Hi Phil: I just discovered on Linux that your IPC3 workaround does allow -locate mode for example 1 to work perfectly for mouse clicks. (IPC3 locate mode key hits are not implemented yet.) But I also think that workaround should not be necessary, and the fundamental problem is when I originally implemented IPC3 locate mode I used the non-IPC3 version of wxPlFrame::ReadTransmission to model what the IPC3 version of that routine should do in locate mode, but it turns out that is a flawed model! So it is no wonder that you had to implement a workaround to get locate mode to work at all for the IPC3 case.
Here are the current (master HEAD) problems with locate mode for the non-IPC3 case as demonstrated when I run examples/c/x01c -dev wxwidgets -locate on Linux. 1. The initial wxPLViewer response is always a blank screen. 2. Furthermore, initial blind mouse clicking on the position of viewports 2, 3, and 4 gets no response at all. Blind clicking on the (upper-left) position of viewport 1 does typically get a response (but sometimes only after several clicks), and if I keep clicking eventually the actual plot appears, and then after that clicking on viewports 2, 3, and 4 finally begins to work. 3. In no case have I gotten key hits to work (even though there is code to handle that case for the non-IPC3 version of wxPlFrame::ReadTransmission). My guess is most or all of symptoms 1 and 2 are due to some screwup with the way events are being handled in the non-IPC3 case, and I likely propagated those same problems to the IPC3 side of things when I implemented the IPC3 version of locate mode. I have no explanation as to why hitting keys gets no response (symptom 3) for the non-IPC3 case. In any case, I hope you are willing to fix the above set of non-IPC3 issues because once they are solved I believe I should be able to quickly follow up with a reliable IPC3 variant using your corrected non-IPC3 implementation as a model.
