From: John Darrington Date: Mon, 6 Apr 2009 11:07:30 +0000 (+0800) Subject: Added a cell-padding parameter to the sheet. X-Git-Tag: v0.7.3~176^2~1 X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1eb005826d07b540f8595c6ffab0781dea9e5f6b;p=pspp-builds.git Added a cell-padding parameter to the sheet. Added a cell-padding paramter of type GtkBorder which specifies the space between a cell's contents and the border. The text is no longer squashed right up against the left hand edge. --- diff --git a/lib/gtk-contrib/psppire-sheet.c b/lib/gtk-contrib/psppire-sheet.c index 4119037d..33e7b47a 100644 --- a/lib/gtk-contrib/psppire-sheet.c +++ b/lib/gtk-contrib/psppire-sheet.c @@ -699,6 +699,7 @@ enum PROP_0, PROP_VAXIS, PROP_HAXIS, + PROP_CELL_PADDING, PROP_MODEL };
