Watch out for this bug! Progress bars do not work correctly if they are =
not created LAST in your program for some strange reason, what happens =
is that if manually set the progress amount (say 50 out of 100) it =
colors in only about 20% of the actual bar... but if you create the =
progress bar after all of your other controls it functions correctly.

2. Re: Progress bar in win32 lib
Note that progress bars actually work in a 'block' mode..
i.e. -- what gets filled *will* depend on it's defined size.
For example:
PBar = create(ProgressBar,"",Win,5,10,93,15,0),
PBar2 = create(ProgressBar,"",Win,5,35,123,20,0),
PBar3 = create(ProgressBar,"",Win,5,65,163,25,0)
...will all show exactly 10 'blue' blocks when they are *full*.
So if you:
setScrollPos(PBar_above,50)
...it will fill half-way for all the different sizes.
There is not necessarily any half-way if you haven't defined its displayed
size correctly.

This is what I did, pasted from my setup code:
progress_bar= create (ProgressBar, "", main_window,
scr_width/2-200,scr_height-160, 400, 20, 0)
setScrollRange (progress_bar, 1,100)
--a comment
setScrollPos (progress_bar, 50)
insert it into a window, run it, and half the bar is filled like it should
be.
now try inserting another control in the comment, using the create command,
run it again and you will see what i am on about.

4. Re: Progress bar in win32 lib
You are right, and to make it more interesting, try moving the
setScrollRange() down like I did here. It works again, as expected, even
though the bar is not defined last ???
include win32lib.ew
without warning
constant
main_window=create(Window,"",0,0,0,640,450,0),
progress_bar= create (ProgressBar,"",main_window,10,200,400,20,0),
mydummybutton=create(PushButton,"Hi !",main_window,10,300,400,20,0)
setScrollRange (progress_bar,1,100)
setScrollPos (progress_bar,50)
WinMain(main_window,Normal)

5. Re: Progress bar in win32 lib
Not that it makes any difference, but setScrollRange() for progressbars is
incorrect.
Should be:
elsif window_type[id] = ProgressBar then
if not sendMessage( id, PBM_SETRANGE, 0, pack_word( min, max ) ) then
...not... ( PBM_SETRANGE,True...
