commit 0ce05a04c8df4b391936864cd46a1ed5cbfbdb84
Author: Owen W. Taylor <otaylor fishsoup net>
Date: Sun Sep 20 13:41:13 2009 -0400
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.
