Question

因此，我们有一个如下的应用程序结构：

enter image description here

在EC_GUI构造函数中的

我初始化glViewer

    private void initGlViewer() {
        /**
         * Viewer.
         */
        glViewer = new GLViewer();
        glViewer.setup();
        centerPanel.add(glViewer.getNewtCanvasAWT());
    }

glViewer实现了GLEventListener，它是以下

    public GLViewer() {

        GLProfile gLProfile = GLProfile.getDefault();

        GLCapabilities gLCapabilities = new GLCapabilities(gLProfile);

        glWindow = GLWindow.create(gLCapabilities);
        /*
         *  We combine NEWT GLWindow inside existing AWT application (the main JFrame) 
         *  by encapsulating the glWindow inside a NewtCanvasAWT canvas.
         */
        newtCanvasAWT = new NewtCanvasAWT(glWindow);
    }

在glViewer.setup（）中我将鼠标，键和glEvent监听器添加到glWindow。

我正在使用com.jogamp.newt.event中的键和鼠标事件。

我的keyListener中的keyPressed事件以：

开头

@Override
    public synchronized void keyPressed(KeyEvent ke) {
        System.out.println("keyPressed " + ke.getKeyCode());

和keyReleased也是。

有时我遇到有关触发的不一致。以组合ctrl + o打开fileChooser为例。

这应该是：

keyPressed 17
List of pressed inputs
ctrl
keyPressed 79
List of pressed inputs
ctrl
o
keyReleased 17
keyReleased 79
2014.10.09, 10:53:49  [INFORMATION]  Open a project ...
2014.10.09, 10:53:49  [INFORMATION]  Opening file chooser for load.
2014.10.09, 10:53:55  [INFORMATION]  User clicked 'cancel' in file chooser dialog.

在这里你可以看到我按下ctrl（17），然后按o（17），它们都被释放并且fileChooser被显示出来。然后我退出，你可以在最后一行看到它。

但有时这就是我得到的：

keyPressed 17
List of pressed inputs
ctrl
keyPressed 79
List of pressed inputs
ctrl
o
keyReleased 17
2014.10.09, 10:57:34  [INFORMATION]  Open a project ...
2014.10.09, 10:57:34  [INFORMATION]  Opening file chooser for load.
2014.10.09, 10:57:35  [INFORMATION]  User clicked 'cancel' in file chooser dialog.
keyPressed 17
List of pressed inputs
ctrl
keyReleased 79
2014.10.09, 10:57:36  [INFORMATION]  Open a project ...
2014.10.09, 10:57:36  [INFORMATION]  Opening file chooser for load.
2014.10.09, 10:57:38  [INFORMATION]  User clicked 'cancel' in file chooser dialog.

我得到了ctrl和o keyPressed，但我错过了一个keyReleased，在这种情况下是o。无论如何fileChooser仍然被打开。在下一次尝试中我再次按ctrl + o但这次我错过了o keyPressed。我也想念ctrl keyReleased。无论如何fileChooser仍然打开。但有时它不会打开，例如：

keyPressed 17
List of pressed inputs
ctrl
keyPressed 79
List of pressed inputs
ctrl
o
keyReleased 17
2014.10.09, 11:08:57  [INFORMATION]  Open a project ...
2014.10.09, 11:08:57  [INFORMATION]  Opening file chooser for load.
2014.10.09, 11:08:58  [INFORMATION]  User clicked 'cancel' in file chooser dialog.
keyPressed 17
List of pressed inputs
ctrl
keyReleased 79
2014.10.09, 11:08:59  [INFORMATION]  Open a project ...
2014.10.09, 11:08:59  [INFORMATION]  Opening file chooser for load.
2014.10.09, 11:09:02  [INFORMATION]  User clicked 'cancel' in file chooser dialog.
keyReleased 79
keyReleased 17
keyReleased 79

我得到ctrl-keyPressed，o-keyPressed，ctrl-keyReleased，没有o-keyReleased，fileChooser打开，然后我关闭它。我再次按下它们，我得到ctrl-keyPressed，没有o-keyPressed，o-keyReleased，没有ctrl-keyReleased，fileChooser打开，然后我再次关闭它。我再次按ctrl + o，我没有得到任何keyPressed，我只是得到一个o-keyReleased，一个ctrl-keyReleased然后另一个o-keyReleased。 FileChooser这次没有打开..

有任何线索吗？

Answer 1

我通过在每个keyPressed / keyReleased事件中检查按下的修饰符，通过KeyEvent.isXDown（）

查询每个X修饰符来解决

JOGL，com.jogamp.newt.event.KeyListener问题
