Re: Please don't drop support for Curve

[Dov Grobgeld <dov grobgeld gmail com>]

I suggest that you learn how to create your own widget. A widget like GtkCurve is very easy to develop by subclassing one of the canvas widgets, e.g. GooCanvas. Or do it directly through Cairo on a GtkDrawingArea. This is described here:

Hello all,


I've joined up with this list for one single reason: to ask the developers to
re-consider and reverse their decision to deprecate and eventually remove the
Curve widget from GTK+.

Recently, I learnt to create Python scripts, and with the help of Glade, created
a GUI to ImageMagick routines, for my own "proprietary photo editor". The Curve
widget was absolutely central to this endeavour. The only downside is that it is
basic and not very well developed.

To me, the reasons given for this widget being deprecated, that it isn't very
useful and only appeals to a minority of users, sounds disingenuous and hurtful
to the easy usefulness of GTK+. What do you expect users to do in its absence?
Do you really expect users to go breaking their knuckles to try and create a
curve dialog with a drawing area? How could you see such "progress" as anything
but a step backwards?

So please, hear a busy user who has taken the trouble of registering here to
offer feedback: do not drop this essensial component of GTK+, and instead of
deprecating it, continue its development. You can drop Gamma Curve if you like,
which is too idiosyncratic to be of much use. What is needed instead is the
Curve offering point data - the points on the curve that the user creates -
being able to be read and manipulated by other widgets, such as the numerical
scroll boxes. (Rather like the Curves dialog in Photoshop.) And I'm sure there
are other improvements that could be made.

If on the other hand you insist on dropping the Curve, then when the time comes
I guess I'll have to switch to another widget toolset, whichever will still be
offering a Curve interface element. I can't even begin to image how long it
would take me to create the widget manually - it frankly strikes me as an insane
and pointless effort.

Thank you for your attention and best wishes with your continuing good work.
What you have created in GTK+ (and pyGTK) is greatly appreciated and wonderfully
useful.

All the best,

Charlie
