Summary	0001171: Magnifier hangs
Description	Sometimes the magnifier hangs and blinks for about 10-20 seconds on my machine. Most of the time the hanging stops and the magnifier returns to normal state. This happens no matter if anything is displayed in the renderViews.
Steps To Reproduce	Just play with Slicer a little bit, maybe move the mouse over the 3D or Slice views.
Additional Information	I ran the following CTK tests: 17:20:38 daniel@sbia-pc66:~/SLICER/QT_TRUNK/Slicer4-Superbuild/CTK-build/CTK-build$ ctest -R "agnify" -VV UpdateCTestConfiguration from :/Users/daniel/SLICER/QT_TRUNK/Slicer4-Superbuild/CTK-build/CTK-build/DartConfiguration.tcl Parse Config file:/Users/daniel/SLICER/QTTRUNK/Slicer4-Superbuild/CTK-build/CTK-build/DartConfiguration.tcl Add coverage exclude regular expressions.

dpace 2011-06-01 13:36 developer ~0002474	Thanks for the bug report Daniel. Can you please give me some specs of your workstation? I.e. Windows/Linux/Mac, memory/processor. Have you noticed that there is something in particular that appears to trigger the problem, or is it apparently random? I've never seen the behavior on my workstation, but I can try to find another machine that is similar to yours for debugging. Thanks, Danielle

dpace 2011-06-20 12:21 developer ~0002542	The stall seems to be related to the toggle between the 2D-magnify and 3D modes on the ThreeDControlWidget. Unfortunately, I can't reproduce the failure on my machine. Let me create a test for this widget to try to reproduce the behavior. Daniel: Do ctkCrosshairLabelTest1, ctkCrosshairLabelTest2, and ctkVTKMagnifyViewTest1 pass? Can you please try increasing time = 1000 on line 258 of ctkVTKMagnifyViewTest2, and let me know if that test still fails?

haehn 2011-08-02 07:10 developer ~0002646	BTW, Ron confirmed it on his machine which has a similar configuration

fedorov 2011-08-02 16:01 developer ~0002647	I played with layouts, and closed slicer when I had "3 over 3" layout active. After this, each time I would start Slicer, it would go to "3 over 3" layout, quickly start flicker, show spinning ball icon for a while, and crash. After disabling zoom-view, crash is gone. Workaround from Julien to disable zoom-view: Either comment line 74 (q->setDisableMagnification(false);) in qMRMLThreeDViewsControllerWidget Or from python: mainWindow = slicer.util.mainWindow() viewsController = slicer.util.findChildren(mainWindow, 'MRMLThreeDViewsControllerWidget')[0] viewsController.disableMagnification = True

fedorov 2011-08-02 16:01 developer ~0002648	Oh, sorry -- my platform is very similar to Daniel's and Ron's: MacBook Pro, Snow Leopard, Intel i7

finetjul 2011-08-03 10:02 administrator ~0002651 Last edited: 2011-08-03 12:34	Maybe related, ctkCrosshairLabelTest2 is failing on some CTK dashboards: http://my.cdash.org/viewTest.php?onlyfailed&buildid=215910

finetjul 2011-08-10 10:12 administrator ~0002681	From JC on August 3rd 2011: If you add the python line reported by Julien into a file named slicerrc.py located into your home folder, the magnifier will be automatically disabled at startup.

finetjul 2011-08-10 13:37 administrator ~0002686	From Jim on 8/10/2011: Here is my test. I start Slicer in 2x2 layout and move the mouse quickly between the yellow and green viewer. Eventually, Slicer gets behind in the event queue, a spinning beach ball appears, and Slicer may even crash (gdb) where 100 #0 0x00000001211fcd44 in QTextEngine::itemize () 0000001 0x00000001211fe313

finetjul 2011-08-10 13:38 administrator ~0002687	Disabled on mac for now: http://viewvc.slicer.org/viewvc.cgi/Slicer4?view=revision&revision=17705

kikinis 2011-08-15 10:17 developer ~0002711	is still active in mac nightly 8-15

dpace 2011-08-23 08:07 developer ~0002777	If I load an image and mouse around in a single 2D viewer, I don't see updates to the magnification. If I click, then I get the updated zoomed view. Also, if I move from inside a slice viewer to the 3D viewer, the ThreeDViewController correctly switches to the navigation view. But if I go from the 3D viewer to a slice viewer, the magnification view doesn't come up until I click. From this, I suspect that the magnifer may not be getting Enter events on mouse overs, which may be messing up the timer-based looping it does.

kikinis 2011-09-02 04:56 developer ~0002883	this just crashed the slicer nigthly 9-2 mac for me. Can you please completely disable the magnifier until somebody has time to fix this properly?

finetjul 2011-09-06 15:54 administrator ~0002929	Fixed in r17987(and r17988): http://viewvc.slicer.org/viewvc.cgi/Slicer4?view=revision&revision=17987 (http://viewvc.slicer.org/viewvc.cgi/Slicer4?view=revision&revision=17988)

jcfr 2012-05-08 22:46 administrator ~0004217	Since the magnifier is not used anymore in Slicer, will consider that this is issue is closed.
