jmenubar

问题 Is there any way to auto-select a jmenu within my jmenubar when the user's pressing the "ALT" key ? (Like windows softwares) The problem is that the default behavior of my jframe, when the "ALT" key is pressed, is to show up a menu containing the following actions : restore, move, size, reduce, ... What I want my java application to do, is to select my jmenu first item when "alt" is pressed. (Like it would do with a mnemonic : "alt + f") 回答1: Add the action to the ActionMap and InputMap of

问题 I am learning Java Swing and I appended a menuBar to the frame. By default this should call jframe.getContentPane().add(child) . When I ran the script the menuBar didn't show up. But the button was at the very top "y=0" if that makes sense. Then I realized my mistake I actually had to put in a menu in the menubar. Then the menuBar showed up. So that got me thinking...is the "menubar" "contentpane" actually 2 panels? It is confusing the hell out of me. Because that acted a lot like a panel.

问题 I've got a JMenuBar and a JPanel. I'd like to add the JMenuBar to the JPanel. How would I do so? 回答1: You can use a BorderLayout for your JPanel and put the JMenuBar into the NORTH area of the panel with JPanel p = new JPanel(); p.setLayout(new BorderLayout()); p.add(menubar, BorderLayout.NORTH); JMenuBar is a JComponent and can be added to a Container like any other JComponent. 回答2: JMenuBars are set to the JFrame using the setJMenuBar method. See the following tutorial on how to use them.

问题 I've been trying to overload JMenu and put in some custom code to support a JTextField but that isn't going well. My main purpose here is to add a search field to the right of my menu items. So I have something like File, Edit, help on the left and then on the right would be the search bar, almost like how there is a google search bar in some browsers. Does anyone have an idea how I could go about adding this functionality? 回答1: I never see that as JMenuItem , I think that alyways placed in

问题 I wanna create a simple application with Java. I designed the main template in my head but I have a kind of design problem. I am using JMenuBar and JMenu. It works fine but it's location is not exactly what I want. In ubuntu, I use Eclipse and it has menu in titlebar: As you can see , menus are at top.(File,Edit,Source,etc..) However, My application is not the same. Here is my application. JMenu is working fine but in title bar there is no menu. What can I do to create this menus ? Are there

问题 This question is a follow-up to this question. I have a JMenuBar whose behavior is like the menu bars in Firefox and iTunes. That is, the menu bar is initially hidden, but when you press Alt , the menu bar appears. The answer to the other question solved the problem of achieving that functionality, but it brought about another issue: The JMenuItem accelerators are not working when the JMenuBar is not visible. In other words, you must press Alt before CTRL+F (the installed accelerator) will

问题 In the Java Desktop Application template used by Netbeans, a menu bar is created with JMenuBar and JMenuItems. How can I get that bar displayed at the top, where menu bars are displayed in MacOSX instead of in-window, like in Windows? 回答1: Note: This is outdated information - a more recent answer is needed. Java applications look like traditional java applications even under OS X. If you want a native look and feel, there are a few tweaks you have to do. This article series describes them.

问题 On OS X, it makes sense to remove the JMenuBar from your main JFrame and use the screen menu bar instead. I was under the impression that in recent versions of the Apple JDK this is done using the Application.getApplication().setDefaultMenuBar( JMenuBar ); call. When using this, it seems like the accelerator keys are no longer working. The following program illustrates the problem on OS X: import java.awt.*; import java.awt.event.*; import javax.swing.*; import com.apple.eawt.Application;
