XMDATAFIELDSETSELECTION(3)

💖 XmDataFieldSetSelection — the library call that claims the primary selection 💖

okay bestie, welcome to XmDataFieldSetSelection(3), a <cyan>library call</cyan> from the Xm/DataField universe. it's giving "I'm gonna take ownership of your highlighted text and I'm gonna be dramatic about it" energy, and honestly? iconic. 🎀

✨ NAME ✨

XmDataFieldSetSelection — a DataField function that sets the primary selection of the text. no cap, that's literally its whole job description and it ate. 💅

---

🌸 SYNOPSIS 🌸

#include <Xm/DataF.h>
void XmDataFieldSetSelection(
Widget widget,
XmTextPosition first,
XmTextPosition last,
Time time);

yes she takes four args and returns absolutely nothing (void, periodt). she does the work and she doesn't need to hand you a receipt. 🫶

🦋 DESCRIPTION 🦋

so here's the tea, bestie: XmDataFieldSetSelection sets the primary selection of the text in the widget. like, THE primary selection. the one everybody fights over. she's the main character of your clipboard-adjacent life rn. ✨

and she does not stop there, because why would she:

• she also sets the insertion cursor position to the last position of the selection 👑
• and she calls the widget's XmNmotionVerifyCallback callbacks 📞

also, XmDataFieldSetSelection always generates an XmNgainPrimaryCallback — unless it fails to take ownership of the primary text selection. so if she fumbles the bag, no callback for you. 💀 that's the one exception and you need to know it.

now let's do the args, one by one, because we respect the args in this house:

• widget — specifies the DataField widget ID. this is the lil guy you're doing all of this to. 🥺
• first — marks the first character position of the text to be selected. the opening act. 🎬
• last — marks the last position of the text to be selected. the grand finale. 🌟
• time — specifies the time at which the selection value is desired. it should be the same as the time of the event that triggered this request. one source of a valid time stamp is the function XtLastTimestampProcessed. so like, don't just make up a time, bestie, grab it from the actual event. 🙈

lowkey important: that time thing isn't a vibe, it's a requirement — it should match the event's time. one valid source is XtLastTimestampProcessed. ✨

and if you want the complete definition of DataField and all its associated resources, go read XmDataField(3). it's the extended lore. 📚
