Bit of a mystery to me this, but I have a table in libgdx where everything is being positioned in new cells vertically;
I am not using .row() anywhere.
Probably doing something stupid here but I cant see it.
Clues as to what can cause this?
(I'll post the code if needed, but its not that neat, and seeing as I think knowing anything that can cause a newline will help me, it shouldn't necessarily be needed)
edit
Tried to cut the code down to all the bits that happen when an item gets added
Code;
//function that triggers on adding
//SSSNode is a semantic reference for the items details,it just justs made into a label like object
public void addItem(SSSNode itemsnode){
Item newitem = new Item(itemsnode); //Item extends label
allItems.add(newitem);
super.add(newitem).size(60, 30).top().left().fillY().expandY();
//pack();
//super.invalidate();
//super.validate(); (tried doing pack, validate, and none...neither helped)
//update the GUI bar in case the inventory tab isnt there yet
MainExplorationView.usersGUI.setDataVisible(true);
}
The following code is in "usersGUI", which creates and handles the popup called inventory which is whats in the picture and is the table I cant get to behave.
//ensures the interface for the inventory popup is setup and visible
//also refreshes the links
public void setDataVisible(boolean visible){
if (myContents.isVisible!=true){
myContents.isVisible=visible;
refreshlinks();
setupInventory();
}
}
private void refreshlinks() {
super.clearChildren();
super.addActor(backgroundobject);
super.addActor(ME.playersInventory); //re adds the inventory panel table?
int y = 440;
ME.playersInventory.validate(); //revalidated the table (I dumped this almost everywhere in frustration)
//below is not relevant, it updates other items in a onscreen gui
for (InterfaceButton link : allLinks) {
if (link.isVisible==true){
link.setPosition(5,y);
super.addActor(link);
y=y-30;
}
}
backgroundobject.setSize(85, 200);
backgroundobject.setPosition(0,y+20);
}
//ensures inventory is setup once.
public void setupInventory() {
if (setup){
return;
}
Log.info("setupInventory");
ME.playersInventory.setPrefWidth(super.getWidth());
Log.info("width is "+super.getWidth());
ME.playersInventory.setHeight(200);
ME.playersInventory.pack();
float X = myContents.getX();
float Y = myContents.getY()-ME.playersInventory.getHeight();
Log.info("popping up inventory at:"+X+","+Y);
ME.playersInventory.setPosition(X, Y);
super.validate();
setup=true;
}
The full code is also on GitHub;
https://github.com/ThomasWrobel/MeshExplorerGDX
The whole project is a game being made to demo/test and open source distributed semantic database system. The relevant bit is the inventory and the maybe the gui that creates it.
Anyone with good knowledge of LibGDXs workings should I think not need to look any of the code though if theres other things that can tell a table to start a new row. (ie, any layout restrictions that can cause it to happen automatically? )
layout ending the current row was a side effect to make the layout logic simpler. It is now fixed.
Note HorizontalGroup is still a better fit for your use case and has the benefit that you can add/remove actors at any index.
The answer seems to be that layout() causes new rows;

Adherently this is how its supposed to work, despite the docs not saying that.
I want to try a simple task where if i move a object inside the world and then press a button it should go back to its original position , but its not working , below is the code i am using - the file is here - http://www.fastswf.com/yAnIvBs (when i remove the event listener)
with event listener - http://www.fastswf.com/rpYsIt8
////////========================
stop();
var startXPos:Number = level1WorldObj.box1.x;
var startYPos:Number = level1WorldObj.box1.y;
function areaS(e:Event) {
level1WorldObj.box1.y= startYPos;
level1WorldObj.box1.x= startXPos;
level1WorldObj.box1.removeEventListener(Event.ENTER_FRAME, areaS);
}
but1.addEventListener(MouseEvent.CLICK,nClick3);
function nClick3(event:MouseEvent):void{
level1WorldObj.box1.addEventListener(Event.ENTER_FRAME, areaS);
level1WorldObj.box1.y= startYPos;
level1WorldObj.box1.x= startXPos;
}
/////////////////======================
Now i want to be able to do it many time so i kept the variables that detect the initial x, y as global ...
Here you can see how it behaves in debugdraw mode , strangely only the clip moves not the actual body - http://www.fastswf.com/-Ijkta4
Can some one please guide me here ...
Thanks in advance ...

The graphics that you see (box1) aren't related to the physical object behind the scenes - you're currently only moving the graphics not the object itself.
You need to use either SetPosition() or SetTransform() on the b2Body of the object
Edit 07/7
As you're using the Box2D World Construction Kit, I took a look at the source code (available here: https://github.com/jesses/wck). The main class seems to be BodyShape (https://raw.githubusercontent.com/jesses/wck/master/wck/BodyShape.as).
Looking through it, you should be able to access the b2Body directly. If it's null (which is probably the source of the TypeError that you're getting, then you haven't called createBody(), which is what actually takes all of your properties as creates the physical object behind the scenes.
Once you have a b2Body, if you want to position it based on the graphics, there's a function syncTransform() to do just that.
You should turn on debugDraw on your World class to make it easier to see what's going on in the background. NOTE: this needs to be done before calling create()
I was able to find solution to this problem , i found the starting point by using this -
trace(level1WorldObj.box1.b2body.GetPosition().x);
trace(level1WorldObj.box1.b2body.GetPosition().y);
then once i had the position manually i took down the coordinates and used the below code ....
level1WorldObj.box1.b2body.SetTransform(new V2(-2, 2),0 );
Thanks #divillysausages for all the help ...

I see this only in Chrome.
The full error message reads:
"org.openqa.selenium.WebDriverException: Element is not clickable at point (411, 675). Other element would receive the click: ..."
The element that 'would receive the click' is to the side of the element in question, not on top of it and not overlapping it, not moving around the page.
I have tried adding an offset, but that does not work either. The item is on the displayed window without any need for scrolling.
This is caused by following 3 types:
1.The element is not visible to click.
Use Actions or JavascriptExecutor for making it to click.
By Actions:
WebElement element = driver.findElement(By("element_path"));
Actions actions = new Actions(driver);
actions.moveToElement(element).click().perform();
By JavascriptExecutor:
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("scroll(250, 0)"); // if the element is on top.
jse.executeScript("scroll(0, 250)"); // if the element is on bottom.
or
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("arguments[0].scrollIntoView()", Webelement);
Then click on the element.
2.The page is getting refreshed before it is clicking the element.
For this, make the page to wait for few seconds.
3. The element is clickable but there is a spinner/overlay on top of it
The below code will wait until the overlay disppears
By loadingImage = By.id("loading image ID");
WebDriverWait wait = new WebDriverWait(driver, timeOutInSeconds);
wait.until(ExpectedConditions.invisibilityOfElementLocated(loadingImage));
Then click on the element.
You can also use JavaScript click and scrolling would be not required then.
IJavaScriptExecutor ex = (IJavaScriptExecutor)Driver;
ex.ExecuteScript("arguments[0].click();", elementToClick);
There seems to be a bug in chromedriver for that (the problem is that it's marked as won't fix)
--> GitHub Link
(place a bounty on FreedomSponsors perhaps?)
There's a workaround suggested at comment #27.
Maybe it'll work for you-
I had the same issue, tried all offered solutions but they did not work for me.
eventually I used this:
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("var evt = document.createEvent('MouseEvents');" + "evt.initMouseEvent('click',true, true, window, 0, 0, 0, 0, 0, false, false, false, false, 0,null);" + "arguments[0].dispatchEvent(evt);", findElement(element));
Hope this helps
Wow, a lot of answers here, and many good ones.
I hope I'll add something to this from my experience.
Well guys, in my case there was a cookie overlay hiding the element occasionally.
Scrolling to the element also works; but in my humble opinion (for my case, not a panacea for everyone) the simplest solution is just to go full screen (I was running my scripts on a 3/4 of the screen window)! So here we go:
driver.manage().window().maximize();
Hope that helps!
You need to use focus or scroll on that element. You also might have to use explict wait.
WebElement firstbutton= driver.findElement(By.xpath("Your Element"));
Actions actions = new Actions(driver);
actions.moveToElement(element);
actions.perform();
OR
The element is not clickable because of a Spinner/Overlay on top of it:
By loadingImage = By.id("loading image ID");
WebDriverWait wait = new WebDriverWait(driver, timeOutInSeconds);
wait.until(ExpectedConditions.invisibilityOfElementLocated(loadingImage));
OR
Point p= element.getLocation();
Actions actions = new Actions(driver);
actions.moveToElement(element).movebyoffset(p.x,p.y).click().perform();
OR
If still not work use JavascriptExecutor
JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].click();", firstbutton);
I have seen this in the situation when the selenium driven Chrome window was opened too small. The element to be clicked on was out of the viewport and therefore it was failing.
That sounds logical... real user would have to either resize the window or scroll so that it is possible to see the element and in fact click on it.
After instructing the selenium driver to set the window size appropriately this issues went away for me. The webdriver API is decribed here.
I was getting this error when running tests headless with xvfb-run. They were working flawlessly locally. Using chrome, versions of webdriver / chromedriver / chrome / java etc all identical.
The ‘won’t fix’ bug in chromedriver - GitHub Link pointed out by Tony Lâmpada suggested this may be related to what is / isn't visible on the screen.
Help message for xvfb-run shows the following:
-s ARGS --server-args=ARGS arguments (other than server number and
"-nolisten tcp") to pass to the Xvfb server
(default: "-screen 0 640x480x8")
Changing the resolution for xvfb made the error go away:
xvfb-run -s "-screen 0 1280x1024x16" ...
ruby/watir-webdriver/chrome
I use the following trick and seems like it works:
#scroll to myelement
#browser.execute_script "window.scrollTo(#{myelement.element.wd.location[0]},#{myelement.element.wd.location[1]})"
# click myelement
myelement.when_present.fire_event("click")
I, too, wrestled with this problem. Code works fine in FF, fails on Chrome. What I was trying to do was to click a tickbox - if it wasn't in view, I'd scroll to view and then click. Even scrolling into view works in Chrome, only the bottom few pixels of the tickbox wasn't visible so webdriver refused to click on it.
My workaround is this:
WebElement element = _sectorPopup.findElement(...);
((Locatable) element).getCoordinates().inViewPort();
try {
element.click();
} catch (Exception e) {
new Actions(getWebDriver()).sendKeys(Keys.PAGE_DOWN).perform();
element.click();
}
Chrome also has issues with sendKeys, using Actions is sometimes necessary. Obviously, you need to know which direction and how much you need to go so your mileage may vary. But I prefer this to the javascript hack, so I'm posting it here in case someone else will find it useful.
First, try to get the latest Chrome driver and check if it solves the issue.
In my case, it didn't fix the issue. But, the following solution worked for me so far. The following is C# code but you can follow same logic in your specific language. What we do here is,
Step 1: Focus on the element using the Selenium Actions object,
Step 2: Then do a click on the element
Step 3: If there's an exception, then we trigger a javascript "Click" event on the element by executing the javascript script through the Selenium browser driver's "ExecuteScript" method.
You can also skip step 1 and 2 and try only step 3 too. Step 3 would work on it's own but I noticed some strange behavior in one scenario in which step 3, even though it successfully clicked the element, caused unexpected behavior in other parts of my code after clicking the element.
try
{
//Setup the driver and navigate to the web page...
var driver = new ChromeDriver("folder path to the Chrome driver");
driver.Navigate().GoToUrl("UrlToThePage");
//Find the element...
var element = driver.FindElement(By.Id("elementHtmlId"));
//Step 1
new Actions(driver).MoveToElement(element).Perform();
//Step 2
element.Click();
}
catch (Exception)
{
//Step 3
driver.ExecuteScript("document.getElementById('elementHtmlId').click();");
}
I was getting the same issue while running selenium script in python. Here is what I used to click on the element:
from selenium.webdriver.common.action_chains import ActionChains
ActionChains(driver).click(element).perform()
When using Protractor this helped me:
var elm = element(by.css('.your-css-class'));
browser.executeScript("arguments[0].scrollIntoView();", elm.getWebElement());
elm.click();
I made this method based on a comment from Tony Lâmpada's answer. It works very well.
def scroll_to(element)
page.execute_script("window.scrollTo(#{element.native.location.x}, #{element.native.location.y})")
end
Today I got the same kind of issue. You don't believe me if i say how i solved the issue.
By maximizing the browser size
Yes, it is a pointer issue that means the size of the browser. For that, you just need to maximize the window size manually or through the code.
I was facing a similar problem whre i have to check two check boxes one after the other.But i was getting the same above error.hence i added wait in between my steps for checking the checkboxes....its working fine and great.here are the steps:-
When I visit /administrator/user_profiles
And I press xpath link "//*[#id='1']"
Then I should see "Please wait for a moment..."
When I wait for 5 seconds
And I press xpath link "//*[#id='2']"
Then I should see "Please wait for a moment..."
When I visit /administrator/user_profiles_updates
The reason for this error is that the element that you are trying to click is not in the viewport (region seen by the user) of the browser. So the way to overcome this is by scrolling to the desired element first and then performing the click.
Javascript:
async scrollTo (webElement) {
await this.driver.executeScript('arguments[0].scrollIntoView(true)', webElement)
await this.driver.executeScript('window.scrollBy(0,-150)')
}
Java:
public void scrollTo (WebElement e) {
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeAsyncScript('arguments[0].scrollIntoView(true)', e)
js.executeAsyncScript('window.scrollBy(0,-150)')
}
Apparently this is the result of a "Won't Fix" bug in the Chrome driver binary.
One solution that worked for me (Our Mileage May Vary) can be found in this Google Group discussion, Comment #3:
https://groups.google.com/forum/?fromgroups=#!topic/selenium-developer-activity/DsZ5wFN52tc
The relevant portion is right here:
I've since worked around the issue by navigating directly to the href of
the parent anchor of the span.
driver.Navigate().GoToUrl(driver.FindElement(By.Id(embeddedSpanIdToClick)).FindElement(By.XPath("..")).GetAttribute("href"));
In my case, I'm using Python, so once I got the desired element, I simply used
driver.get(ViewElm.get_attribute('href'))
I would expect this to only work, however, if the element you are trying to click on is a link...
Re Tony Lâmpada's answer, comment #27 did indeed solve the problem for me, except that it provided Java code and I needed Python. Here's a Python function that scrolls to the element's position and then clicks it.
def scroll_to_and_click(xpath):
element = TestUtil.driver.find_element_by_xpath(xpath)
TestUtil.driver.execute_script('window.scrollTo(0, ' + str(element.location['y']) + ');')
element.click()
This solved the problem for me in Chrome 34.0. It caused no harm in Firefox 28.0 and IE 11; those browsers aren't subject to the problem, but scrolling to the element's position before clicking it still isn't a bad thing.
This might happen if the element changes position while the driver is attempting to click it (I've seen this with IE too). The driver retains the initial position but by the time it actually gets to clicking on it, that position is no longer pointing to that element. The FireFox driver doesn't have this problem BTW, apparently it "clicks" elements programmatically.
Anyway, this can happen when you use animations or simply change the height of elements dynamically (e.g. $("#foo").height(500)). You need to make sure that you only click elements after their height has "settled". I ended up with code that looks like this (C# bindings):
if (!(driver is FirefoxDriver))
{
new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(
d => d.FindElement(By.Id(someDynamicDiv)).Size.Height > initialSize);
}
In case of an animation or any other factor you can't easily query for, you can utilize a "generic" method that waits for the element to be stationary:
var prevLocation = new Point(Int32.MinValue, Int32.MinValue);
int stationaryCount = 0;
int desiredStationarySamples = 6; //3 seconds in total since the default interval is 500ms
return new WebDriverWait(driver, timeout).Until(d =>
{
var e = driver.FindElement(By.Id(someId));
if (e.Location == prevLocation)
{
stationaryCount++;
return stationaryCount == desiredStationarySamples;
}
prevLocation = e.Location;
stationaryCount = 0;
return false;
});
I met this because a loading dialog cover on this element. I simplely solve it by add a waiting before working with the this element.
try {
Thread.sleep((int) (3000));
} catch (InterruptedException e) {
//
e.printStackTrace();
}
Hope this help!
Explanation of error message:
The error message simply says, that the element you want to click on is present, but it is not visible. It could be covered by something or temporary not visible.
There could be many reasons why the element is not visible in the moment of the test. Please re-analyse your page and find proper solution for your case.
Solution for particular case:
In my case, this error occures, when a tooltip of the screen element i just clicked on, was poping over the element I wanted to click next. Defocus was a solution I needed.
Quick solution how to defocus would be to click to some other element in another part of the screen which does "nothing" resp. nothing happens after a click action.
Proper solution would be to call element.blur() on the element poping the tooltip, which would make the tooltip disapear.
I was facing the same problem with clj-webdriver (clojure port of Selenium). I just translated the previous solution to clojure for convenience. You can call this function before doing click or whatever to avoid that problem.
(defn scrollTo
"Scrolls to the position of the given css selector if found"
[q]
(if (exists? q)
(let [ loc (location-once-visible q) jscript (str "window.scrollTo(" (:x loc) "," (:y loc) ")") ]
(execute-script jscript))))
Maybe it's not really clean solution but it works:
try:
el.click()
except WebDriverException as e:
if 'Element is not clickable at point' in e.msg:
self.browser.execute_script(
'$("{sel}").click()'.format(sel=el_selector)
)
else:
raise
I was getting this bug because I tested a hover and then needed to click on the link underneath the tooltip. The solution was to add page.find('.sp-logo').hover before click_link to get the tooltip out of the way.
It's funny, all the time I spent looking at the various responses, no one had tried the obvious, which of course, I hadn't either. If your page has the same id used multiple times, as mine did, ("newButton",) and the one you want is not the first one found, then you will in all likelihood get this error. The easiest thing to do (C#):
var testIt = driver.FindElements(By.Id("newButton"));
Note it's FindElements, not FindElement.
And then test to see how many results came back from the retrieval. If it's the second one, you can then use:
testit[1].Click();
Or get whomever reused ids to fix them.
After testing all mentioned suggestions, nothing worked. I made this code. It works, but is not beautiful
public void click(WebElement element) {
//https://code.google.com/p/selenium/issues/detail?id=2766 (fix)
while(true){
try{
element.click();
break;
}catch (Throwable e){
try {
Thread.sleep(200);
} catch (InterruptedException e1) {
e1.printStackTrace();
}
}
}
}
public void click(String css) {
//https://code.google.com/p/selenium/issues/detail?id=2766 (fix)
while(true){
try{
driver.findElement(By.cssSelector(css)).click();
break;
}catch (Throwable e){
try {
Thread.sleep(200);
} catch (InterruptedException e1) {
e1.printStackTrace();
}
}
}
}
I do a kind of brute force of clicks and it works for me.
try:
elem.click()
except:
print "failed to click"
size = elem.size
mid_of_y = int(size["height"])/2
stepts_to_do_to_left = int(size["width"])
while stepts_to_do_to_left > 0:
try:
print stepts_to_do_to_left, mid_of_y
action = webdriver.common.action_chains.ActionChains(driver)
action.move_to_element_with_offset(elem, mid_of_y, stepts_to_do_to_left)
action.click()
action.perform()
print "DONE CLICK"
break
except:
pass
If you have jQuery loaded on the page, you can execute the following javascript command:
"$('#" + element_id + "').click()"
Example using python executor:
driver.execute_script("$('#%s').click()" % element_id)
Try to maximize the browser when you are working with resolutions greater than 1024x768.
driver.manage().window().maximize();
I'm trying to create something with a flip effect tutorial from tutplus - http://active.tutsplus.com/tutorials/effects/iphone-page-transition-flash/
However my flip area is much bigger than the tutorial, it's 900px wide. Everything works fine except that it leaves a trail when the width is that big. You'll see it when you flip it a few times.
Someone else posted the same problem in the comments from last year, but no one replied.
Does anyone know a solution to this?
Edit:
Here is a screen shot: http://imageshack.us/f/823/unled2lo.jpg/ (click to enlarge)
The front is purple and the back is white.
As you can see it left a bit of the purple as the page flipped to white.
I couldn't get a screen shot of it turning, but it's even more obvious as the page is actually flipping because the width become narrow which reveals a whole lot more that's left behind on the page.
The tutorial you are using create the flip effect using the build in flash tween classes, they are absolute rubbish, and very slow if you compare to other third part tween classes. That may be causing the trail! Lee Brimelow has a great video tutorial about how to do exact what you need: http://gotoandlearn.com/play.php?id=91 he is using caurina, but I highly recommend you to replace it with tweenLight so far the best tween I ever used.
Ok, thats the walkthrough:
1- Download the files from Lee Brimelow tutorial here http://gotoandlearn.com/files/3dflip.zip
2- Download tweenLight AS3 classes here: http://www.greensock.com/tweenlite/
3- copy the com folder inside greensock-as3 and past it inside 3dflip folder. Now you have all the tween classes you need for your flip!
4- open the flash file 3dflip.fla and replace the original code (located in the first frame) with this:
import com.greensock.TweenLite;
import fl.video.*;
con.visible = false;
var flv:FLVPlayback = con.vid.flvp;
flv.addEventListener(VideoEvent.PLAYING_STATE_ENTERED, onStart);
function onStart(e:Event):void
{
con.visible = true;
loading.visible = false;
}
con.vid.spin.addEventListener(MouseEvent.CLICK, cl);
con.tclip.spin.addEventListener(MouseEvent.CLICK, cl);
var isTurning:Boolean = false;
function cl(e:Event):void
{
if(!isTurning)
{
TweenLite.to(con, 1, {rotationY:con.rotationY+180, onComplete:function(){isTurning=false;}});
isTurning = true;
}
}
addEventListener(Event.ENTER_FRAME, loop);
function loop(e:Event):void
{
if(con.rotationY > 90 && con.rotationY < 270)
con.addChild(con.tclip);
else
con.addChild(con.vid);
if(con.rotationY >= 360) con.rotationY = 0;
}
Thats it. Now publish and see the result. Now all you have to do is replace the video player with the content that you want!
I would check the state of first side - it seems that it's forgotten on stage when "the other side" kicks in.
