Hi,
I have got two questions regarding using Win32Lib, can someone please
help me.
1. I successfully created a ListView in report style, how can I trap
doubleclick on any list item so that I can show detail of the selected
item. I tried onEvent, onClick, but none of these events triggers when I
double click the list.
2. How can I print formatted text in windows printer. I can print text
using wPuts() but if I put TAB control character in my text, it is not
recognised by my printer, it comes out as garbage character. I am using HP
Laserjet.
Regards,
Prasanta.

The print routines don't recognize tabs. If you are using fixed width
characters to print, you can use this routine to convert tabs into spaces:
-- size of the tab
constant Tab = 8
function tab_to_space( sequence s )
sequence new
integer at
new = ""
for i = 1 to length( s ) do
if s[i] = '\t' then
at = length( new )
new &= repeat( ' ', (Tab) - remainder( at, Tab ) )
else
new &= s[i]
end if
end for
return new
end function

Prasanta,
Use the "onMouse" event, and then trap for LeftDoubleClick,
approx. like this:
procedure List1_onMouse( int event, int x, int y, int shift )
integer index
index = getIndex(List1)
if event = LeftDoubleClick then
-- do whatever, using "index"
end if
end procedure
onMouse[List1] = routine_id("List1_onMouse")
