Update on ThresholdAdjuster.java

Dear all (probably mostly Wayne)

Under the following link:

http://punias.free.fr/ImageJ/ThresholdAdjuster.java

I have put a modified version of the ThresholdAdjuster.java file where I
added MouseWheelListener features to the minSlider and maxSlider.

The reason why I did this, is that it is sometimes quite difficult to
concentrate (at least for a starting to be old man like I very unfortunately
do) on the picture threshold actions while simultaneously playing with the
sliders via mouse button actions.

With this new code, you just click once on a given slider (minSlider or
maxSlider) and then just forget it by only using the mouse wheel to increase
or decrease its value and thus just concentrate on the given threshold
changes within the given picture.

Im also thinking to add as well the left/right arrow keys for making the
same actions but would first like to get your opinion on this.

Besides that, I have another question (but maybe it is very stupid) about
the thresholder window (while Im working on it).

Indeed why is there a Set window for setting the Lower and Upper Threshold
Level?

Wouldnt it be better or easier to simply transform the indicator values
next to the minSlider or maxSlider to TextFields where the user could then
just simply write the new wished values? (and if there is no objections on
this I will write the needed code)

Looking forward for your comments and/or critics on all this I wish you a
nice day (I hope as well sunny for you).

My best regards,

Philippe

These modifications are in the latest ImageJ daily build (1.51r13).

Arrow key support is a good idea, especially on Macs, where scrollbars are missing buttons for incrementing/decrementing by one.

It would probably be better to display the min and max values in editable text fields.

Re: Update on ThresholdAdjuster.java

Dear Wayne,
I thank you very much for your update, but in the same time I'm a little bit sorry since your update very probably crossed further updates I finalized yesterday evening.
Indeed, on the update you can now find under the same following link:
http://punias.free.fr/ImageJ/ThresholdAdjuster.java
I finalized all the wishes I had described within my previous mail.
This means that I replaced the min/max threshold values labels by editable TextFields which new values can now be validated once the user hits the enter key. And given this new feature, the "Set" button isn't needed anymore and I got thus rid of it.
Besides that, the left/right keys decrease/increase the threshold values in the case the cursor is within one of these editable TextFields.
And small detail, I set the name of these TextFields to minLabel and maxLabel which seemed more consistent than the previous label1 and label2.
I already tested this new code against a couple old macro codes and send it as well to three collegues in my laboratory for debugging and din't find any issues. But maybe there are issues i didn't think about.
Thus if you or somebody within this list finds some bugs within these updates, please inform me abut them.
Have a nice week-end,
Philippe

Hi Philippe,

These updates, which work well, are in the latest ImageJ daily build (1.51r15).

Re: Update on ThresholdAdjuster.java

Hi,

These are very nice improvements. As they would be very useful there (and
would help maintaining a coherent GUI), could they be ported to the B&C
(brightness and contrast) settings window? The mousewheel listener could
also be useful in other settings window such as the gamma window.

Thanks,

Christophe

Re: Update on ThresholdAdjuster.java

Dear Christophe,
Your point is absolutely correct and in the meanwhile I thought as well about it.
I would even push it further since similar updates could as well be applied to most Process->Filters tools making them more user friendly to use. But in the same time such updates are raising questions which I think the community should answer.
Indeed let's take as example the Process->Filters->Gaussian_Blur... tool.
Of how much should the increase/decrease value be? Of 1 pixel? Of 0.1 Pixel?
Should then such increment value be a variable parameter that could be set within a Edit->Options feature?
Also for the B&C (brightness and contrast) settings window (which is probably one of the most used by people) a similar update raises the question on how to deal with the "Unsigned 16-bit range" and "Propagate to all other open pictures" options which are found within the "set" option.
Can these two options simply be integrated within the main window or may this raise some issues?
If such updates are making no harm (i.e. may not break already existing macro or other languages code) and find the agreement of people here, I can move forward to work on them to submit them to Wayne.
My best regards,
Philippe

Re: Update on ThresholdAdjuster.java

In reply to this post by lechristophe

Dear Wayne,
I have already made the code implementing the mouse wheel listener on all the 4 sliders of the B&C window.
And to push further the implementation, I thought about inspiring (I mean from the form) from the Threshold window with a bigger plot and the labels next to the sliders.
But I completely agree with you that we should rather wait until other users are interested by such updates before pushing things further on other tools (given especially that up to now this topic was mostly only a discussion between you and me).
Nevertheless, for the Process>Filters tools having preview options you could as well add me within the people interested by either mouse wheel and/or left/right arrows features additions.
Kindest regards,
Philippe

You should probably wait to see if there is user demand for this. It is not obvious how useful these updates would be with the commands in the Process>Filters menu.

It would probably be best, and easiest, to just keep the “Set” button.
