Multiple key-bound Action
Lets say I have a Navigation action
class NavigationAction extends AbstractAction {
static final String START = "START";
static final String BACK = "BACK";
static final String FORWARD = "FORWARD";
static final String END = "END";
public void actionPerformed(ActionEvent e) {
String cmd = e.getActionCommand();
if (cmd.equals(START)) {
navigationStart();
} else if (cmd.equals(BACK)) {
navigationBack();
} else if (cmd.equals(FORWARD)) {
navigationForward();
} else if (cmd.equals(END)) {
navigationEnd();
}This single action is set to 4 buttons. Each button has a one of the NavigationAction static fields as action command and actual method call is distinguished with command string.
That is all fine.
BUT,
Now i want to assign arrow keys to each for navigation. All I can do is
navigationAction.putValue(Action.ACTION_COMMAND_KEY, NavigationAction.FORWARD);and this way I can have a single action class respond to ONLY ONE key binding.
Is there any way to use multiple keybindings with single action? This would mean adding command string to inputMap for a specific JComponent, but is not supported now.
Any other options?
A simple answer to this question is to use getActionCommand() from the source of the event which is a JButton (with the correct action command) instead of ActionEvent#getActionCommand(). Like this:
class NavigationAction extends AbstractAction {
static final String START = "START";
static final String BACK = "BACK";
static final String FORWARD = "FORWARD";
static final String END = "END";
public void actionPerformed(ActionEvent e) {
String cmd = "none";
if (e.getSource() instanceof JButton) {
cmd = ((JButton)e.getSource()).getActionCommand();
if (cmd.equals(START)) {
navigationStart();
} else if (cmd.equals(BACK)) {
navigationBack();
} else if (cmd.equals(FORWARD)) {
navigationForward();
} else if (cmd.equals(END)) {
navigationEnd();
}

How do you register multiple key presses at the same time?
Hi. I'm trying to write a first person game in OpenGL and I'm having some trouble with key listening. Right now I just use the basic AWT KeyListener. The problem that arises is that whenever I hold down a key, such as a movement key, there is a short pause after it moves me in the appropriate direction, and only after the pause does it start continuously moving me. In addition to that, I can't press multiple keys at once to get diagonal movement (I use WASD for movement). Is there something I can do with AWT to fix both of these problems, or is there something other than AWT that I should use that would be better?
the pause is the typomatic rate of the keyboard, you can avoid that by using the keyPressed and setting a flag then a sleep(myDelayTime).... if they keyRelease--and clearing of the flag--hasn't happened after the sleep, then you're key is still down so keep firing, moving, or what ever.

How to get Multiple Key Combinations
Hi,
I am trying to get the event for multiple key combinations, ie some thing like "*Ctrl + I + M*" or "*Alt + A + S + D*".
For two key combinations ( like Ctrl+I or Ctrl+M) i am able to get, but for more than two keys combinations, can someone give an idea how to get it.
I tried with both KeyCodeCombination and KeyCharacterCombination.
Below is a quick example to check for the key combination demo.
import javafx.application.Application;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.input.KeyCharacterCombination;
import javafx.scene.input.KeyCode;
import javafx.scene.input.KeyCodeCombination;
import javafx.scene.input.KeyCombination;
import javafx.scene.input.KeyEvent;
import javafx.scene.layout.StackPane;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
public class KeyCombinationDemo extends Application {
Stage stage;
Scene scene;
StackPane root;
public static void main(String[] args) {
Application.launch(args);
@Override
public void start(Stage stage) throws Exception {
this.stage = stage;
root = new StackPane();
root.getChildren().add(new Label("Enter any Key"));
this.scene = new Scene(root, Color.LINEN);
stage.setTitle(this.getClass().getSimpleName());
stage.setWidth(600);
stage.setHeight(600);
stage.setScene(this.scene);
stage.show();
final KeyCombination keyComb1=new KeyCodeCombination(KeyCode.I,KeyCombination.CONTROL_DOWN);
final KeyCharacterCombination keyComb2 = new KeyCharacterCombination("M",KeyCombination.CONTROL_DOWN);
this.scene.addEventHandler(KeyEvent.KEY_RELEASED, new EventHandler<KeyEvent>() {
@Override
public void handle(KeyEvent event) {
if(keyComb1.match(event)){
System.out.println("Ctrl+I pressed");
}else if(keyComb2.match(event)){
System.out.println("Ctrl+M pressed");
}Thanks in Advance.
Regards,
Sai Pradeep Dandem.Hi John,
Thanks for the prompt response.
I tried the way you suggested and it worked well !! Thanks :)
But, still i am expecting a direct way to handle this. :p
Anyway here is code which i modified accordingly
final String keyCombination1 = "_ALT_E_O";
final String keyCombination2 = "_ALT_E_P";
final String keyCombination3 = "_CONTROL_H";
final StringBuilder key = new StringBuilder();
this.scene.addEventHandler(KeyEvent.KEY_PRESSED, new EventHandler<KeyEvent>() {
@Override
public void handle(KeyEvent event) {
String codeStr = event.getCode().toString();
if(!key.toString().endsWith("_"+codeStr)){
key.append("_"+codeStr);
this.scene.addEventHandler(KeyEvent.KEY_RELEASED, new EventHandler<KeyEvent>() {
@Override
public void handle(KeyEvent event) {
if(key.length()>0){
if(key.toString().equals(keyCombination1)){
System.out.println("Key Combination 1 pressed");
}else if(key.toString().equals(keyCombination2)){
System.out.println("Key Combination 2 pressed");
}else if(key.toString().equals(keyCombination3)){
System.out.println("Key Combination 3 pressed");
key.setLength(0);
});Thanks & Regards,

Multiple key level associations
Hi,
I am getting the below error during the consistency check.
Table, X, has multiple key level associations.
Can anyone please let me know the reason for the same.
Also, when I drag the physical tables from the physical layer to the BMM Layer, there are some default primary keys in the Logical Table.What considerations does OBIEE take into when deciding upon the Primary Key in the Logical table.
Thanks in Advance
Akshatha"can you check the keys foreign keys for those table "
You didn't mention what I should be checking for.
However, I think I've worked it out now.
I have a dimension table that is referenced by both other dimension tables and the fact tables. Therefore, when imported into BI, both the dimension tables and the fact tables have foreign keys to this common dimension table.
I'm guessing that the foreign keys on the dimension tables are not required - because there are foreign key references from the fact tables to the common table anyway. Bearing in mind that this is a star schema and not a snowflake schema.
=> I deleted all the foreign keys from all my dimension tables, and now the consistency check works ok. -
BPC for Excel: Are multiple key ranges really possible?
Hi Experts,
in a training document I found to possibility of multiple key ranges, to make an input schedule sheet more attractive or insert rows with excel formulas etc.
For example: ColKeyRange: EVRNG(H13:J13;M13:O13)
RowKeyRange: EVRNG(G15:G20;L15:L20)
In my case I want the balance sheet separated. On the left side asset positions, on the right side liability positions (in columns for bot: Previous Year | Actual | Plan
If I define my input schedule like that it gets messed up. No figures, weird formatting etc. Have you implemented an input schedule with multiple key ranges and did it work ok?
Thank you,
CoraHi Cora,
Yes, multiple key ranges do work, but it is a bit complicated as Dzmitry suggests. Your example row expansion will not work, as the row expansion needs to remain in the same columns for each part of the expansion. (In other words, EVRNG(G15:G20;L15:L20) is wrong but EVRNG(G15:G20;G25:G30) is ok.) To achieve your result, Dzmitry is correct that you will probably need to use two EVDREs.
That said, multiple expansions work as follows:
If you are not using an expansion, or you use NOEXPAND in your columns or rows, you can use a multiple key range for formatting purposes and simply hardcode in the members that you wish to see in each key range.
If you want to see different expansions in each key range, then you need to use a special expansion syntax. To take your example, say you have a single dimension in your column with column range defined EVRNG(H13:J13;M13:O13). You could have your column expansion on the category dimension be "PRIORYR,ACTUAL,PLAN|PLAN,ACTUAL,PRIORYR", giving you the same set of categories reversed in each column.

Thinkpad keyboard problem - some keys generate multiple keys when pressed
thinkpad keyboard problem - some keys generate multiple keys when pressed
For example, "t" generates "tr", "y" generates "yu", "backspace" generates "backspace" plus "IBM access connections", "m" generates "mn" and "n" generates "mn". Not all keys are wrong.
For what it's worth, the odd behaviour started shortly after a trip to Miami in which I had a meeting at a cafe in which we were undercover but it was pouring cats and dogs - it was like having a meeting in a sauna - so I am wondering if the high humidity could have caused the behaviour.
I tried replacing the keyboard but the new keyboard has the same problem.
The machine in question is a Thinkpad T23 running Windows XP Pro
Any help would be appreciated as I am now in Los Angeles using a borrowed Mac! :-)i have something along the lines of the same problem.

How to sort on MULTIPLE Keys which are elements of VO's stored in list
How to sort on MULTIPLE Keys which are elements of VO's stored in a list.. without disturbing the ordering done by previous sorting...?
Is there any best soln for the same...
Thanks..How to sort on MULTIPLE Keys which are elements of
VO's stored in a list.. without disturbing the
ordering done by previous sorting...?Do you mean you want to do a heirarchical sort? Where the secondary key is only used when the primary keys are equal etc.? That's pretty trivial. If the primary keys are equal, check the secondary key. How do you sort words in alphabetical order? It's the same process. -
BDB- Recno multiple key/data pairs retrieval
Hey,
I am new to BDB and have just started to work with Berkley DB (ver. 5.3.15) using the Linux C API.
I set up a simple Recno DB which is populated with sequential keys 1,2,3….100. DB Records are in variable length size, although, I am limiting them to a max size.
Below are the environment and DB open flags I am using:
dbenv->open(dbenv, DB_HOME_DIR, DB_SYSTEM_MEM | DB_INIT_LOCK | DB_CREATE | DB_INIT_MPOOL, 0)
dbp->open(dbp, NULL, NULL,DATABASE_NAME, DB_RECNO, DB_CREATE, 0664))
Single record get/put or using cursor to iterate over the all DB works well.
However, I would like to retrieve multiple records in a single get call.
These records can be non-sequential.
For example, retrieving 3 records with the keys 4,89,90. I prefer the bulk buffer to be as minimal as possible (avoiding stack or heap unnecessary memory allocation).
I was reading and saw few examples about using bulk retrieval. Though, I couldn’t find any example for racno bulk get on multiple specified keys.
From what I figured out till now, it seems that I should use:
Get flags: DB_SET_RECNO, DB_MULTIPLE_KEY. And the macros: DB_MULTIPLE_INIT and DB_MULTIPLE_RECNO_NEXT to iterate over a bulk buffer received.
But, I couldn’t figure it out where and how I should specify the list of Keys.
Beside, the BDB man says: "For DB_SET_RECNO to be specified, the underlying database must be of type Btree, and it must have been created with the DB_RECNUM flag."
Does the BDB open with DB_RECNO flag imply that the underlying database is Btree? If creating Btree instead of recno, wouldn’t I loss access performances?
I would appreciate if anyone could supply some guidelines or an example which will assist me to figure it out how to retrieve multiple key/data pairs from a recno DB.
Thanks in advance
KimelI am checking the BDB to see if it can suit my needs (mostly performance wise).
It should work on a simple home router device and should hold router runtime information (static/dynamic).
This information should be accessible for process in the system which can write or read the device info.
The DB is not require to be persistent and is recreated every reboot (memory only).
I believe the DB will hold not more then 200 parameters at max.
DB access rate is around 30 records per sec (write/read)...
Currently, I think of either BDB or maybe just use a normal Linux shared memory (random access + semaphore).
Cons and pros to each...
If I choose BDB, I will use the in memory DB and recno due to access performance considerations.
Getting back to my question, I would like to be able to read a list of parameters in a single get call.
In order to use recno, I will give every parameter a unique id (1 - ip, 2 - subnet , 3 - default gateway).
e.g: ip , subnet , default gateway. (get keys 1,2,3)
Hope you have the relevant info.

Copy & paste multiple key frames?
Is there a way to copy and paste multiple key frames?
Thanks.Drawing a marque around multiple keyframes is easy, too. You can select a property and all of its keyframes will be selected. You can performa sophisticated choices of non-continguous keyframes with command-select. You can also do lots of editing in the graph view.

IsKeyDown - Multiple key detection ?
does anyone know of how to read two keys or check two keys are down/pressed?
I am trying to do a game where the object can mover diagonally so i need the game to react differently if 2 cursor keys are down?
Any ideas about the isKeyDown() function?
The keypressed/ keyreleased function i think will only detect one at a time.
cheers allTry this quick Swing App I knocked up using Sun One. It shows multiple key detection, doesn't mind simultaneous key presses.
I wrote the code for clarity more than anything else.
Run it, see what it does and how it reacts to the cursor keys being pressed.

Combine multiple key figures in single key figure
Hi,
We have a requirement where we need to put multiple key figures into a single key figure
For example source DSO is as follows (+ Unit object):
Region | Date | Amount | Quantity
Asia | 01-01-2008 | 100 | 1000
Eurpoe | 02-02-2008 | 200 | 2000
In Target DSO / Cube, the data must appear like this (no Unit Object)
Region | Date | Type | Value
Asia | 01-01-2008 | Amount | 100
Asia | 01-01-2008 | Quantity | 1000
Eurpoe | 02-02-2008 | Amount | 200
Eurpoe | 02-02-2008 | Quantity | 2000
How do we achieve this?
Regards,
NikhilHi
Write a strart routine that maps Type ->Amount and Quantity,Value -> Kf of Amount or Quantity
Put these chars into Key fields in target DSO = Region | Date | Type ,that will assure unique entries

Model multiple key figures of BI cube to BPC
Hi Experts,Probably a good way of having multiple Key figure values from BI to BPC is to convert it into a account based model (create a dimension and have the key figures as dimension members).I have this scenraio where we are using COPA (costing based) for BPC mgmt consol.This costing based COPA cube in BI has around 120 Key figures.Pls advice on the best way to medel this scnerio in BPC where i would probably need most of those Kf's.I am also looking at how i could reduce separate transformation files/mappings from BI to BPC also on the same..
Many thanks
savvvyHi ,
Thank you Pravin and Ajay for your valuable suggestions and time.what i would like to clarify is on the transformations.Let us say i have my BI cube as costing based itself and this i need to map to BPC dimension.
BI structure- char1 ,char 2,char 3 ,KF1(value field 1),KF2(value field 2),KF3(valuefield3),KF4....
In BPC ,lets say we have a separate dimension (i guess this should be of account type or probably user defined one) which would have dimension members as KF1,KF2,KF3,KF4....
Now how would i do the mapping/transformations from BI to BPC? would i need to have 4different transformation files (assuming i have 4 KF's in my BI cube) for each KF & char combination and thus to load data also many times.
How to achieve modelling side of this situation.any suggestions on this would be greatly appreciated.
many thanks

EVDRE - Multiple Key Ranges - Formatting
I am building a report that uses Multiple Key Ranges, both column and row, as shown below.
ColKeyRange
Sheet1!$N$101:$AA$104,Sheet1!$N$164:$AA$167,Sheet1!$N$213:$AA$216
RowKeyRange
Sheet1!$I$110:$I$160,Sheet1!$I$173:$I$209,Sheet1!$I$222:$I$261
My formatting range has a line with HEADING="GREYBG" in the Criteria column.
However, when I use keywords in my COL Heading area, only the column heading on the first key range is used. For example, if I use a keyword GREYBG in cell N168, it wonu2019t apply to my second data range. The second data range is formatted only from what is in the first column header.
Is this the normal behavior? Is there any way to make the second data range use the formatting from the second column header?Hi,
Did you manage to find an answer to this?
I have tried doing similar, with HEADING="B" and putting B in the column directly to the left of the key, yet it doesn't work on any of the data sets except the first -
Associating multiple key fields.
Is it common practice to associate multiple key fields with a dimension level or fact? For example, if ITEM dimension has two primary key fields (inventory_item_id, sr_instance_id) to identify one single item, PLAN fact table the same, I can't manually associate ITEM dimension or PLAN cube with their tables from Analytic Workspace Manager. But I can do this with OLAP Analytic Workspace Java API. Problem with Java approach is that my AW can't be viewed corrected in AWM.
Is it "right way" to associate multiple key fields? Or should I avoid this (say concatinate keys into one item_key field)?Hi,
