Hello,

Does anyone know of any trackbar control which supports multiple thumbs on one single trackbar?

I am looking for a trackbar which supports 2 or 3 thumbs on the same trackbar.

If anyone knows of any such VCL control please do point me to that control's web page/site.

I am using Delhi 10.3 Rio for this particular project.

TIA

Far as I know, there are commercial TMS and DevExpress multi-slider components, a free one (which I often use, with nice options) called MultiSlider, but it's written in C++.

Regarding free Delphi multi-slider, this one may be of interest (a simple one):

Hi

ImageEn does it using a TRulerBox (in ImageEn component folder). You can see an example of it in previews.pas (you need to remove the IEINCLUDEDIALOGIP IFDEF and reopen it to view the form).

Hello,

Thanks for the suggestions.

I finally modified the code of a sample in GR32 to create a slider with three thumbs.

I am using this code at the moment.

TIA
