GUIBaseContext :: highContextExist - Check parent context instance

Implementation overview

• Check parent context
  GUIBaseContext :: highContextExist (  )
• Check high context by resource name
  GUIBaseContext :: highContextExist ( sResource )
• Check high context by name and type
  GUIBaseContext :: highContextExist ( sResource, eContextType )
• Check high context by type
  GUIBaseContext :: highContextExist ( eContextType )

Implementation details

1. Check parent context
   bool GUIBaseContext  :: highContextExist (  )
   

   The function checks, whether the context has a parent context ( true ) or not ( false ).

2. Check high context by resource name
   bool GUIBaseContext  :: highContextExist ( odaba::String &sResource )
   

   The function checks whether the next higher context with the name passed in sResource (window or field name) exists ( true ) or not ( false ).

   • sResource - Name of resoure

     "ok_button"        // button in the current window

     "address.street"   // line edit in the address subwindow

     ".name"            // line edit in the upper control (window)

3. Check high context by name and type
   bool GUIBaseContext  :: highContextExist ( odaba::String &sResource, odaba::ContextTypes eContextType )
   

   The function checks whether the next higher context with the tape passed in eContextType and the name passed in sResource (window or field name) exists ( true ) or not ( false ).

   • sResource - Name of resoure

     "ok_button"        // button in the current window

     "address.street"   // line edit in the address subwindow

     ".name"            // line edit in the upper control (window)

   • eContextType - Context type

     The context type contains the system type of the context instance.

4. Check high context by type
   bool GUIBaseContext  :: highContextExist ( odaba::ContextTypes eContextType )
   

   The function returns whether the next higher context with the type passed in eContextType exists ( true ) or not ( false ).

   • eContextType - Context type

     The context type contains the system type of the context instance.
