Java 使用场景/舞台作为按钮打开另一个场景/舞台
我在解决这个问题上遇到了困难,我找不到一个正确的答案来解决这个问题。我希望将一个场景/舞台用作打开另一个场景/舞台的按钮,并使用相同的方法调用这两个场景/舞台。以下是完整的方法:Java 使用场景/舞台作为按钮打开另一个场景/舞台,java,javafx,Java,Javafx,我在解决这个问题上遇到了困难,我找不到一个正确的答案来解决这个问题。我希望将一个场景/舞台用作打开另一个场景/舞台的按钮,并使用相同的方法调用这两个场景/舞台。以下是完整的方法: public void createChatWindowMinimized(int agentKey, String message) { LOGGER.enterMethod(); try{ C

我一直在尝试使用CLICK中的鼠标事件,但没有成功,因为实例化另一个窗口的变量(chatController.getChatStage().show())不是最终变量。只需删除当前的声明和chatController的初始化即可:
// ChatAgentsController chatController = null;
在第一个if
语句之前声明并初始化它一次。也就是说,它实际上是最终的,可以在lambda表达式中使用:
boolean controllerExisted = chatAgentsMap.containsKey(agentKey) ;
ChatAgentsController chatController = chatAgentsMap.computeIfAbsent(agentKey, k -> {
LOGGER.message(String.format("Creating chat window for agent '%d'.", k));
return ChatAgentsController.create(this, k, connectedToOpenfireServer, true);
});
if (controllerExisted) {
// chat window has been created
// chatController = chatAgentsMap.get(agentKey);
LOGGER.message(String.format("Showing chat window for agent '%d'.", agentKey));
if(!chatController.getChatStage().isFocused()){
toastStage.show();
chatController.getChatStage().show();
}
} else {
// chatController = ChatAgentsController.create(this, agentKey, connectedToOpenfireServer, true);
toastStage.show();
toastStage.setAlwaysOnTop(true);
//-----Here is where I want that the toastStage or the toastScene is clickable by mouse and that it opens the window already created chatController
toastScene.setOnMouseClicked( e -> chatController.getChatStage().show());
// chatAgentsMap.put(agentKey, chatController);
}
此处:ChatAgentsController chatController=chatAgentsMap.computeIfAbsent(agentKey,k->{LOGGER.message(String.format(“为代理“%d.”创建聊天窗口”),返回ChatAgentsController.create(this,k,connectedToOpenfireServer,true);});它要求放置一个try-catch,但当我这样做时,它仍然显示出一些错误。其中之一就是lambda表达式中的错误返回类型。那么
ChatAgentsController.create(…)
声明了一个选中的异常?将return
语句包装在try
中,并使相应的catch
块记录异常和returnnull
应该可以工作(虽然不一定是最好的)。它工作得很好,非常感谢!你介意给这个问题打分吗?毕竟,我还没有见过很多这样的问题,我知道很多其他人可能会觉得它很有用。
