MacroGroup — Pack Resource ID Table (IDR_ constants)
Source File: include/cef_pack_resources.h
Process / Thread Context: Compile-time only (macro definitions).
Purpose: Generated by make_pack_header.py. Defines 962 #define IDR_* numeric constants for resources bundled into the CEF/Chromium resource pack (HTML, CSS, JS, image, JSON, manifest, lottie, flac, etc.). Numeric values are version-specific; use cef_id_for_pack_resource_name() (see cef_id_mappers.h) for version-safe lookups.
Notable Members

Usage Example
cpp
#include "include/cef_pack_resources.h"
#include "include/cef_id_mappers.h"
// Option A: hard-coded numeric value (version-specific).
CefRefPtr<CefResourceBundle> bundle = CefResourceBundle::GetGlobalBundle();
CefRefPtr<CefBinaryValue> license = bundle->GetDataResource(IDR_CEF_LICENSE_TXT);
// Option B: version-safe lookup at runtime.
CEF_DECLARE_PACK_RESOURCE_ID(IDR_CEF_LICENSE_TXT); // file-scope static
CefRefPtr<CefBinaryValue> license2 = bundle->GetDataResource(IDR_CEF_LICENSE_TXT);
// Option C: explicit resolver call.
int idr = cef_id_for_pack_resource_name("IDR_NET_ERROR_HTML");
if (idr != -1) { bundle->GetDataResource(idr); }
