QtitanDataGrid 是一个用于 Qt 的商业 DataGrid 组件,它为向最终用户呈现表格数据提供了真正非凡的可能性。组件吸收了用于显示表格的用户界面构造领域的所有现代成就。目前,是 Qt 市场上唯一具有如此令人印象深刻的高级功能和出色性能的网格组件。(查看详情)

QtitanDataGrid使你能够从不同的来源加载各种类型的数据到一个快速、灵活和功能性的可编辑网格中,支持排序、分组、报告、创建带状列、按钮的拖放和大量其他方便的功能。这个数据网格帮助具有Delphi和C++背景的新手和经验丰富的Qt开发者使用同样全面的高级可编辑网格功能,他们已经习惯了在相应的IDE中使用这些功能,而这些功能并不是标准Qt库的一部分。
