[14.4.1] - 2025-03-13

Known Issue

  • This version is not compatible with the VG Pack (any versions):

    • Reason: A VEE Port with this UI Pack and a VG Pack cannot be built:

      [java] microvg/ui-pack:
[java] C:\[...]-configuration\target~\scripts\rip\build\autoConfiguration-microvg.xml:43: VG Pack requires the UI Pack 14.1.0 or higher and the platform fetches the UI Pack ${ui.packVersion}.

    • Workaround: None, use the UI Pack 14.3.3 instead.

MicroUI

Changed

  • Improve the trace events (SystemView description file SYSVIEW_MicroUI.txt is updated).

  • Change some log identifiers to be backward compatible with the UI Pack since version 12.1.5.

FrontPanel

Added

  • Add a button to start/stop the recording of the drawings in the Flush Visualizer.

Changed

  • Improve the content of the tree of the drawing operations in the Flush Visualizer.

  • Show the time between two frames in the Flush Visualizer.

  • Use the core property core.trace.enabled to enable the Flush Visualizer.

  • Do not draw if the clip is empty (align behavior between the simulator and the embedded side).

Fixed

  • Fix the execution of the Front Panel in the HIL classpath (VEE Port with UI and application without UI; since UI Pack 14.3.0).

  • Fix the use of the logs in the mode s3.board.compliant (Use target characteristics).

[14.3.3] - 2025-02-18

FrontPanel

Fixed

[14.3.2] - 2025-02-10

FrontPanel

Fixed

  • Fix the performance issue of LLUIDisplay.convertRegion() when using the Front Panel Framework 1.3.0.

Known Issues

Warning

The following issues concern the UI Packs 14.3.0 and 14.3.2.

Front Panel

  • On non-rectangular displays (see Display Widget), the Front Panel widget display’s filter sometimes disappears partially, causing some visual glitches around the display.

  • The rendering of Front Panel widgets other than the display is truncated: the right and bottom lines (1 pixel thick) are missing. This is caused by the widget rendering clip being too small. As a workaround, you can increase the size of each widget image with empty lines on the right and bottom sides.

  • With a zoom other than 1:1, some Front Panel widgets other than the display may not be rendered, or may be truncated.

Flush Visualizer

  • A native Concurrent Exception may be thrown during application animations. This is due to the drawing storage not being synchronized with the Flush Visualizer text file dump.

  • On non-rectangular displays (see Display Widget), the Front Panel widget display’s filter sometimes disappears partially, causing some visual glitches around the display in the screenshot.

[14.3.0] - 2025-01-24

FrontPanel

Added

  • Add the class ej.fp.widget.display.Rectangle (extracted from ej.tool.frontpanel#widget#4.0.2).

  • Add a statusbar with various information (current zoom, coordinates, etc.).

  • Add the ability to resize and/or scroll the Front Panel.

Changed

  • Speed up the drawing of images whose format is identical to the display, without transparency or transformation.

  • Display a tree of regions and drawings in the Flush Visualizer traces.
