# Each megawidget gets a namespace of the same name inside the Widget namespace
|
|
# Each of these has an array opt, which contains information about the
|
|
# megawidget options. It maps megawidget options to a list with this format:
|
|
# {optionType defaultValue isReadonly {additionalOptionalInfo}}
|
|
# Option types and their additional optional info are:
|
|
# TkResource {genericTkWidget genericTkWidgetOptionName}
|
|
# BwResource {nothing}
|
|
# Enum {list of enumeration values}
|
|
# Int {Boundary information}
|
|
# Boolean {nothing}
|
|
# String {nothing}
|
|
# Flag {string of valid flag characters}
|
|
# Synonym {nothing}
|
|
# Color {nothing}
|
|
#
|
|
# Next, each namespace has an array map, which maps class options to their
|
|
# component widget options:
|
|
# map(-foreground) => {.e -foreground .f -foreground}
|
|
#
|
|
# Each has an array ${path}:opt, which contains the value of each megawidget
|
|
# option for a particular instance $path of the megawidget, and an array
|
|
# ${path}:mod, which stores the "changed" status of configuration options.
|
|
|
|
# Steps for creating a bwidget megawidget:
|
|
# 1. parse args to extract subwidget spec
|
|
# 2. Create frame with appropriate class and command line options
|
|
# 3. Get initialization options from optionDB, using frame
|
|
# 4. create subwidgets
|
|
|
|
# Uses newer string operations

# copyinit performs basically the same job as init, but it uses a
|
|
# existing template to initialize its values. So, first a perferct copy
|
|
# from the template is made just to be altered by any existing options
|
|
# afterwards.
|
|
# But this still saves time as the first initialization parsing block is
|
|
# skipped.
|
|
# As additional bonus, items that differ in just a few options can be
|
|
# initialized faster by leaving out the options that are equal.
|
|
|

# This function is currently used only by ListBox::multipleinsert, but other
