这个应用程序需要表单上已经有一个TPopupActionBar组件。应用程序创建一个action manager组件,并将一个图像列表分配给它的一些属性。然后,自定义弹出action bar 并将其assigned to表单的PopupMenu属性。右击表单显示弹出菜单。
Code
procedure TForm1.FormCreate(Sender: TObject);var
Images: TImageList;
Image: TBitmap;
ActionManager: TActionManager;
Option1, Option2: TMenuItem;begin
// display an information message
ShowMessage('Right click the form to display the customized popup menu');
// create an image list
Images := TImageList.Create(self);
Images.Height := 32;
Images.Width := 32;
try
Image := TBitmap.Create;
Image.Height := 32;
Image.Width := 32;
Image.Canvas.Font.Name := 'Times New Roman';
Image.Canvas.Font.Size := 22;
Image.Canvas.TextOut((Image.Width - Image.Canvas.TextWidth('1')) div 2, 0, '1');
Images.Add(Image, nil);
finally
Image.Free;
end;
// create an action manager and assign the image list to some of its properties
ActionManager := TActionManager.Create(self);
ActionManager.DisabledImages := Images;
ActionManager.LargeDisabledImages := Images;
ActionManager.LargeImages := Images;
// add some items to the popup menu associated with the popup action bar
Option1:= TMenuItem.Create(self);
Option1.Caption := 'New';
PopupActionBar1.Items.Add(Option1);
Option2:= TMenuItem.Create(self);
Option2.Caption := 'Save';
PopupActionBar1.Items.Add(Option2);
// let the popup action bar be the form's popup menu
Form1.PopupMenu := PopupActionBar1;end;翻译由网淘巴完成,转载必须标明出处:ActnMgrBar 使用实例_delphi_网淘巴 (wtao8.com)
