✨ NAME ✨

autoscroll — the way it provides for a scrollbar to be automatically mapped and unmapped as needed 🎀

---

🌸 SYNOPSIS 🌸

package require Tcl

package require autoscroll ?1.1?

::autoscroll::autoscroll scrollbar

::autoscroll::unautoscroll scrollbar

::autoscroll::wrap

::autoscroll::unwrap

---

🦋 DESCRIPTION 🦋

This package lets scrollbars get mapped and unmapped as needed, depending on the size and content of the scrollbars' scrolled widget. slay. but heads up bestie: the scrollbar has to be managed by either pack or grid — other geometry managers are not supported. sorry 💅

When it's managed by pack: any geometry changes made in the scrollbar's parent, between the time a scrollbar is unmapped and when it's mapped again, will be lost. and it is an error to destroy any of the scrollbar's siblings while the scrollbar is unmapped. 😭 When it's managed by grid: if anything becomes gridded in the same row and column the scrollbar occupied, it will be replaced by the scrollbar when it gets remapped. not a vibe, just facts.

This package may be used on any scrollbar-like widget, as long as it supports the set subcommand in the same style as scrollbar. If the set subcommand is not used, then this package will have no effect. 💀

🌈 the commands, one by one 🌈

• ::autoscroll::autoscroll scrollbar — Arranges for the already existing scrollbar scrollbar to be mapped and unmapped as needed. glow up time ✨
• ::autoscroll::unautoscroll scrollbar — Returns the named scrollbar to its original static state. putting it back, no notes 🫶
• ::autoscroll::wrap — Arranges for all scrollbars created after this command is run to be automatically mapped and unmapped as needed. every future scrollbar, blessed 👑
• ::autoscroll::unwrap — Turns off the automatic autoscrolling of all new scrollbars. Does not effect existing scrollbars — like, the ones already out there keep doing their thing. 🙈

and here's the little example that lives right here, exactly as it is:

text .t -yscrollcommand ".scrolly set"
scrollbar .scrolly -orient v -command ".t yview"
pack .scrolly -side right -fill y
pack .t -side left -fill both -expand 1
::autoscroll::autoscroll .scrolly
