我将键绑定到Java应用程序中的事件,但是,我遇到了一个非常奇怪的错误,希望大家能帮助我解决。
KeyStroke up = KeyStroke.getKeyStroke("W");
KeyStroke down = KeyStroke.getKeyStroke("S");
KeyStroke right = KeyStroke.getKeyStroke("D");
KeyStroke left = KeyStroke.getKeyStroke("A");
KeyStroke p2_up = KeyStroke.getKeyStroke("UP");
KeyStroke p2_down = KeyStroke.getKeyStroke("DOWN");
KeyStroke p2_left = KeyStroke.getKeyStroke("LEFT");
KeyStroke p2_right = KeyStroke.getKeyStroke("RIGHT");
/*KeyStroke key_1 = KeyStroke.getKeyStroke("1");
KeyStroke key_2 = KeyStroke.getKeyStroke("2");
KeyStroke key_3 = KeyStroke.getKeyStroke("3");
KeyStroke key_4 = KeyStroke.getKeyStroke("4");
KeyStroke key_5 = KeyStroke.getKeyStroke("5");
KeyStroke key_6 = KeyStroke.getKeyStroke("6");
KeyStroke key_7 = KeyStroke.getKeyStroke("7");
KeyStroke key_8 = KeyStroke.getKeyStroke("8");
KeyStroke key_9 = KeyStroke.getKeyStroke("9");
KeyStroke key2_1 = KeyStroke.getKeyStroke("F1");
KeyStroke key2_2 = KeyStroke.getKeyStroke("F2");
KeyStroke key2_3 = KeyStroke.getKeyStroke("F3");
KeyStroke key2_4 = KeyStroke.getKeyStroke("F4");
KeyStroke key2_5 = KeyStroke.getKeyStroke("F5");
KeyStroke key2_6 = KeyStroke.getKeyStroke("F6");
KeyStroke key2_7 = KeyStroke.getKeyStroke("F7");
KeyStroke key2_8 = KeyStroke.getKeyStroke("F8");
KeyStroke key2_9 = KeyStroke.getKeyStroke("F9");*/
InputMap inputMap = content
.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW);
inputMap.put(up, "up");
inputMap.put(down, "down");
inputMap.put(right, "right");
inputMap.put(left, "left");
inputMap.put(p2_up, "up2");
inputMap.put(p2_down, "down2");
inputMap.put(p2_right, "right2");
inputMap.put(p2_left, "left2");
Bindings KbBinds = new Bindings(this.currentBigBox);
content.getActionMap().put("up", KbBinds.moveUp);
content.getActionMap().put("down", KbBinds.moveDown);
content.getActionMap().put("right", KbBinds.moveRight);
content.getActionMap().put("left", KbBinds.moveLeft);
content.getActionMap().put("up2", KbBinds.p2MoveUp);
content.getActionMap().put("down2", KbBinds.p2MoveDown);
content.getActionMap().put("right2", KbBinds.p2MoveRight);
content.getActionMap().put("left2", KbBinds.p2MoveLeft);
基本上,除LEFT / RIGHT外的所有键都被捕获并绑定。如果我更换这个
KeyStroke p2_left = KeyStroke.getKeyStroke("LEFT");
与
KeyStroke p2_left = KeyStroke.getKeyStroke(“ UP”);
在注释掉p2_up时,p2_left可以按预期工作。
有什么线索吗?
最佳答案
我没有否决它,但我会的。原因是您发布的代码中有90%无法提供有关您的问题的信息。我们不知道您如何使用代码或要将绑定添加到哪个组件的上下文...
在进行键绑定时,我使用“上,下,左,右”没有问题。
