From 841f376a1c2b5dfef22e02696d5ad2ba053ecfbe Mon Sep 17 00:00:00 2001 From: Ton Roosendaal Date: Sun, 21 Dec 2008 11:05:43 +0000 Subject: 2.5 - View3D: added ALT+B clipping operator. Note this needs a call to the new function view3d_operator_needs_opengl(C) to ensure you can use opengl functions. Event handling by default doesn't set opengl per subwindow, it's also forbidden to draw then! We might consider to tag operators that need opengl... - Forgot to include creator.c fix for loading builtin vector font --- .../blender/editors/space_view3d/view3d_select.c | 152 ++++++++++++--------- 1 file changed, 91 insertions(+), 61 deletions(-) (limited to 'source/blender/editors/space_view3d/view3d_select.c') diff --git a/source/blender/editors/space_view3d/view3d_select.c b/source/blender/editors/space_view3d/view3d_select.c index 9d0616d4f54..351dfad4cc5 100644 --- a/source/blender/editors/space_view3d/view3d_select.c +++ b/source/blender/editors/space_view3d/view3d_select.c @@ -1673,14 +1673,12 @@ void ED_VIEW3D_OT_borderselect(wmOperatorType *ot) ot->poll= ED_operator_areaactive;
