I'm trying to query a user to select from 4 or more sets of radio buttons where there are 5 buttons in each set (Processing 2+). Where I'm having trouble is taking the array created by selecting from each set of buttons and getting it to fill columns in a matrix where the elements can be queried and the 2D array can be printed and ultimately written as csv or tab txt file.
import controlP5.*;
ControlP5 controlP5;
RadioButton c0;
RadioButton c1;
RadioButton c2;
RadioButton c3;
int cols = 5;
int rows = 4;
int[][] myArray = new int[cols][rows];
void setup() {
size(600,650);
controlP5 = new ControlP5(this);
c0 = controlP5.addRadioButton("ch0",60,60)
.setSize(20,20)
.setItemsPerRow(5)
.setSpacingColumn(50)
.addItem("c03", 1)
.addItem("c04", 2)
.addItem("c05", 3)
.addItem("c0AM", 4)
.addItem("c0AF", 5)
;
c1 = controlP5.addRadioButton("ch1",60,80)
.setSize(20,20)
.setItemsPerRow(5)
.setSpacingColumn(50)
.addItem("c13", 1)
.addItem("c14", 2)
.addItem("c15", 3)
.addItem("c1AM", 4)
.addItem("c1AF", 5)
;
c2 = controlP5.addRadioButton("ch2",60,100)
.setSize(20,20)
.setItemsPerRow(5)
.setSpacingColumn(50)
.addItem("c23", 1)
.addItem("c24", 2)
.addItem("c25", 3)
.addItem("c2AM", 4)
.addItem("c2AF", 5)
;
c3 = controlP5.addRadioButton("ch3",60,120)
.setSize(20,20)
.setItemsPerRow(5)
.setSpacingColumn(50)
.addItem("c33", 1)
.addItem("c34", 2)
.addItem("c35", 3)
.addItem("c3AM", 4)
.addItem("c3AF", 5)
;
}
void draw() {
background(0);
}
void controlEvent(ControlEvent theEvent) {
if(theEvent.isGroup() && theEvent.name().equals("ch0") || theEvent.name().equals("ch0") || theEvent.name().equals("ch2") || theEvent.name().equals("ch3")){
println(theEvent.name());
println(theEvent.arrayValue());
//float t=float(theEvent.arrayValue());
//int[][] = { {float getGroup(),float[] getArrayValue()}, {3,2,1,0}, {3,5,6,1}, {3,8,3,4} };
//int cols = 4;
//int rows = 5;
//int[][] myArray = new int[cols][rows];
// Two nested loops allow us to visit every spot in a 2D array.
// For every column I, visit every row J.
//for (int i = 0; i < cols; i++) {
// for (int j = 0; j < rows; j++) {
//myArray[i][j] = float(theEvent.arrayValue);
}
}
You were mixing different things together. Also you don't need to check whole array and store this information. Just update clicked button. Here is new version of your controlEvent
void controlEvent(ControlEvent theEvent) {
int cols = 4;
int rows = 5;
int[][] myArray = new int[cols][rows];
switch(theEvent.getId()){
case 0:
myArray[0][(int)theEvent.value()-1] = 1;
break;
case 1:
myArray[1][(int)theEvent.value()-1] = 1;
break;
case 2:
myArray[2][(int)theEvent.value()-1] = 1;
break;
case 3:
myArray[3][(int)theEvent.value()-1] = 1;
break;
}
println("==== " + theEvent.getId() + " ===");
println(myArray[theEvent.getId()]);
}
To do this simple switch you need to add ID parameter to all your radio buttons like this:
c3 = controlP5.addRadioButton("ch3", 60, 120)
.setId(3)
.setSize(20, 20)
...
I don't know how exactly you want use this array so my implementation use it as local variable so it will be deleted every time this event is called but this could be avoided by declaring array as global variable and then deleting only updated column.

I have application where there is a dynamic web table, I want to select multiple check box for matching value in one of column.
Refer attached image:
Here is what I've tried so far:
List<WebElement> Rows = s.findElements((By.xpath("//a[text()='Nitesh Kumar']")));
System.out.println("No of rows = "+Rows.size());
int z=Rows.size();
int i =0; for(i=0;i<z;i++)
{
for (int j = 0; j < Rows.size(); j++ )
{
s.findElement(By.xpath("//a[text()='Nitesh Kumar']/../../td[1]")).click();
}
}
Change the xpath to
//table[#id='id of the table']/tbody/*/td[3]/a[text()='Nitesh Kumar')]
to find the elements from the table.
Once the elements are found get the size of the list and use the below xpath to click the check box
//table[#id='id of the table']/tbody/*/td[3]/a[text()='Nitesh Kumar')]../td[1]
The complete code would be something like below.
List<WebElement> Rows = s.findElements((By.xpath("//table[#id='id of the table']/tbody/*/td[3]/a[text()='Nitesh Kumar')]")));
System.out.println("No of rows = "+Rows.size());
int z=Rows.size();
int i =0;
for(i=0;i<z;i++)
{
for (int j = 0; j < Rows.size(); j++ )
{
s.findElement(By.xpath("//table[#id='id of the table']/tbody/*/td[3]/a[text()='Nitesh Kumar')]../td[1]")).click();
}
}
I have a 2D array that absolutely will not return the values I need. I start off with this array:
var userdata:Array = new Array(new Array(1000),new Array(4))
Then I try to set all values to 0, with this:
this.onLoad()
{
for (i = 0; i < 1000; i++)
{
for (j = 0; j < 4; j++)
{
userdata[i][j] = 0
trace(userdata[i][j])
}
}
}
This trace returns 8 0s and then a giant amount of "undefined"s. I can't figure out why this would be. I try something like this as well:
userdata[5][0] = 0
trace(userdata[5][0])
It still returns "undefined". Can anyone help with this?
To understand why you got only 8 "zeros" and many undefined values, let's start by your array declaration :
var userdata:Array = new Array(new Array(1000),new Array(4));
Here you should understand that you have created an array with only 2 cells ( that's why userdata[5][0] is undefined ) : the 1st cell is an array of 1000 elements and the 2nd one is an array of 4 elements, and that's why you can only set 8 items ( 2 x 4 ) : the 4th first items from the 1000 of the the 1st cell + the the 4th first items from the 4 of the 2nd cell.
Let's return to your question, you want create a multidimensional array of 1000 rows and 4 columns. To start, we create an array of 1000 rows (cells) :
var a:Array = [1000]; // you can write it : new Array(1000);
Then, we create 4 columns for every row, and set values like this :
var i:Number, j:Number;
for (i = 0; i < 1000; i++)
{
// create the 4 columns
a[i] = [4]; // you can write it : a[i] = new Array(4);
for (j = 0; j < 4; j++)
{
a[i][j] = 0;
}
}
Then we can verify our array :
trace(a[0][0]); // gives : 0
trace(a[255][2]); // gives : 0
trace(a[255][5]); // gives : undefined, because we have only 4 columns
trace(a[1500][0]); // gives : undefined, because we have only 1000 rows
Hope that can help.
I'm using Silk4J and I have a table which is reported as SapTable in the Locator Spy. From that table, I'm trying to get all the texts of the second column, but it hangs or terminates with an exception. In the following you find the code for my tries. Finally I reached the last row of the table, but it hangs there again.
In all examples I'm using a while loop instead of a for loop, because I want to insert more conditions later.
Try 1: Straight forward (I thought)
SapTable table; // initialized somewhere else
int maxrows = table.getRowCount();
int row = 0;
while (row < maxrows)
{
String text = table.getCell(row, COLUMN).getText();
logger.debug(text);
row++;
}
However, this code prints all visible columns, then hangs.
Try 2: adding a PageDn keypress via Silk
Since try 1 printed only the visible cells, I thought adding a keypress every page could help. That was my code:
SapTable table; // initialized somewhere else
int maxrows = table.getRowCount();
int row = 0;
int visibleRows = table.getVisibleRowCount();
table.setFocus();
while (row < maxrows)
{
String text = table.getCell(row, COLUMN).getText();
logger.debug(text);
row++;
if (row % visibleRows == 0)
window.sendVKey(VKey.PAGE_DOWN);
}
Unfortunately this results in an exception "The virtual key is not enabled".
Try 3: adding a PageDn keypress via AwtRobot
Since the built-in sendVKey method did not work, but pressing the PageDn manually works, I switched to an AwtRobot:
SapTable table; // initialized somewhere else
int maxrows = table.getRowCount();
int row = 0;
int visibleRows = table.getVisibleRowCount();
table.setFocus();
while (row < maxrows)
{
String text = table.getCell(row, COLUMN).getText();
logger.debug(text);
row++;
if (row % visibleRows == 0)
{
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_PAGE_DOWN);
robot.keyRelease(KeyEvent.VK_PAGE_DOWN);
}
}
Pressing the key now works and I can see the table scroll to the next entry. However, my test application still hangs.
Try 4: Resetting the row count
Using the Locator Spy again, I found out that the index of the row is reset to zero, so I mimiced that in my code:
SapTable table; // initialized somewhere else
int maxrows = table.getRowCount();
int row = 0;
int visibleRows = table.getVisibleRowCount();
table.setFocus();
while (row < maxrows)
{
String text = table.getCell(row, COLUMN).getText();
logger.debug(text);
row++;
if (row % visibleRows == 0)
{
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_PAGE_DOWN);
robot.keyRelease(KeyEvent.VK_PAGE_DOWN);
row = 0; // <--
}
}
In this case, it prints the first N (number of visible) items of the list, scrolls to position N+1, prints the name of the first (!) row and then hangs when accessing the item with index 1 (after the reset).
Try 5: Sleeping
With some sleeping, I can reach the end of the table:
SapTable table; // initialized somewhere else
int maxrows = table.getRowCount();
int row = 0;
int visibleRows = table.getVisibleRowCount();
table.setFocus();
while (row < maxrows)
{
String text = table.getCell(row, COLUMN).getText();
logger.debug(text);
row++;
if (row % visibleRows == 0)
{
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_PAGE_DOWN);
robot.keyRelease(KeyEvent.VK_PAGE_DOWN);
row = 0;
Thread.sleep(1000); // <--
}
}
In this case, I get all items in the table. But since I don't know when the table ends, it does another getCell() call, which results in a hang again.
The question
I'm really stuck. I've also looked for other methods like getting the real number of rows in the table (getRowCount() doesn't), but didn't find one yet.
How do I get the real number of rows of a SapTable in Silk4J?
It took some trying - the underlying SAP automation API is not really helpful in this case - but here is how you can make it work:
private List<String> fetchItems() {
SapTable table = desktop.find("sap.Table");
SapVerticalScrollBar scrollBar = table.find("/SapVerticalScrollBar");
// the scrollbar maximum value seems to be a more reliable
// way to get the number of items than getRowCount
int itemCount = scrollBar.getMaximum() + 1;
List<String> items = new ArrayList<String>();
int currentAbsoluteRow = 0;
// the first loop iterates through the table page by page
for (int firstRowInPage = 0;
firstRowInPage < itemCount;
firstRowInPage = scrollToNextPage(firstRowInPage)) {
// this loop goes through the items of the current page
for (int currentRowInPage = 0;
currentRowInPage < table.getVisibleRowCount();
currentRowInPage++) {
if(++currentAbsoluteRow > itemCount) {
// we've read all the available items
return items;
}
SapComponent cell = table.getCell(currentRowInPage, 1);
items.add(cell.getProperty("Text").toString());
}
}
return items;
}
private int scrollToNextPage(int firstRowInPage) {
SapTable table = desktop.find("sap.Table");
SapVerticalScrollBar scrollBar = table.find("/SapVerticalScrollBar");
firstRowInPage += scrollBar.getPageSize();
scrollBar.scrollTo(firstRowInPage);
return firstRowInPage;
}
Some pitfalls that I encountered:
getRowCount() returned a higher count than there was in actual items
getVisibleRowCount() returns the number of items that would fit on the current page, even if not all rows were filled with actual items
The returned cell objects are only valid as long as the cell is on the screen, so you'll need to pull the information you want before you scroll to the next page.
While doing some work for my lab in university
I am creating this function where there is a for loop inside another one.
It is not important to know what the method is used for. I just can't figure out why the program doesn't enter the second for loop. This is the code:
public void worseFit(int[] array){
int tempPosition = -1;
int tempWeight = 101 ;
for (int x = 0; x < (array.length - 1); x++){
if (allCrates.getSize() < 1){
Crate crate = new Crate();
crate.addWeight(array[0]);
allCrates.add(crate);
} else{
for( int i = 1; i < (allCrates.getSize() - 1); i++ ){
Crate element = allCrates.getElement(i);
int weight = element.getTotalWeight();
if (weight < tempWeight){
tempWeight = weight;
tempPosition = i;
Crate crate = new Crate();
if (weight + tempWeight <= 100){
crate.addWeight(weight + tempWeight);
allCrates.setElement(i, crate);
} else {
crate.addWeight(weight);
allCrates.setElement(allCrates.getSize(), crate);
} // if
} // if
} // for
} // if
} // for
} // worseFit
Once the program enters the else part of the code it goes straight
away back to the beginning of the first for loop.
Would anyone know how to solve this problem?
There seems to be some discrepancies with the expected values of allCrates.getSize().
If allCrates.getSize() returns 2, it will go to the second for loop, but not run it, as i < allCrates.getSize() - 1 will result in false
You might want to use <= instead of <
Initialize the variable i in your second loop to 0 instead of 1. Because if your getSize() returns 1 the it will not enter the if part and after entering the else part the for loop condition will evaluate to false and hence your for loop will not be executed.
Can anyone tell me the most efficient/performant method to access 2D seismic data using Ocean?
For example, if I need to perform a calculation using data from 3x2D seismic lines (all with the same geometry) is this the most efficient way?
for (int j = 0; j < seismicLine1.NumSamplesJK.I; j++)
{
ITrace trace1 = seismicLine1.GetTrace(j);
ITrace trace2 = seismicLine2.GetTrace(j);
ITrace trace3 = seismicLine3.GetTrace(j);
for (int k = 0; k < seismicLine1.NumSamplesJK.J; k++)
{
double sum = trace1[k] + trace2[k] + trace3[k];
}
}
Thanks
A followup to #Keith's suggestion - with .NET4 his code could be refactored to a generic:
public static IEnumerable<Tuple<T1, T2, T3>> TuplesFrom<T1,T2,T3>(IEnumerable<T1> s1, IEnumerable<T2> s2, IEnumerable<T3> s3)
{
bool m1, m2, m3; // "more" flags
using (var e1 = s1.GetEnumerator())
using (var e2 = s2.GetEnumerator())
using (var e3 = s3.GetEnumerator())
while ((m1 = e1.MoveNext()) &&
(m2 = e2.MoveNext()) &&
(m3 = e3.MoveNext()))
yield return Tuple.Create(e1.Current, e2.Current, e3.Current);
if (m1 || m2 || m3)
throw new ArgumentException(); // sequences of unequal lengths
}
Which gives:
foreach (var traceTuple in TuplesFrom(seismicLine1.Traces, seismicLine2.Traces, seismicLine3.Traces))
for (int k = 0; k < maxK; ++k)
sum = traceTuple.Item1[k] + traceTuple.Item2[k] + traceTuple.Item3[k];
What you have will work except for the two bugs I see, but it can also be made slightly faster. First the bugs. Your loops should be testing NumSamplesIJK.J not .I for the outer loop and .K, not .J for the inner loop. The .I is always 0 for 2D lines.
You can get a slight performance lift by minimizing the dereference of the NumSamplesIJK properties. Since the geometries are the same you should create a pair of variables for the J and K properties and use them.
int maxJ = seismicLine1.NumSamplesIJK.J;
int maxK = seismicLine1.NumsamplesIJK.K;
for (int j = 0; j < maxJ; j++)
...
for (int k = 0; k < maxK; k++)
...
You might also consider using the Traces enumerator instead of calling GetTrace. It will process the data in trace ascending order. Unfortunatley with three lines the code is a bit harder to read.
int maxK = SeismicLine1.NumSamplesIJK.K;
IEnumerator line2Traces = seismicLine2.Traces.GetEnumerator();
ITrace line2Trace = line2Traces.MoveNext();
IEnumerator line3Traces = seismicLine3.Traces.GetEnumerator();
ITrace line3Trace = line3Traces.MoveNext();
foreach (ITrace line1Trace in seismicLine1.Traces)
{
for (int k = 0; k < maxK; k++)
{
double sum = line1Trace[k] + line2Trace[k] + line3Trace[k];
}
line2Trace = line2Traces.MoveNext();
line3Trace = line3Traces.MoveNext();
}
I don't know what, if any, performance lift this might provide. You'll have to profile it to find out.
Good luck.
