RE: repaint problem...

Greetings:

I am having very similar troubles.  I figure there must be a simple way to
handle this, but I can't figure it out from the API docs or source code.

I am displaying two data sets in a JTabbedPane:  dataset T is displayed in a
JTable, while dataset P is displayed in a JPlotLayout.  T and P each have
their own tab in the JTabbedPane.  T is the currently selected (visible)
tab.  Now I perform some calculations that update the data in both T and P.
All goes well *except* that the JPlotLayout forces its way to the front and
renders on top of everything.  If I click on the tab for T, this resets the
correct order (i.e., T's JTable becomes visible again), but this is
obviously an unsatisfactory solution.

Is there some simple way to force the JPlotLayout to know its place (and
stay there)?

Thanks in advance -- Mark Flood

Progress of sorts.. if set up a hierarchychanged listener for the plot pane
and do a frame.repaint() it handles it correctly except as follows: if I
manually resize the frame larger, I get the whiteout behavior (even if I do
a frame.repaint in response to the frame's resize event..., if I resize the
frame smaller its fine... once I do a zoom in with the mouse its fine
forever more in all cases...  maybe there is something in the
doublebuffering or repaint manager I need to do to force proper
initialization of the layers?

Im new to java and sgt, but here goes...

Im tying to place a plot like the timeseries plot onto a tabbed panel.  -
having one tab to be the graphic and the other be the tabular data... when I
fire up the application, the demo plot flashes for an instant then 'goes
white'.  I have to zoom in or drag a different frame over the application
window to get the graph to display- or switch between the two tabs . From
then on it works great!. I cant seem to find the right method and the right
place to make the call to get it to display. It is as if the viewable part
of the plot is hidden behind a white screen when it first comes up. If I
force the tab that the graph is on to be the selected tab, and call the
frame.repaint() right after the setvisible its no problem..  but that is the
only scenario that works so far.  Any help greatly appreciated!
