IconFrameFocused. 
   In the configuration object you can specify the alignment and margins how to 
   arrange the @Icon bitmap within the button area. Furthermore, for every button 
   state the opacity and tint color (if the @Icon bitmap contains Alpha8 information 
   only) can be determined. The button can automatically play animated bitmaps.
   - 'Label' is a text view (Views::Text) displayed per default in the center of 
   the button. The corresponding text is determined in the property @Label. In the 
   configuration object you can specify the font, alignment and margins to use for 
   the text view. For every button state you can specify individual text color values.
   In particular application cases you can instruct the button to automatically 
   resign and retarget the actual touch interaction to another touch handler (e.g. 
   another widget) after the user has performed a horizontal wipe gesture (@ResignAfterHorizontalWipe) 
   or vertical wipe gesture (@ResignAfterVerticalWipe). Using these properties several 
   widgets can cooperate during an active user interaction even if these handler 
   overlap each other.
   If the button is actually focused, it can also be activated by pressing the keyboard 
   key Core::KeyCode.Enter. In the configuration object you can specify another 
   key code, if desired. To prevent the button from being able to be focused, specify 
   in the configuration object the Core::KeyCode.NoKey as the code to activate the 
   button.
   For more details regarding the customization of the button see the description 
   of WidgetSet::PushButtonConfig class. */

/* The method UpdateViewState() is invoked automatically after the state of the 
   component has been changed. This method can be overridden and filled with logic 
   to ensure the visual aspect of the component does reflect its current state. 
   For example, the 'enabled' state of the component can affect its colors (disabled 
   components may appear pale). In this case the logic of the method should modify 
   the respective color properties accordingly to the current 'enabled' state. 
   The current state of the component is passed as a set in the parameter aState. 
   It reflects the very basic component state like its visibility or the ability 
   to react to user inputs. Beside this common state, the method can also involve 
   any other variables used in the component as long as they reflect its current 
   state. For example, the toggle switch component can take in account its toggle 
   state 'on' or 'off' and change accordingly the location of the slider, etc.
   Usually, this method will be invoked automatically by the framework. Optionally 
   you can request its invocation by using the method @InvalidateViewState(). */
