Apache POI PPT (Java) - Updating TextShape keeping text formatting/shape formatting

I am trying to produce several reports (i.e. N PPTX files) based on different inputs/for different users on the same PPTX template I created.
I have several preformatted XSLFTextShape on the PPTX template that contains a single XSLFTextParagraph already formatted (i.e. both the shape and the text). Each shape contains a particular placeholder that I need to substitute with a dynimic value. I have this value in a Map (placeholder,newValue). I am successful in updating the placeholder with the new value using:
textShape.clearText();
XSLFTextRun run = paragraph.addNewTextRun();
run.setText(newText);
So, when I produce the PPTX in output the text is updated but font color, font formatting, font size are changed compared to those I defined in the template. How can I keep the same formatting?
Any solutions to simply change the text while keeping original formatting?
Thanks in advance!

For everybody which may be interested in this topic in the future - I post the solution (working if one TextBox has a single Paragraph). This solution loops on all text boxes and in the case one contain one of the vales specified in the Placeholder->newValue map, it will update it maintaining the formatting.
public static void updateTextBoxesWithDesiredValues(XMLSlideShow ppt, Map<String, String> placeHolderDefinedValue) {
logger.info("ElapsedTime: " + tM.getTimeElapsedReadableFormat() + " ########## Updating single text box content...");
List<XSLFSlide> allSlides = ppt.getSlides();
int updatedElements = 0;
for (XSLFSlide currentSlide : allSlides) {
for (XSLFShape shape : currentSlide.getShapes()) {
if (shape instanceof XSLFTextShape) {
XSLFTextShape textBox = (XSLFTextShape) shape;
String elementTextContent = textBox.getText();
for (Object key : placeHolderDefinedValue.keySet()) {
if (elementTextContent.equals(key)) {
List<XSLFTextParagraph> textBoxParagraphs = textBox.getTextParagraphs();
List<XSLFTextRun> textBoxParagraphTextRuns = textBoxParagraphs.get(0).getTextRuns();
//System.out.println("########################## check paragraph number in textbox: " + textBoxParagraphs.size() + " - TextRuns: " + textBoxParagraphs.get(0).getTextRuns().size());
logger.info("ElapsedTime: " + tM.getTimeElapsedReadableFormat() + updatedElements + ") Updating: " + textBox.getText() + " --> " + placeHolderDefinedValue.get(key));
for (XSLFTextRun r : textBoxParagraphTextRuns) {
r.setText(placeHolderDefinedValue.get(key));
}
updatedElements++;
//break;
}
}
}
}
}
logger.info("ElapsedTime: " + tM.getTimeElapsedReadableFormat() + " Total Text Element Content Updated: " + updatedElements + " #########################");
}

It's kind of horrible - but yeah there's a reason they called it "POI".
Here's my approach to "only reset text" of an existing XSLFTextShape (that must have at least some text pre-set!):
textShape.getTextParagraphs().get(0).getTextRuns().get(0).setText(text);
for (int i = 1; i < textShape.getTextParagraphs().get(0).getTextRuns().size(); i++) {
textShape.getTextParagraphs().get(0).getTextRuns().get(i).setText("");
}
for (int i = 1; i < textShape.getTextParagraphs().size(); i++) {
textShape.getTextParagraphs().get(i).getTextRuns().stream().filter(tr -> !tr.getRawText().equals("\n")).forEach(tr -> tr.setText(""));
}
It will replace all existing text(paragraphs/runs) with "empty" text, but linebreaks can't be replaced for some reason. So this might leave you with some trailing lines - as they usually(!) are transparent this won't really hurt a lot.
.clearText / removing paragraphs either destoyed the formatting for me, or didn't work. Trying to reset the style (fontColor, fontFamily, fontSize, isBold, isItalit, ...) didn't result in satisfying results :(

Editing Items Inside Grid - Using Vaadin 7.7.4

I have grid in my Vaadin project. I need to edit the cell/s by click on the cell. I dont need buffered mode, but I need help with this.
My grid code:
Grid grid = new Grid();
IndexedContainer container = new IndexedContainer();
grid.setContainerDataSource(container);
container.addContainerProperty("March",String.class, "");
container.addContainerProperty("January",String.class, "");
container.addContainerProperty("February",String.class, "");
grid.getColumn("March").setEditable(true);
grid.getColumn("January").setEditable(true);
grid.getColumn("February").setEditable(true);
container.addItem(1);
Item item = container.getItem(1);
item.getItemProperty("March").setValue("01.03.2017");
grid.setSelectionMode(SelectionMode.NONE);
//Here I want have my addItemClickListener
grid.addItemClickListener(event ->
Notification.show("Y: " + event.getPropertyId() + " X: " + event.getItemId()));
I want change the cell "01.03.2017" E.G to "Something else". Or add a new data to the free cells from other Container property. Thanks !

Add grid.setEditorEnabled(true);

Using GeoCharts with GWT application to create map. How do I draw shapes?

Currently I have a GWT 2.8 project. In that project I use Geocharts to draw out maps of the USA. The exact package I use is the following.
com.googlecode.gwt.charts.client.geochart
I was wondering if anyone had any example code that would allow me to draw shapes similar to how it is done here.
https://developers.google.com/maps/documentation/javascript/examples/polygon-simple
The basics of the code I have is the following.
GeoChart chart = new GeoChart();
DataTable dataTable = DataTable.create();
GeoChartOptions options = GeoChartOptions.create();
##add some longitude and latitude points to draw out ###
chart.draw(dataTable, options);
A starting point would be greatly helpful.

the GeoChart from the google-visualization library uses SVG
it is easy to draw and add shapes, once the chart's 'ready' event fires
however, there is no option for drawing shapes similar to the maps api
meaning, you will not be able to set specific lat / lng coordinates for the shape's placement
here is a working snippet that adds a circle and triangle to the chart...
google.charts.load('current', {
callback: drawRegionsMap,
packages: ['geochart']
});
function drawRegionsMap() {
var data = google.visualization.arrayToDataTable([
['Country', 'Popularity'],
['Germany', 200],
['United States', 300],
['Brazil', 400],
['Canada', 500],
['France', 600],
['RU', 700]
]);
var chartDiv = document.getElementById('chart_div');
var chart = new google.visualization.GeoChart(chartDiv);
google.visualization.events.addListener(chart, 'ready', function () {
var svg = chartDiv.getElementsByTagName('svg')[0];
var circle = document.createElementNS('http://www.w3.org/2000/svg', 'circle');
circle.setAttribute('cx', '380');
circle.setAttribute('cy', '80');
circle.setAttribute('r', '72');
circle.setAttribute('stroke', '#000000');
circle.setAttribute('stroke-width', '2');
circle.setAttribute('fill', 'rgba(0,0,255,0.5)');
svg.appendChild(circle);
var poly = document.createElementNS('http://www.w3.org/2000/svg', 'polygon');
poly.setAttribute('points', '50,400 210,400 210,50');
poly.setAttribute('stroke', '#000000');
poly.setAttribute('stroke-width', '2');
poly.setAttribute('fill', 'rgba(255,0,0,0.5)');
svg.appendChild(poly);
});
chart.draw(data);
}

How to deal with datepicker in Appium Android

My android application is using datepicker but i am not able to select date through datepicker. I used following code in application for datepicker but it does not work.
List<WebElement> pick = driver.findElements(By.className("android.widget.EditText"));
pick.get(0).sendKeys("21");
pick.get(1).sendKeys("Mar");
pick.get(2).sendKeys("1989");

Swipe method will help you to scroll calendar dates , Make sure that you have added Java-client JARs to your project then only swipe method will support.
Example :
First click on your calendar icon and then use following code :
Thread.sleep(5000);
for(int y=0;y<3;y++)
{
driver.swipe(350,511,350,577,0);
}
Swipe Syntax :
driver.swipe(startx, starty, endx, endy, duration);
Note : Above in code I have used sample co-ordinates so you change it according to your need. You can get exact co-ordinates from bound values of that date picker.
I have used loop in above code as I want to swipe 3 times , so it is something like if current date is 1st may then it will swipe till 4th may.
you can modify loop as per your need.

I have used Xpath to perform Datepicker action & it is working properly.
driver.findElement(By.xpath("//android.widget.NumberPicker[#index='0']")).sendKeys("Jan");
driver.findElement(By.xpath("//android.widget.NumberPicker[#index='1']")).sendKeys("24");
driver.findElement(By.xpath("//android.widget.NumberPicker[#index='2']")).sendKeys("1987");

For all the user who are still finding the way to select date can use the below code. I am using this code and working perfectly for me. It will work for calendar attached.
do {
WebElement source = driver.findElement(By.xpath("//android.view.View[#instance='0']"));
WebElement destination = driver.findElement(By.xpath("//android.view.View[#instance='22']"));
TouchAction action = new TouchAction((PerformsTouchActions)driver);
System.out.println("Dragging item");
action.longPress(source).moveTo(destination).release().perform();
boolean bul = driver.findElementsByXPath("//android.view.View[#content-desc='24 January 2018']").isEmpty();
} while(bul!=false);
driver.findElementByAccessibilityId("24 January 2018").click();
NOTE: I used drag and drop touch action to scroll and this will scroll uptill given date is not found. I just selected same years previous month date. You can use same touch action to select desired year.

I wanted to do the same thing, but for a "calendar" mode DatePicker instead of the "spinner" mode. This is my solution, which has been working fine for me.
from datetime import datetime
datePickerYearTextViewXpath = "//android.widget.TextView[#resource-id='android:id/date_picker_header_year']"
# initialize your appium driver here
driver = getAppiumDriver()
# define some screen dimensions
screenSize = driver.get_window_size()
halfScreenWidth = screenSize['width'] // 2
halfScreenHeight = screenSize['height'] // 2
def getDatePickerCurrentDate(driver):
yearTextView = driver.find_element_by_xpath(datePickerYearTextViewXpath)
yearString = yearTextView.text
dateTextView = driver.find_element_by_xpath("//android.widget.TextView[#resource-id='android:id/date_picker_header_date']")
dateString = dateTextView.text
fullDateString = '{}, {}'.format(dateString, yearString)
currentDate = datetime.strptime(fullDateString, '%a, %b %d, %Y').date()
return currentDate
def setDatePickerDate(driver, targetDate):
# driver is an appium driver
# targetDate must be a datetime.date, not a datetime
currentDate = getDatePickerCurrentDate(driver)
if targetDate.year != currentDate.year:
yearTextView = driver.find_element_by_xpath(datePickerYearTextViewXpath)
yearTextView.click()
# you may need to adjust the following numbers
# depending on your screen size
swipeAmountPerYear = 49
yearsPerScreen = 8
swipeDuration = 400
yearOffset = targetDate.year - currentDate.year
# if target year is older, swipe up (negative)
swipeDirection = -1 if yearOffset < 0 else 1
swipeVector = yearsPerScreen * swipeAmountPerYear * swipeDirection
while True:
elements = driver.find_elements_by_xpath("//android.widget.TextView[#resource-id='android:id/text1']".format(targetDate.year))
found = False
for element in elements:
if element.text == str(targetDate.year):
element.click()
found = True
break
if found:
break
else:
driver.swipe(halfScreenWidth, halfScreenHeight, halfScreenWidth, halfScreenHeight - swipeVector, swipeDuration)
currentDate = getDatePickerCurrentDate(driver)
if targetDate.month != currentDate.month:
monthOffset = targetDate.month - currentDate.month
prevOrNext = 'prev' if monthOffset < 0 else 'next'
prevOrNextButtonXpath = "//android.widget.ImageButton[#resource-id='android:id/{}']".format(prevOrNext)
for i in range(abs(monthOffset)):
driver.find_element_by_xpath(prevOrNextButtonXpath).click()
targetDateContentDescription = targetDate.strftime('%d %B %Y')
driver.find_element_by_xpath("//android.view.View[#resource-id='android:id/month_view']/android.view.View[#content-desc='{}']".format(targetDateContentDescription)).click()
currentDate = getDatePickerCurrentDate(driver)
if currentDate != targetDate:
raise ValueError('Unable to set date picker({}) to target date({})!'.format(currentDate, targetDate))

Check if this helps
driver.FindElement(By.Id("com.eos.eos_du_su:id/ed_manufdate")).Click();
((AndroidElement)(driver.FindElement(By.XPath("//android.widget.NumberPicker[#index='0']//android.widget.Button[#index=0]")))).Tap(1, 2);
((AndroidElement)(driver.FindElement(By.XPath("//android.widget.NumberPicker[#index='1']//android.widget.Button[#index=0]")))).Tap(1, 2);
((AndroidElement)(driver.FindElement(By.XPath("//android.widget.NumberPicker[#index='2']//android.widget.Button[#index=0]")))).Tap(1, 2);
driver.FindElement(By.Id("android:id/button1")).Click();

How to make some letters in string BOLD

I'm looking for an easy way to make some letters in a label bold.
I have a string like this:
String r = "y = "+output0+" "+output1+"sin(x) "+output2+"cos(x)";
and a label:
Label s = new Label(r);
and I need to make the "y" and "sin(x), cos(x)" bold. I tried using HTML, but it didn't work (maybe i was using it wrong). If I set font for that label, then the whole label is bold (including those outputs) which is not what I need.

You can use html style in JLabels and in some other Java components. If you start your text with <html> and end it with </html>, the html code in your JLabel will be rendered.
This should resolve your issue:
JLabel myLabel = new JLabel();
// The following line is required to make this JLabel's text not bold as JLabel's text is bold be default.
myLabel.setFont(myLabel.getFont().deriveFont(Font.PLAIN));
myLabel.setText("<html><strong>y</strong> = " + output0 + " " + output1 + "<strong>sin(x)</strong> " + output2 + "<strong>cos(x)</strong></html>");

Try using HTML (you have to start the string with <html> and end it with </html>):
new Jlabel("<html>Normal text. <strong>This is bold.</strong></html>")
Explanation! <html> tells Java to render HTML (Hyper Text Markup Language), and <strong> tells HTML that the text inside is of strong importance, normally represented in bold.
