How to disable printing in CEF3?

[crast]

Hello!
I need to disable popup print dialog box.
I'm trying to reload PrintHandler in CefBrowserProcessHandler, but print dialog is pop up. How to do that?

This is not currently supported. See https://code.google.com/p/chromiumembed ... il?id=1283.

You could overwrite window.print with a dummy function. In CefLoadHandler::OnLoadStart call frame->ExecuteJavascript("window.print=function(){}"); To disable "Print..." option from mouse context menu see CefContextMenuHandler.

This is not currently supported.

I was confused by this preprocessor definitions:

ENABLE_PRINTING=1
ENABLE_FULL_PRINTING=1

In CefLoadHandler::OnLoadStart call frame->ExecuteJavascript("window.print=function(){}");

It works. Thanks.

Hi,
I am working on CEF application with CEF sharp with windows.

n CefLoadHandler::OnLoadStart call frame->ExecuteJavascript("window.print=function(){}");

will this work with windows applications as well?

The override the function look like this

public void OnFrameLoadStart(IWebBrowser chromiumWebBrowser, FrameLoadStartEventArgs frameLoadStartArgs)
{
frameLoadStartArgs.Frame.ExecuteJavaScriptAsync("window.print=function(){}");
}
Still print dialog pops up
Please help on this

It worked by Modifying CEF Sharp source code by calling

frame->ExecuteJavascript("window.print=function(){}"); in CEfSharp.core ClientAdapter.cpp class OnLoadStart method

You can implement CEF menu handler and remove the print command.
