How to set/change window.parent

[yanivt]

Hi
is there a way via cef to change Window.parent in the html.
mean:
i am using mdi application , and i have my main browser, i want to open new forms with new browser inside , and set the Window.parent to be the one that belong to my main window.
i can get the same behavior if its was iframe but i dont want to use iframe .

any idea ?
thanks

Window.parent cannot be set directly. You need to create the child browsers using JavaScript window.open and they need to have the same origin as the main browser.

Thanks for the clarification.
is there a way to handle the windows open , to put my new browser in my specific Form(windows/view) ?
(its mdi application so i want to use my view)

thanks allot

You can set the CefWindowInfo in OnBeforePopup.

great !
if i am working with CEFSharp is it , so i need to do it via ILifeSpanHandler ?
e.g.
chromeBrowser.LifeSpanHandler = xxxx

or other object/class

thanks

Thanks .

i follow the topic , and i manged to open my new window.
but its seems like i could not keep the parent document , like its not recognize in the child windows, what do i miss.
here is my code snippets
html

Code: Select all

<button onclick="window.open('main2.html');">Try new window open JS</button>


C#

Code: Select all

      public bool OnBeforePopup(IWebBrowser chromiumWebBrowser, IBrowser browser, IFrame frame,
        string targetUrl, string targetFrameName, WindowOpenDisposition targetDisposition, bool userGesture,
            IPopupFeatures popupFeatures, IWindowInfo windowInfo, IBrowserSettings browserSettings,
            ref bool noJavascriptAccess, out IWebBrowser newBrowser)
            {
            var xxx = (CefSharp.WinForms.ChromiumWebBrowser)chromiumWebBrowser;
            xxx.Invoke(new Action(() =>
            {
                Form3 c = new Form3(null);
                c.MdiParent = FormMain.g_singleFormMain;
                c.Show();
               
            }));
            noJavascriptAccess = true;
            newBrowser = null;
            return true;
}


thanks for any idea
btw
the major issue is to have access to parent js function

You are canceling the popup creation by returning true.

i appreciate your assistance.

i noticed when i return false - default window is started outside my MDI app.
i want to open the new window in my mdi , i managed to do that via the code i presented above.

my JS open.window looks like this

Code: Select all

        function openChild(file,window) {
                 childWindow=open(file,window);                       
                childWindow.parent = self;
        }


on standards chrome all works well. the only thing i wanted is to have access to parent from the new window/browser , while using CEF in my MDI app.
so, when we call to openChild method , i create the new form with the target url and set in in my mdi app (OnBeforePopup) , but the parent is not set as expected.

There is more - when i ignored the OnBeforePopup (lifespanhandler) , and let the default behavior to start the pop-up, even than i could not access to the parent ,although i set it in the JS method...

best regards

In viewtopic.php?f=18&t=18045#p47577 I've linked to the relevant code to host the browser as a tab, you can adapt that to host as a mdi child.
