This article mainly introduces how to add custom information to a single object in the secondary development of te, which has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let's take a look at it.

In the secondary development of te, attribute information can be stored in the vector layer, and the attribute information of a single object can be obtained by clicking on the object in the layer, but a single object in fly can only get the basic attribute information in te, such as a text tag, which can be identified by the name on the information tree of fly, or the text on the text tag, and some other information is basic attributes. In fact, te also provides interfaces to add custom attribute information to these individual objects, and these custom information can be obtained through the developed interface.

These attribute information, when you need to develop, first add to fly, save in fly, and the information can be saved.

The specific implementation method is as follows (C #):

/ / create an object with set_ClientData in it. The keyword and the content contained in it are all in text format.

Var hole = sgworld.Creator.CreateHoleOnTerrain (sgworld.Creator.GeometryCreator.CreateGeometryFromWKT ("POLYGON (6 / 6 / 11 / 11 / 11 / 11 / 11 / 11 / 11 / 11 / 11 / 11 / 6 / 6), string.Empty," Hole on terrain ")

/ / this adds key content information to the object

Hole.set_ClientData ("keywords", "information content")

/ / the information in the content can be extracted through the get function.

Var data = hole.get_ClientData ("keyword")

This method is relatively simple, that is, it needs to be written during the development of the program.

In js, you write in a different way.

/ / directly through the information equal to the keyword in ClientData

Hole.ClientData ("keyword") = "information content"

/ / extract the information from the content through ClientData

Var data = hole.ClientData ("MyData")
