--- Requests treeview contents from browser that matches pm_entry's text.
--- This function is called internally and shouldn't be called by a script.
--- @param full_path A numerically indexed table of treeview item parents. The
---   first index contains the text of pm_entry. Subsequent indexes contain the
---   ID's of parents of the child requested for expanding (if any).
--- @param expanding Optional flag indicating if the contents of a parent are
---   being requested. Defaults to false.
--- @return table of tables to for display in the treeview (single level).
---   Each key in the return table is the treeview item's ID. The table value
---   has the following recognized fields:
---     parent - boolean value indicating if this entry can contain children. If
---       true, an expanding arrow is displayed next to the entry.
---     pixbuf - a string representing a GTK stock-id whose icon is displayed

--- Markdown:
--- ## Fields
---
--- * `entry_text`: The text in the entry.
--- * `width`: The width of the project manager.
--- * `cursor`: The cursor in the project manager (string representation of
---   current `GtkTreePath`).
---
--- ## Overview
---
--- The PM uses different [browsers][browsers] to display heirarchical data.
---
--- [browsers]: ../modules/textadept.pm.browser.html
---
--- ## Interactive Search
---
--- Typing text into the project manager view begins the interactive search.
--- If the text matches ANY part of an item in the view (case sensitively), the
--- item is highlighted and subsequent matches can be navigated to using the
--- up/down arrow keys.
---
--- ## Customizing Look and Feel
---
--- There is no way to theme the dialog from within Textadept. Instead you can
--- use [GTK Resource files][gtkrc]. The pm entry and view have widget names of
--- `textadept-pm-entry` and `textadept-pm-view` respectively.
---
--- [gtkrc]: http://library.gnome.org/devel/gtk/unstable/gtk-Resource-Files.html.
---
--- My RC file looks something like this:
---
---     pixmap_path "/usr/share/icons/Tango/:/home/mitchell/.icons/prog/"
