Help with adding callback to cornerstone tool

[sinanmb]

Hi,

I would like to add a callback to the Probe tool in order to display a popup after the click on the viewport, (similar to the dialog modal that shows up for the arrowAnnotate tool). I have created a custom cornerstone tool and am looking for pointers on how to setup the callback to open the dialog modal and prompt the user to select a location/description for the measurement.

Thank you

Where are you running into issues? What have you tried?

The arrowAnnotateTool does its magic here: https://github.com/cornerstonejs/cornerstoneTools/blob/master/src/tools/annotation/ArrowAnnotateTool.js#L240-L277

Note that, in the moveNewHandle callback, we use getTextCallback. If you follow the callback/stack from there, you should be able to see how things chain together to prompt the user for info, we update the measurement data, and "unlock" the tool.

Hi Danny,

Thank you for getting back to me quickly. I have managed to add the callback to the tool. I'm also curious about how to change the tool's marker when hovering over the viewport. Currently the marker is a cross, and I would like to replace it with an arrow. I also would like to display some text data next to the marker.

We support "SVG Cursors"

You could also do something similar to dragProbe:
