Click the taskbar icon and the window cannot be minimized.

when StageStyle is DECORATED, the window can be minimized.

Can you provide reproducible code of the issue here so that I can look into that?

[hakpaang]

The examples provided by customstage can reproduce this situation.

package v1_0_0;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.stage.Stage;
import lk.vivoxalabs.customstage.CustomStage;
import lk.vivoxalabs.customstage.CustomStageBuilder;

/**

public class StageTest extends Application{

    public static void main(String args[]){
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) throws Exception {

        //Whole usage of CustomStage

        CustomStage stage = new CustomStageBuilder()
                .setWindowTitle("CustomStage example")
                .setWindowColor("rgb(34,54,122)") 
                .build();

        stage.show();

        //Change the scene of the window
        //stage.changeScene(FXMLLoader.load(getClass().getResource("Dashboard.fxml")));
    }
}

I tested this again with JDK8 on windows 10 and I am unable to reproduce this error. Works fine

[Oshan96]

In case, you're using CustomStage-1.3.2 right?

[hakpaang]

java version "1.8.0_202"
CustomStage version "1.3.2"

[hakpaang]

I think it might be a bug in JDK.
All stage styles except StageStyle.DECORATED have this error.

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
import javafx.stage.StageStyle;

public class StageTest extends Application {
  public static void main(String args[]){
    launch(args);
  }

  @Override
  public void start(Stage primaryStage) {
    primaryStage.initStyle(StageStyle.UNDECORATED);  // StageStyle.DECORATED
    Label l = new Label("Hello");
    Scene scene = new Scene(new StackPane(l), 640, 480);
    primaryStage.setScene(scene);
    primaryStage.show();
  }
}

Oh wait. In here, you're not using CustomStage at all! You're just using the original "primaryStage" object. This is not a CustomStage object. Please refer to CustomStage basic usage section in wiki. Read through the wiki and you will understand how to use CustomStage!

Hope this helps. Since this is not a bug, I'm going to close the issue.

I did use CustomStage ,like this

@Override
  public void start(Stage primaryStage) throws IOException {
    CustomStage stage = new CustomStageBuilder()
        .setWindowTitle("CustomStage example")
        .build();
    stage.show();
  }

I mean, the same problem happens with the original undecorated stage.

I couldn't reproduce the bug, but I will look further into this. Also reopening this issue since you've used CustomStage object properly in your code
