XMDATAFIELDSETSTRING(3)

✨ NAME ✨

XmDataFieldSetString — bestie, this is the DataField function that sets the string value 💅

🌸 SYNOPSIS 🌸

#include <Xm/DataF.h>
void XmDataFieldSetString(
Widget widget,
char * value);

🦋 DESCRIPTION 🦋

Okay so XmDataFieldSetString sets the string value of the DataField widget. That's the whole assignment, and it ate. 👑

But the way it does it? Iconic behaviour. This routine calls the widget's XmNvalueChangedCallback and the verification callbacks — that's either XmNmodifyVerifyCallback or XmNmodifyVerifyCallbackWcs, or both of them if you're feeling extra.

And here's the tea on ordering, because it matters fr fr: if both verification callback lists are registered, the procedures of the XmNmodifyVerifyCallback list are executed first, and the resulting data is then passed to the XmNmodifyVerifyCallbackWcs callbacks. No cap, that's the sequence. 🫶

It also sets the insertion cursor position to the beginning of the string, and calls the widget's XmNmotionVerifyCallback callbacks. So many callbacks, so little time. 😭

• widget — Specifies the DataField widget ID
• value — Specifies the character pointer to the string value and places the string into the text edit window
