valence errors not shown in MarvinView

The following line does not cause valence errors to be highlighted in MarvinView:

Code:

mview_param("valenceErrorVisible", "true");

See picture.

The valenceErrorVisible is a MarvinSketch parameter (not MarvinView). Setting of this parameter in MarvinView applet does not effect to MarvinView.

OK, feature request: Make valenceErrorsVisible a MarvinView parameter, too.

Hi Bob,


We have considered your request.


It does not fit in the concept of MarvinView.


The function of a viewer tool can not be syntax check and error highlighting. Editors serve this function.


So, we have to say to no to this request.

Let me explain how I am using MarvinView in this circumstance, and then maybe you will see why this feature would be useful.





A student submits a mechanism with electron-flow arrows. We calculate the results of the student's electron-flow arrows in each stage and compare them to the compounds the student has drawn in the next stage. If the calculated results do not match the student's compounds, or if the calculated results contain half-integral bonds or valence errors, we show the student an error message. We would like to show the student the calculated results so they can see the meaning of what they drew. If the calculated results include a valence error, we would like that valence error to be highlighted. We don't want to display the calculated results in an Editor window, because we want the student to correct the original response, not the calculated results.





It's not a big deal not to have the feature, but, since you already have the parameter in MarvinSketch, I thought it would be easy for you to add it to MarvinView. Obviously, you would want the default value to be false.

We have reconsidered your requrest.


We will implement this feature but not in Marvin 5.0. It is too late to accept new features in 5.0. (We are fixing bugs in the upcomming release.) We have set the priority of this request to Marvin 5.0.1.

Since Marvin 5.0.1, MarvinView can highlight valence errors optionally.


Just define the "valenceErrorVisibleInView" as "true" to switch on this option.

You guys are the best.
