如何以编程方式重新路由visio中的连接器？

Question

我正在为visio 2013开发VSTO加载项。我需要重新路由连接器，因为图表很复杂并且包含很多步骤。自动路由连接器没有畅通路径。有没有可用的方法以编程方式重新路由连接器？就像手动在visio应用程序中拖动连接器点一样。

我读了一些vba文件https://docs.microsoft.com/en-us/office/vba/api/visio.connect但没有人给我见解。

你激励我对此采取行动，因为我需要做类似的事情。这是我发现让它发挥作用的一种方式。此子例程引用连接器形状，隐藏自动路由线，添加新几何部分，并手动调整该部分中的多个点（基于原始可见线的百分比高度/宽度）。显然，您可以以编程方式调整数量/位置。

Sub CustomRoutedConnector(shpConnectorShape As Shape)

    With shpConnectorShape
        'Hide the automatically routed connector line (still there, just hidden)
        .CellsSRC(visSectionFirstComponent, 0, 2).FormulaU = "TRUE"

        'Make a custom geometry section
        .AddSection visSectionFirstComponent + 1
        .AddRow visSectionFirstComponent + 1, visRowComponent, visTagComponent
        .AddRow visSectionFirstComponent + 1, visRowVertex, visTagLineTo
        .AddRow visSectionFirstComponent + 1, visRowVertex, visTagMoveTo

        'Set up the new geometry section rows (11,1 and 11,2 are the start and end rows)
        .CellsSRC(11, 0, 0).FormulaForceU = "TRUE"
        .CellsSRC(11, 0, 1).FormulaForceU = "FALSE"
        .CellsSRC(11, 0, 2).FormulaForceU = "FALSE"
        .CellsSRC(11, 0, 3).FormulaForceU = "FALSE"
        .CellsSRC(11, 0, 5).FormulaForceU = "FALSE"
        .CellsSRC(11, 1, 0).FormulaU = "0"
        .CellsSRC(11, 1, 1).FormulaU = "0"
        .CellsSRC(11, 2, 0).FormulaU = "0"
        .CellsSRC(11, 2, 1).FormulaU = "0"

        'Add two additional rows for demonstration (could be programatically 
        'adjusted to however many points you need)

        .AddRow visSectionFirstComponent + 1, 2, visTagLineTo
        .CellsSRC(11, 2, 0).FormulaU = "0"
        .CellsSRC(11, 2, 1).FormulaU = "0"

        .AddRow visSectionFirstComponent + 1, 3, visTagLineTo
        .CellsSRC(11, 3, 0).FormulaU = "0"
        .CellsSRC(11, 3, 1).FormulaU = "0"

        'Adjust the geometry of the rows (the doubles given are percentages of the height/width of the original connector)
        'I recommend stepping through this to see how it moves the points:
        .CellsSRC(visSectionFirstComponent + 1, 2, 0).FormulaU = ".5"
        .CellsSRC(visSectionFirstComponent + 1, 3, 0).FormulaU = ".5"
        .CellsSRC(visSectionFirstComponent + 1, 3, 1).FormulaU = ".5"
        .CellsSRC(visSectionFirstComponent + 1, 4, 0).FormulaU = "1"
        .CellsSRC(visSectionFirstComponent + 1, 4, 1).FormulaU = "1"

    End With

End Sub

此自定义路线的终点仍与开始和结束形状相关联。要完全终止所有自动路由，请使用.LayoutRoutePassive property of the page。 （这可能会给你你想要的东西，但需要一些修改）。
