Ugly flashing when opening a css-styled stage
Hi,
I'm in the process of evaluating Java FX 8 for our currently
Swing-based product (also Java 8) on OSX.
My first attempt to style a stage's background resulted in an ugly
flashing effect which I would classify as a show-stopper for
delivering a commercial product. This looks like it is caused by the
stage being drawn at least once before the style has been applied, and
I am wondering what the mistake is since my code is more or less a
straight-forward hello world:
package jfxtest;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class JXTest extends Application {
@Override
public void start(Stage primaryStage) throws Exception {
final StackPane pane = new StackPane();
final Button closeButton = new Button("Close");
closeButton.setOnAction(event -> primaryStage.close());
pane.getChildren().add(closeButton);
final Scene scene = new Scene(pane, 800, 600);
scene.getStylesheets().add("dark.css");
scene.getStylesheets();
primaryStage.setScene(scene);
primaryStage.setTitle(getClass().getSimpleName());
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
with dark.css being:
.root {
-fx-background: rgb(54, 54, 54);
}
Is this a Mac-specific problem? Is there a workaround? Which of the
two mailing lists is the more appropriate one to post these things
(JFX problems which look like they might be platform-specific) to?
Thanks,
Robert
Re: Ugly flashing when opening a css-styled stage
I haven't seen this, but here's a hack you can try:
// Show stage transparent once to get proper drawing
_stage.setOpacity(0); _stage.show(); _stage.hide();
_stage.setOpacity(1);
I've done this before to trigger Stage to set it's width/height property (which
I needed to position the stage property).

Re: Ugly flashing when opening a css-styled stage
Thanks but it does not seem to improve the situation.
btw, I am using 1.8.0_05-b13 on Mac OS 10.9.3 on a retina MBP.

Re: Ugly flashing when opening a css-styled stage
To rule out CSS is the reason you could directly set the background:
pane.setBackground(new Background(new BackgroundFill(Color.rgb(54, 54,
54), CornerRadii.EMPTY, Insets.EMPTY)));
Does that improve the situation?

Re: Ugly flashing when opening a css-styled stage
No, it does not. So it is not the CSS.

Hi Robert,
Which of the
two mailing lists is the more appropriate one to post these things
(JFX problems which look like they might be platform-specific) to?
FYI: the JDK Mac OS X Port Project has been completed long time ago, so
currently the macosx-port-dev@ mailing list isn't appropriate for almost
anything.
Please report JavaFX bugs at: https://javafx-jira.kenai.com/
AWT/Swing/JDK bugs can be reported at:
http://bugreport.java.com/bugreport/ (or http://bugs.sun.com/ )
If you wish to participate in the development of the technologies (e.g.
you want to contribute a patch for JavaFX or JDK platform), then you're
welcome to post your suggestions on the appropriate development mailing
lists (openjfx-dev@, awt-dev@, swing-dev@, etc.)

best regards,
Anthony

Oh, that's a surprise.
