XMADDTOPOSTFROMLIST(3)

XmAddToPostFromList 💖

okay bestie, so this one is a library call from the Xm crew — it lives in section 3 of the manual, so you already know it's a C function you call from your code, not some shell thing you type at a prompt. and honestly? she's a RowColumn function that makes a menu accessible from more than one widget. that's the whole gig. one menu, many homes. main character menu energy, fr fr. 👑

✨ NAME ✨

XmAddToPostFromList — a RowColumn function that makes a menu accessible from more than one widget 🎀

---

🦋 SYNOPSIS 🦋

#include <Xm/RowColumn.h>

void XmAddToPostFromList(
Widget menu,
Widget post_from_widget);

like, she returns void. nothing back. no little receipt, no error code, just vibes and side effects. 💅

🌸 DESCRIPTION 🌸

so XmAddToPostFromList makes a menu accessible from more than one widget. that's it, that's the thesis. 🫶

here's the tea: after a menu is once created, this function may be used to make that menu accessible from a second widget. and then? the process may be repeated indefinitely. like, not me adding a third widget, and a fourth, and a fifth — it literally never has to stop, bestie. 🔥

in other words, where an application would use XmCreatePopupMenu or XmCreatePulldownMenu or their equivalent to create a new menu identical to one that already exists, it can use this function to reuse that earlier menu instead. no duplicate menus. no copy-paste menu crime. we love a sustainable queen. 🌈

now the deets depend on what kind of menu you're working with, and this part matters so pay attention:

• if menu refers to a Popup menu, then the post_from_widget widget can now pop up the specified menu. the actual posting of the menu occurs as it always does — either through an event handler, or the automatic popup menu support (see the XmRowColumn(3) reference page). so like, this function doesn't change how it pops, just who can pop it. ✨
• if menu refers to a Pulldown menu, its ID is placed in the XmNsubMenuId resource of the specified post_from_widget. and in this case, post_from_widget must be either a CascadeButton or a CascadeButtonGadget. no exceptions, no negotiating, that's the rule. 🚨

⚠️ important note, bestie: this function manipulates the internal structures themselves, not a copy of them. so like, it's not making you a cute lil duplicate to play with — it's reaching into the real thing. iykyk. 💀

🎀 the arguments 🎀

• menu — Specifies the ID of the RowColumn widget containing the menu (Popup or Pulldown) to be made accessible from the widget. 👑
• post_from_widget — Specifies the widget ID of the widget which will now be able to post the menu specified by menu. 🫶
