From 689004fa098a77e837676652eb658ddd5ac88674 Mon Sep 17 00:00:00 2001 From: Geoff Voelker Date: Wed, 3 Sep 1997 01:07:37 +0000 Subject: [PATCH] (SIF_*): Win95 macros defined for NT. (struct tagSCROLLINFO): Win95 struct defined for NT. (vertical_scroll_bar_min_handle, vertical_scroll_bar_top_border, vertical_scroll_bar_bottom_border, last_scroll_bar_drag_pos, Vw32_gab_focus_on_raise, Vw32_capslock_is_shiftlock): New variables. (w32_frame_up_to_date): Block input. (do_line_dance): Use DC while erasing, release at end. (show_mouse_face): Use column and endcolumn calculated at start of loop. (my_create_scrollbar, my_show_window, my_set_window_pos, my_set_focus) [! ATTACH_THREADS]: Send message to window instead of invoking Windows procedure. (x_scroll_bar_create, x_scroll_bar_move, x_scroll_bar_handle_click, x_scroll_bar_report_motion): Use SCROLLINFO for proportional handle. (x_scroll_bar_set_handle): Create proportional sized scroll handle. (w32_set_vertical_scroll_bar): Size handle according to how much is showing in window. (x_scroll_bar_set_report_motion): Use top_range, calculated above. (x_scroll_bar_clear): Hide scroll bar until ready to repaint. (show_scroll_bars): Pass in frame to my_show_window. (w32_read_socket): Distinguish between invisible and obscured frames when handling PAINT messages. Fixup off-by-one calculation for PAINT and SIZE. Pass in new parameter to w32_kbd_mods_to_emacs. Handle WM_DISPLAYCHANGE, WINDOWPOSCHANGED, ACTIVATE, SHOWWINDOW, INITMENU, and ACTIVATEAPP messages. Explicitly check for visibile and obscured frames, and to see if any event should cause a redisplay. (x_display_bar_cursor): Don't check whether frame is updating here. (x_display_cursor): Check it here instead. (x_set_offset) [HAVE_NTGUI]: Don't add border widths. Set NOACTIVATE when setting window position. (x_set_window_size): Fixup off-by-one calculation when setting window position. Mark frame garbaged earlier. Clear mouse highlighting state. (x_focus_on_frame): Set focus by making frame the foreground window. (x_raise_frame): Support frames to be raised without grabbing focus. (x_lower_frame): Set NOACTIVATE flag when setting window position. (x_make_frame_visible, x_make_frame_invisible): Pass in frame to my_show_window. to my_show_window. (x_iconify_frame): Send a MINIMIZE message to the window. (x_wm_set_size_hint): Set font width, line height, border, and scroll bar indexes instead of X and Y unit indexes. (w32_initialize): Set input mode. Use w32_msg_worker instead of windows_msg_worker. Dynamically link proportional scroll bar functions and intialize proportional scroll bar variables. (syms_of_w32term): DEFVAR new variables. (construct_mouse_wheel): New function. Constructs an input event from a WM_MOUSEWHEEL message. (w32_read_socket): Handle WM_MOUSEWHEEL. (w32_read_socket): Pass in new parameter to key_event. Let key_event determine whether key is dead. For MOVE, use x_real_positions to map to client coords. (x_set_mouse_pixel_position): Offset to use client area as origin. --- src/w32term.c | 877 +++++++++++++++++++++++++++++++++++++++----------- 1 file changed, 682 insertions(+), 195 deletions(-) diff --git a/src/w32term.c b/src/w32term.c index 75e53a1216f..a433abc6bb4 100644 --- a/src/w32term.c +++ b/src/w32term.c @@ -27,7 +27,7 @@ Boston, MA 02111-1307, USA. */ #include "charset.h" #include "blockinput.h" -#include +#include "w32term.h" #include "systty.h" #include "systime.h" @@ -95,6 +95,38 @@ HANDLE hWindowsThread = NULL; DWORD dwMainThreadId = 0; HANDLE hMainThread = NULL; +#ifndef SIF_ALL +/* These definitions are new with Windows 95. */ +#define SIF_RANGE 0x0001 +#define SIF_PAGE 0x0002 +#define SIF_POS 0x0004 +#define SIF_DISABLENOSCROLL 0x0008 +#define SIF_TRACKPOS 0x0010 +#define SIF_ALL (SIF_RANGE | SIF_PAGE | SIF_POS | SIF_TRACKPOS) + +typedef struct tagSCROLLINFO +{ + UINT cbSize; + UINT fMask; + int nMin; + int nMax; + UINT nPage; + int nPos; + int nTrackPos; +} SCROLLINFO, FAR *LPSCROLLINFO; +typedef SCROLLINFO CONST FAR *LPCSCROLLINFO; +#endif /* SIF_ALL */ + +/* Dynamic linking to new proportional scroll bar functions. */ +int (PASCAL *pfnSetScrollInfo) (HWND hwnd, int fnBar, LPSCROLLINFO lpsi, BOOL fRedraw); +BOOL (PASCAL *pfnGetScrollInfo) (HWND hwnd, int fnBar, LPSCROLLINFO lpsi); + +int vertical_scroll_bar_min_handle; +int vertical_scroll_bar_top_border; +int vertical_scroll_bar_bottom_border; + +int last_scroll_bar_drag_pos; + /* Mouse movement. */ /* Where the mouse was last time we reported a mouse event. */ @@ -105,6 +137,12 @@ Lisp_Object Vw32_num_mouse_buttons; Lisp_Object Vw32_swap_mouse_buttons; +/* Control whether x_raise_frame also sets input focus. */ +Lisp_Object Vw32_grab_focus_on_raise; + +/* Control whether Caps Lock affects non-ascii characters. */ +Lisp_Object Vw32_capslock_is_shiftlock; + /* The scroll bar in which the last motion event occurred.
