JMenuItem's hotkey (accelerator) alignment

Hi guys,
How to force all JMenuItem's hotkeys (that are menu items accelerators) be aligned to the right equally for all hotkeys?
I am about JMenuItem.setAccelerator(...) - how to force ALL THE hotkeys for a menu to be aligned equally to the right?
Thanks in advance.

JMenuItem text doesn't align properly

Please look at the code below:
import javax.swing.*;
import java.awt.*;
public class TestJMenuItem extends JFrame {
    public TestJMenuItem() {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JMenuBar jmb = new JMenuBar();
        JMenu jm = new JMenu("File");
        JMenuItem jmi = new JMenuItem("New");
        jmi.setMaximumSize(new Dimension(80, 30));
        jmi.setMinimumSize(new Dimension(80, 30));
        jmi.setPreferredSize(new Dimension(80, 30));
        jmi.setHorizontalAlignment(SwingConstants.RIGHT);
        jm.add(jmi);
        jmb.add(jm);
        setJMenuBar(jmb);
        pack();
        setSize(new Dimension(400, 400));
        setVisible(true);
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                TestJMenuItem tjmi = new TestJMenuItem();
}If you click on "File" menu item, the "New" JMenuItem text seems to go out of the menu item's boudaries. As you can see, I've set the alignment to SwingConstants.RIGHTSetting it to SwingConstants.LEFT leaves a lot of gap from the left edge of the menu item. What am I doing wrong here?
Thanks,

JMenuItem icon/Text verticle alignment question

hello,
can some one help with my question:
I got 5 JMenuItems in a JMenu, some JMenuItems have icon, some not, I want to align them with icon and text in a neat format, like those in Sun's Forte IDE's Menu:
but I can only do it like this:
icon1 open..
save As..
icon2 new..
Exit..
(above each line represent a JMenuItem, I need to make "save as" ,"Exit" to in line with "open" and "new" in verticle direction,NOT with the icon)
sb suggest always set an icon for each JMenuItem, set an transparent Icon for alignment those without icons.
but this sounds not so attractive, are there any other ways? thanks a lot.

Create a method to do the icons. One can have one parameter (menu text) and the other could have two parameters (icon name, menu text). Have the one with just one parameter set up a default transparent icon.

JMenu on multi-screen

Hi
I am in a multi-screen environment and i try to put a JMenuBar on each frame in each screen with the good alignment. My problem is that all the JMenu et JMenuItem are well left aligned on the left screen, but they are rigth aligned on the rigth screen.
Could somebody please advise me on how to accomplish that.
Thank you very much.
Here is a sample of my investigation
import java.awt.*;
import javax.swing.*;
public class Sample {
public Sample() {
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] gs = ge.getScreenDevices();
for (int j = 0;j < gs.length;j++) {
JFrame f = new JFrame(gs[j].getDefaultConfiguration());
Rectangle rect = gs[j].getDefaultConfiguration().getBounds();
f.setLocation(10 + rect.x,10 + rect.y);
JMenuBar menuBar = new JMenuBar();
JMenu toto = new JMenu("toto");
toto.add(new JMenuItem("fils � toto et titi"));
menuBar.add(toto);
f.setJMenuBar(menuBar);
f.pack();
f.show();
public static void main(String[] args) {
Sample sample = new Sample();

Applet Menu Focus?

Hi,
I add some JMenus(with some JMenuItems) to a JMenuBar, and add the JMenuBar to a JApplet.
One of the JMenuItems has an accelerator key("control H").
When the applet is shown, the accelerator key doesn't work.
If I press "any" JMenu/JMenuItems by mouse, then the accelerator key works.
With the tests, I guess menus need the focus before they do something.
Then how do menus get the focus when the JApplet is launched?
When the JApplet is created, it calls method "setFocusable(true)", so the JApplet gets the focus,
but how about the menus?
Thanks!
a cup of Java, cheers!
Sha Jiang

I may get something.
The trouble occurs when I run the Applet by Eclipse,
but when I run it with a real browser(e.g. FireFox 2, IE 6), the accelerator keys works well.

How to set JMenu/JMenuItem.accelerator property in Inspector

How do you set an accelerator key through the accelerator
property in the inspector for a JMenu or JMenuItem object? The
list box contains one item, "<none>". Does one have to create
some special keyboard shotcut objects that then will be added to
the list?
Where can one find documentation for the Swing classes, as far
as I can see it's not included?
Thanks.

I know how to do it in the code but it must be possible to do it
from the Inspector since the property is listed there?
Thanks.

JMenuItem whit Accelerator but without text

helo
I want to make JMenuItem whit accelerator but i don`t want text of accelerator on button! Help i dont know how to do that.
I have my own MyJMenuItem I try to redefine paintComponent() method but this did not help.
thanks

You mean on an icon only menu item, or an invisible menu item? You could do control-key combinations with keybindings...

you can always take a mort drastic action by subclassing MenuItem and

But I belive that the first suggestion is faster.

JTable overrides the accelerator on JMenuItem

I have a JFrame which has a JMenu. Some of the menu items have accelerators associated with them. And the JFrame has a JTable. The accelerators are working only when the focus is not in the JTable. But they are not working when the focus is in JTable. For example, when I selected a row in the table and press the accelerator key, it is not working. Can somebody provide me the solution for it?

Here is the code:
public class SwingEventPropagationTest {
     private static final int shortcutKeyAsciiValue = 65; //A
     public static void main(String[] args) {
          final JFrame frame = new JFrame();
          JMenuBar menuBar = new JMenuBar();
          JMenu menu = new JMenu("Edit");
          JMenuItem menuItem = new JMenuItem("Test");
          KeyStroke ctrlAKeyStroke = KeyStroke.getKeyStroke(shortcutKeyAsciiValue, InputEvent.CTRL_MASK);
          menuItem.setAccelerator(ctrlAKeyStroke);
          menuItem.addActionListener(new SelectAllAction());
          menu.add(menuItem);
          menuBar.add(menu);
          frame.setJMenuBar(menuBar);
          final JTable table = new JTable(new NumericTableModel());
          //Remove Keybindings from table
          table.getInputMap().put(ctrlAKeyStroke, "doNothing");
          table.getActionMap().put("doNothing", new DoNothingAction());
          JScrollPane scrollpane = new JScrollPane(table);
          JPanel panel = new JPanel();
          panel.add(new JButton("test"));
          panel.add(scrollpane);
          frame.getContentPane().add(panel);
          frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
          frame.setSize(500,500);
          frame.setVisible(true);

JMenuItem accelerator on JTable

Hi,
I have a popup menu on a JTable. I have this code (executed at JTable show time):
m_oPopupMenu = new JPopupMenu();
JMenuItem oMenuItem = new JMenuItem("upd row");
oMenuItem.addActionListener(new RowMouseAdapter.UpdateRowEvent());
oMenuItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_M,
ActionEvent.CTRL_MASK));
oMenuItem.setMnemonic(KeyEvent.VK_M);
m_oPopupMenu.add(oMenuItem);
I also have a MouseAdapter which correcly show the pop-up menu and items. But accelerator-key doesn't works.
Any idea?
TIA

JTextPane key bindings override JMenuItem accelerators

hi all,
I have a JTextPane subclass, sitting on a JPanel, sitting on a JFrame which has a JMenu attached. One of my menu commands has an accelerator PgDn... I am trying to disable the PgDn default behaviour in the JTextPane so that the keystroke then "falls through" and activates the menu item...
NOTHING WORKS! Using Keymap and InputMap, have tried "remove", have tried setting the action to "none", etc... it is simple enough to stop PgDn default behaviour in JTextPane, and if I looked into it I could probably explicitly put the action of the menu item in the action map of the JTextPane... but I want to cancel the key binding so that the system looks elsewhere and finds the JMenuItem accelerator...! is this too much to ask??
I am a big user of hotkeys in apps and I want to understand more about all this stuff... how come there are no fewer than 4 generations of InputMap associated with a single JTextPane, for example?
Thanks
Mike

Hi,
Thanks for this... very useful clue... In fact JTextPane itself does handle the PgDn key binding, causing the insertion point to move to the end of the multiline text.
But I followed your suggestion, finding that it is, perhaps unsurprisingly, the vertical Jscrollbar which (otherwise) handles PgDn, causing a scroll down... and a little experimenting finds that this scrollbar is created not on the fly, but once for each JScrollPane...
So I also remove the vertical JScrollBar's key binding for "PgDn" (listing the bindings before and after removal) and... it STILL refuses to work!
So I thought: aha, maybe by some anomaly you have a PgDn binding in the horizontal scrollbar... turns out it seems to share the same input map (actually the parent of the JScrollBar's getInputMap()) as the vertical scrollbar... so no, this doesn't work either!
I also checked out scrollpane's viewport... 0 keys in getInputMap() and the latter does not have parent...
Your suggestion looks like a very promising avenue... somewhere there is something trapping this key, but what? NB when a JButton, for example, is placed on the JPanel, and focus is on the button, PgDn activates the JMenuItem accelerator as expected, so it's obviously sthg to do with the complexity of having a JScrollPane combination
Anything else you can suggest? I really don't want to have to explicitly put an action in the JTextPane... I like to understand, and I like elegant solutions...
Thanks,
Mike

Can't get panes to re-size with hotkeys

I have a small annoyance whereby sometimes my hotkeys to re-size existing panes doesn't work. I had changed the hotkeys to move from pane to pane to be Alt-Left (arrow) and Alt-Right (arrow) key. After looking at the default settings by running tmux's in-pane help (the hotkey shift-?) I commented those two keys out thinking that would reset tmux to its default behaviour. It hasn't worked so far and I'm not sure where else to look aside from my .tmux.conf file. It's based on Thayer's own config:
#~/.tmux.conf - tmux terminal multiplexer config
# Based heavily on Thayer Williams' (http://cinderwick.ca)
## Environmental Options
# Enable tmux to use a 256 colour terminal
# Provided the underlying terminal supports 256 colours, it is usually sufficient to add the following to ~/.tmux.conf:
set -g default-terminal "screen-256color"
set -g terminal-overrides 'xterm*:smcup@:rmcup@'
# If you SSH into a host in a tmux window, you'll notice the window title of your terminal emulator remains to be user@localhost
# rather than user@server. To allow the title bar to adapt to whatever host you connect to, set the following in ~/.tmux.conf
set -g set-titles on
set -g set-titles-string "#T"
# open a man page in new window
bind m command-prompt "split-window 'exec man %%'"
## By default, all windows in a session are constrained to the size of the
## smallest client connected to that session, even if both clients are
## looking at different windows. It seems that in this particular case, Screen
## has the better default where a window is only constrained in size if a
## smaller client is actively looking at it. This behaviour can be fixed by
## setting tmux's aggressive-resize option.
setw -g aggressive-resize on
# mouse-select-pane [on | off]
# # If on, tmux captures the mouse and when a window is
# # split into multiple panes the mouse may be used to
# # select the current pane. The mouse click is also
# # passed through to the application as normal.
set -g mouse-select-pane on
## Upon starting to use tmux, I noticed that I had to add a noticeable delay
## between two characters in a command sequence for it to recognize the
## command, for example between the C-a and n in C-a n. This is because tmux is
## waiting for an escape sequence. Fix that by setting escape time to zero.
set -s escape-time 0

In the Motion tab... right click the video in the sequence and send to viewer...
Then under the MOTION tab... twirl down the DISTORT triangle and then check the aspect ratio there... set either to 0, 33 or -33.
Good luck,

Firefox hotkeys do not function correctly or at all when first loading a page. What is going on?

When i open a video in youtube the hotkeys do not function until i switch to another tab and then back again. Also i can't use the kotkeys to change the volume at all while i am tabbed into firefox.

JMenuItem question?

You can set an accelerator for a JMenuItem like this:
menuItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_C, ActionEvent.CTRL_MASK));Which sets the accelerator to Ctrl + C.
My question is, how do you make Ctrl + Shift + C or F5 to become accelerators?

have you tried combining them with "or"?
menuItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_C,
ActionEvent.CTRL_MASK | ActionEvent.SHIFT_MASK));Edited by: Encephalopathic on Jun 2, 2008 2:25 PM

JTabbedPane w/ Accelerator Keys

I need to add accelerator keys to the tabs of a JTabbedPane, much like the accelerators in a JMenuItem (i.e. under-score for Alt-F, or CTRL-X, etc...).
Any suggestions?
Thanks!

It doesn't support accelerator, but it does support mnemonics. Check out the API for more information.
