ButtonPushed event is triggered twice for wt.ListSelector component.

[slootsjj]

The List Selector push button function is triggered twice. To regenerate the issue, run the following:

comp = wt.ListSelector();
comp.AddSource = 'ButtonPushedFcn';
comp.ButtonPushedFcn = @(s,e) fprintf('Event triggered\n')

Solution to this problem is to recreate the event object again before triggering the 'ButtonPushed' event in method 'onButtonPushed', instead of reusing the event object from the callback function.

@slootsjj , I am usiing the widget in a Matlab app, shoudl I add this in a 'startupFcn(app)' ?
do you have any code snippet to do do?

[slootsjj]

@sylvanoMTL Unfortunately you cannot fix the bug in your startup function. Instead, the code of the widget itself has to be changed. This change is shown in the pull request that solves this issue: #137 . However, it will take some time for this change to take effect.

If you cannot wait for the change, you could consider changing your code locally in your MATLAB environment. To do this, follow the steps below.

Open the ListSelector code by typing the following in your command window:

edit wt.ListSelector

Replace line 414 and 429 from

notify(obj,"ButtonPushed",evt);

to

evtOut = wt.eventdata.ButtonPushedData(evt.Button);
notify(obj,"ButtonPushed",evtOut);

I hope this helps.

I have merged this to master branch and will generate a new release.

@sylvanoMTL you may grab the 2.4.2 draft release from the linked pull request #138 if you install it as an add-on. Otherwise just pull the master branch. I'll publish the release later this week.

@slootsjj thank you for the fix on this!
