Parâmetros

insertLocation

HitTestInfo

O local no designer para inserir as atividades.

activitiesToInsert

Comentários

Use InsertActivities para inserir uma lista de atividades no local especificado.

Antes de chamar InsertActivities, use CanInsertActivities para garantir que as atividades especificadas possam ser inseridas.

InsertActivities(CompositeActivityDesigner, HitTestInfo, ReadOnlyCollection<Activity>, String)

Insere atividades no designer no local especificado usando uma transação.

public:
 static void InsertActivities(System::Workflow::ComponentModel::Design::CompositeActivityDesigner ^ compositeActivityDesigner, System::Workflow::ComponentModel::Design::HitTestInfo ^ insertLocation, System::Collections::ObjectModel::ReadOnlyCollection<System::Workflow::ComponentModel::Activity ^> ^ activitiesToInsert, System::String ^ undoTransactionDescription);

public static void InsertActivities (System.Workflow.ComponentModel.Design.CompositeActivityDesigner compositeActivityDesigner, System.Workflow.ComponentModel.Design.HitTestInfo insertLocation, System.Collections.ObjectModel.ReadOnlyCollection<System.Workflow.ComponentModel.Activity> activitiesToInsert, string undoTransactionDescription);

static member InsertActivities : System.Workflow.ComponentModel.Design.CompositeActivityDesigner * System.Workflow.ComponentModel.Design.HitTestInfo * System.Collections.ObjectModel.ReadOnlyCollection<System.Workflow.ComponentModel.Activity> * string -> unit

Public Shared Sub InsertActivities (compositeActivityDesigner As CompositeActivityDesigner, insertLocation As HitTestInfo, activitiesToInsert As ReadOnlyCollection(Of Activity), undoTransactionDescription As String)

Parâmetros

compositeActivityDesigner

CompositeActivityDesigner

O designer no qual as atividades serão inseridas.

insertLocation

HitTestInfo

O local no designer no qual as atividades serão inseridas.

activitiesToInsert

ReadOnlyCollection<Activity>

A lista de atividades a ser inserida.

undoTransactionDescription

String

Descrição da transação de designer criada pela inserção.

Exemplos

O exemplo a seguir demonstra a adição de um novo branch usando um designer com base na CompositeActivityDesigner classe. Se CanInsertActivities retornar true, um novo branch será criado usando o InsertActivities método.

protected override CompositeActivity OnCreateNewBranch()
{
    return new ParallelIfBranch();
}

private void OnAddBranch(object sender, EventArgs e)
{
    CompositeActivity activity1 = this.OnCreateNewBranch();
    CompositeActivity activity2 = base.Activity as CompositeActivity;

    if ((activity2 != null) && (activity1 != null))
    {
        int num1 = this.ContainedDesigners.Count;
        Activity[] activityArray1 = new Activity[] { activity1 };

        if (CanInsertActivities(new ConnectorHitTestInfo(this, HitTestLocations.Designer, activity2.Activities.Count),
            new List<Activity>(activityArray1).AsReadOnly()))
        {
            CompositeActivityDesigner.InsertActivities(this,
                new ConnectorHitTestInfo(this, HitTestLocations.Designer, activity2.Activities.Count),
                new List<Activity>(activityArray1).AsReadOnly(),
                string.Format("Adding branch {0}", activity1.GetType().Name));

            if ((this.ContainedDesigners.Count > num1) && (this.ContainedDesigners.Count > 0))
            {
                this.ContainedDesigners[this.ContainedDesigners.Count - 1].EnsureVisible();
            }
        }
    }
}

Protected Overrides Function OnCreateNewBranch() As CompositeActivity
    Return New ParallelIfBranch()
End Function

Private Sub OnAddBranch(ByVal sender As Object, ByVal e As EventArgs)
    Dim activity1 As CompositeActivity = Me.OnCreateNewBranch()
    Dim activity2 As CompositeActivity = CType(MyBase.Activity, CompositeActivity)

    If (activity2 IsNot Nothing) And (activity1 IsNot Nothing) Then

        Dim num1 As Integer = Me.ContainedDesigners.Count
        Dim activityArray1() As Activity = {activity1}

        If (CanInsertActivities(New ConnectorHitTestInfo(Me, HitTestLocations.Designer, activity2.Activities.Count), _
            New List(Of Activity)(activityArray1).AsReadOnly())) Then

            CompositeActivityDesigner.InsertActivities(Me, _
                New ConnectorHitTestInfo(Me, HitTestLocations.Designer, activity2.Activities.Count), _
                New List(Of Activity)(activityArray1).AsReadOnly(), _
                String.Format("Adding branch 0}", activity1.GetType().Name))

            If (Me.ContainedDesigners.Count > num1) And (Me.ContainedDesigners.Count > 0) Then
                Me.ContainedDesigners(Me.ContainedDesigners.Count - 1).EnsureVisible()
            End If
        End If
    End If
End Sub

Comentários

Use InsertActivities para inserir uma lista de atividades na atividade composta.

Antes de chamar InsertActivities, use CanInsertActivities para garantir que a lista especificada de atividades possa ser inserida.
