JFileChooser - mnemonics for buttons

Hi,
is it possible to set your own mnemonics for the buttons save/open and cancel in JFileChooser? If so, how does it work??
thanks
sicki

All properties have standard names; I don't know those of the mnemonics and if they're not in the list, I'm afraid you can't change them.
You maybe could try to make our own properties file with a non-existent locale and define what you need in that, if the mnemonics exist and it doesn't work by doing "UIManager.put(propertyname, propertyvalue)". Then you set your Locale before the call to the new Locale and it should work.
Hope this explanation helps you out anyway.
Greetings,
Silkje

JFileChooser's approve button text changes when file

I have a JFileChooser used for loading some XML file(s). We want the approve button's text to be "Load". When I bring up the dialog, the button text initially reads "Load", when I select a directory, it reads "Open", if I select a file again, it goes back to "Load". So far, so good.
The problem comes when using it in a non-English language. When I bring up the dialog, the button text initially reads the appropriately translated "Load". However, when I select a directory, it changes to the English "Open". I do not see a method to use to adjust this text. Am I missing something, or is this a bug?
Any help is greatly appreciated.

Here's some code I'll put into the public domain:
package com.graphbuilder.desktop;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.Stack;
import java.util.Vector;
import java.util.StringTokenizer;
import java.io.File;
<p>Attempt to improve the behaviour of the JFileChooser. Anyone who has used the
the JFileChooser will probably remember that it lacks several useful features.
The following features have been added:
<ul>
<li>Double click to choose a file</li>
<li>Enter key to choose a file after typing the filename</li>
<li>Enter key to change to a different directory after typing the filename</li>
<li>Automatic rescanning of directories</li>
<li>A getSelectedFiles method that returns the correct selected files</li>
<li>Escape key cancels the dialog</li>
<li>Access to common GUI components, such as the OK and Cancel buttons</li>
<li>Removal of the useless Update and Help buttons in Motif L&F</li>
</ul>
<p>There are a lot more features that could be added to make the JFileChooser more
user friendly. For example, a drop-down combo-box as the user is typing the name of
the file, a list of currently visited directories, user specified file filtering, etc.
<p>The look and feels supported are Metal, Window and Motif. Each look and feel
puts the OK and Cancel buttons in different locations and unfortunately the JFileChooser
doesn't provide direct access to them. Thus, for each look-and-feel the buttons must
be found.
<p>The following are known issues: Rescanning doesn't work when in Motif L&F. Some
L&Fs have components that don't become available until the user clicks a button. For
example, the Metal L&F has a JTable but only when viewing in details mode. The double
click to choose a file does not work in details mode. There are probably more unknown
issues, but the changes made so far should make the JFileChooser easier to use.

Type of listener needed for buttons ? please help

hi
does anyone know what type of event or listener one should
include for buttons in a web page which has been downloaded
into a JEditorPane. i have been able to get a web page
onto my JEditorPane and can even follow most of the hyper links
by implemmeting hyperlinklistenter.
but i am not able to do the same for butttons
ie for eg in google web site i am not able to get anythinh
by clicking on button .

This is not easily dooable, You're talking about form submit buttons, which the Default HTMLEditorKit does not support. Even worse, the LinkController class is not overridable, which is a bad design on sun's part.
You'd have to create your own EditorKit, me thinks, and use that for text/html.
Not an easy job, but you could cheat off the HTMLEditorKit source.

How to find function code for buttons on toolbar in oops alv

Hi experts,
I want to remove some buttons from toolbar in oops alv, i know the procedure like get function code and pass the value in a table and pass that table to IT_TOOLBAR_EXCLUDING of
method set_table_for_first_display but I WANT TO KNOW HOW TO FIND FUNCTION CODE FOR BUTTONS ON TOOLBAR IN OOPS ALV

Hi Prakash,
-->First you have to set the pf status in your alv program by,
{FORM pf_status USING rt_extab TYPE slis_t_extab.
SET PF-STATUS 'FIRST'.
ENDFORM.                    "PF_STATUS}
-->Pass this Subroutine name in the Function module, Reuse_alv_grid_display's parameters i.e,
      i_callback_pf_status_set          = 'PF_STATUS'}
*-->Then doble click on that pf status,
From the menu bar, select Extras->Adjust Template->List Viewer,
This will give you the existing statndard gui status of the program*
->Then catch that function codes in the User command Parameter of the Function module Reuse.. i.e,
      i_callback_user_command           = 'COMM'
And make a subroutine of the name 'COMM'i.e,
FORM comm USING ucomm LIKE sy-ucomm selfield TYPE slis_selfield.
DATA: okcode TYPE sy-ucomm.
okcode = ucomm.
CASE okcode.
    WHEN 'REF'.
    CALL FUNCTION 'POPUP_TO_INFORM'
      EXPORTING
        titel         = 'MANSI'
        txt1          = 'CREATED BY'
        txt2          = SY-UNAME
      TXT3          = ' '
      TXT4          = ' '
endcase.
Hope it helps you

Setting icon for buttons in labview 6i

Hi All,
Currently i am working on Labview 6i. i created two buttons in my vi one button is used to perform the test, another will be used to exit from the test. i would like to add icons for those buttons. can anyone tell me how to add icons for buttons.
Thanks,
kalpana

You realize that LabVIEW 6.0 is at least 15 years old? That would be almost equivalent to working with a Windows 98 machine nowadays!
Yes your picture can't be imported in LabVIEW 6.0 on my machine either. I haven't checked about all the details, but the LabVIEW import in 6.0 doesn't seem to work for png and gif images but only for bmp. Newer versions do work for your png file including honoring the transparency at least since version 7.1.

Raster / vector option for buttons

As written in the title, it would be a great improvement to have an option 'raster/vector' for buttons.
The same we already have for MSO and scrolling contents.

Well I figured it out on my own. It was my wacom touch-zoom. My hand brushed it while I had hit both option and command by accident. So it WAS a lock like I thought! Sadly nowhere does anyone seem to MENTION THIS.... so here's the fix;
Option+command+~+e+u+i
Opt and Cmnd are already on lock so you just need to push the others at once. You don't need shift. I just refer to the ~ since it's more specific visually than the ` since it seems to differ depending on font and may look like a typical comma at times.
You can also just swipe the zoom since that's it's function. But in case you get stuck and can't, there it is in normal letters.
The zoom was deactivated and reset with opt+cmnd+8 I managed to find this online which helped me pinpoint the whole problem.
I hope this helps anyone else who's unlucky enough to accidentally trigger such a ridiculous and basically hidden command.

How to set Shortcut keys for button in Apex

Hi
Could anyone help me on how to set shortcut keys for buttons in Apex.
I need to use say ALT + S to submit the page.
The following thread pertaining to HTML DB refered to use ACCESS key. but that couldnt work in my case.
Re: operation of the app. with the keyboard
Any pointers on achieving this would be helpful.
Thanks
Vijay

Hi Vijay,
I’m afraid you must do it using javascript key listener. You can’t use action() on template based buttons because they are actually not HTML buttons but images with hyperlink.
Key listener checks which key has been pressed down and invoke some JS function. For example, write this code in page header:
<script>
document.onkeydown=keyCheck;
function keyCheck(e){
     var KeyId = (window.event) ? event.keyCode : e.keyCode;
     switch(KeyId){
          case 113:
               doSubmit('SAVE');
               break;
          case 118:
               alert('Hello');
               break;
</script>
This script will submit page with request 'SAVE' if you press F2 or will show alert message if you press F7. Modify it to your issue.

Technical names are appearing in OVS pop-up for buttons.

HI Experts,
I have used OVS help in my application, I have deployed and tested it on local WAS where everything works fine.
But, when i access it from portal deployed on staging server, the OVS popup window shows technical names for buttons e.g for Go it shows "view.MainView.gr.c.tc.goSearch.text", same is for Exit button.
Could you please tell me where can be mistake and what are corrective measures?
regards,
abhijeet

Hi,
You will need to open an OSS message for the same under BC-WD-JAV-RUN component. This is an issue with the NW WAS version that you are running. You can find a similar issue [here|OVS - Buttons without correct label].

[svn:fx-trunk] 11602: Fix for Button tooltips.

Revision: 11602
Author:   [email protected]
Date:     2009-11-09 22:35:11 -0800 (Mon, 09 Nov 2009)
Log Message:
Fix for Button tooltips. TextBase dispatches an event when _isTruncated is set through the setIsTruncated() function. This allows ButtonBase to listen for the event and set the tooltip as necessary. If an explicit tooltip is set, then ButtonBase will not set a tooltip.

Condition For Button Display

Hi All,
I have new requirement that create push button to reject all line items in complaint page.
I have done all changes. Now button is functioning as expected.
Issue is button display by default in the initial page even we have not entered any order number in that page. Here i need to set some conditon that if item list is not empty then need to display the button.
Component : ICCMP_BT_BUTTON
View          : ButtonBar
Context Node : BTADMINI
Item List from Another Component & View
Component : ICCMP_BTITEM
View          : ItemList
Context Node : BTADMINI
How can i set condition in HTM page whether Node(BTADMINI) is empty or not. How can i access here.
Note : Button Component as well have Contextnode (BTADMINII).
Hope you got the detailed issue.
Thank you,
Cha

Hi Andreai,
Thank you, as per your suggestion, created bound in "WD_USGE_INITIALIZE" method, initially in this method for Button usage only "BTADMINH" bound was there. Now added BTADMINI as well.
BTADMINI Entity gets populated now. Issue is backend is not updated with the value we are passing from UI.
We have a button in frontend which is used to reject all items of the order.
But if we click the button, item (BTADMINI) entity get filled now, using the entity, calling the execute method with the value of "SetRejectReason" but if we look at the beckend item status still in Open and not "Reject".
Event handle method Code (In Button Component)
lr_entity ?= me->typed_context->btadmini->collection_wrapper->get_current( ).
ls_param-name = 'REASON'. "#EC NOTEXT
ls_param-value = iv_rejection_code.
APPEND ls_param TO lt_param.
lr_entity->execute(
iv_method_name = 'setRejectionReason'
it_param = lt_param ).
Button COMP : ICCMP_BT_Button
Main COMP    : ICCMP_BT_COM ( Which has Item Structure as well, here Button component has been called)
My assumption, BTADMINI instance only might be populatuing without value. Can you please suggest what is the issue
Thank you,
Cha

Custom JDialog, waiting for Button Press

I want to create a custom dialog so i can do the following:
Color yrColor = MyColorChooser().showDialog();
I can create the dialog just fine but i cant get it to return a value
on a button press.
Here is my code:
public class MyColorChooser extends JDialog implements ActionListener{
public MyColorChooser(){
super(Main.Frame, "Color Chooser", true);
// Gui Stuff
public Color showDialog(){
setVisible(true);
// ?? how do i have it wait for button press??
return YourColor;
public void actionPerformed(ActionEvent e) {
if( e.getSource() == Button ){
returnColor()
public void returnColor(){
Color YourColor;
JButton Button = new JButton();
}Im clueless when it comes to JDialogs.
I know i am probably approaching this all wrong.
I need guidance more in the approach rather than the code.
If anyone has any suggestions id appreciate it.
Thank you!

Maybe this simple example can give you some ideas. Note how I make the dialog modal. This will halt the program flow until the dialog is dismissed.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class SimpleTextInputDialog extends JDialog implements ActionListener {
    private JTextField inputField;
    private JButton     okButton;
    private JButton     cancelButton;
    private String      value;
    private SimpleTextInputDialog() {
        setTitle("Enter a value");
        setModal(true);
        inputField = new JTextField(20);
        JPanel textPanel = new JPanel();
        textPanel.add(inputField);
        getContentPane().add(textPanel, BorderLayout.CENTER);
        okButton = new JButton("OK");
        okButton.addActionListener(this);
        cancelButton = new JButton("Cancel");
        cancelButton.addActionListener(this);
        JPanel buttonPanel = new JPanel(
                new FlowLayout(FlowLayout.CENTER, 10, 10));
        buttonPanel.add(okButton);
        buttonPanel.add(cancelButton);
        getContentPane().add(buttonPanel, BorderLayout.SOUTH);
        pack();
        setLocationRelativeTo(null);
    public void actionPerformed(ActionEvent e) {
        if( e.getSource() == okButton ) {
            value = inputField.getText();
        dispose();
    public static String getValue() {
        SimpleTextInputDialog dlg = new SimpleTextInputDialog();
        dlg.setVisible(true);
        return dlg.value;
    public static void main(String[] args) {
        String value = SimpleTextInputDialog.getValue();
        System.out.println("Entered value: " + value);
}And as always, you should study the tutorials:
"How to Make Dialogs":
