jopen 9年前

Calligra是一个轻量级的办公组件，旨在为所有平台提供一个基于开放标准的优秀办公软件。除了标准的办公软件外，该版本新增加了示意图和流程 图编辑器Flow，以及笔记工具Braindump。Calligra兼容MS Office 2007 文件，改进了启动速度、性能、文本布局，为平板和智能手机提供Calligra Activ和 Calligra Mobile两种用户界面。

开源轻量级办公组件，Calligra 2.9.8 发布

Calligra 2.9.8 发布，此版本改进了应用和底层开发框架，主要是重要的 bug 修复：

General

  • Make the maximum default toolbox button size 22px (bug 352110)

  • Fix display of toolbox icons on CentOS

  • Fix crash when typing a bogus color-set name in the color set dialog

Kexi

  • General:

    • Avoid repeated opening of the same object, possible for large data

  • Tables:

    • Table view’s combo box list: ensure that highlighted row is visible

    • Table view: update the highlighted row while scrolling the viewport

  • Queries:

    • With minor exceptions these functions now work with SQLite, MySQL, PostgreSQL

    • This make Kexi unique environment supporting unified SQL

    • In many cases substitute functions are used to make the result work in a portable way

    • No extra i18n added; will be added in a KDb port

    • Implementation of the function parser supports:

    • checking number of arguments

    • checking types of arguments, sometimes “any number” or “any text or BLOB”

    • checking compatibility of arguments in function

    • checking relation of value of arguments in function, e.g. value of the first argument smaller than second’s

    • checking NULL arguments in function; then most often the result is NULL

    • argument overloading or optional arguments, e.g. round(X) and round(X,Y)

    • displaying of human-readable error messages when the above constraints are not met, for example “Three arguments required” or “Function does not accept any arguments”

    • easy extensibility using just a few lines of code.

    • New feature: Add support for 22 typical scalar SQL functions (wish 352631):
      abs(X), ceiling(X), char(X1,X2,…,XN), coalesce(X,Y,…), floor(X), greatest(X,Y,…) and its alias max(X,Y,…), hex(X), ifnull(X,Y), instr(X,Y), least(X,Y,…) and its alias min(X,Y,…), length(X), lower(X), ltrim(X), ltrim(X,Y), nullif(X,Y), random(), random(X,Y), replace(X,Y,Z), round(X), round(X,Y), rtrim(X), rtrim(X,Y), soundex(X), trim(X), trim(X,Y), unicode(X), upper(X).

    • New feature: Add support for hex literals, useful for opearting on BLOBs in queries: X’ABCD’ (SQL) and 0xABCD (ODBC) formats

    • Optimize evaluating type of expressions (also for database migration)

    • Fix broken floating-point constants in Kexi SQL queries, e.g. “1.002” was interpreted as “1.2” (bug 352363)

    • After parsing numbers are now kept losslessly as byte arrays, what enables unlimited precision

    • Improve parsing/sending BLOB literals

    • Improve performance of the SQL scanner

    • Make parsing of argument lists in scalar SQL functions more efficient by reversing direction

  • MySQL databases:

    • Set client_library_version property for newer versions of MySQL

  • PostgreSQL databases:

    • Return NULL value for columns of NULL type

    • Switch to “BYTEA HEX” escaping while generating native statements

    </ul>

    Calligra Flow

    • Fix lack of update of Flow’s canvas and page count when deleting the current page

    Calligra Stage

    • Let Ctrl+Home/Ctrl+End go to top/bottom of text shape in stage. Much more expected than exiting edit-mode and going to the first or last page.

    • Fix crash when loading a presentation created with LO Impress

    • Don’t leave temporary files around
