在code examples目录有一个新的目录New DataWindow and UI,里面展示了一些关于DW & UI的新特性,有兴趣的可以看一下: 新的Menu & Toolbar

TreeView DW 
以下是从pdriver.com上收集的: powerbuilder 10.5新功能 从sybase下了个powerbuilder 10.5 beta版,整理了帮助中新功能介绍如下: 1、PB控件 1)增加了MonthCalendar和DatePicker控件 对MonthCalendar控件 a. 如果是EditMask control ,编辑属性时,选择'Maskdatatype'为'datemask!'或'datetimemask!'后,激活'drop-down calendar'选项框,选择打勾,运行程序后可以移动到EditMask control 处直接下拉选择框出现MonthCalendar日历控件 b. 数据窗体日期字段可以设置下拉MonthCalendar 形式的日历,可在constructor等事件中 加入如下语句实现: dw_1.Modify(字段名称+".EditMask.DDCalendar='Yes'") 运行程序后,可以对字段名称直接下拉选择框出现下拉日历控件 2)DatePicker的ValueChanged事件,MonthCalendar的DateSelected 事件 DatePicker的ValueChanged事件 和MonthCalendar的DateSelected事件中可以加入相关代码.比如可以加入如下代码修改single-line edit box文本编辑框的text值: date dt_selected integer li_ret string ls_date li_ret = GetSelectedDate( dt_selected) ls_date = string(dt_selected) sle_2.text = ls_date 3). Animation动画控件 好像只能设置avi后缀名的非压缩或BI_RLE8格式压缩的影像文件.
4)、InkEdit和InkPicture控件 InkEdit:借助Tablet PC(图形输入板)和Tablet PC的书法识别引擎可以转换写入信息为文本; InkPicture: 借助Tablet PC可以把写入信息叠在一张图片上,可以为图片加注释或直接用来签名. 2、新增调用扩展和decimal数值类型支持 1)可以直接在System Tree通过右键弹出式菜单' imported PB extension '导入 主程序搜索目录下的.pbx or .dll 后缀名文件到库中,省去以前版本 要同时拷贝 PBX or DLL 文件并设置运行时的主程序搜索目录; 2)decimal数值类型由支持以前版本的18 digits 到32digits.datawindow中的表达式也对此提供相关支持.
