Namespace: DevExpress.Xpf.Docking

Assembly: DevExpress.Xpf.Docking.v24.1.dll

NuGet Package: DevExpress.Wpf.Docking

Declaration

C#

public override void Accept(
    IVisitor<BaseLayoutItem> visitor
)

VB.NET

Public Overrides Sub Accept(
    visitor As IVisitor(Of BaseLayoutItem)
)

Parameters

Name	Type	Description
visitor	DevExpress.Xpf.Layout.Core.IVisitor<BaseLayoutItem>	An object implementing the DevExpress.Xpf.Layout.Core.IVisitor interface.

Remarks

The Accept method lets you recursively iterate through the layout items that belong to the current layout item group and perform a specific operation on the items.

To iterate through the items of a specific layout item group, do the following:

• Create a class implementing the DevExpress.XtraLayout.Utils.BaseVisitor interface;
• Override its Visit method to implement an operation to be performed on layout items;
• Call the group’s Accept method with an instance of the created class as a parameter.

The Visit method will be invoked for the current group first, and then recursively for each child item within the group.
