Since the addition of all nets to the net navigator, performance on very
complex designs is unacceptable. Not updating the net navigator is a
cheap and dirty short term fix. Users with complex designs will not be
able to use the net navigator. A better fix to resolve the performance
issues needs to be implemented.
Ignore bus member connection subgraphs. They do not have a valid net
name nor do they contain schematic items. This prevents empty nodes
from being added to the tree. They can be reintroduced in the future
if someone wants to pursue it.
Freeze the wxTreeCtrl while populating it and thaw when done to prevent
any unnecessary repainting.
Add profiling to test how long it takes to rebuild the net navigator.
The recently added populate the navigator with all nets when no net
is highlighted has exposed some potential performances issues with some
versions of wxWidgets on certain platforms. Namely wxWidgets 3.2.4 on
Linux GTK.
Fix an issue where a sheet name change would not update the highlighted
net navigator resulting in a stale human readable sheet path.
Prevent the highlighted net navigator from being rebuilt twice when
loading a schematic. SCH_EDIT_FRAME::RefreshNetNavigator() was being
called from both SCH_EDIT_FRAME::UpdateHierarchyNavigator() and
SCH_EDIT_FRAME::RecalculateConnectivity().
Add a new trace helper "KICAD_UI_PROFILE" to show trace output when
profiling user interface performance. It's used in the net navigator
profiling mentioned above.
Reuse PROF_TIMER::Show() to generate string for PROF_TIMER::to_string().
Removes old defines and work arounds for earlier wx versions and adds a
CMake requirement to use at least 3.2 (or the minimum matching wxPython
version)
The TOOL_ACTION_ARGS construction method is supposed to be fairly light
weight, so instead of creating/destroying strings all the time, pass
string_views to the actual string data instead.
wx doesn't currently support string_view -> wxString implicitly
currently, so we have to do the conversion ourself.
This library is meant to move non-EDA items (language extensions,
library extensions, etc.) into the lowest-level of our dependency chain.
This library should never depend on anyother non-thirdparty code in the
kicad codebase.
