I'm creating a touchscreen application and i need help on a few things...
1) On one of my screens i have multiple text fields. As it's touch
screen i have an onscreen keyboard.
I know i can give each field 'focus' by touching the relevant field. But how
can i enter text into each field independant of eachother??
2) I can write to text files easily but i would like to have a strutured
output. IE
ITEM A £9.00 ITEM AA £2.30 ITEM AND HS .90
how can i get this? as all its comeing out with at the moment is...
ITEM A£9.00 ITEM AA£2.30 ITEM HS.90
but there is a catch to this problem. the text is imported from another .TXT
file per item. which the .TXT file is created on screen. so every item will
have a different length. unknown until the user puts in the name of the
item.
3) Thanks in advance.
Hello Glyn
for 1)
I'm not sure I have understood your question, but look at the focus command, it can help.
for 2)
You can use
put "%" & maxlength & "s" into f
put format(f,thestring) after URL(file...)
but you will get right justified strings of length maxlength. Look at the transcript dictionnary for details.
To get left justified words or strings of length maxlength, I would use something like:
function trailingspaces thestring,maxlength
put (maxlength - the length of thestring) into n
if n < 0 then
-- some error management here, perhaps some truncation of thestring
end if
repeat n
put space after thestring
end repeat
return thestring
end trailingspaceand then:
put trailingspaces (theitem,maxitemlength) & trailingspaces(theprice,maxpricelength) & return after URL (file:....)
just choose your maxlengths conveniently (that is, at least two chars more than the longest item). You can compute it by script.
Hope it helped
