由于this thread中提供的帮助和建议,我使用Microsoft Ribbon Framework创建了我的第一个非Delphi功能区。
在A.Bouchez在该帖子中发布的guide之后,我设法编译了我的项目并看到了Microsoft功能区。
但是,在执行Command时,我似乎无法让Ribbon响应输入。
我总是使用TActionManager来管理我的事件,所以我需要的是将每个TAction从TActionManager链接到功能区。按照上面链接的教程,我尝试了以下无效:
// 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TA指定给功能区呢?
感谢。
答案 0 :(得分:2)
我发现如何通过查看提供的样本来执行命令(不知道我是如何错过它们的!)。事件似乎必须独立于TActions定义,所以我想这是要走的路。
虽然可以在用于调用功能区的命令的过程中链接Actions OnExecute处理程序,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文件夹将更清晰地展示这一点。可以在此处找到框架:http://www.bilsen.com/windowsribbon/index.shtml
