In my web application a lot of popups opened from the parent window using 'window.open'. So I want to close all those popups when my application's main window is closed. How can I do that?
It's a bit problematic to know that the user closes the window but assuming you do achieve that (by a close button or subscribing to the beforeUnload event) you can close the opened windows by following the next bullets:
When opening a window, save its
object which is returned from the
window.open method (preferably to an
array so you have all objects in a
central place).
When you find out the main window is
closing, execute the close method
on the saved window objects.
Another possibility:
Use timer on the opened windows to
check if opener is defined (you
can try to use typeof on a method in
the opener page).
When you find out the opener doesn't
exist, close the window.
There's no callback that will notify you that the user closed his browser.
its not possible! You cannot catch browser close event.
You can use model popups to be sure user closed popups before closing the main window.

I have 5 windows which i push and pop via a stackview. In the emulator the new window called by push gets on top as it should. However on my android it spawns behind the starting window. I tried using lower() to set the starting window behind the new window with no success
//start page
Button{myStack.push(page_2); lower()}
I also tried rasing the new window on completion with no success
//new page
Component.OnCompleted:raise()
However close() works properly closing the start page and thus making the new page visible.
//start page
Button{myStack.push(page_2); close()}
Qt doc goes as follows for lower()
lower()
Lowers the window in the windowing system.
Requests that the window be lowered to appear below other windows.
and for raise()
raise()
Raises the window in the windowing system.
Requests that the window be raised to appear above other windows.
Is my code correct? why does close() work and the others dont't
First of all, I don't think that Qt supports multi window on Android. One single window only.
Second - what you posted is not even valid QML code.
Third - in that case you use the the stack view within a single window, and push different GUI elements onto it. Refer to the documentation.
Whats the difference between QDialog::show() and QDialog::open()?
show() will just show you the dialog without affecting the other windows in your program. open() will show() the window + prevent other windows from being accessible through setWindowModality(), i.e., it becomes a modal window.
This is useful if you want to open a file, for example, and you don't want the user to be able to do anything in the program until a file is chosen and that dialog is closed.
Quoting from Qt's manual:
A modal dialog is a dialog that blocks input to other visible windows in the same application. Dialogs that are used to request a file name from the user or that are used to set application preferences are usually modal. Dialogs can be application modal (the default) or window modal.
When an application modal dialog is opened, the user must finish interacting with the dialog and close it before they can access any other window in the application. Window modal dialogs only block access to the window associated with the dialog, allowing the user to continue to use other windows in an application.
The most common way to display a modal dialog is to call its exec() function. When the user closes the dialog, exec() will provide a useful return value. Typically, to get the dialog to close and return the appropriate value, we connect a default button, e.g. OK, to the accept() slot and a Cancel button to the reject() slot. Alternatively you can call the done() slot with Accepted or Rejected.
As it is stated in the doc, QDialog::open()
Shows the dialog as a window modal dialog, returning immediately.
whereas QDialog::show(), which is in fact QWidget::show(), will only show your dialog as a standard, non-modal widget.
Scenario:
Enter a keyword (Position) in a textbox
press Tab or click on the next element
A window popup appears
a list of position matching the criteria will be listed
click the required record
Popup window closes automatically
Alert will be displayed
have click on ok button of alert.
switch to main window and check the position details
Question :- i found many solutions in the site but all are about performing actions on window popup and close the popup then switch to alert or main browser
but my application closes the popup window automatically after selection,hence i cannot use the driver.close() or driver.switchto.defaultContent().
If i dont close the driver (for popup) im not able to identify the next alert displayed after popup.
if i switch directly to mainwindhandle, the alert dismiss is happening instead of accept.
Please anyone who know how to switch from window popup to alert without popup close help is needed...
Thanks ....
If alert dismiss is happening when you are trying to accept it, why don't you use alert.dismiss(), it will probably accept the alert in your context.
When you switch to the popup window, the driver focus is on the popup window. What you might want to do is, just after clicking the required record, switch to the main window then accept the alert.
This must be helpful for you . From your questions, Even after your pop up closes automatically you must be able to access your parent window element by switching back to it. There is no need of driver.close() all the time. Here is the code,
// do something with the pop up and it closes automatically here.
driver.switchTo().defaultContent();
driver.switchTo().frame("your parent window mainframe"));
// try to access your parent window element here
I need to know in my app if a modal window is opened when I click on a button.
So I'm searching for a method which permits to know if a modal window is opened in my application or no, and which returns the window (or NULL)
Is it possible?
See QApplication's static activeModalWidget
i want to open a popup window when user leaves tab or closes browser, the available option with me was window.open, but with that, it asks for popup blocker, if it is not enabled, i tried every possible ways to ignore popup-blocker but in vain, i tried onunload, onbeforeunload, but it does not works, i also tried to use modal dialog, before the tab/browser, i used it in onbeforeunload event, but it shows a browsers alert message, which i dont want, my simple requirement is, i need a popup window (if possible) or modal dialog, on the close of tab/browser, but should ignore popup-blocker, i guess with modal dialog, i dont need to worry about popup-blocker, because that wont be the new window, but how i would be handling it, while user closes tab/browser. If any of the above option is not possible, can anyone help me with any other possible alternative, or helpful articles.
Edited Question
i used the below script and with that i can open a new popup window on link click, without popup-blocker interfering in it
$('a[href=http://www.google.com]').click(function(){
window.open(this.href);
return false;
});
then why its not possible for the closing events.
You can't - because that's what popup blockers do: they block popup windows (i.e. calls to window.open or invocations of target="_blank" links) unless it is directly in response to a user mouse action.
Opening popups when a browser window is closed was a common tactic of "pop-under" ads in the early 2000s, and it irritated users, that's why Firefox and IE6's popup blocker block them, and there is no way around it for you unless you ask the user to disable their popup blocker on your site (and I think you'll find most of them will have no idea how to do that).
What are you trying to accomplish anyway? What is the content of this popup that you want the user to see? What other approaches have you tried?
Exact duplicate of your previous question....
I'll post my answer for it here as well though...
Popup blockers are designed to prevent this behavior.
I would suggest using a modal window instead of an actual browser window. I don't think that these get blocked because they are opened within the page itself.
As for the event... You could do something like...
window.onbeforeunload = function whatever() {
//Do code here for your modal to show up.
}
If you are just trying ot give a warning or something you could do
window.onbeforeunload = function showWarning() {
returnString = 'Whatever you want your message to be....';
return returnString;
}
By returning something in the onbeforeunload statement it will show a confirm box with your message in it.
Popup blocker will not block the opening of popups if the javascript code which opens the popup is executed on user's direct action like click, keypress, drag, etc.
