Qt，是用来开发 KDE 应用程序 GUI 界面的工具包，最初并不是以完全自由许可证发行的，因为奇趣科技公司（TrollTech）也有商业化的部分。奇趣公司是 Qt 的创造者，为 KDE 开发的专用程序必须获得奇趣公司的许可授权，而且 Qt 的任何升级都必须经过奇趣公司。但是 KDE 软件是一个开源项目，使用 Qt 做开发的做法曾一度在开源界激进者中引起强烈争议。现在 Qt 又在 GPL 许可下重新授权，那么这些争论也就不复存在了。当然，这是 KDE 发展历程中非常重要的一环。

为什么 KDE 开发人员要选 Qt？

  • Qt 是在 UNIX 平台下最好的图形界面（GUI）开发包。一个桌面环境的成功极度依赖其应用软件。使用 Qt 将会极大地促进应用软件的开发，从而促进 KDE 的发展。
  • Qt 对所有人都是免费的，包括它的代码，为自由软件的开发和发行提供基础。
  • 我们积极地鼓励商业软件公司为 KDE 提供应用软件。这些公司需要成熟、高质量的工具包和技术支持，而在 GPL 下发行的工具包都不具备这些条件。
  • 重新开发一套在 LGPL 下发行的，与奇趣公司发行质量相当的 Qt 工具包会耗费时间，并且也不会比先开发一个易用、自由的开放性桌面更加重要。

KDE 自由 Qt 基金会

为了解决这个问题，KDE 项目小组和奇趣科技公司共同创立了KDE 自由 Qt 基金会。该基金会保证了 Qt 作为自由开发框架的运作。也就是说，如果奇趣科技公司不再将 Qt 作为自由软件发布，现有的版本会将以 BSD 式的许可证发布 —— 一个与 GPL 或 LGPL 本质上相似但更为宽松的许可证。

这个重发布的决定将由投票决定，两位代表将来自 KDE 基金会（非属奇趣公司），两位来自奇趣公司。若票数相同，KDE 的投票会占有更高的权重。

Harmony 项目

那些更加看重 GPL 版权的人们启动了“和谐项目”（Harmony Project）——旨在克隆一份 GPL 许可下的 Qt 版本。这个项目当时发展迅猛，也就没有给开源界激进者们留下任何理由挑刺 KDE 顺从而可敬的名声。当然随着奇趣公司以 GPL 许可证开源 Qt 的决定，这个项目也就不复存在了。
