I've got a text view and a web view, each inside a scrolled window of their own and I'm trying to achieve synchronized scrolling between the two but I can't seem to get it to work.
The web view is basically taking the text from the text view and rendering it as marked up HTML via webview.load_html_string(). I think the problem could be the delay in loading the HTML as every time the web view is refreshed it is scrolled back to the very start.
Right now I call a function every time the content of the text view is changed and then modify the vadjustment.value of the scrolled window containing the web view.
But this doesn't work. Is it because of the delay? I can't think of any way to solve this issue.
why do you want sync those scrollbars? You can achieve this by using the same Gtk.Adjustment (number of pages sets to 0).
I haven't use much of webkit but it essentialy a widget. so maybe a workaround would be disconnect a signal "value-changed" from Gtk.Adjustment until "load-status" signal from WebKitView reached Webkit.LoadStatus.FINISHED (if that's the correct syntax).
If that doesn't work, maybe you use WebKitView.move_cursor () (if i remember the function properly) based on Gtk.Adjustment on your text view (we use 2 adjustments this time)

In the main page of my website there is a long list, <ul>. Each list item represents a model object. Within the list there are the objects attributes, for example its name etc, and also buttons to change those attributes. The list is loaded from the sqlite database. The issue is since each button changes data in the database, to display the changed data, the view function reloads the page on each button click. That is fine, except the list is very long, and is necessary to scroll down, and on each button click, the page is reloaded therefore goes to the very top of the list. This makes the webpage almost unusable, or at least very annoying to use.
Can someone recommend a workaround to this problem. Please let me know if my question is not clear
It looks like what you want to achieve is something that should be done with Javascript. It will be the simplest way of doing it! For instance, you can call the corresponding API when the user clicks on one of the buttons, and if the API returns 'OK' then you can just update the item with the changes you made (because if the server returned yes, then you can assume that the local version of the data is the same than the one on the server)
As the title says, how can I .click() a button using Selenium, when the button gets "disabled" after using the method clear or send_keys?
Before:
That's the page status when I open it's url... but then right after I run my code to find the textbox and replace it's value, the element gets disabled (maybe by some sort of JS) right after I clear it's content or write something to it using send_keys.
After:
Code:
txt_value = driver.find_element_by_xpath('//input[#id="txtValor4"]')
txt_value.clear() #this disables the button
txt_value.send_keys(str(123,45)) #this also disables the button
My question is:
How can I bypass this website protection and press the Continuar button?
I thought about disabling JS, but the whole website relies on it to produces the requires documents.. wrong alternative.
So I thought about using the button properties to simulate the pressing of the button... just don't know if it's possible, or how I could do this.
Another option was blocking only the JS that disables the button maybe mapping where the command comes from using the inspect element and network tools...
So is there any way to achieve this?
ps.: I can't give the URL because it requires my login data.
Ok, so you can't directly do this through normal means. Selenium WebDriver is made to simulate real use of a browser. It may be possible however to use the execute_script function. (Java Selenium has a built in JavascriptExecutor class, I assume this is python's version.) The execute_script function allows Selenium to perform tasks that a human interacting with a browser can't do.
driver.execute_script("document.getElementById('buttonid').click()")
Or something along those lines should work. Hope that helps you out.
If you don't get any solution with selenium and javascript, you can use Sikuli concept. To click that element, take the image of the 'Continuar' button and save it in resources folder.
String elementImg=Path of the Image;
screen.click(elementImg);
I could bypass this using driver.execute_script("document.getElementById('txtValor4').value = 123.45"), to pass the values into the textbox, so the button didn't got disabled and I could press the Continue button.
Even bypassing this, the result wasn't the expected! The value that I entered was supposed to be corrected by some sort of interest. But bypassing this, the value isn't corrected.
Today the user that asked the program told me that everytime I change the value inside this textbox, I must press the Calculate button.
So, instead of inefficiently bypassing this disable method, I could solve my problem using:
b = driver.find_element_by_xpath('//input[#id="txtValor4"]')
b.clear()
b.send_keys('123.45')
driver.find_element_by_xpath('//input[#id="btnCalcular4"]').click()
driver.find_element_by_xpath('//input[#id="btnContinuar4"]').click()
This way the tax value is corrected by interest and the website generate the .pdf with the exact value that I was expecting.
Many thanks for everyone that put some time and effort trying to help me.
I'm using Qwebview with Pyside/Qt to view an HTML page on a GUI I'm working on.
I need the possibility to add a search text function, otherwise it is useless for the purpose the GUI is made.
I've searched but I didn't find anything useful for build a code that search the text and scrolls down the page as it is made in the common browsers.
The only function I found is findText but it returns a boolean and I cannot see how it can be useful.
Do somebody have an hint / advice / guide or code for this request?
Thank you.
Okay, so it turns out that i had an example of this using a QTextBrowser, which has a lot of this built into utility functions.
You can still do it with a QWebBrowser though.
Bind ctrl-f to open a search panel, and then make it so that the search box sends out two signals;
(presuming it's a QLineEdit), returnPressed, and textChanged.
Each of them then calls findText on the QWebPage object.
The important part is setting the correct flag in the findText call (which you'll want to set with checkboxes in your search functionality, i'd say).
You set the flags so that HighlightAllOccurrences is not set.
I cannot see any way to get details on a selection. Are you sure that when you do not set the HighlightAllOccurences flag it does not scroll to the next selection automatically?
A button click in my app calls a view which does a few database changes and then redirects to a new views which renders html. When the user typically clicks on the link, he accidentally clicks on in twice to thrice in a couple of seconds. I want to block the view call if the same call was made less than 10 seconds ago. Of course I can do it by checking in the database, but I was hoping to have a faster solution by using some decorator in django.
This should help. It's a JavaScript to disable the button on click, enable it after the operation completes.
$(document).ready(function () {
$("#btn").on("click", function() {
$(this).attr("disabled", "disabled");
doWork(); //this method contains your logic
});
});
function doWork() {
alert("doing work");
//actually this function will do something and when processing is done the button is enabled by removing the 'disabled' attribute
//I use setTimeout so you can see the button can only be clicked once, and can't be clicked again while work is being done
setTimeout('$("#btn").removeAttr("disabled")', 1500);
}
More info here.
You should disable the button with JavaScript after clicking on it.
This way the user is unable to trigger the view multiple times.
No, you can't use decorators in Django to do that.
The methods in your views file are supposed to be telling what to show on your screen. Whereas, the template files are created to tell Django how you want to show them.
You want Django to not count two consecutive calls on same view.
The problem is:
What do you mean by "consecutive"? How fast should I click to make it "non-consecutive"? What if I write a script that does the clicks? How would you define consecutive then?
Even if you did do that above part using some hack, the next problem would be to differentiate between the requests that come from different users (to that view). How would you differentiate between them to determine the "consecutiveness" of a particular user?
Why make unnecessary changes to do all this stuff?
Django is supposed to be used along with other things too. I have learned this the hard way. Using Javascript is the only way to do it, without any problems.
Client-side, one click and poof! disabled. Very fast and you have the request in pool.
Doing this part is easy. Refer to these links for more info:

I have an issue when trying to test a web application with Selenium/Python. Basically I can't test elements of a pop-up window.
A scenario: I can test all elements for a page. But when I go to click on a button that opens up a small pop up box I can't test the elements on the popup. It's like the pop up isn't in focus or active.
I can test elements on the next page. For example click a button, brings me on to next page, and I can work with elements on the 'next' page. So it the problem seems to be popup specific.
I could post code but to be honest it might confuse at this stage. I may post code in a later post, thanks
There is a property called switch_to
Q: How do I handle pop up windows?
A: WebDriver offers the ability to cope with multiple windows. This is done by using the WebDriver.switch_to.window(knownName) method to switch to a window with a known name.
If the name is not known, you can use WebDriver.window_handles to obtain a list of known windows.
You may pass the handle to switch_to.window(handleName)
For example I used driverName.switchTo.window(driverName.getWindowHandle()) to get a hold of popups for which I didn't want to look for names.

For the Selenium RC API, you need to use the SelectWindow command to switch to the pop-up window. The window can be specified either by its name (as specified on the JavaScript window.open() function) or its title. To switch back to the main window, use SelectWindow(None).
