I dragged some files from "Nautilus File Manager" and Dropped to "Listbox1".
Normally, "Debug a" Should be Processed, but some files Will be Processed with "Debug B".

Public Sub ListBox1_Drop()


The actual file name is 'ABC+123.txt' but the variable F is 'ABC 123.txt'.
Apparently, the '+' character is incorrectly converted into a space.

I want to solve the error conversion, but I don't know what to do.

Thank you all.

 Have you tried using FromURL() as it should be an array of URLs

f = Replace(FromURL(f), "file://", "")

If Exist(f) ……

 Thank you BruceSteers.

I don't think it is necessary to "Replace()" because the "file://" has already been removed for the variable F in this program.

And I think there is a problem with the "FromURL()" function.

ex) ? FromURL("A+B")
    A B
    
This function is also converted to "+" symbols to space.

Thanks

I have found a possible solution to this, it is a little convoluted, but it works for me.

It does seem to be a bug in FromURL

my solution was to convert the + to an unusual ascii char then convert it back after FromURL…

Or maybe a hand made function that only converts any %xx codes to chars
I'll call it FromURI()

Or here is the same code but as an alternative to the Drag.Paste("text/uri-list") function you used that returns an array…

Just a little ore testing and i found gtk drag data is different to QT

So it seems gtk3 drag data looks something like this

FileName1\r\n
FileName2\r\n

but QT looks something more like this..

FileName1\r\n
-00:00:00\r
FileName2\r\n
-00:00:00\r

so here a URI-list decoder that should work with gtk and qt

Code (gambas)

1.   sHold = Drag.Paste()

Uhmmm. very interesting !

So, I propose:

Benoit has accepted this is a bug and has a plan to fix it by making FromURL() and Drag.Paste() only translate + to a space after a '?' Char in a URL.  8-)

It is now fixed in gambas master…
FromURL() does not decode '+' into a space before having encountered the '?'... (b610a6a2) · Commits · Gambas / gambas · GitLab

Well for the FromURL() function.
I'm not at home to test if it also fixed it for Drag.Paste() but if it uses FromURL() then it will be.

Thank you Benoit  8-)

After examining Drag.class and gb.gui.base source files I can say it is not currently fixed for Drag.paste()

I've suggested a fix to Benoit.
I'm sure it will soon be squashed <EMOJI seq="1f60e" tseq="1f60e">😎</EMOJI>

Currently, by using "FromUrl()" function:

I compiled the latest Gambas.
And the problem was solved.

Thank you everyone.

You're welcome  8-)

after fixing the interpreters FromURL() function Benoit then modified the Drag.Paste() uri-list function to use FromURL() and removed the code from gb.gui.base it used to use that was essentially the same as FromURL() anyway.

So both FromURL() and Drag.Paste() are fixed and gb.gui.base got a little lighter <EMOJI seq="1f60e" tseq="1f60e">😎</EMOJI>

Just a note….
When something like this happens and a bug gets fixed remember it's only fixed in the latest gambas master.

If you need backward compatibility (if your software is public for others to use they may not have latest gambas) you'll still need a workaround like some of the ideas we provided.

If you know your software is only going to be used on machines that will have latest gambas then it's fine and that bug will never occur again.
