Can't find how to change highlightcolor parameter with unfolding

fabwoj

Hi, In a sketch I display map using unfolding. I added countries by following example ChloroplethMapApp. What I can't do is to change the color (by default a big red) of the country selected with my mouse. Please can someone explain how to change the hightlightColor parameter ? Thank you very much.

Hi,

Can someone explain how to use this method : setHighlightColor(int highlightColor) This method would allow me to change the color of a marker selected with the mouse .

I don't understand how this unfolding's method works.

Thank you.

@fabwoj, I'm not personally familiar with unfolding, but it is sometimes difficult for forum members to help you without having more concrete details of your problem. If you can, please post a minimal, complete example sketch (MCVE) showing what you have tried to do with e.g. ChloroplethMapApp, and what is happening instead.

If you have something more concrete to debug perhaps @kfrajer might have a suggestion?

Hi Jeremy, I finally found a complicated way to modify the color and stroke of a selected marker (polygon for me) on my map. I spent many hours to do this but I learned a lot on this library.So... I asked Till Nagel if there was an easy way to do this job. Will see...

Who is kfrajer ?

Thank you
Have a good day !

@fabwoj -- Glad to hear it is working. If you have an example of your custom selection marker solution that might help future users, please share!

@kfrajer is an active forum member who I happened to notice has answered a number of previous unfolding maps forum questions.

Hi, Here is Till 's answer to my problem :

((AbstractMarker) marker).setHighlightColor(color(0, 255, 0,75)); ((AbstractMarker) marker).setHighlightStrokeColor(color(0, 255, 0,75));

It was obsious...pfff

fabwoj

it was obvious not obsious !

@fabwoj What unfolding map version are you using? Are you running processing 2 or 3?

I was checking the example available in unfolding maps (Processing 3.1.2 and Unfolding_for_processing_0.9.8beta) and they use the following call to select the highlight color for markers:

marker.setColor(color(255, 255, 0, transparency));

Here I am using yellow and it worked. Now, my version of ChloroplethMapApp doesn't choose countries using mouse actions.

Hi Kf, The old version of ChloroplethMapApp doesn't choose the countries using mouse actions neither. I was wrong. Sorry. But MarkerSelectionApp does... And if you want to change the highlightcolor you must use : ((AbstractMarker) marker).setHighlightColor(color(0, 255, 0,75));

I'am using Unfolding_for_processing_0.9.6 Till said he fixes this problem. With the next version you should use marker.setHighlightColor(color(0, 255, 0,75));

Have a good day, Fabrice
