Contents of JEWL Editbox not consistent

Contents of JEWL Editbox not consistent

[tolkamp]

In my application the selected file name  is written in an Editbox.
When an new (second) file name is selected this is also displayed in
the Editbox.
When the contents of this Editbox have to be edited, first the mouse
pointer have to be placed in the Editbox, by doing this the original
(first) file name again is coming back in the Editbox. Why remains the
second file name not displayed?

Sorry, cannot say anything without more source here ;)

P.S. Is this for a personal project or for a school homework ?

After some attempts I found the solution:
Updating of an already opened Editbox must be done with the procedure
Set_Text(String), then it works correct.

As has been pointed out, a small chunk of code that demonstrates the
problem you are asking about is usually helpful, so all of the below is
just a shot in the dark.

Full disclosure: I haven't actually ever used JEWL, having just heard
about it recently on this forum, but I did read the documentation
today.  I'm looking forward to tinkering with it.

Anyway, in the JEWL.Windows user manual, section 1.3, there's a line
that says "Note that if the Set_Rate button is pressed again, the value
that was entered into the edit box will still be there unless it has
been explicitly altered by the program."

In your post, you don't say how the second filename is being put into
the Editbox.  I think you have two options: using Set_Text or letting
the user change it interactively.  I assume using Set_Text is what the
note in sec. 1.3 means by "explicitly altered," so I further assume
that your problem is that the user is manually editing the Editbox, but
you never take that newly-entered text and assign it to the variable
that holds the state of the Editbox string.

In this case, it looks like the Modified(Editbox) subprogram described
in section 4.1.3 might be helpful.  Use that to detect when the user
has fiddled with the string manually, use Get_Text to get the modified
string, and then give the gotten string to Set_Text to explicitly
update the Editbox string.

And if this is completely wrong, please see the disclaimer in paragraph
2 and post some example code. :-)
