XMCREATEERRORDIALOG(3)

✨ NAME ✨

okay so bestie, meet XmCreateErrorDialog — she's the MessageBox ErrorDialog convenience creation function 💅 (yes that's the whole name, she's fancy like that)

---

🌸 SYNOPSIS 🌸

#include <Xm/MessageB.h>
Widget XmCreateErrorDialog(
Widget parent,
String name,
ArgList arglist,
Cardinal argcount);

---

🦋 DESCRIPTION 🦋

XmCreateErrorDialog is a convenience creation function — meaning she does a whole bunch of setup for you in one glow-up move ✨ She creates a DialogShell and an unmanaged MessageBox child of that DialogShell. Two for one, no cap 🫶

An ErrorDialog is the one that warns the user about an invalid or potentially dangerous condition 😭 like bestie something is WRONG and she needs you to know.

She comes with:

• a symbol 🎀
• a message 💬
• three buttons 👑

The default symbol is an octagon with a diagonal slash (the universal "no ❌" energy, iconic). The default button labels are OK, Cancel, and Help.

Wanna pop her up? Use XtManageChild — pass the MessageBox as the widget parameter. Wanna pop her back down? XtUnmanageChild. That's it, that's the whole trick 💖

heads up: XmCreateErrorDialog forces the value of the Shell resource XmNallowShellResize to True. Not a suggestion, not a vibe, she just does it.

now the arguments, one by one, because we don't skip ✨

• parent — specifies the parent widget ID 🌱
• name — specifies the name of the created widget 🏷️
• arglist — specifies the argument list 📋
• argcount — specifies the number of attribute/value pairs in the argument list (arglist) 🔢

For a complete definition of MessageBox and its associated resources, go read XmMessageBox(3) — she's the source of truth, periodt 👑

---

💫 RETURN 💫

Returns the MessageBox widget ID 🫶 that's your girl, go manage her.
