Python SetSelected() doesn't display until view switched

[Greg Smith]

Windows nightly as of July 31, 2017

Executing the following in Scripting Console:

import pcbnew

for m in pcbnew.GetBoard().GetModules():
 m.GetValue().SetSelected()
 m.GetReference().SetSelected()
 for d in m.GraphicalItems():
  d.SetSelected()

for d in pcbnew.GetBoard().GetDrawings():
 d.SetSelected()

The selected items do not appear in OpenGL view until the view is switch to default and back.

Also, adding DRAWSEGMENTS on the board don't show up until the view is switched.

This also happen in Linux and possibly MacOS and, to a limited extent, in 4.0.6 Stable.

Hi Greg,

For the moment, selection in GAL is not exposed to Python.

You can try using SELECTION_TOOL::select( BOARD_ITEM* aItem ), but there's no guarantee it will work.

Best,
Tom

Tom, OpenGL does seem to recognize. When I switch to default view, then back to OpenGL, the selected items display as selected (brighter than non selected items).

I will also try your suggestion, if I can figure out how to under python.

[Tomasz Wlostowski (twlostow)]

SetSelected() is not sufficient. It looks like we'll need to expose some of the GAL selection APIs to Python.

How about:

pcbnew.[Un]Select (items) -> adds/removes items from the current selection.
pcbnew.SetSelection(items) -> clears the current selection and sets it to (items).
pcbnew.GetSelection -> returns a vector of currently selected items.
pcbnew.ClearSelection (obvious)

FWIW this still doesn't appear to work on KiCAD 5 stable

The 5 branch is no longer supported. Please upgrade to 5.1.2 which is the latest stable release. I suspect that this may have already been fixed.

[captain_morgan (morganrallen)]

OK, got all my versions straight again (ubuntu distro update disabled PPAs...) and this is still an issue.

The plugin I'm working simply saves current selection using IsSelected and restores it again with SetSelection. Interestingly I've also noticed calling IsSelected visually removes the selection while calling it again still returns True. But if I immediately press m expecting those modules to move, they don't. So some kind of selected limbo state.

The scripts I'm working on can be found here https://gitlab.com/morganrallen/kicad_scripts
