Question

因此，我们有一个如下的应用程序结构：

在EC_GUI构造函数中，我初始化了glViewer

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

glViewer实现GLEventListener，如下所示

    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);
    }

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

嗯，有时我会遇到关于触发的不一致。让我们举一个例子，当我按下组合Ctrl+O打开FileChooser时。

这是应该的：

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，您可以看到我按下ctrl(17)，然后o(17)，它们都被释放，并显示fileChooser。然后我退出，你们可以在最后一行中看到。

Answer 1

我通过在每个KeyPressed/KeyReleased事件中检查按下的修饰符，并通过keyEvent.isxDown（）查询每个X修饰符来解决这个问题
