💖 XmDropSiteRegister 💖

okay bestie, gather round, because we're talking about XmDropSiteRegister from the library call girlies — a Drag and Drop function that literally identifies a drop site and assigns the resources that specify its behavior. no cap. 🎀

✨ NAME ✨

XmDropSiteRegister — a Drag and Drop function that identifies a drop site and assigns resources that specify its behavior 🦋

---

✨ SYNOPSIS ✨

#include <Xm/DragDrop.h>
void XmDropSiteRegister(
Widget widget,
ArgList arglist,
Cardinal argcount);

---

✨ DESCRIPTION ✨

so like, XmDropSiteRegister identifies the widget (or gadget!!) you hand it as a drop site, and it sets the resource values that define that drop site's whole behavior. main character energy fr fr. 👑

and here's the cute part: for any resources you didn't specify in the argument list, the routine just assigns default values. it's giving "we got you, don't stress." 💅

⚠️ heads up bestie: the toolkit generates a warning message if a drop site gets registered with XmNdropSiteActivity set to XmDROP_SITE_ACTIVE and the XmNdropProc resource is NULL. so like… don't do that. 😭

also, nesting rules, because of course there are nesting rules:

• if the drop site is a descendant of a widget that's registered as a drop site, then the XmNdropSiteType resource of the ancestor drop site must be specified as XmDROP_SITE_COMPOSITE.
• the ancestor must be registered before the descendant. order matters, no skipping. 🫶
• the drop site gets stacked above all other sibling drop sites already registered. iconic, honestly. ✨

---

🌸 the arguments 🌸

• widget — specifies the ID of the widget to be registered.
• arglist — specifies the argument list.
• argcount — specifies the number of attribute/value pairs in the argument list (arglist).
