source/winapi/control.c * hwg_DarkGroupProc(): WM_ERASEBKGND no longer fills the whole group box. The group box is above its siblings in the Z-order and is WS_EX_TRANSPARENT, so it was painted after them and wiped out owner-draw SAYs placed inside it (they showed once, then went black). Only the frame band is erased now. * source/winapi/hcontrol.prg * HStatic:Paint(): in dark mode a bordered SAY without BACKCOLOR uses the edit palette, soft white text and a grey border. BACKCOLOR and TEXTCOLOR given by the program still take precedence. * HGroup:New(): added WS_CLIPSIBLINGS. * source/winapi/hcwindow.prg * onCtlColor(): in dark mode HSTATIC/HLINE now honor TEXTCOLOR and BACKCOLOR given by the program (the theme palette is only the default). + Added ContrastColor() to pick black/white text when only BACKCOLOR is given.

source\winapi\dialog.c: Added Owner-Draw menu support inside dialogs. * Added WM_MEASUREITEM and WM_DRAWITEM handling in both s_ModalDlgProc and s_DlgProc. * Delegated rendering to hwg_OnMenuMeasureItem() and hwg_OnMenuDrawItem() from menu_c.c. * source/winapi/menu_c.c ! Owner-draw menus: submenu arrow now drawn with the item text color (visible in Dark Mode) and the system arrow is clipped out. ! hwg_OnMenuDrawItem(): owner HMENU taken from dis->hwndItem instead of wParam (submenu detection and checkmark state were failing). + Added bSubMenu flag to HWG_MENU_ITEM_OD; menu bar items get no arrow.

utils\bincnt\addbatitem.prg: Fixed critical container corruption on delete. * HBinC:Del() was only blanking the object's name in memory instead of removing it from the internal array. * Added hb_ADel( ::aObjects, n, .T. ) to physically shrink the array. This prevents HBinC:Add() from miscalculating the next object's offset and overwriting the file header when the last item is deleted.

hwgui.hbp + Added {zig}-cflag=-DHWG_ZIG_CFGUARD_STUB * source/winapi/window.c ! Added a stub for __guard_dispatch_icall_dummy, enabled only with HWG_ZIG_CFGUARD_STUB (zig cc, Windows x64). Static linking with zig pulls in mingw_cfguard_support.obj from libmingw32, which references this symbol but nothing defines it: "lld-link: error: undefined symbol: __guard_dispatch_icall_dummy". The stub is the "no Control Flow Guard" dispatcher (jmp *%rax). MSYS2 clang and gcc builds are not affected.

contrib\activex\htmlfunc.c, contrib\qhtm\hwg_qhtm.c, source\common\editor\hcedit_w.c, source\winapi\registry.c: * Replaced _WIN32_WINNT 0x0400/0x400 with #ifndef guard + 0x0A00 (Windows 10) fallback. Eliminates the -Wmacro-redefined warning from Clang/Zig when the command line already defines -D_WIN32_WINNT=0x0A00.

source/winapi/window.c: Fixed owner-draw menu message routing. * Intercepted WM_MEASUREITEM and WM_DRAWITEM in s_MainWndProc, s_FrameWndProc, and s_MDIChildWndProc. * Routed these messages to hwg_OnMenuMeasureItem() and hwg_OnMenuDrawItem() before dispatching to the Harbour ONEVENT. * This fixes the issue where context menus rendered as empty grey bars with default arrows on Windows 10.

source\common\xml\xmlparse.c: Completed unfinished error-offset feature. * Fixed -Wunused-but-set-variable warning by making ulOffset functional and exposing it to Harbour. * Added HBXML_GETERROROFFSET() to return the exact byte position where the XML parsing error occurred. * Added HBXML_GETERRORDESC() to translate internal error codes into human-readable English descriptions. * Added HBXML_GETERRORLINE() to convert the byte offset into line and column numbers for easier debugging. * Reset ulOffset at the beginning of HBXML_GETDOC() to prevent error state leakage between parsing sessions. * samples\xmlparseerror.prg: New sample demonstrating XML error handling. * Added XmlErrorMsg() helper that reports error code, description, byte offset, line, and column in a single message. * Added XmlErrorSnippet() helper that shows the XML content around the error position with a [HERE] marker. * Demonstrates three common failure modes: missing quote on attribute, mismatched closing tag, and unclosed tag.

source\winapi\menu_c.c: Applied global font to all menu levels. * Added hwg_ApplyOwnerDrawToMenu() to recursively apply owner-draw to titles and existing submenus when Hwg_SetMenuFont() is called. * Enforced MFT_OWNERDRAW on submenu titles (MF_POPUP) to ensure they inherit the custom font size. * source\winapi\menu.prg: Global font inheritance. * Added STATIC variables _cGlobalFontFace and _nGlobalFontSize. * Updated Hwg_DefineMenuItem() and Hwg_BeginMenu() to inherit the global font when no explicit FONT clause is provided. * Updated hwg_BuildMenu() to pass font parameters to submenu titles.

source\winapi\menu_c.c: Implemented Owner-Draw menu support for custom fonts and bitmaps. * Added MFT_OWNERDRAW conversion, handling WM_MEASUREITEM and WM_DRAWITEM to render text with custom fonts and sizes. * Added TransparentBlt and DrawState support to render bitmaps, removing background colors and graying out icons on disabled items. * Added native checkmark rendering (DFCS_MENUCHECK) synchronized with the internal owner-draw table and GetMenuState. * Added DT_PREFIX handling to support keyboard accelerators (&). * source\winapi\menu.prg: Updated menu definitions to support Owner-Draw features. * Extended Hwg_DefineMenuItem, Hwg_AddMenuItem, and the internal hwg_BuildMenu to process font attributes and bitmaps. * Added submenu detection using ValType() to navigate nested menus. * Added safe bitmap loading to avoid crashes on missing image files. * include\guilib.ch: Added the FONT clause to the Menu system commands. * MENUITEM and MENUITEMCHECK now accept: [ FONT <cfont> [, <nfontsize> [, <nfontweight> [, <litalic> ] ] ] ]</litalic></nfontweight></nfontsize></cfont> * Usage example: MENUITEM "Open" ID 102 ACTION OpenFile() ; FONT "Segoe UI", 12, 700 BITMAP "open.bmp" * samples\menufont.prg: Added new sample demonstrating custom menu fonts and bitmaps. * Shows how to use Hwg_SetMenuFont() for global defaults. * Demonstrates mixing items with FONT, BITMAP, and checkmarks. * Uses HWG_CHECKMENUITEM() to toggle states dynamically.
