Using Custom tools in WebViewer 2.0

[Matt Parizeau]

Q:

In WebViewer 1.8 I had a custom tool that worked fine. When I upgraded to WebViewer 2.0 it doesn't seem to work anymore. What are the changes required to make it work with WebViewer 2.0?

A:

If you refer to the custom annotations sample (specifically the diamond.js file) you can compare the differences between defining a tool in 1.8 and 2.0. In 2.0 the value that is set in readerControl.toolModeMap should be an instance of the tool instead of a reference to the tool constructor.

For example in 1.8 it was:

readerControl.toolModeMap['AnnotationCreateCustomDiamond'] = CustomDiamondCreateTool;

In 2.0 it should be:

readerControl.toolModeMap['AnnotationCreateCustomDiamond'] = new CustomDiamondCreateTool(readerControl.docViewer);

In 2.0 you should also call the registerTool function which will allow the tool to have the last colors and properties for the associated annotation remembered when creating a new annotation.
