I am sure that the more learned who frequent these pages will correct me if I am wrong again, but I believe the answer is no, you cannot stop people looking at your source code.
There are many examples to be found by googling "disable ctrl U or "disable right click", but I suspect if the perpetrator is persistent enough they will get your source code displayed. . .
eg (related but not specifically for wx5) https://www.bloggerspice.com/2016/01/how-to-Protect-your-Website-by-Disabling-page-source-view.html?m=1

Thank you, Esahc, for quick answer...
I only have to hope that no-one will steal it...
Hello Tom
There is no way you can prevent your source code to be exposed.
Even if you could block the Ctrl+U then people can download a html page.
Try to download a page from web and then open in Notepad++ - it is the source you see.
It is needed for the browser to show you something meaningful on your monitor :-)
If you have some valuable code you want to not have shown, then you could maybe use some PHP and include's.
This will not be shown in the browser.

Good answer, John! Will try that.
If it is javascript code you can obfuscate it. But I would not do it unless the code was really valuable.
And as far as I know, there are decompileres so.....

So, there is no win situation...
Thank you, guys!

... for block Ctrl+U enables line number 27 :

I like it!
(But Ctrl+U will still work)
... no!
>> HERE I have enabled the line of code number 27 :
[27] // uKey = 85;
[27] uKey = 85;
But you can still download the page and see all the code :

... ... of course ...
... it's in the premise...
.
- if you really want it, you can get it
... we talked about Ctrl + U ...
... then you can certainly do everything ...
I know KolAsim - but what would be the meaning by that. I just try to tell it has no meaning.
It is like telling a person he can secure his bicycle with a strong chain that locks the front wheel - that will not stop people from stealing the bike. It can easily and quick be collected by a van.
Then you can tell him to lock the bike together with a lamppost.
That will not prevent people with grinders to take the bike.
You can secure your bike by putting it in a vault - and you can secure your code by not putting it on the web.
Important is that people is aware that whatever is put on the net can be copied. You can make it more or less hard - but not impossible.
... certainly, I agree, and it has already been said before in the presuppositions ...
