Release: 11.12.0, May 14th, 2020


  • Started using system cursors for editing operations in the graphics area. For example
    Cursor.E_RESIZE to change the end time of an activity. “Old” cursors are still there
    and can be enabled by calling RowCanvasBehaviour.useCustomCursors().
  • Added ability to resize a row / change a row height interactively via the row headers.
    This gives the user the same ability for resizing as available in the row headers of
    the tree table.
  • Consolidated license keys for Java 8 and Java 11+ version of FlexGanttFX. The versions
    11.12.x and 8.12.x will now be usable with the same key.
  • Moved the timezone label from the dateline to the timeline, as it was not working
    anymore in combination with a dateline buffer > 0.
  • Removed support for dateline scrolling events. These events could not be produced
    correctly anymore after introducing the dateline buffer concept. Added new “visible
    time interval” read-only property on Timeline, which can be used instead.
  • Enhanced RadarView’s performance. Also added auto-redraw upon activity changes.

Release: 11.11.0, May 2020


Changes / New Features

  • Stopped using PNG icon files. Replaced with Material Design Icons from Ikonli.
  • Added new method to show / hide links. Added new toolbar button to trigger it.
  • Changed default font size used in timeline and dateline.
  • Decreased default height of table header and timeline, now that we use smaller font.
  • Added new “zoom mode” selector to toolbar
  • Added new “show / hide scale / row header” button to toolbar
  • New default value for “show hover interval” is “false”
  • Added new RowHeader concept to replace things like the ScaleLayer. Renamed previous
    RowHeader class to RowHeaderColumn.


  • Fixed bug where grid lines were drawn from previous time unit after zoom operation
  • Fixed bug where calendar entries (e.g. weekend days) were still drawn even when
    currently displayed primary time unit does not want to display them.
  • Fixed bug where too many listeners were added to the timeline when adding and
    removing Gantt chart instances to a multi Gantt chart container.
  • Minimized number of canvas redraws for RowCanvas and LinksCanvas by listing to
    layout pulses from the scene and then drawing instead of immediately drawing all
    the time. Very similar to “requestLayout” calls, that do not immediately lay out
    controls but wait for a good point and time and batch multiple calls to one.
  • Fixed text color used inside the context menu in the upper left corner of the tree
    table (used for showing / hiding columns, etc…).
  • Added missing support for alpha channel / opacity to LinksCanvas / links drawing.

Release: 11.10.0, March 2020

  • Replaced LinksPane with LinksCanvas. Links are now drawn via CanvasAPI (much faster).
  • Replaced ObservableList of ActivityLinks with an IntervalTree for faster lookup.
  • ActivityLink can now carry an optional user object.
  • Custom link renderers can be registered on GraphicsBase.
  • Reworked layout code of DatelineScale to work properly with latest CSS changes in JavaFX.
  • Introduced buffers for RowCanvas and DatelineScale to reduce repaints.

Release: 11.9.1, October 24th, 2019

  • Re-enabled drawing of activity links.
  • Re-added missing API docs / javadocs.

Release: 11.9.0, October 23rd, 2019

  • See Release 8.9.0 plus modularity plus JavaFX 11+ support.
  • The demo folder and the applications inside of it were removed as building standalone
    and executable JAR files have become quite difficult to do with the new module system and
    the fact that JavaFX is now an external dependency.
