Re: positioning the control panel window

[Sven Thommesen]

OK, here's what I've done in my program (I have a huge ObserverSwarm by
now, and my app is in that peculiar state where it dumps core rather than
do anything useful, so I had to dig a bit.)

Data defined in ObserverSwarm.h:

ButtonPanel *cpWidget;
id               ppdMS;
Frame           *pdMS;
ZoomRaster      *worldHeatRaster;
BLTGraph        *unhappyGraph;

In ObserverSwarm.m / buildObjects:

// The control panel:
cpWidget = [controlPanel getPanel];

// Probe displays (as many as needed):
ppdMS = [ProbeDisplayManager createProbeDisplayFor: modelSwarm];
pdMS = [ppdMS getTopLevelFrame];

// Agent-attribute rasters (already created):
worldHeatRaster = [ZoomRaster create: [self getZone]]; // etc. ...

// Graph objects (already created):
unhappyGraph = [BLTGraph create: [self getZone]]; // etc. ...

I have not investigated the use of EZGraph objects with this.

Finally, if ObserverSwarm.m / placeWidgets,
which is called at the end of -buildActions, after my sim has halted a
couple of times to let me fiddle with probe values (yeah, before placement,
unfortunately):

-placeWidgets {

   [ cpWidget        setWindowGeometry: cpStr];
   [ pdMS            setWindowGeometry: msGstr];
   [ worldHeatRaster setWindowGeometry: hrGstr];
   [ unhappyGraph    setWindowGeometry: uhGstr];

return self;
}

Those strings (msGstr) contain valid X geometry strings. It will take a bit
of fiddling to get placement right, especially if you have a virtual
desktop with several widows on it ...

I read those strings in along with the rest of the parameters, since I have
a different screeen layout at work and at home.

The only change to existing Swarm objects needed for this to work should be
adding the 'getTopLevelFrame' method to SimpleProbeDisplay and
CompleteProbeDisplay. All this method has to do is to 'return topLevel'.

Hope this works!
