Key event not firing when pressing Enter on Android virtual keyboard

[snow]

Hi there,

my problem is that neither OnKeyDown nor OnKeyPress is firing when I press the Enter/Return key on the Android virtual keyboard (GBoard) inside a TUniEdit component.

Inside a TUniComboBox it's working though...

Any ideas how to catch the event?

Using Professional Edition v1.90.0.1563

Attached is a simple project where it can be reproduced.

Thanks in advance.

How should we reproduce this?

Just set Breakpoints and touch the mentioned button when inside the edit... shouldn't stop there.

Thx.

Have you tried setting a breakpoint other than "Exit"?

[snow]

Yes... Exit is not the problem.

Could you already reproduce the problem?

Sorry, but how to activate the Enter key in gboard in android?

[snow]

I mean the blue Open/Ok-Button (see attached screenshot).
When pressing this button inside a TUniEdit none of the above mentioned key events is fired. Instead focus changes to the next control.

[Sherzod]

Well, I think this is not a uniGUI issue.

[snow]

But why is it working in TUniComboBox and not in TUniEdit?
This is a problem as we often catch KeyDown-Event for Return in our application...

Hello, sorry, but this button has changed its meaning. They are now used as Tab, not Enter. So try to check if when you press the button Tab is activated.

This impressed me when I want to switch from Tuniedit to another component with onkeypress event handling. !

Unfortunately, there's no key event fired whatsoever when pressing this button inside a TUniEdit.

Real this key do: go to Next Control.

To  check if Enter Key is work, try to connect standard keyboard and get keypress event

[snow]

With a standard keyboard everything work's fine.

We are using our software on different scanner models. On models with hardware keyboard there's no problem.

The problem appears on models without hardware keyboard where the virtual keyboard has to be used.

Here no keyboard event is fired whatsoever... instead focus changes to the next control.

As this behaviour of TUniEdit is different from e.g. TUniComboBox your help on how to catch OnKeyDown in this case is greatly appreciated...

I am sorry but changing controls with Enter key from Android keyboard, maybe is made by javascript (onClient Side) and this is not fire onKeyEvent (is not going to) on server.

Here @Sherzod maybe will help.

Try this approach for now:

UniEdit1.TabStop = False

Did you know that barcode scanners can be programmed to use a different prefix or suffix character, and your software can handle that character (like STX, or #, or whatever) in text fields. Not a much better idea, but it might turn out to be a solution.

Another way is to change the default Android keyboard to another one.

Another way you can also use "blur" on the client side and send an ajax event with some commands.

1. YOUREdit.JSInterface.JSAddListener('blur',
                          'function(){this.setValue(YOURFUNCTION(this.getValue()))}'
                    );
or 2. ' ajaxRequest(this,''brender'',["_sKey_"]);'
or 3. uniSession.AddJS('ajaxRequest (' + YOURForm.JSName + ',''blur'',["this=" + ' + YOUREdit.JSName + ',"_sKey_"]);');

Unfortunately, this doesn't change the behaviour at all.

We're already using special prefixes/suffixes for the scanners to handle scans.

However, in this case nothing is scanned but the program shall handle input via the virtual keyboard.

Different virtual keyboards don't seem to help. With Samsung virtual keyboard (on mobile phone) it just behaves the same.

I don't see how "blur" event can help me in this case. It fires every time the control loses focus... is there any way to catch the pressed key with this event?

Are you sure? This approach works for me.
