Cannot get chart data in a Sunburst chart with SELECTED_CHART_DATA

[HanSolo]

Fixed with commit 2c52447

[dmyrdek]

Thanks, but now for me, I can only select a TreeNode once, then you can't select anything again.

[HanSolo]

Can you add some sample code of your problem? Would make things much easier to figure out...

[dmyrdek]

foldersSunburstChart = TileBuilder.create()
         .skinType(Tile.SkinType.SUNBURST)
         .backgroundColor(Color.TRANSPARENT)
         .sunburstBackgroundColor(Color.TRANSPARENT)
         .title("Folder Structure")
         .textVisible(true)
         .titleAlignment(TextAlignment.LEFT)
         .sunburstTextOrientation(SunburstChart.TextOrientation.HORIZONTAL)
         .minSize(400, 480)
         .prefSize(400, 480)
         .sunburstTree(currentUser.getFoldersCountForSunburst())
         .sunburstInteractive(true)
          .build();

foldersSunburstChart.setOnTileEvent((e) -> {
                        if (e.getEventType() == TileEvent.EventType.SELECTED_CHART_DATA) {
                            System.out.println("Clicked on folder " + e.getData().getName());
                            addFilter(e.getData().getName(), false, true, false, false, false);
                        }
                    });
masonryPane.getChildren().add(foldersSunburstChart);

It only knows I click on a Tree Node if I click immediately after you're "check 1 check 2" prints. If I click our wait a second it doesn't register any onTileEvents.

Well when I use the following code I get all SELECTED_CHART_DATA events when clicking on the sunburst chart...
`
tile = TileBuilder.create().skinType(SkinType.SUNBURST)
.prefSize(400, 400)
.title("SunburstTile")
.textVisible(false)
.sunburstTree(tree)
.sunburstBackgroundColor(Tile.BACKGROUND)
.sunburstTextColor(Tile.BACKGROUND)
.sunburstUseColorFromParent(true)
.sunburstTextOrientation(TextOrientation.TANGENT)
.sunburstAutoTextColor(true)
.sunburstUseChartDataTextColor(true)
.sunburstInteractive(true)
.build();

    tile.setOnTileEvent(e -> {
        System.out.println("TileEvent");
        switch(e.getEventType()) {
            case SELECTED_CHART_DATA: System.out.println(e.getData()); break;
        }
    });

`

I just figured out it's because I start a new thread that extends Task

backgroundSentiment = new BackgroundSentiment();
Thread t2 = new Thread(backgroundSentiment);
backgroundSentiment.setOnSucceeded(evt -> {

});
t2.start();

Not sure why this would prevent me from only being able to click on a Sunburst chart, but all other tiles work?

[HanSolo]

Well the question is why do you access the control from a different thread? UI controls should only be accessed on the FX Apllication Thread in JavaFX. You can use Platform.runLater() to do so or simply make sure you access the controls on the FX Application Thread.

[dmyrdek]

My suspicions were wrong, it has nothing to do with that thread. The creation and interaction of the sunburst chart are all happing in the FX Application thread inside of controllers initialize. There's just a second or two where you can select a tree node then after you can't.

[dmyrdek]

Figure it out actually, this was the culprit running in the same initialize method in the controller.

updateGauge = new Thread(new Runnable() {
                        @Override
                        public void run() {
                            while (true) {
                                try {
                                    Thread.sleep(1000);
                                } catch (InterruptedException e) {
                                    System.out.println("Thread was interrupted");
                                    break;
                                }
                                sentimentGauge.setValue(Email.getOverallSentimentDbl(currentUser.getOverallSentiment()));
                            }
                        }
                    });
updateGauge.start();

Is there a reason why that would break only the Sunburst Chart interactivty, but not a radial chart?

[HanSolo]

Like I said before you habe to modify controls on the FXApplication Thread, this is a mandatory thing on all ui frameworks. So modifying the ui directly from a separate thread is simply wrong.

[dmyrdek]

Sorry to waste your time, this is a group project I didn't write any of that
