Description Rich Jones 2008-02-22 05:16:23 UTC 
Please describe the problem:
click once anywhere above or below the line in the graph display,
the line will add a point, and snap the line to the point,
but nothing occurs in the image preview.

If you click a second time, a second point is added and the preview updates
Click reset
Now drag the line for the first point, preview works fine.

I tried in linear, same results.
Freehand displays preview correctly.

Steps to reproduce:
1. click curves under colors menu
   dialog appears, channel value, logarithmic mode, preview enabled, and    curve type smooth

2. click once anywhere above or below the line in the graph display,
   the line will add a point, and snap the line to the point,
   but nothing occurs in the image preview.
 
 


Actual results:
The preview of the image does not occur

Expected results:
Immediate changes to the image if the preview option is enabled.

Does this happen every time?
Yes.

This only happens in the stable branch, SVN trunk is not affected.
Comment 2 Sven Neumann 2008-02-25 14:06:16 UTC 
This is now fixed in the stable branch:

	* app/tools/gimpcurvestool.c (curves_graph_events): in the
	button-press handler for smooth curves, recalculate the curve
	before updating the preview. Fixes bug #518012.
