Method: MetaRuby::GUI::ModelSelector#map_index_from_source

Defined in:
lib/metaruby/gui/model_selector.rb

#map_index_from_source(source_index, reset_filter: true) ⇒ Qt::ModelIndex

Maps a model index from the source index to the filtered index, e.g. to select something in the view.

In addition to the normal map_from_source call, it allows to control whether the filter should be reset if the index given as parameter is currently filtered out

Parameters:

  • source_index (Qt::ModelIndex) —

    an index valid in #browser_model

  • reset_filter (Boolean) (defaults to: true) —

    if true, the filter is reset if the requested index is currently filtered out

Returns:
