ruby 1.9.3, wxWidgets 2.8.11, wxruby 2.0.1, ubuntu 11.10 x86_64 To get my sizers to update everything in some cases I need to: self.parent.send_size_event Self is a derived class of Wx::ScrolledWindow The scrolledWindow is embedded in an AUI managed pane. While the pane is attached, the parent class is Wx::AuiFrame. At this point I can trigger an event that in turn calls the send_size_event and things are good. If I detach the pane and fire the event that calls the self.parent.send_size_event I get the below error: /wx/accessors.rb:48:in `get_parent'': Error wrapping object; class `wxAuiFloatingFrame'' is not supported in wxRuby (NotImplementedError) I am thinking that the floating frame is a top frame and there isn''t an application parent or I simply (hah) need to implement get_parent in some manner to deal with the size event feedback I want. My current theory is I need to find a proper hook at some level above my embedded window. I am having trouble finding a hook or other method to get around the above fault. I will continue to try and find a wedge into the AuiFloatingFrame but think that route may be beyond my understanding at this time to do some surgery on the SWIG stuff (working on that). Any assistance is very much appreciated. In the meantime I will continue pluggin away at it. If needed, I can whittle down my app to showcase the problem. Have a good one! TK
