如何使用Glue将Visio形状仅连接到矩形侧边标记中点

当前代码将连接器粘接到形状的Pin点（通常为形状中心），要实现粘接到矩形侧边中点，可通过两种方式修改：

方法1：通过形状边界公式计算中点 #

矩形的侧边中点可通过Pin点坐标结合宽高计算，对应Visio单元格公式如下：

• 上边中点：PinX, PinY + Height*0.5
• 下边中点：PinX, PinY - Height*0.5
• 左边中点：PinX - Width*0.5, PinY
• 右边中点：PinX + Width*0.5, PinY

修改后的代码示例：

// Drop Shape
Visio.Master visioMaster = visioStencil.Masters.get_ItemU(@"Rectangle");
Visio.Shape visioShape = visioPage.Drop(visioMaster, 0.0, 0.0);

Visio.Master visioMaster1 = visioStencil.Masters.get_ItemU(@"Rectangle");
Visio.Shape visioShape1 = visioPage.Drop(visioMaster1, 0.0, 1.0);

// Add a dynamic connector to the page using glue.
Visio.Shape vsoConnectorShape = visioShape.ContainingPage.Drop(app.ConnectorToolDataObject, 0.0, 0.0);

// Set the connector properties, using different arrows, colors, and patterns for many-to-many relationships.

// 连接起点到第一个矩形的上边中点
Visio.Cell cellBeginX = vsoConnectorShape.get_CellsSRC(1, (short)Visio.VisRowIndices.visRowXForm1D, (short)Visio.VisCellIndices.vis1DBeginX);
cellBeginX.GlueTo(visioShape.get_CellsU("PinX"));
Visio.Cell cellBeginY = vsoConnectorShape.get_CellsSRC(1, (short)Visio.VisRowIndices.visRowXForm1D, (short)Visio.VisCellIndices.vis1DBeginY);
cellBeginY.GlueTo(visioShape.get_CellsU("PinY+Height*0.5"));

// 连接终点到第二个矩形的下边中点
Visio.Cell cellEndX = vsoConnectorShape.get_CellsSRC(1, (short)Visio.VisRowIndices.visRowXForm1D, (short)Visio.VisCellIndices.vis1DEndX);
cellEndX.GlueTo(visioShape1.get_CellsU("PinX"));
Visio.Cell cellEndY = vsoConnectorShape.get_CellsSRC(1, (short)Visio.VisRowIndices.visRowXForm1D, (short)Visio.VisCellIndices.vis1DEndY);
cellEndY.GlueTo(visioShape1.get_CellsU("PinY-Height*0.5"));

方法2：使用形状内置连接点 #

Visio默认矩形的四个侧边中点已预设连接点，可直接通过visRowConnectionPts行索引定位：

• 下边中点：行号0
• 左边中点：行号1
• 右边中点：行号2
• 上边中点：行号3

修改后的代码示例：

// Drop Shape
Visio.Master visioMaster = visioStencil.Masters.get_ItemU(@"Rectangle");
Visio.Shape visioShape = visioPage.Drop(visioMaster, 0.0, 0.0);

Visio.Master visioMaster1 = visioStencil.Masters.get_ItemU(@"Rectangle");
Visio.Shape visioShape1 = visioPage.Drop(visioMaster1, 0.0, 1.0);

// Add a dynamic connector to the page using glue.
Visio.Shape vsoConnectorShape = visioShape.ContainingPage.Drop(app.ConnectorToolDataObject, 0.0, 0.0);

// Set the connector properties, using different arrows, colors, and patterns for many-to-many relationships.

// 连接起点到第一个矩形的上边中点（内置连接点行号3）
Visio.Cell cellBeginX = vsoConnectorShape.get_CellsSRC(1, (short)Visio.VisRowIndices.visRowXForm1D, (short)Visio.VisCellIndices.vis1DBeginX);
cellBeginX.GlueTo(visioShape.get_CellsSRC(3, (short)Visio.VisRowIndices.visRowConnectionPts, (short)Visio.VisCellIndices.visCnnctPtX));
Visio.Cell cellBeginY = vsoConnectorShape.get_CellsSRC(1, (short)Visio.VisRowIndices.visRowXForm1D, (short)Visio.VisCellIndices.vis1DBeginY);
cellBeginY.GlueTo(visioShape.get_CellsSRC(3, (short)Visio.VisRowIndices.visRowConnectionPts, (short)Visio.VisCellIndices.visCnnctPtY));

// 连接终点到第二个矩形的下边中点（内置连接点行号0）
Visio.Cell cellEndX = vsoConnectorShape.get_CellsSRC(1, (short)Visio.VisRowIndices.visRowXForm1D, (short)Visio.VisCellIndices.vis1DEndX);
cellEndX.GlueTo(visioShape1.get_CellsSRC(0, (short)Visio.VisRowIndices.visRowConnectionPts, (short)Visio.VisCellIndices.visCnnctPtX));
Visio.Cell cellEndY = vsoConnectorShape.get_CellsSRC(1, (short)Visio.VisRowIndices.visRowXForm1D, (short)Visio.VisCellIndices.vis1DEndY);
cellEndY.GlueTo(visioShape1.get_CellsSRC(0, (short)Visio.VisRowIndices.visRowConnectionPts, (short)Visio.VisCellIndices.visCnnctPtY));

两种方法对比 #

• 方法1更灵活，支持自定义任意形状的侧边中点计算；
• 方法2更简洁，依托Visio内置连接点，适配标准矩形场景。
