IDesignerGlyphProvider Interface

Definição

Namespace:

System.Workflow.ComponentModel.Design

Assembly:

System.Workflow.ComponentModel.dll

Cuidado

The System.Workflow.* types are deprecated. Instead, please use the new types from System.Activities.*

Define o método que classes de provedor de glifo usam para gerar uma matriz de glifos para exibir em um designer de atividade.

Exemplos

O exemplo de código a seguir demonstra como você pode implementar a IDesignerGlyphProvider interface. Ele mostra como você pode implementar o GetGlyphs método para desenhar objetos de glifo personalizados em uma superfície do designer de atividades.

Este exemplo de código faz parte do exemplo do SDK do Monitor de Fluxo de Trabalho do arquivo DesignerGlyphProvider.cs. Para obter mais informações, consulte Monitor de Fluxo de Trabalho.

//Custom glyphprovider used to draw the monitor glyphs on the designer surface
internal class WorkflowMonitorDesignerGlyphProvider : IDesignerGlyphProvider
{
    private Dictionary<string, ActivityStatusInfo> activityStatusList;

    internal WorkflowMonitorDesignerGlyphProvider(Dictionary<string, ActivityStatusInfo> activityStatusList)
    {
        this.activityStatusList = activityStatusList;
    }

    ActivityDesignerGlyphCollection IDesignerGlyphProvider.GetGlyphs(ActivityDesigner activityDesigner)
    {
        ActivityDesignerGlyphCollection glyphList = new ActivityDesignerGlyphCollection();

        //Walk all of the activities and use the 'CompletedGlyph' for all activities that are not 'closed'
        foreach (ActivityStatusInfo activityStatus in activityStatusList.Values)
        {
            if (activityStatus.Name == activityDesigner.Activity.QualifiedName)
            {
                if (activityStatus.Status == "Closed")
                    glyphList.Add(new CompletedGlyph());
                else
                    glyphList.Add(new ExecutingGlyph());
            }
        }

        return glyphList;
    }
}

Comentários

Observação

Este material discute tipos e namespaces obsoletos. Para obter mais informações, consulte Deprecated Types in Windows Workflow Foundation 4.5 (Tipos preteridos no Windows Workflow Foundation 4.5).

Essa interface define o método que a implementação de classes deve usar para fornecer um conjunto apropriado de objetos aos designers de DesignerGlyph atividades. A classe de implementação também deve renderizar os DesignerGlyph objetos no ActivityDesigner objeto .

Métodos

GetGlyphs(ActivityDesigner)

Obsoleto. Retorna uma matriz de glifos associados ao designer de atividade especificado.
