Bug-fixes

• Scroll region under non-Microsoft-Windows® systems.

  An <Configure> event may appear before the window is mapped on screen. It thus can happen, that the container frame is smaller than the canvas window; leading to a perpetual wrong scroll region.

• Resize window and precreated rows.

  Rows are never deleted! This is highly problematic when the window gets resized (smaller), where row-artifacts will remain. In normal circumstances this artifacts are covered by the newly rendered items...

New Features

• Option Database Usage.

  Option Database usage is activated. Only lowercase are allowed (e.g. alternatecolor instead of alternateColor). The new window class is: »Hugelist«.

• »radius«, Option Database entry only active with tkpathHugelist, creates rounded etiquettes for unselected entries.

• »justifyRadius«, Option Database entry only active with tkpathHugelist, creates »left«, »right« or »middle« (both sided) rounded etiquettes for unselected entries.

• Performance Improvements.

  Some performance improvements during window creation –related to the option database. Two successive configuration sets are applied whenever a window is instantiated. The instance set is used to remove duplicated entries from the default set.

• »-vector«, . The »-vector« property allows the definition of a canvas graphics, following the Goolbar vector specification.

Visual Appearance

• Related to Aqua OSX®.

  Items and multi-selection are separated by a single pixel-width line.

• Alternate color combined with item background color.

  See option database entries: colorOpacity , alternateOpacity , disabledColorOpacity and disabledAlternateOpacity control the color mixing. There are no command line arguments for these Option Database entries.

• The alternate color fades into the background, when the window is disabled.

Technical Changes

• width is derived from the window itself.

• opget from the Runtime Library 3.0 is being used.

  opget is necessary for accessing the Option Database –option get is caught by the hugelist's internal alias option:get.

  I would have preferred to use "option get" instead of opget! opget introduces a Runtime Library 3.0 dependency, which I intended to avoid.

  hugelist version 1.5 contains a local copy of opget , to make it again independent from the Runtime Library 3.0.

• Version 1.5 contains a new window property -ondemandcommand. This property accepts a Tcl-procedure or an empty string as its value. The empty string disables on-demand data gathering.

  The registered on-demand command is queried every time an item is displayed inside the of a hugelist. The on-demand command gets queried three times for each item, to retrieve the actual text, image and a vector. Default values for text, image and vector are part of the query.

  The signature for ondemandcommand is as following:

  proc ondemand {type hugelist ID listindex defaultvalue } {
     ...
     # value gets displayed:
     return $value
  }
