Virtual Keyboard

[ArtyP]

Hello,
I'm currently supporting CEFSharp app. After updating from version 39 to 49 virtual keyboard does not appear any more. I have read all issues I had found and tried all possible combinations of them . No success.
The list of workarounds I have tried:

• set FocusHandler to null;
• set MultiThreadedMessageLoop to false;
• automatically display the touch keyboard;
• Set browser focus;
• Enabling touch-events;
• some other tricks, which did not help.

Then I have installed Visual Studio on tablet, build a WinForms example 49. But keyboard still does not appear. My question is, what should I do to make keyboard appear in this simple example.

System:

• Lenovo miix 3 1030
• CefSharp version 49.0
• x86
• Win10
• WinForms

Steps will reproduce:
Start CefSharp.WinForms.Example on tablet.

In cefclient (from http://cefbuilds.com) keyboard works properly.

Does the problem reproduce in 47.0.4? You might be better to rollback a version.

Did you explicitly use 3.2623.1396?

Also make sure you don't have a physical keyboard plugged in when testing.

Thanx for your help. After rollback to 47.0.4 my project works perfectly fine for me.
In CefSharp.WinForms.Example you need to set FocusHandler to null. Otherwise virtual keyboard appears but keypress does not work.
Should we close the issue?

Should we close the issue?

I will assign this to the 51.0.0 milestone, I'll let you know when a test build is available. If you have time I'd appreciate if you could re-test.

[ArtyP]

Sure.

The master branch has been upgraded to CEF 2704.1415 which is based on Chromium 51.0.2704.63. If you have time to download the source and test this out that would be much appreciated.

A -pre release based on this version will likely be released in the next couple of weeks.

@ArtyP 51.0.0-pre01 packages are on Nuget.org, appreciate if you could test them out.

We are developing a kiosk solution using Windows 10 and CefSharp but we have the same problem with the touch keyboard not appearing in 49 and 51. We tried downgrading to version 47 hoping that would fix it, but no luck. When using a Chrome browser, the keyboard appears.
So we are wondering: Are we even initialising CEF correctly? What are the required settings in CEF for making the onscreen keyboard appear?

Your using WinForms? If your using WPF then that's a totally different issue.

When using a Chrome browser, the keyboard appears.

It's not relevant to compare to Chrome in this instance, see https://github.com/cefsharp/CefSharp/blob/master/CONTRIBUTING.md#cefsharp-vs-chromium-embedded-frameworkcef

What are the required settings in CEF for making the onscreen keyboard appear?

There are none, CefSharp has no control, it's just a wrapper. It either works or it doesn't.

[martin-k]

Its a WinForms project.
So if I understand you correctly I should be looking for solutions on the CEF forums instead? Sorry for posting in this thread then, it just sounded exactly like our problem. You can delete these comments if you wish.
