Using SetVisibleLayers or SetVisibleElements does not change on screen until changing canvas.

[Greg Smith]

In python scripting, when using pcbnew.GetBoard().SetVisibleLayers() or pcbnew.GetBoard().SetVisibleElements(), neither the checkboxes in the LayerManager nor the actually visible layers change in the PCB view. Changing the view from OpenGL and *back* correctly shows both the layers and the checkboxes. Refreshing the wx.Window for the pcbnew window and the LayerManager window does not help the display. Only changing views seems to help.

This greatly affects the usability of [LayerViewSet](https://github.com/HiGregSmith/LayerViewSet).

Call: void PCB_DRAW_PANEL_GAL::SyncLayersVisibility( const BOARD* aBoard )

Cheers,

I agree that this appears to be the solution. How do I call PCB_DRAW_PANEL_GAL::SyncLayersVisibility from python? I can't find where it exists in the python hierarchy.

Perhaps it's not exported. Feel free to submit a patch (I'm not a Python
expert) or ask our Python gurus if they could add this function.

Cheers,

PS. nice feature, this LayerViewSet.

Further testing reveals that this is not yet fixed. KiCommand on github has the function call after each command string and still some lines don't show up until switching canvasses.
