From 90100bbd45be8e3bc45f258a32a24f433cadbd70 Mon Sep 17 00:00:00 2001 From: Michael Drake Date: Tue, 11 Apr 2017 16:03:23 +0100 Subject: GTK: Font rendering: Use same pango layout for painting as for measuring. With this change we are consistent about how the pango layout we use is created. Now it always comes from a pango_layout_new() call on a pango context that comes from gdk_pango_context_get(). Previously the pango layout used for painting came from a call to pango_cairo_create_layout(), which required a global called "current_cr" (a cairo drawing context), which is only valid during redraw (painting). Since it was only valid during painting, this source could not be used for pango layout creation for the measuring code. --- frontends/gtk/layout_pango.c | 11 ++++------- 1 file changed, 4 insertions(+), 7 deletions(-) (limited to 'frontends/gtk') diff --git a/frontends/gtk/layout_pango.c b/frontends/gtk/layout_pango.c index bad57d684..5276148e4 100644 --- a/frontends/gtk/layout_pango.c +++ b/frontends/gtk/layout_pango.c @@ -226,27 +226,24 @@ nserror nsfont_paint(int x, int y, const char *string, size_t length, const plot_font_style_t *fstyle) { PangoFontDescription *desc; - PangoLayout *layout; PangoLayoutLine *line; if (length == 0) return NSERROR_OK; - layout = pango_cairo_create_layout(current_cr); + nsfont_pango_check(); desc = nsfont_style_to_description(fstyle); - pango_layout_set_font_description(layout, desc); + pango_layout_set_font_description(nsfont_pango_layout, desc); pango_font_description_free(desc); - pango_layout_set_text(layout, string, length); + pango_layout_set_text(nsfont_pango_layout, string, length); - line = pango_layout_get_line_readonly(layout, 0); + line = pango_layout_get_line_readonly(nsfont_pango_layout, 0); cairo_move_to(current_cr, x, y); nsgtk_set_colour(fstyle->foreground); pango_cairo_show_layout_line(current_cr, line); - g_object_unref(layout); - return NSERROR_OK; } -- cgit v1.2.3
