chooseColor(3pm)

✨ chooseColor — the Tk::chooseColor manual page, bestie edition ✨

okay so picture this: it's Tk::chooseColor, it lives in section 3pm (User Contributed Perl Documentation, iykyk), and it's about to make picking a color the most fun you've had all day. 🎨💖

🌸 NAME 🌸

Tk::chooseColor — pops up a dialog box for the user to select a color. 💅

That's it. That's the whole job. She pops up, you pick a color, she's done. Iconic behavior honestly.

---

🦋 SYNOPSIS 🦋

$color = $widget->chooseColor?(-option=>value, ...)?;

yes bestie, those question marks are literally in the synopsis, do not come for me, that's just how it's written. ✨

---

💜 DESCRIPTION 💜

So here's the tea. ☕ The method chooseColor is implemented as a perl wrapper on the core tk "command" tk_chooseColor, and $widget gets passed as the argument to the hidden -parent option. Sneaky? A little. Effective? Extremely. 👑

And the implementation of the internal tk_chooseColor is platform specific — on Win32 it's a native dialog (very demure, very native 💅), and on UNIX/X11 it's implemented in terms of Tk::ColorEditor. So like, same vibe, different backstage crew. 🧚

The chooseColor method pops up a dialog box for the user to select a color. And these option-value pairs are possible as command line arguments:

• -initialcolor=>color — specifies the color to display in the color dialog when it pops up. 🎀 The color must be in a form acceptable to the Tk_GetColor function. No random vibes-based color names, bestie, it has to actually parse. ✨
• -parent=>$widget — makes $widget the logical parent of the color dialog. 👑 The color dialog is displayed on top of its parent window. main character energy, front and center, as she deserves.
• -title=>titleString — specifies a string to display as the title of the dialog box. 🎀 If this option is not specified, then a default title will be displayed. So you can name her or let the universe name her, both valid.

Now the important part, no cap:

If the user selects a color, tk_chooseColor will return the name of the color in a form acceptable to Tk_GetColor. If the user cancels the operation, the command will return undef. 😭

So like, always check for undef before you go configuring stuff, bestie, or you WILL be out here configuring your widget to the literal concept of nothing. 💀

🎀 EXAMPLE 🎀

$widget->configure(-fg => $parent->chooseColor(-initialcolor => 'gray',
                                               -title => "Choose color"));

look at her go. 🫶 initial color 'gray', title "Choose color", and the whole thing feeding straight into -fg. Ate. No crumbs. 🔥
