Skinnable scrollbars

Post by bertolino » Sat Apr 17, 2021 8:13 pm

Hello everyone,

I've noticed that regularly, wxWidgets users are looking for a way to change their scrollbar style.
Last year I started something about this, then the time passed, I forgot this piece of code until recently
where I came across one of these articles. So I decided to share what I did in the case it could help (see example below).


It's not a miracle solution, it's not production-ready code, I even do not claim it's a good solution.
But it may help people as a base to do something better.

It is based on the wxScrolled<wxWindow>::SetTargetWindow that is able to redirect scrolling to a given window.

The code is reasonably commented so I guess it can be handled and modified without too much difficulties.
I have tested it under Windows only, using wxWidgets 3.1.

You will find a zip archive of it here ... that includes:
- 1 file for the toy program
- 2 files (cpp and .h) for the scrolled window class
- 2 files (cpp and .h) for the scrollbar class

my_scrolled_window.h explains with a small graphic the way the panels are embedded in each other.

In the main file, a #define among 5 allows to see the scrolled window in different contexts :
- to scroll a panel
- to scroll a toolbar (in this case, horizontal or vertical scroll can be disabled)
- to scroll a dialog

One can tune:
- the scroll direction (horizontal, vertical or both)
- the thumb color, the margin color and the tip color (not sure it's the right terms)
- the size of these items

All the events are not managed but the thumbs work well with the mouse. it still needs some work....
I hope you will enjoy it.

By the way, thanks to the wxWidgets team for such a great tool and thank you to the forum team for their valuable support all year long.

Kind regard,

This is a nice solution to it! A lot of people have wanted a way to customize the scrollbars, so I think this is a very good contribution :)
I've made a custom solution to this as well, but it works in a different way and it's restricted to wxRichTextCtrl. Interesting to see how different your method of implementation was compared to mine.
