Original issue 24 created by arnaud.brochard on 2014-01-06T12:56:37.000Z:

What steps will reproduce the problem?

Download and run latest distribution

What is the expected output? What do you see instead?

Expected behavior is a visible and blinking cursor on text fields. But no cursor is visible at all.

What version of the product are you using? On what operating system?

jcef_binary_3.1650.1501.9_windows64_preview
Windows 7 x64
JDK7u45 x64

Also tried with win32, same behavior

Please provide any additional information below.

In debug mode, the onCursorChange method of the MainFrame class is often called, but no cursor is visible

I am having the same issue.

I just built JCEF according to the instructions (Windows 7 x64, JDK 7u45 x64). Had to add NULL as value for the windows_sandbox_info parameter of function calls to CefInitialize and CefExecuteProcess to get it compiled.

Caret behaviour is indeed very strange. Navigation with cursor keys has no effect, also, Shift + cursor key doesn't select text as usual. Home and End keys don't work, either. Mouse selection does work, however.

I suspect it's not just an issue with the caret not being displayed, but some deeper problem. Looks to me as if caret events are not passed to the underlying control.

I'm just evaluating JCEF for a project and, unfortunately, this issue is a showstopper for me. I tried to build the cefclient2010 project to investigate whether this might be a Windows issue but I'm getting a build error I can't resolve (MSB6006: cmd.exe exited with code 4; no helpful information on Google found on this).

If I can be of any assistance in resolving this problem please don't hesitate to contact me. I can also offer some development resources for JCEF in exchange for being able to use it (I'm a fairly competent Java developer with JNI experience and some experience in C and C++).

Thanks, Leo

@ commentcomment 1.: JCEF is currently demo/prerelease quality, so there will likely be a lot of showstopper issues :). In this particular case we may not be setting the focus correctly after creating the off-screen browser.

All of the source code for JCEF is available. Feel free to submit issues and/or patches for any problems that you run into. You can also ask questions at http://magpcss.org/ceforum.

I also suspect there's a collection of small issues :

• I solved the tab situation with a simple canvas_.setFocusTraversalKeysEnabled(false)

• Arrow keys are not responding on a Windows machine (probably some wrong/missing code in Java_org_cef_CefBrowser_1N_N_1SendKeyEvent, I'll try to debug it)

• Cursor is still missing (no idea here)...

You can avoid this issue by using the windowed rendering mode supported by newer JCEF revisions.

Just rebuilt and tested latest revision (r90 along up-to-date CEF), confirmed the cursor issue is fixed in window rendering mode (but not in OSR mode, as indicated)

This can probably be fixed for off-screen rendering by calling CefBrowserHost::SendFocusEvent when the Java canvas receives focus.

I found a workaround

browser_ = client_.createBrowser(startURL, useOSR, isTransparent);
browerUI_ = browser_.getUIComponent();
browerUI_.addFocusListener(new FocusListener() {

        @ Override  
        public void focusLost(FocusEvent e) {  
            browser\_.setFocus(false);  
        }  

        @ Override  
        public void focusGained(FocusEvent e) {  
            browser\_.setFocus(true);  
        }  
    });   
}  

You can put in org.cef.browser.CefBrowserOsr.java in createGLCanvas()

To confirm, I just tried the .setFocus workaround in OSR mode on Linux, and it works perfectly. Thanks for that.

Hi, so I came across the same issue. Maybe the code has changed since your last comment, so I had to add in MainFrame.java around line 224:

browser\_ = client\_.createBrowser("http://www.google.com",  
                                 osrEnabled,  
                                 false,  
                                 requestContext);  
browser\_.getUIComponent().addFocusListener(new FocusListener() {  

  @ Override  
  public void focusLost(FocusEvent e) {  
    browser\_.setFocus(false);  
  }  

  @ Override  
  public void focusGained(FocusEvent e) {  
    browser\_.setFocus(true);  
  }  
});

Duplicate of #180.

• set state to "open"
