问题 How to get screenshot of browser in DCEF3? I create browser like this without VCL. The TakePicture method will only work if No debugger is used If ShowWindow is used var info: TCefWindowInfo; Settings: TCefBrowserSettings; begin FillChar(info, SizeOf(info), 0); info.width := width; info.height := height; FillChar(Settings, SizeOf(TCefBrowserSettings), 0); Settings.Size := SizeOf(TCefBrowserSettings); GetSettings(Settings); CefBrowserHostCreateBrowser(@info, FHandler, FDefaultUrl, @settings,

问题 I'm trying to use following procedure in Delphi XE2 with Chromium component (version 306): procedure TForm1.Chromium1BeforeBrowse(Sender: TObject; const browser: ICefBrowser; const frame: ICefFrame; const request: ICefRequest; navType: TCefHandlerNavtype; isRedirect: Boolean; out Result: Boolean); but it's not working. Delphi doesn't recognize onBeforeBrowse event. Chromium seems to be correctly installed, samples are working, and I'm trying to add onBeforeBrowse event handling in GuiClient

问题 I'm trying to iterate the DOM using TChromium and because i use Delphi 2007 i can't use anonymous methods, so i created a class inherited of TCEFDomVisitorOwn. My code is as below, but for some reason the 'visit' procedure is never called, so nothings happens. unit udomprinc; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, ceflib, cefvcl; type TForm1 = class(TForm) Chromium1: TChromium; procedure FormCreate(Sender: TObject); procedure

问题 When using DCEF3 TChromium, how can i keep the session alive ? For instance, if i go to a web-site and login on it, when i close my app and open it again, i need to login again. I want to keep the session alive, just like it would be if i use Google Chrome. I tried to add 'CefLib' on my app 'uses' clause and set 'CefCache' like the code below, but although i can see files being stored on 'cookies' folder, it seems to make no difference in keeping the session alive : program Project1; uses

问题 I found the brilliant Delphi Chromium project for embedding Chrome in a Delphi form. It works well in Delphi7 after a bit of hacking and I can get the demo app running. However when I do my own app with the component, I can't load my own url. I get a access violation. Chromium2.Browser.MainFrame.LoadUrl('http://www.example.com'); The TChromium component is working and I have all the DLLs in the right place, since if I set DefaultUrl it works fine. I have Chromium2 in a TPageControl page and

问题 I would like to simulate the mouse click on a page. I'm using TChromium in Delphi. I've tried the following code, but it did not work. code := 'document.getElementById(_2lkdt).click();'; Chromium1.Browser.MainFrame.ExecuteJavaScript(Code, 'about:blank', 0); The page button is this: <button class="_2lkdt"> <span data-icon="send" class=""> <svg id="Layer_1" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24" width="24" height="24"> <path fill="#263238" fill-opacity=".45" d="M1.101 21.757L23

问题 I am trying to enumerate DOM nodes using the following code (under XE2). I have borrowed most of this from answers given here in SO, but for some reason it's not doing anything. IOW, ProcessDOM() is not ever getting called. And, I am at my wits end. Could someone show me what I am doing wrong here. Thanks in advance. procedure ProcessNode(ANode: ICefDomNode); var Node1: ICefDomNode; begin if Assigned(ANode) then begin Node1 := ANode.FirstChild; while Assigned(Node1) do begin {Do stuff with

问题 To get a particular DOM node embedded in the current web document from a TChromium instance, using its ID, you use ICefDomDocument.getElementById(). But how do you find elements by the NAME attribute? Javascript has the document.getElementsByName() method and TWebBrowser (that wraps IE) has a similar call, but I can't figure out how to do this with TChromium. I need to find some DOM elements that have NAME attributes but no ID attributes. I searched the ceflib unit and did not see anything
