Double click to open the hyperlink

By Xiaodong Liang

We have introduced how to add hyperlink in this blog. A further requirement is to open the hyperlink when the user double clicks the object. This will need a couple of APIs:

• InputPlugin to interact with UI for mouse clicking

• A common plugin (say AddInPlugin) to provide a button to invoke InputPlugin

• Call state.GetOverrideURL of COM to get the hyperlinks of the object

The following are a demo code. The plugin EnableToolPluginExample will create a button under Tool Add-ins tab. When the button is clicked, the custom interactive mode is activated. When the user double clicks an object, the first URL will be opened in the default browser.

The complete project is available Download DoubleClick_Hyperlink.
