Hi. Why is the numeric dimension label not showing up? I start at a
'New' document, draw two points, and put a dimension between them, and
I see no number.

Ah, yes, that fixes it.
But I just discovered a few bugs. First one is that File->New is not
undoable. Why shouldn't it be? That's a better paradigm than to ask
"Are you sure?" Because nearly always

Is there a way to set the dimensions of objects?
I need to draw a bunch of fixed-size holes for switches, but they need
to be at varying rotations.

Hrm. Okay, I can make four angled construction lines, however there

I'm noticing that code in gtkmenus.py which looks like this:

In Interface/Gtk/gtkedit.py/select_motion_notify, _width and _height
are set but not used.
Other than that, it's the same code as in gtkmirror.py/select_motion_notify,
which is the same code as in gtkmodify.py/select_motion_notify.

In Interface/Gtk/gtkmirror.py/get_mirror_line_cb, a variable called
"_got_line" is being set, but is never being used. Should that line
be removed?

Perhaps it should say "Click on the object to mirror"?

Hrm. I've go
I'm trying (as I said before) to design a set of holes for switches,
and I want to use the printed output as a template for cutting holes.
I'll print the output on sticky-back paper, stick it to the panel, and
cut right from the printout.
Not clear to me what "size" paper I should select to get a

I've been looking at the way various components get specified, and
there seems to be a fair amount of overlap. And yet the callback
system of gtk doesn't lend itself well to subroutines. I wonder if it

The O's are points, the crosses are intersections without a point, and
the lines are either construction lines or segments
Art Haas writes:

Still working on that. I'm noticing that there isn't much error
reporting. For example, if you Modify/Mirror something, and then
don't click on a construction line, it doesn't tell you that. Is that
a feature or a bug?

This patch allows you to zoom in and out using the mouse wheel. I
think it has three problems:
1) the scroll increment is too large for a wheel.
2) it's a little hackish to be calling a menu item (but I wanted the
patch to be short).
3) The scrolling should also pan at the same time so
Should menus be created via tables? I suggest this because it will
reduce the amount of code that people need to read. The menu creation
code is very structured. The reason not to do it is because some day
a menu entry (e.g. a "Recent Files" menu) may need to be computed
rather than static.

When you print something with dimensions, it appears as if the text of
the dimensions is being printed twice: once as a TextBlock, and again
as a DimString.

What ARE you talking about?? If a license is open source, it's
