如何阅读Shape';的属性
本文关键字:属性 何阅读 Shape | 更新日期: 2023-09-27 17:58:27
我有以下任务。我正在Studio 2010中的C#上为Visio 2010编写一个加载项。假设我打开了一张图表。在这张图中,我有一个任何类型的形状(让我们试着从一开始就管理一个形状)。问题是如何读取此形状的任何属性?我应该使用哪种API?
基本算法:
- 扫描打开的文档中的形状
- 如果文档中有任何形状,那么返回所有形状的数组(或列表)(如果当前文档中没有形状,则返回null)
- 运行shapes数组并读取每个元素的任何属性(如果有机会写入/修改属性,那就太好了)
(代码示例将不胜感激)
我假设通过属性,您指的是Shape Data,它过去在UI中被称为Custom properties,但在API中仍然知道这个名称。
如果您不熟悉ShapeSheet,您应该先在ShapeSheed中查看具有自定义特性的形状,以了解特性是如何定义的。请参阅"形状表发生了什么?"了解如何在Visio 2010中打开形状表。
下面的示例程序应该让您开始学习。本例假设您的电脑上安装了Visio主互操作程序集,并且您的项目中包含了Microsoft.Office.Interop.Visio的引用。
namespace VisioEventsExample
{
using System;
using Microsoft.Office.Interop.Visio;
class Program
{
public static void Main(string[] args)
{
// Open up one of Visio's sample drawings.
Application app = new Application();
Document doc = app.Documents.Open(
@"C:'Program Files'Microsoft Office'Office14'visio content'1033'ASTMGT_U.VST");
// Get the first page in the sample drawing.
Page page = doc.Pages[1];
// Start with the collection of shapes on the page and
// print the properties we find,
printProperties(page.Shapes);
}
/* This function will travel recursively through a collection of
* shapes and print the custom properties in each shape.
*
* The reason I don't simply look at the shapes in Page.Shapes is
* that when you use the Group command the shapes you group become
* child shapes of the group shape and are no longer one of the
* items in Page.Shapes.
*
* This function will not recursive into shapes which have a Master.
* This means that shapes which were created by dropping from stencils
* will have their properties printed but properties of child shapes
* inside them will be ignored. I do this because such properties are
* not typically shown to the user and are often used to implement
* features of the shapes such as data graphics.
*
* An alternative halting condition for the recursion which may be
* sensible for many drawing types would be to stop when you
* find a shape with custom properties.
*/
public static void printProperties(Shapes shapes)
{
// Look at each shape in the collection.
foreach (Shape shape in shapes)
{
// Use this index to look at each row in the properties
// section.
short iRow = (short) VisRowIndices.visRowFirst;
// While there are stil rows to look at.
while (shape.get_CellsSRCExists(
(short) VisSectionIndices.visSectionProp,
iRow,
(short) VisCellIndices.visCustPropsValue,
(short) 0) != 0)
{
// Get the label and value of the current property.
string label = shape.get_CellsSRC(
(short) VisSectionIndices.visSectionProp,
iRow,
(short) VisCellIndices.visCustPropsLabel
).get_ResultStr(VisUnitCodes.visNoCast);
string value = shape.get_CellsSRC(
(short) VisSectionIndices.visSectionProp,
iRow,
(short) VisCellIndices.visCustPropsValue
).get_ResultStr(VisUnitCodes.visNoCast);
// Print the results.
Console.WriteLine(string.Format(
"Shape={0} Label={1} Value={2}",
shape.Name, label, value));
// Move to the next row in the properties section.
iRow++;
}
// Now look at child shapes in the collection.
if (shape.Master == null && shape.Shapes.Count > 0)
printProperties(shape.Shapes);
}
}
}
}
我写了一个库,使更容易
检索多个形状的属性:
var shapes = new[] {s1, s2};
var props = VA.CustomProperties.CustomPropertyHelper.GetCustomProperties(page, shapes);
props中存储的返回值将是一个字典列表。每个字典对应于指定形状的属性。属性的名称是字典中的关键字。
要获取第一个形状的"Foo"属性。。。
props[0]["Foo"]
其检索包含公式&属性的这些方面的结果:
- 日历
- 格式
- 不可见
- 标签
- LangId
- 提示
- 排序键
- 类型
- 价值
- 验证

...
using Visio = Microsoft.Office.Interop.Visio;
namespace RibbonCustomization
{
[ComVisible(true)]
public class Ribbon1 : Office.IRibbonExtensibility
{
public void ReadShapes(Microsoft.Office.Core.IRibbonControl control)
{
ExportElement exportElement;
ArrayList exportElements = new ArrayList();
Visio.Document currentDocument = Globals.ThisAddIn.Application.ActiveDocument;
Visio.Pages Pages = currentDocument.Pages;
Visio.Shapes Shapes;
foreach(Visio.Page Page in Pages)
{
Shapes = Page.Shapes;
foreach (Visio.Shape Shape in Shapes)
{
exportElement = new ExportElement();
exportElement.Name = Shape.Master.NameU;
exportElement.ID = Shape.ID;
exportElement.Text = Shape.Text;
...
// and any other properties you'd like
exportElements.Add(exportElement);
}
}
