From: John Darrington Date: Sun, 9 May 2010 10:43:34 +0000 (+0200) Subject: First attempt at a psppire print dialog. X-Git-Tag: v0.7.5~31 X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7d1a2df842bd96a71c3d3b0ce26305e233ab37ac;p=pspp-builds.git First attempt at a psppire print dialog. It basically seems to work, but there are some issues with headers, and charts are not getting rendered for some reason. --- diff --git a/src/ui/gui/output-viewer.glade b/src/ui/gui/output-viewer.glade index dfc2663f..f2d5c024 100644 --- a/src/ui/gui/output-viewer.glade +++ b/src/ui/gui/output-viewer.glade @@ -32,6 +32,13 @@ True + + + True + _Print + True + + diff --git a/src/ui/gui/psppire-output-window.c b/src/ui/gui/psppire-output-window.c index 440df86a..02d4b254 100644 --- a/src/ui/gui/psppire-output-window.c +++ b/src/ui/gui/psppire-output-window.c @@ -110,6 +110,8 @@ psppire_output_window_dispose (GObject *obj) viewer->items = NULL;
