Scrolling Progressbar

[Psych]

Can we have a progressbar that just scrolls (indicating it's busy), I'm sure you've seen this, a few blocks that flow across the bar, values make no difference.
Any ideas?

Why not shove a progressbar gadget inside some kind of timer or thread?

[Psych]

I can have the progress changing but that fills the progressbar, that isn't the effect I am looking for, what I'd like is to have maybe 2 or 3 bars scroll from left to right continuously.
I think the style is called marquee, or something like that.

Code by Sparkie :

Code: Select all

; --> *** Requires WinXP with XP skins enabled *** 

#PBS_MARQUEE = 8 
#PBM_SETMARQUEE = #WM_USER + 10 

If OpenWindow(0, 0, 0, 320, 160, "", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
  ProgressBarGadget(0, 10, 30, 300, 20, 0, 100, #PBS_MARQUEE) 
  ButtonGadget(1, 110, 70, 75, 20, "On") 
  HideGadget(0, 1) 
  
  Repeat 
    Event = WaitWindowEvent() 
    
    Select Event 

      Case #PB_Event_Gadget 
        
        Select EventGadget() 
          
          Case 1 
            If GetGadgetText(1) = "On" 
              SetGadgetText(1, "Off") 
              HideGadget(0, 0) 
              SendMessage_(GadgetID(0), #PBM_SETMARQUEE, 1, 100) ; on 
            Else 
              SetGadgetText(1, "On") 
              SendMessage_(GadgetID(0), #PBM_SETMARQUEE, 0, 0) ; off 
              HideGadget(0, 1) 
            EndIf 
              
        EndSelect 
    EndSelect 
    
  Until Event = #PB_Event_CloseWindow 
EndIf 

Alter the value 100 to alter the animation speed etc.

Thanks.

Another approach would be to display the progress bar as an animated GIF image. In the German forum in a similar thread (http://www.purebasic.fr/german/viewtopic.php?t=19786) the following links were posted which allow you to interactively design your own customized download indicator in different graphical shapes and colors. If you are satisfied with your result you are allowed to download the animation as a GIF file:

To display the animated GIF image you can utilize the web gadget as PB already demonstrated in a rather old posting (which has to be adapted to PB 4):

Thanks again, I think the send message approach does exactly what I need, it's a windows only app anyway. I think it looks a little nicer than simply displaying a wait message.

A small thing, when you stop it, that's all it does, stop... It doesnt go back to it's original behaviour.
Any way to get it to report progress again?

[srod]

Not sure what you are after but

Code: Select all

SetWindowLong_(GadgetID(0), #GWL_STYLE, GetWindowLong_(GadgetID(0), #GWL_STYLE) & ~#PBS_MARQUEE)

will remove the marquee style and you can then use SetGadgetState() etc. to set the progress position.

[Psych]

I was actually just reading about that on MSDN.

We are very fortunate to have a community of people that know this stuff, would of taken me ages to figure out what to put in there.

Thanks srod.

[Psych]

I modified the code example to take the style off, and that works like a charm, should removing the tilde (~) not set it back on again?

Code: Select all

SetWindowLong_(GadgetID(0), #GWL_STYLE, GetWindowLong_(GadgetID(0), #GWL_STYLE) & #PBS_MARQUEE)

[Psych]

Ok, I'm stupid, you got to OR it.

Silly me.

[srod]

If you want to toggle the style then use Xor :

Code: Select all

SetWindowLong_(GadgetID(0), #GWL_STYLE, GetWindowLong_(GadgetID(0), #GWL_STYLE) ! #PBS_MARQUEE)

Here a small example like Shardik wrote.
Works on all windows and looks better

I don't get it... Why does the code from Sparkie posted srod not work here? Nothing moves.
Also this SetWindowLongPtr_() thing doesn't work here.

P.S.
Skin support is activated. Using XP SP3.
