Overview

This class is a dialog where the user can choose a file to open among the files of the project.

The dialog is made by two widgets: a KDE::LineEdit, where the user can enter a file pattern, and a Qt::ListView, where all files in the project matching the given regexp are shown. The user can choose the file either by pressing the Return key or by activating an item in the list.

The pattern is interpreted as a regexp and is checked against the whole path of the file if it contains a pattern separator character (the '/' character on UNIX) and only against the name of the file otherwise. When the user changes the pattern, the file list is changed accordingly. This is achieved using a filter model derived from Qt::SortFilterProxyModel.

def chosen_file

  idx = selection.first
  File.join(@base_dir, idx.data.to_string.gsub(/\A\./,''))
end

#eventFilter(obj, e) ⇒ Object

Reimplements Qt::Object.eventFilter. It blocks the KeyPress events for the up and down keys (but only if there's no modifier) and redirects them to the file list widget. All other events are allowed to pass. This allows to scroll the list without taking the focus from the pattern widget. =====Arguments

obj

the object whose events should be filtered

e

the event
