From 764703bf19090fbf0f6502f290405f723e37d078 Mon Sep 17 00:00:00 2001 From: Jim Blandy Date: Thu, 24 Dec 1992 06:19:31 +0000 Subject: * frame.h (struct frame): New fields `can_have_scrollbars' and `has_vertical_scrollbars'. (FRAME_CAN_HAVE_SCROLLBARS, FRAME_HAS_VERTICAL_SCROLLBARS): New accessors, for both the MULTI_FRAME and non-MULTI_FRAME. (VERTICAL_SCROLLBAR_WIDTH, WINDOW_VERTICAL_SCROLLBAR, WINDOW_VERTICAL_SCROLLBAR_COLUMN, WINDOW_VERTICAL_SCROLLBAR_HEIGHT): New macros. * window.h (struct window): New field `vertical_scrollbar'. * xterm.h (struct x_display): vertical_scrollbars, judge_timestamp, vertical_scrollbar_extra: New fields. (struct scrollbar): New struct. (VERTICAL_SCROLLBAR_PIXEL_WIDTH, VERTICAL_SCROLLBAR_PIXEL_HEIGHT, VERTICAL_SCROLLBAR_LEFT_BORDER, VERTICAL_SCROLLBAR_RIGHT_BORDER, VERTICAL_SCROLLBAR_TOP_BORDER, VERTICAL_SCROLLBAR_BOTTOM_BORDER, CHAR_TO_PIXEL_WIDTH, CHAR_TO_PIXEL_HEIGHT, PIXEL_TO_CHAR_WIDTH, PIXEL_TO_CHAR_HEIGHT): New accessors and macros. * frame.c (make_frame): Initialize the `can_have_scrollbars' and `has_vertical_scrollbars' fields of the frame. * term.c (term_init): Note that TERMCAP terminals don't support scrollbars. (mouse_position_hook): Document new args. (set_vertical_scrollbar_hook, condemn_scrollbars_hook, redeem_scrollbar_hook, judge_scrollbars_hook): New hooks. * termhooks.h: Declare and document them. (enum scrollbar_part): New type. (struct input_event): Describe the new form of the scrollbar_click event type. Change `part' from a Lisp_Object to an enum scrollbar_part. Add a new field `scrollbar'. * keyboard.c (kbd_buffer_get_event): Pass appropriate new parameters to *mouse_position_hook, and make_lispy_movement. * xfns.c (x_set_vertical_scrollbar): New function. (x_figure_window_size): Use new macros to calculate frame size. (Fx_create_frame): Note that X Windows frames do support scroll bars. Default to "yes". * xterm.c: #include and "window.h". (x_vertical_scrollbar_cursor): New variable. (x_term_init): Initialize it. (last_mouse_bar, last_mouse_bar_frame, last_mouse_part, last_mouse_scroll_range_start, last_mouse_scroll_range_end): New variables. (XTmouse_position): Use them to return scrollbar movement events. Take new arguments, for that purpose. (x_window_to_scrollbar, x_scrollbar_create, x_scrollbar_set_handle, x_scrollbar_remove, x_scrollbar_move, XTset_scrollbar, XTcondemn_scrollbars, XTredeem_scrollbar, XTjudge_scrollbars, x_scrollbar_expose, x_scrollbar_background_expose, x_scrollbar_handle_click, x_scrollbar_handle_motion): New functions to implement scrollbars. (x_term_init): Set the termhooks.h hooks to point to them. (x_set_window_size): Use new macros to calculate frame size. Set vertical_scrollbar_extra field. (x_make_frame_visible): Use the frame accessor FRAME_HAS_VERTICAL_SCROLLBARS to decide if we need to map the frame's subwindows as well. (XTread_socket): Use new size-calculation macros from xterm.h when processing ConfigureNotify events. (x_wm_set_size_hint): Use PIXEL_TO_CHAR_WIDTH and PIXEL_TO_CHAR_HEIGHT macros. * ymakefile (xdisp.o): This now depends on termhooks.h. (xterm.o): This now depends on window.h. * xterm.h (struct x_display): Delete v_scrollbar, v_thumbup, v_thumbdown, v_slider, h_scrollbar, h_thumbup, h_thumbdown, h_slider, v_scrollbar_width, h_scrollbar_height fields. * keyboard.c (Qvscrollbar_part, Qvslider_part, Qvthumbup_part, Qvthumbdown_part, Qhscrollbar_part, Qhslider_part, Qhthumbup_part, Qhthumbdown_part, Qscrollbar_click): Deleted; part of an obsolete interface. (head_table): Removed from here as well. (syms_of_keyboard): And here. * keyboard.h: And here. (POSN_SCROLLBAR_BUTTON): Removed. * xscrollbar.h: File removed - no longer necessary. * xfns.c: Don't #include it any more. (Qhorizontal_scroll_bar, Qvertical_scroll_bar): Deleted. (syms_of_xfns): Don't initialize or staticpro them. (gray_bits): Salvaged from xscrollbar.h. (x_window_to_scrollbar): Deleted. (x_set_horizontal_scrollbar): Deleted. (enum x_frame_parm, x_frame_parms): Remove references to x_set_horizontal_scrollbar. (x_set_foreground_color, x_set_background_color, x_set_border_pixel): Remove special code to support scrollbars. (Fx_create_frame): Remove old scrollbar setup code. (install_vertical_scrollbar, install_horizontal_scrollbar, adjust_scrollbars, x_resize_scrollbars): Deleted. * xterm.c (construct_mouse_click): This doesn't need to take care of scrollbar clicks anymore. (XTread_socket): Remove old code to support scrollbars. Call new functions instead for events which occur in scrollbar windows. (XTupdate_end): Remove call to adjust_scrollbars; the main redisplay code takes care of that now. (enum window_type): Deleted. * ymakefile: Note that xfns.o no longer depends on xscrollbar.h. * xfns.c (syms_of_xfns): Delete defvars for x_mouse_x and x_mouse_y. That interface hasn't been live for years. (x_mouse_x, x_mouse_y): Delete these variables. * xfns.c (Fx_create_frame): Don't initialize the wm_hints field here. (x_window): Do it here, along with all the similar stuff. It's a pain to remember that you can't assign to FRAME->visible. Let's change all references to the `visible' member of struct frame to use the accessor macros, and then write a setter for the `visible' field that does the right thing. * frame.h (FRAME_VISIBLE_P): Make this not an l-value. (FRAME_SET_VISIBLE): New macro. * frame.c (make_terminal_frame, Fdelete_frame): Use FRAME_SET_VISIBLE. (Fframe_visible_p, Fvisible_frame_list): Use FRAME_VISIBLE_P and FRAME_ICONIFIED_P. * dispnew.c (Fredraw_display): Use the FRAME_VISIBLE_P and FRAME_GARBAGED_P accessors. * xdisp.c (redisplay): Use the FRAME_VISIBLE_P accessor. * xfns.c (x_set_foreground_color, x_set_background_color, x_set_cursor_color, x_set_border_pixel, x_set_icon_type): Use the FRAME_VISIBLE_P accessor. (Fx_create_frame): Use FRAME_SET_VISIBILITY. * xterm.c (clear_cursor, x_display_bar_cursor, x_display_box_cursor): Use FRAME_SET_VISIBILITY. --- src/xfns.c | 903 +++---------------------------------------------------------- 1 file changed, 44 insertions(+), 859 deletions(-) (limited to 'src/xfns.c') diff --git a/src/xfns.c b/src/xfns.c index ef09ffaefbf..d0826835d06 100644 --- a/src/xfns.c +++ b/src/xfns.c @@ -32,7 +32,6 @@ the Free Software Foundation, 675 Mass Ave, Cambridge, MA 02139, USA. */ #include "window.h" #include "buffer.h" #include "dispextern.h" -#include "xscrollbar.h" #include "keyboard.h" #ifdef HAVE_X_WINDOWS @@ -177,7 +176,7 @@ extern Atom Xatom_wm_window_moved; /* When the WM moves us. */ #else /* X10 */ -/* Default size of an Emacs window without scroll bar. */ +/* Default size of an Emacs window. */ static char *default_window = "=80x24+0+0"; #define MAXICID 80 @@ -235,7 +234,6 @@ Lisp_Object Qcursor_color; Lisp_Object Qfont; Lisp_Object Qforeground_color; Lisp_Object Qgeometry; -Lisp_Object Qhorizontal_scroll_bar; Lisp_Object Qicon_left; Lisp_Object Qicon_top; Lisp_Object Qicon_type; @@ -248,7 +246,6 @@ Lisp_Object Qsuppress_icon; Lisp_Object Qsuppress_initial_map; Lisp_Object Qtop; Lisp_Object Qundefined_color; -Lisp_Object Qvertical_scroll_bar; Lisp_Object Qwindow_id; Lisp_Object Qx_frame_parameter; @@ -263,6 +260,14 @@ extern Lisp_Object Vglobal_mouse_map; /* Points to table of defined typefaces. */ struct face *x_face_table[MAX_FACES_AND_GLYPHS]; + +static char gray_bits[] = + { + 0x55, 0x55, 0xaa, 0xaa, 0x55, 0x55, 0xaa, 0xaa, + 0x55, 0x55, 0xaa, 0xaa, 0x55, 0x55, 0xaa, 0xaa, + 0x55, 0x55, 0xaa, 0xaa, 0x55, 0x55, 0xaa, 0xaa, + 0x55, 0x55, 0xaa, 0xaa, 0x55, 0x55, 0xaa, 0xaa + }; /* Return the Emacs frame-object corresponding to an X window.
