[SOLVED] ShellTreeView.tvoAllowMultiSelect half-working lazarus / 39-Graphics ---------------------------------------------------------------------- jipété · 2024-09-29 07:08 Hi, In a ShellTreeView with tvoAllowMultiselect checked, the Ctrl-Click works as expected, as usual, but the Shift-Click doesn't at all. By the way, the little help located at the bottom of the Objects' Inspector is half wrong : Allows selection of several tree-items, e.g. using Ctrl+click [OK] and Shift+click [not working]. Of course I've checked msControlSelect and msShiftSelect in MultiSelectStyle. Edit : but I discovered that playing with msControlSelect and msShiftSelect unselect tvoAllowMultiselect.  Reselected it and everything's working. I apologize for the inconvenience (and I cannot delete this topic, dunno why). Linux Debian 11.9 GTK 2.8 FPC 3.2.2 Laz 3.4 Regards,
