标签： javafx rubiks-cube

我从here获得了在javaFX中解决rubik＆x cube的源代码。有一个用于提示用户输入或确认对话框的代码：

Button bSeq = new Button("Sequence");
    bSeq.setOnAction(e -> {
        String response;
        if (moves.getNumMoves() > 0) {
            response = 
                    Dialogs.create()
                    .owner(stage)
                    .title("Warning Dialog")
                    .masthead("Loading a Sequence").lightweight()
                    .message("Add a valid sequence of movements:\n(previous movements will be discarded)")
                    .showTextInput(moves.getSequence());
        } else {
            response = Dialogs.create()
                    .owner(stage)
                    .title("Information Dialog")
                    .masthead("Loading a Sequence").lightweight()
                    .message("Add a valid sequence of movements")
                    .showTextInput();
        }
        System.out.println("r: " + response);
        if (response != null && !response.isEmpty()) {
            rubik.doReset();
            rubik.doSequence(response.trim());
        }
    });

和确认对话框：

Button bSc = new Button("Scramble");
    bSc.setOnAction(e -> {
        if (moves.getNumMoves() > 0) {
            Action response = Dialogs.create()
                    .owner(stage)
                    .title("Warning Dialog")
                    .masthead("Scramble Cube")
                    .message("You will lose all your previous movements. Do you want to continue?")
                    .showConfirm();
            if (response == Dialog.Actions.YES) {
                rubik.doReset();
                doScramble();
            }
        } else {
            doScramble();
        }
    });

但是点击那个bSeq和bSc按钮没有对话框得到提示，我得到的例外是：

如果我删除Diaog.create()并手动输入回复，一切正常。

答案 0 :(得分：1)

您还没有告诉我们您正在使用哪个JDK和ControlsFX版本，但我猜您已经遇到了这个问题。

http://fxexperience.com/2015/08/controlsfx-and-javafx-8u60/

顺便说一下，当前的快照链接现在是

https://oss.sonatype.org/content/repositories/snapshots/org/controlsfx/controlsfx/8.40.11-SNAPSHOT/

您也可以尝试将代码转换为标准JavaFX对话框，这些对话框现在已有一段时间了。
