return the absolute value. Instead, very often QxConst.CORE_AUTO is
returned. Why doesn't these functions calculate the absolute value and
then return it instead? It is difficult to do maths on constants not
resolving in the expression or every time call a separate function to
calculate it when these getters are used. Is this really what is
intended behaviour?
getHeight and getWidth return the values given by the application
programmer. The width and height specified here are the size the widget
should have.
I know this, but I wanted to put light on it.
If you want the current width and height of a widget, use getBoxWidth
and getBoxHeight instead.
I know this too.
The real width depends on the layout and the size the parent widget has.
Which means: if you resize the parent width, the real width changes, but
the width specified by setWidth stays the same.
I know this too.
Your explanation was a good one. The question is still unanswered:
"...intended behaviour?". Then probably answered with a yes.
I think Hugh or you or someone else could put it in the documentation.
This is actually not straightforward, that is why I think it is useful
to document for newcomers.
Width and Height are just normal properties. I think this is already
explained in our property documentation. We should document this if this
would return something computed, but this way it just behaves like any
other property in qooxdoo. And yes, this behavior is intended.
