Ejemplos

En el ejemplo de código siguiente se muestra una implementación del GetToolSupported método .

// This method can signal whether to enable or disable the specified
// ToolboxItem when the component associated with this designer is selected.
bool IToolboxUser::GetToolSupported( ToolboxItem^ tool )
{
   
   // Search the blocked type names array for the type name of the tool
   // for which support for is being tested. Return false to indicate the
   // tool should be disabled when the associated component is selected.
   for ( int i = 0; i < blockedTypeNames->Length; i++ )
      if ( tool->TypeName == blockedTypeNames[ i ] )
               return false;

   
   // Return true to indicate support for the tool, if the type name of the
   // tool is not located in the blockedTypeNames string array.
   return true;
}

// This method can signal whether to enable or disable the specified
// ToolboxItem when the component associated with this designer is selected.
bool IToolboxUser.GetToolSupported(ToolboxItem tool)
{       
    // Search the blocked type names array for the type name of the tool
    // for which support for is being tested. Return false to indicate the
    // tool should be disabled when the associated component is selected.
    for( int i=0; i<blockedTypeNames.Length; i++ )
        if( tool.TypeName == blockedTypeNames[i] )
            return false;
    
    // Return true to indicate support for the tool, if the type name of the
    // tool is not located in the blockedTypeNames string array.
    return true;
}

Comentarios

Si el diseñador admite la herramienta especificada que implementa la IToolboxUser interfaz, la herramienta se habilitará en el cuadro de herramientas cuando este diseñador tenga el foco. De lo contrario, se deshabilitará. Una vez que una herramienta está marcada como habilitada o deshabilitada, es posible que no se vuelva a probar la compatibilidad con el mismo diseñador.
