SimulationController don't works

[Sergei Dorofeenko]

For some reason SimulationController's buttons (play, pause, etc.) are disabled in the svn1934 and the indicator panel (with simulation time, etc.) is lacking (see attached figure). In addition, when SimulationController is actived SimulationView is updated only when you click the mouse on it (if the SimulationController is closed, then everything is fine).

I have just checked SVN 1935 and it works ok for me. All buttons are active.

I added lock to omega that makes the buttons inactive during loading simulation (the "[loading]" instead of file name) to avoid crashes, last week.

How do you make it behave in the way as on the figure? It is a bug, yes.

[Sergei Dorofeenko (sergei.dorofeenko)]

Nothing special. Just click on Controller button or type yade.qt.Controller() in the console.

ps. May be important that I use a patch to gui/qt3/GLViewer.cpp because without it Viewer is not works (only black window).

The locking doesn't work for you then at all!

I just installed boost 1.37 (I didn't know it was in repositories for jaunty) and will fix it properly.

The code was written blindly just following the docs as I had 1.34 till now. Sorry.

[Václav Šmilauer (eudoxos)]

Try r1936 please (and no patches of GLViewer! ;-) )

[Sergei Dorofeenko (sergei.dorofeenko)]

Thanks! All work!
