[Plplot-devel] non-IPC3 interactive issues with example 14

[Alan W. I. <ir...@be...>]

Hi Phil:

In the same spirit of getting interactive non-IPC3 to work properly as
a model of what should be done for the IPC3 case, please fix the
following non-IPC3 issues that show up for example 14 for the
current master HEAD:

1. Slave GUI is blank (i.e., does not show any plot).

I am pretty sure this issue is likely caused by the same issue
(screwed up processing of events?) that is causing non-IPC3 display
issues for example 1 in locate mode.

2. Slave GUI finishes and disappears even with no action taken
by the user.

I recently analyzed the cause of this situation in detail.  For all
other interactive devices core coincides with viewer so when the
viewer pauses at page end waiting for the user to hit the enter key
the core automatically pauses as well.  And that assumption is
fundamental to the way that example 14 works.  So to cure this issue
you have to implement the same scenario for the wxwidgets device so
that when the (separate) master viewer pauses at page end, the master
core must be forced to pause as well.
