I could check that no figure pops up during tests anymore.

Closing report as fixed.

i pushed the following change

switching line 236 from hd = figure (gcf); --> hd = gcf (); as suggested in comment #5.   verified that all tests still pass, no figs pop up, and all demos still work. 

Marking Ready for Test.

The problem is the following construct in dendrogram:

set (0, "defaultfigurevisible", "off");
hf = figure (gcf);

Here `gcf` returns a handle to an invisible figure that is passed to the `figure` function. The latter operation makes the figure visible and gives it keyboard focus, this is the expected behavior.

Replacing `hd = figure (gcf)` by `hd = gcf ()` should do the trick.

on my windows system the fig window appears every time i run the tests. it only comes up with the one in the separate test block mentioned below, not any of the other tests.  if i comment out that test, none of the others create a figure window.

Actually, for me with Octave 6.2.0, Linux, and qt graphics, `test dendrogram' does brings up a window, but only the first time I run it in a session, not subsequent times. I don't know why that is.

for me in windows ( 7.0.1 (hg id: bbf1293bd255)), it does, but only with the qt toolkit. if i switch to fltk or gnuplot, i don't get the plot window. if i switch back to qt, i do.

For me in Linux, `test dendrogram' doesn't open any plot window.

noticed in the recent statistics package release (1.4.3) that when running the test suite dendrogram flashes a figure window.  this was suppressed in other functions by capturing the DefaultFigureVisible setting, turning it off before the test, then restoring the original value after the test. the following test, however, displays despite this being done:

%! set (0, "DefaultFigureVisible", "off");
%! fail ('dendrogram ([1 2 1], "Orientation", "north")', "invalid orientation .*")
%! set (0, "DefaultFigureVisible", visibility_setting);

is it something about the Orientation setting call that causes the figure window to popup? Is there a better way to suppress figure display during tests?
