[英]Closing newly opened JFrame
I'm developing a desktop application using NetBeans IDE. 我正在使用NetBeans IDE开发桌面应用程序。
1) I'm opening a new JFrame after a button click. 1)点击按钮后我打开一个新的JFrame。 While I'm closing any of the opened frames, both are getting closed. 当我关闭任何打开的帧时,两者都被关闭了。
2) And I want to update a new Tabbed JPanel on a JFrame after button click. 2)我想在点击按钮后在JFrame上更新新的Tabbed JPanel。 Thanks in advance. 提前致谢。
Probably you are using the wrong argument. 可能你使用的是错误的论点。 I guess for the JFrames that you want to close without closing the entire application you are doing: 我想对于你要关闭的JFrame而不关闭你正在做的整个应用程序:
jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
While to actually close only the desired frame without closing rest of the frames you need to do: 虽然实际上只关闭了所需的框架而没有关闭其他框架,但您需要这样做:
jFrame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
1) Why did you create lots of Top-Level Containers on Runtime, create only one JFrame and other would be JDialog(Modality) or JWindow(un-decorated), re-use that, 1)为什么你在运行时创建了很多顶级容器 ,只创建了一个JFrame,而另一个是JDialog(模态)或JWindow(未装饰),重用它,
2) really no battery included in my Magic Globe today, for better and sooner hepl you have to post here SSCCE 2)今天我的Magic Globe中真的没有电池,为了更好,更快,你必须在这里发布SSCCE
I want to update a new
JTabbedPane
on aJFrame
after the button click. 我想在单击按钮后在JFrame
上更新新的JTabbedPane
。
You can just update via a reference to the tab's JPanel
and call repaint()
, but sooner or later you should consider the Model–View–Controller pattern. 您可以通过对选项卡的JPanel
的引用进行更新并调用repaint()
,但迟早您应该考虑模型 - 视图 - 控制器模式。
