getstring(3tk)

💖 getstring — a whole string dialog, bestie 💖

okay so this is the getstring page from the tklib manual, section 3tk. it's giving "tiny Tcl package that pops up a little box and asks u for a string." slay. let's get into it ✨

✨ NAME ✨

getstring — a string dialog 🎀

---

🌸 SYNOPSIS 🌸

package require Tcl 8.4

package require getstring ?0.1?

::getstring::tk_getString pathName variable text ?options?

so first u need Tcl 8.4 or better (no cap, it's required fr), then u pull in the getstring package itself — version 0.1 is optional in that ?0.1? way, iykyk 💅 — and then the main character: ::getstring::tk_getString.

---

🦋 DESCRIPTION 🦋

this package hands u a dialog made of three little things: an Entry, an OK button, and a Cancel button. that's the whole vibe. simple, iconic, does exactly what it says 🫶

💜 ::getstring::tk_getString pathName variable text ?options?

this makes a dialog that prompts the user with text, asking them to type in a string. whatever they typed into the entry gets dropped into variable the moment the dialog closes. and the command itself returns a boolean — it tells u whether the user hit OK or not. true = they said yes bestie, false = they dipped 😭

about the placement, and this part is important: if u don't pass -geometry, the dialog gets centered inside its parent toplevel — unless its parent is ., in which case it gets centered on the screen instead. little detail, big difference 🌈

here are the options, all of them, don't skip:

• -title — the title option. the manpage lists it and then just… moves on 🙈 so that's what we're working with, bestie.
• -allowempty — a boolean argument saying whether the dialog should accept an empty entry. so like, can they submit nothing? u decide.
• -entryoptions — just passes its arguments straight through to the entry widget. this is genuinely valuable, ngl, because it lets u do extra validation using the Entry widget's validation hooks 🔥
• -geometry — specifies the geometry of the window ✨

---

⭐ EXAMPLE ⭐

package require getstring
namespace import getstring::*

if {[tk_getString .gs text "Feed me a string please:"]} {
    puts "user entered: $text"
}

see how it works? if the boolean comes back true, u print what they typed. if they cancelled, u don't. main character energy fr 💅
