多亏了this thread提供的帮助和建议,我已经使用Microsoft Ribbon Framework创建了我的第一个非Delphi Ribbon。
根据A.Bouchez在该线程中发布的guide,我已经设法编译了我的项目,并看到了Microsoft Ribbon的运行情况。
但是,我似乎无法让Ribbon在执行命令时响应输入。
我总是使用TActionManager来管理我的事件,所以我所需要的就是将每个TAction从TActionManager链接到功能区。按照上面链接的教程,我尝试了以下方法,但都无济于事:
// actNew is the name of a TAction set in the TActionManager
procedure TfrmMain.actNewExecute(Sender: TObject);
begin
ShowMessage('execute new event');
end;
procedure TfrmMain.CommandCreated(const Sender: TUIRibbon; const Command: TUICommand);
begin
inherited;
case Command.CommandId of
cmdNew: // cmdNew was defined in the Ribbon Designer
begin
// link the ribbon commands to the TActions
actNew.OnExecute(Command as TUICommandAction); // obviously will not work
end;
end;
end;那么,如何将我的TActions分配给功能区呢?
谢谢。

通过查看提供的示例,我了解了如何执行这些命令(不知道我是如何错过它们的!)。这些事件似乎必须独立于TActions来定义,所以我想这就是解决之道。
通过在用于调用功能区命令的过程中链接操作OnExecute处理程序是可能的,例如:
private
CommandNew: TUICommandAction;
procedure CommandNewExecute(const Args: TUICommandActionEventArgs);
procedure UpdateRibbonControls;
strict protected
procedure RibbonLoaded; override;
procedure CommandCreated(const Sender: TUIRibbon; const Command: TUICommand); override;
implementation
procedure TfrmMain.RibbonLoaded;
begin
inherited;
Color:= ColorAdjustLuma(Ribbon.BackgroundColor, -25, False);
UpdateRibbonControls;
end;
// set command states here
procedure TfrmMain.UpdateRibbonControls;
begin
if Assigned(CommandNew) then
CommandNew.Enabled:= True;
end;
// assign the commands
procedure TfrmMain.CommandCreated(const Sender: TUIRibbon; const Command: TUICommand);
begin
inherited;
case Command.CommandId of
cmdNew: // command id defined in the ribbon designer
begin
CommandNew:= Command as TUICommandAction;
CommandNew.OnExecute:= NewExecute;
end;
end;
end;
// command events
procedure TfrmMain.NewExecute(const Args: TUICommandActionEventArgs);
begin
actNew.OnExecute(nil); // < this is calling the event code from a TAction
end;Ribbon Framework中的Samples文件夹将更清楚地说明这一点。框架可以在这里找到:http://www.bilsen.com/windowsribbon/index.shtml
