v0.3.4

Significant changes

Extensions

• The ColumnResizer extension now emits a dgrid-columnresize event when a resize
  occurs; if initiated by the user, the event will include a parentType property
  indicating the type of event that triggered it. If this event is canceled,
  the column will not be resized. (#320)
• The ColumnResizer extension now honors a width property included on column
  definition objects for the purpose of initializing the width of a column; this
  can be useful if it is desired to persist and restore custom column widths
  from a cookie or other local storage. (#321)
• The ColumnResizer extension now honors a resizable property included on
  column definition objects for the purpose of disallowing resize of specific
  columns. (#325)

Other changes and fixes

General/Core

• Resolved an issue in List relating to scrolling and preload nodes. (#318, #323)

Mixins

• The ColumnSet mixin now supports horizontal mousewheel events. (#239)

Column Plugins

• The column plugins (editor, selector, and tree) can now be invoked without
  a column definition object at all, if no properties need to be set. This
  is mostly useful for selector. (#324)
• Fixed an issue with the selector plugin when a column definition lacks a
  label property. (#324)
• Always-on editor columns now honor the canEdit function on column definitions
  at the time each cell is rendered.
• Always-on editor columns now properly revert values if the dgrid-datachange
  event is canceled. (#252)

Extensions

• The ColumnResizer extension's resize indicator now follows the cursor
  even when dragging beyond the grid's boundaries, and reacts if the mouse
  button is released even outside the boundaries of the browser window. (#310)
