範例

下列程式代碼範例示範 方法的實作 GetToolSupported 。

// 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)
{

    // for which support for is being tested. Return false to indicate the
    // tool should be disabled when the associated component is selected.

            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;

備註

如果實作 IToolboxUser 介面的設計工具支援指定的工具，則當這個設計工具有焦點時，工具將會在工具箱中啟用。 否則，會將其停用。 一旦工具標示為已啟用或停用，可能無法再次測試此工具是否支援相同的設計工具。
