From 52cf03a10fcddb3534cc87aff14932f13f85858b Mon Sep 17 00:00:00 2001 From: Geoff Voelker Date: Fri, 3 May 1996 18:45:32 +0000 Subject: [PATCH] (Vwindow_system): Declared. (win32_fill_rect, dumpglyphs, do_line_dance, x_draw_box): Use Get/ReleaseFrameDC. (pixel_to_glyph_coords): Support tty mode. (w32_read_socket): Explicitly use FALSE. Handle WM_PALLETTECHANGED event. (parse_button): Handle mouse button emulation. (my_show_window, my_set_window_pos): New functions. (x_set_offset, x_set_window_size, x_raise_frame, x_lower_frame): Use my_set_window_pos. (x_make_frame_visible, x_iconify_frame): Use my_show_window. (x_draw_box): Don't trim right and bottom. (x_make_frame_visible): Don't invoke SetForgroundWindow. (win32_term_init): Use GetDC directly. Initialize palette and win32_num_mouse_buttons. (win32_update_begin): Regenerate palette if necessary. (x_delete_display): Free palette. (win32_initialize) [ATTACH_THREADS]: Only AttachThreadInput if conditional is defined. --- src/w32term.c | 309 ++++++++++++++++++++++++++++++++++++-------------- 1 file changed, 226 insertions(+), 83 deletions(-) diff --git a/src/w32term.c b/src/w32term.c index 2daa30d96c..3f214a5347 100644 --- a/src/w32term.c +++ b/src/w32term.c @@ -15,8 +15,7 @@ GNU General Public License for more details.
