Make vertical scroll bar darker
-
vertical scroll bar indicator in the vertical scroll bar is just so hard to see - the colors aren’t contrast-y
My “thumb” in Win10 already has “good” (I won’t go so far as to say “great”) contrast; maybe post a pic of yours?
-
Yes, that’s it, what you’re calling the “thumb”.
On my $work computer - image site is blocked. However the pic you posted is pretty much exactly what I see - to me there’s very little contrast on that and I can barely see it. I can see @Ekopalypse much better.
Cheers.

It seems to be the only way to create some sort of overlay,
from what I understand, because the Windows message WM_CTLCOLORSCROLLBAR
is not sent in our case.
In my opinion, this would mean that, via the respective
Scintilla window procedure, one must act on WM_PAINT, as described here in an example,
and a new, darker(?) thumb must be painted over the original thumb.
How performant this is … ?? -

If you copy an image to the clipboard and then try to Ctrl+v it into your posting here – it’s blocked??
That seems really odd; I thought my work company was militant but yours takes it to a new level. :-)How performant this is … ??
We won’t know until we see your demo of it. :-)

By the way, I doubled checked that scintilla does not receive the MW_CTL… message.
Here what I received during testing (the number after the message are the wpara and lparam values)

I haven’t finished PySnack or ThemeBuilder yet and now you ask for a demo for it? :-DI will probably try it sometime today :-D

Sometimes the “small” ones are a nice diversion when the “bigger” ones get bogged down.
Accomplishing a “small” one reinvigorates you for the others. :-) -

Sorry, you’re right, didn’t know we could post photos directly in here, thought we had to link to that imgur site (which is blocked for me).
I can see the one on the right much clearer. Note, that’s with my mouse clicking on the “thumb” to scroll / move it - it highlights darker when it’s clicked on.
@Ekopalypse @Alan-Kilborn
Please don’t waste any time on this unless it truly intrigues you. This was just a question to see if I was missing something in Style Configuration or Themes. If we need to hook Windows events that aren’t currently passed, then it’s going way beyond how “easy” it could be and I can live with it.Cheers.

Yes, I see your complaint about lack of contrast. And yes, my thumb also gets way darker when I’m using it.

Our “recent” upgrading of the forum software changed this. Sooooo much easier to just paste!
I can’t believe the amount of effort I went to before, to go to imgur, paste it there, create a link, blah blah blahdon’t waste any time on this unless it truly intrigues you
Oh, it intrigues @Ekopalypse , I have no doubt.

Seems I can’t see, again, the wood for the trees.
According to MSDN there is the function GetScrollBarInfo,
which provides information about the scrollbar.e.g. these values
cbSize : 60 rcScrollBar left : 1429 top : 174 right : 1446 bottom : 702 dxyLineButton : 17 xyThumbTop : 342 xyThumbBottom : 423 reserved : 0 rgstate : [0, 0, 0, 0, 0, 0]The fields of interest are rcScrollBar and
dxyLineButton, xyThumbTop, and xyThumbBottom.The thing that confuses me now is the fact,
that these values are only conditionally compatible
with the values provided by UISpy.rcScrollBar is ok, from UISpy I get (1429, 174, 17, 528) = (left, top, right-left, bottom-top)
but for the thump I get from UISpy (1429, 516, 17, 81)
Where does the 516, the top value actually come from?
1429 = left
17 = dxyLineButton
81 = xyThumbBottom-xyThumbTop=423-342
516 = ?? (actually top but it is supposedly 342)What didn’t I understand?
-
Oh, I see - the thumb coordinates are relative to the scrollbar coordinates.
-
Ok, so I’ve tried it and I couldn’t make it work.
From msdn I understand that painting should take place
within WM_PAINT and start with BeginPaint and end with EndPaint.
That’s what I did and I can see the changes for a very short time then
it disappears again.
Then I tried approaches with BitBlt or StretchBlt but failed again.
Now I’m not sure if it can be done but I get the feeling that it shouldn’t be done, unless the window gets created with real scrollbars. -

Wow, thanks for all that work - I hope you found it interesting at least. No worries on my part, I figured it was something obvious I was missing or going to be something very hard. Turned out to be the latter, so I can live with it.
Thanks again!
Cheers.
-
I hope you found it interesting at least
That’s for sure. To be honest I wasn’t fully aware that there are two,
even three types, of scrollbars. The one, which I call real scrollbars,
the one which do get automatically added to a window when this has
been created using WS_HSCROLL or WS_WSCROLL style and userdefined
ones. And that all of them have certain different abilities and need to be treated differently.
So yes, it was fun :-) -
