have no children (in which case they default to 1px thickness & stretch).
This allows to just write <hrule/> instead of <hrule><dummy/></hrule>.
One can still use <hrule><pref-height>3</pref-height></hrule>, of course.
layout.cxx: drop silly do??Box calls for hrule/vrule (yes, I wrote that :-)
or data blocks) from layouter and dialog creator. This is required for
dynamically generated/modified dialogs. Parts in the XML file can be
hidden and turned on by the C++ code. Other hidden parts can be used
as templates that are multiply used. Hidden datablocks can contain
strings that are used in dialog context, that are easier to translate
or modify in the XML file.
- add <vrule>
- allow elements to default to foreground color (black)
- remove redundant if (foo) delete foo;
The rules do currently need a dummy child for the layouter to work correctly,
(<hrule><foo/></hrule>). The goal is to make a simple <hrule/> work.
This is a workaround for an issue where the xml dialogs were shrinking on
subsequent pops.
Andy Ross says:
That looks like it should be fine for a release-time workaround. The
2 pixel border on dialogs is at best a minor feature, and probably
invisible since the sub-frames all have their own padding.
Clearly the right fix would be to find out where the code is getting
confused by the previous layout. In principle, the layout should be
idempotent: if you don't change the layout constraints, it shouldn't
change its layout. There's still a bug in there somewhere.
little larger.
The text widget can now be meaningfully associated with a property; in
PUI, it's "value" isn't the same thing as its label, but we can hack
things to treat them symmetrically.
Commit an experimental "live" property that can be set on widgets to
cause them to update their values every frame. This works great for
text widgets, as above. Note that this synchronization is input-only:
no support is provided (or needed -- the GUI only changes when the
user does something) for writing those properties out every frame.
