New Gantt Editor Release: The Best Ever!

April 5, 2017

It’s been a long time since I last published on this blog, I was very busy on building our  Twproject Project Management Software better and better. We have just released version 6.2 with a new mobile interface… but I’ll be back on this in one of my future posts.

During the last two years we have collected several feedback from our customers, but improvements and fixes were made on the Twproject’s Commercial Gantt editor version only.

The commercial version has been always a step forward the open source one, so after two and half years the gap becomes unbridgeable and I needed time and funds to ferry the open source component to the new world 🙂

Thanks to WikiSuite, that funded the alignment, the new version has finally seen the light.

Twproject’s Free Gantt Editor has been completely redesigned, the look and feel has been improved and usability has been improved.

There is also a lot of work under the hood. In order to fix several “strange” issues on complex Gantt cases, in fact, we have included a sort of unit testing engine (see ganttTestSuite.js) that helped us identifying and fixing issues.

..and some other changes…

We have added new columns on the grid: progress and milestones.

Collapsed tasks’ status is stored as well as the column’s size. Double click on columns will give the best fitting size.

Task delete, indent, outdent, up, down are now available using the keyboard too; that speeds-up the project editing.

Several new permissions have been added to let jQuery Gantt editor working better on real environments.

Last but not least, the Gantt editor works fine with jQuery 3.1.

    Super this new version.
    Thank you for all this work.
    Unless I am mistaken, I have found that if a task lasts 1 day, it can not be enlarged on the fly …

    Can you provide duration entry in decimals. e.g. 10.5 days. Currently it is rounding the duration.

    It is possible to have a javascrip function trigered when the user changes dates on a task?

      not exactly, but
      there is the event “saveRequired.gantt” that is triggered when something changes and the event “addedTask.gantt” when a task is added.

        Many thanks.

        It would be great to have property to get only the changed data, to speed save operations.

        In Safari 10.1, the demo gantt.html seems to have the columns on left panel with some problem on the headers. Columns widths are not the same as rows inside that panel.

    Thank you, this is a great solution. Is there a simple way to modify the application to only use a single resource per task?

      Hi Joe,
      yes, it should be quite easy, check the full editor composition and remove the add button and reduce the number of empty rows.

        Excuse me please. This solved. Its because of jquery.min.js and jquery-ui.min.js which loading with http (in your demo from github). And the browser blocks an unprotected connections.
