Title: [Solved] TreeView Shift+mwheel don't work
Post by: AlexTP on January 29, 2023, 07:55:55 am

If i place a treeview on a form, and add some items (long lines), Shift+[mouse wheel] don't work. It must scroll horizontally. now it scrolls vertically.

Lazarus 2.3.0 (rev main-2_3-1386-g23b2324f9f) FPC 3.2.3 x86_64-linux-gtk2

Must be a lack of Widget support, if I read your post correctly.

solved. it is missing support of Shift+mwheel in LCL. I added it by my code.
