Hi The plugin_if functionality exists, because methods called by plugins run in a different thread context than the gui. Therefore, if you want to gui to act in a certain way, you have to somehow cross the context to achieve whatever you want to do.
Your proposed idea goes in the other direction. You just want the gui to provide you with information about the currently selected frame nr. The approach here would be to add such a functionality in a ui/*.h file, which exposes this information for both gtk and qt interfaces (for now you would need to implement both) and allow anyone to get this information without a thread change. The plugin if functions also by default do not return anything, as they can (at least theoratically) be bound to multiple outputs. the plugin_if_goto_frame could not only trigger the callback for the qt interface, but for a simultanously running gtk interface as well. In reality, this will not happen, but it could. So if you would ask the interface to give you the current frame number and 2-3 different systems are connected, which of the returned values (and it must be returned by a ref-parameter not return value) will you accept? So, to summarize, no, the plugin-if is not the right thing to use, this is a funcionality best exposed in some ui/*.h file, maybe a new one, and an interface the gui implementations provide. regards, Roland On Mon, Jan 4, 2016 at 4:32 PM, Paul Offord <paul.off...@advance7.com> wrote: > Hi, > > > > I’d like to add a new Plugin IF function to get the currently displayed > frame number.
