Re: Vincent_ GSOC2012: Dialog improvements

Hi Vincent,

Thanks very much for your interest in abiword and your screen shot.
AbiWord presently has a feature in it's backend that allows the width
of a textbox to specified but the height of the text box is then
determined via the amount of text in the text box.

The project would be to enable the user to actually USE this feature
by exposing it in the UI. At present abiword successly imports
textboxes from Open Office documents with this feature but does not
allow users to define it or change it from within the abiword User
Interface.

If AbiWord sees that the the frame property "frame-expand-height"
defined to be non-null it has behaviour.

Cheers

Martin
