From 076e902b2c911a9f6c23e620db2813339263902a Mon Sep 17 00:00:00 2001 From: "Owen W. Taylor" Date: Sun, 20 Sep 2009 13:41:13 -0400 Subject: [PATCH] Centralize computations of border and padding into StThemeNode Rather than repeating the computation of borders in many different widget subclasses, add helper functions: st_theme_node_adjust_for_height() st_theme_node_adjust_preferred_width() st_theme_node_adjust_for_width() st_theme_node_adjust_preferred_height() st_theme_node_get_content_box() That are used in get_preferred_width()/get_preferred_height() and allocate() methods to consistently apply the necessary adjustments. This allows removing the StPadding type. Queueing a relayout when the borders/padding change is moved from st_widget_real_style_changed() to the invoking code to allow access to the old StThemeNode for comparison. (Should this be added as a parameter to the signal?) Borders are included in the geometry adjustments, but borders are not yet drawn. https://bugzilla.gnome.org/show_bug.cgi?id=595993 --- src/st/st-bin.c | 91 ++++++-------------- src/st/st-box-layout.c | 172 ++++++++++++++++++++------------------ src/st/st-entry.c | 48 ++++------- src/st/st-label.c | 33 +++----- src/st/st-scroll-bar.c | 74 ++++++++-------- src/st/st-scroll-view.c | 56 ++++++------- src/st/st-theme-node.c | 181 ++++++++++++++++++++++++++++++++++++++++ src/st/st-theme-node.h | 20 +++++ src/st/st-tooltip.c | 61 ++++---------- src/st/st-types.h | 23 ----- src/st/st-widget.c | 72 ++++++---------- src/st/st-widget.h | 2 - 12 files changed, 446 insertions(+), 387 deletions(-) diff --git a/src/st/st-bin.c b/src/st/st-bin.c index f48e735e7..ed00e63b7 100644 --- a/src/st/st-bin.c +++ b/src/st/st-bin.c @@ -198,23 +198,22 @@ st_bin_allocate (ClutterActor *self, if (priv->child) { + StThemeNode *theme_node = st_widget_get_theme_node (ST_WIDGET (self));
