You need to provide a layout clause, something like the
following should do:
define pane <my-pane> ()
pane the-text (pane)
make(<label>, label: "hello");
layout (pane)
vertically () pane.the-text end;
end pane <my-pane>;
But, you can just contain the label directly too:
contain(make(<label>, label: "hello"));
All that 'contain' does is to create a frame to wrap up whatever
DUIM object you pass, and then calls start-frame on that frame. It
is a great tool for experimentation. Note that it even works with
menus, toolbars etc.:
contain(make(<menu-box>, items: #["Red", "Green", "Blue"]));
contain(make(<progress-bar>,
value-range: range(from: 0, to: 100),
value: 33));
Hope this helps,
Andy
