CADPolyLine CADVertex

[jcasasm]

Hello, in a CADPolyLine figure with Vertex close, how can I identify the CADVertex that is selected by the user

Hello,

Does the user select a CADVertex by a mouse click?

Hello, if the user selects the vertex with the click

Hello, if the user selects the vertex with the click

The selected property of all CADVertex gives me false

Hello,

CADVertex is not an entity and cannot be selected. However, you can determine if some CADVertex was clicked when selecting a CADPolyLine entity with a mouse in CADEditorControl:

Code: Select all

cadEditorControl1.EditorCADPictureBox.MouseDown += EditorCADPictureBox_MouseDown;
...

void EditorCADPictureBox_MouseDown(object sender, MouseEventArgs e)
{
    CADVertex result = new CADVertex();
    result.Point = new DPoint(0, 0, 0);

    DPoint point = cadEditorControl1.GetRealPoint(e.X, e.Y, false, true);
    cadEditorControl1.Image.Selector.UseShiftToAddSelected = true;
    CADEntity entity = cadEditorControl1.Image.Selector.SelectExt(e.X, e.Y, false, true);
    if (entity.EntType == EntityType.Polyline)
    {
        CADPolyLine polyline = entity as CADPolyLine;
        foreach (CADVertex vx in polyline.Vertexes)
        {
            DPoint vxPoint = vx.Point;
            vxPoint.X = Math.Round(vx.Point.X, 4);
            vxPoint.Y = Math.Round(vx.Point.Y, 4);
            if (vxPoint.Equals(point))
            {
                result = vx;
                break;
            }
        }
    }
}
