@Alan yes, git is really good for these things, I forgot about that.
I did git checkout 67ef7be48217c098ae49bb893df5e170c3eccc2c make VERBOSE=1 test_wxPLplotDemo &Phil hmm, still some issues. Good thing I decided to try on all platforms because I was almost going to shout success after trying the 2 ubuntus and debian (that have wxwidgets 3.0) but on CentOS the Yield() has no effect (don't know if it's because is wxWidgets 3.1) So, it happens that I had a similar problem some weeks ago, the problem was that my wxWidgets app (a client) must read some data from a socket on a server and potentially this can take minutes. Initially I did the reading on the socket on the main window frame. But the reading blocks all the GUI, it's not even possible to exit the program, so I started searching for a way to avoid the blocking, and I found the Yield() function on their docs. However it had no effect at all :-) So, my next step was to use a separate thread as explained in their examples. It's good that wxWidgets has its own thread API. This makes the code much more complex, specially the way one thread communicates with the other, but works like a charm. Since my goal was to detect when one task was finished , it may be possible to do something similar here. I'll post on my next email the example I followed. here it goes the results ubuntu, debian, a plot shows 20:53:09: Debug: wxPLplotwindow::wxPLplotwindow 20:53:09: Debug: frame->Create 20:53:09: Debug: wxPLplotwindow::OnCreate 20:53:09: Debug: plD_init_wxwidgets(): enter 20:53:09: Debug: wxPLDevice(): enter 20:53:09: Debug: wxPLDevice(): gc done 20:53:09: Debug: wxPLDevice(): m_interactiveTextGcdc done 20:53:09: Debug: wxPLDevice(): SetDC done 20:53:09: Debug: wxPLDevice(): leave 20:53:09: Debug: plD_init_wxwidgets(): leave 20:53:09: Debug: Plot() centOS, here we get a window with no plot, see the NULL below 21:01:37: Debug: wxPLplotwindow::wxPLplotwindow 21:01:37: Debug: frame->Create 21:01:37: Debug: pls NULL 21:01:37: Debug: wxPLplotwindow::OnCreate 21:01:37: Debug: plD_init_wxwidgets(): enter 21:01:37: Debug: wxPLDevice(): enter 21:01:37: Debug: wxPLDevice(): gc done 21:01:37: Debug: wxPLDevice(): m_interactiveTextGcdc done 21:01:37: Debug: wxPLDevice(): SetDC done 21:01:37: Debug: wxPLDevice(): leave 21:01:37: Debug: plD_init_wxwidgets(): leave ----- Original Message ----- From: "Alan W.
