"""
Dialogs that query users and verify the answer before accepting.
Use ttk widgets, limiting use to tcl/tk 8.5+, as in IDLE 3.6+.

Query is the generic base class for a popup dialog.
The user must either enter a valid answer or close the dialog.
Entries are validated when <Return> is entered or [Ok] is clicked.
Entries are ignored when [Cancel] or [X] are clicked.
The 'return value' is .result set to either a valid answer or None.

Subclass SectionName gets a name for a new config file section.
Configdialog uses it for new highlight theme and keybinding set names.
Subclass ModuleName gets a name for File => Open Module.
Subclass HelpSource gets menu item and path for additions to Help menu.
"""
# Query and Section name result from splitting GetCfgSectionNameDialog
# of configSectionNameDialog.py (temporarily config_sec.py) into
# generic and specific parts.  3.6 only, July 2016.
# ModuleName.entry_ok came from editor.EditorWindow.load_module.
# HelpSource was extracted from configHelpSourceEdit.py (temporarily
# config_help.py), with darwin code moved from ok to path_ok.
