How to resize popup windows? resizeTo() resizeBy() not working

[Mike Baker]

Hi,

I'm trying to resize a popup window using the javascript functions resizeTo() and resizeBy() but nothing happens when these functions are called in cefsharp. Are resizeTo() and resizeBy() supported by cefsharp for popup windows or is there another workaround to enable resizing of popups?

The popup window is a child window created using window.open(). The resize works fine in a native chrome browser but nothing happens when executed inside cefsharp. 

Thanks.

Version? WinForms or WPF?

Also it's worth trying to identify if this is an upstream CEF issue or a CefSharp problem

We are using CefSharp.WinForms 41.0.1

According to https://bitbucket.org/chromiumembedded/cef/issues/698  it looks like it might be an open request with CEF.

I tried the CefBuild TestApp and it doesn't appear to work in that either.

CEF	3.2494.1321.ge343da7
Chromium	47.0.2494.0

In the next version (currently `43.0.0-pre02`) you can get the popup window handle and move it around yourself. With a bit of work you could likely intercept the JS methods and move the window around yourself. (Not tried it, just a rough idea at this stage).

Not sure if this helps.

Thanks. We will keep an eye on the next release. In the meantime, we intercept the javascript and use the following native methods to get the window handle and perform the resize:

FindWindow

GetWindowRect

GetClientRect

SetWindowPos
