            var groups = panel?.Groups;
            if (groups == null) return;
            var bounds = panel.Bounds;
            var groupRight = bounds.X;
            if (groups.Count > 0)
            {
                groupRight = groups[groups.Count - 1].Bounds.Right;
            }
            var logoImage = Properties.Resources.WitswayLogo;
            if (bounds.Height < logoImage.Height) return;
            var logoTop = (bounds.Height - logoImage.Height) / 2;
            var logoLeft = logoImage.Width;
            bounds.X = bounds.Width - logoLeft - 30;
            if (bounds.X < groupRight) return;
            bounds.Width = logoLeft;
            bounds.Y += logoTop;
            bounds.Height = logoImage.Height;
            e.Graphics.DrawImage(logoImage, bounds);
        }

 顶部显示带图标文字的下拉框

效果

代码

            this.barButtonItem6.ActAsDropDown = true;
            this.barButtonItem6.ButtonStyle = DevExpress.XtraBars.BarButtonStyle.DropDown;
            this.barButtonItem6.Caption = "管理员";
            this.barButtonItem6.DropDownControl = this.popupMenu1;
            this.barButtonItem6.Id = 9;
            this.barButtonItem6.ImageOptions.ImageIndex = 0;
            this.barButtonItem6.Name = "barButtonItem6";
            this.barButtonItem6.PaintStyle = DevExpress.XtraBars.BarItemPaintStyle.CaptionGlyph;
            this.barButtonItem6.RibbonStyle = DevExpress.XtraBars.Ribbon.RibbonItemStyles.SmallWithText;

注意

需要将BarButtonItem放到一个BarButtonGroup中

标题栏显示HelpButton

        private void XtraForm1_HelpButtonClicked(object sender, CancelEventArgs e)
        {
            popupMenu1.ShowPopup(MousePosition);
            e.Cancel = true;
        }

设置触摸支持

            DevExpress.XtraEditors.WindowsFormsSettings.SetDPIAware();
            DevExpress.XtraEditors.WindowsFormsSettings.EnableFormSkins();
            DevExpress.XtraEditors.WindowsFormsSettings.AllowPixelScrolling = DefaultBoolean.True;
            DevExpress.XtraEditors.WindowsFormsSettings.ScrollUIMode = DevExpress.XtraEditors.ScrollUIMode.Touch;

            DevExpress.XtraEditors.WindowsFormsSettings.TouchUIMode = TouchUIMode.True;
            DevExpress.XtraEditors.WindowsFormsSettings.TouchScaleFactor =1.5f;

 全局设置RadialMenu中心图标

RadialMenu.DefaultGlyph = Resources.collaboration;
