c# - 如何以编程方式重新路由 visio 中的连接器？

问题描述

我正在为 visio 2013 开发 VSTO 插件。我需要重新路由连接器，因为该图很复杂并且包含很多步骤。自动布线的连接器没有明确的路径。有没有办法以编程方式重新路由连接器？就像在 visio 应用程序中手动拖动连接器点一样。

我阅读了一些 vba 文档 https://docs.microsoft.com/en-us/office/vba/api/visio.connect 但没有一个能让我深入了解。

解决方案

您启发了我对此进行尝试，因为我需要做类似的事情。这是我发现的一种使它起作用的方法。此子例程引用连接器形状，隐藏自动布线的线，添加新的几何部分，并手动调整该部分中的几个点（基于原始可见线的百分比高度/宽度）。您显然可以通过编程方式调整数量/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起点和终点形状相关联。要完全杀死所有自动路由，请使用.LayoutRoutePassive page 的属性。（这可能会给你你正在寻找的东西，但它需要一些修补）。
