looking for a widget like pd's number box

["Rich E" <reakinator gmail com>]

Hi all,

I am a happy user of Miller Puckette's Pure Data (pd) for real-time audio processing, but not too happy with the interface, which uses the tk toolkit.  So, I am working towards developing a similar, but expandable, interface using GTK+.

I was hoping someone could help decide what I have to do to replicate the number box in pd. As far as I can tell from the source, it is created from scratch using tcl scripting commands. It consists of a number entry area and looks very much like the GtkSpinButton, without the arrows on the side.  To change the number with the mouse, you click on the number area and drag the mouse upwards or downwards.  You can also shift-click for finer precision.  

Has anyone seen something like this in gtk, or will I have to write it?  

Just trying to stop duplicated work if that would be the case, and at the same time attempt to get the advice of gtk users with more experience than myself (which isn't much).

regards,
Rich
