JEWL Editbox_type output numerics

JEWL Editbox_type output numerics

[Rego]

Hi,
I have a JEWL editbox_type which I want to output a float number in a
0.00 format (instead of exponencial 0.0e0 format). The default way
(which shows exponencial) is to do
Set_Text (My_Editbox, Float'Image (My_Float)),
so but how do I do this the other way?
Tkx

Output into a string and then send the string to JEWL.

In one step you can do this with:

   http://www.dmitry-kazakov.de/ada/strings_edit.htm#6

e.g.

   with Strings_Edit.Floats; use Strings_Edit.Floats;
...
   Set_Text (My_Editbox, Image (My_Float, AbsSmall => -2))

Within the language, you use an instantiation of Ada.Text_IO.Float_IO to put the 
value to a string, then pass (something derived from) that string to Set_Text.

Or you can use a library such as the PragmAda Reusable Components; see 
PragmARC.Images:
