篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了(原创)两种自定义texteditor的方式相关的知识,希望对你有一定的参考价值。
在平常的需求中,可能会遇到需储存一些自定义的长文本的情况,这种时候,就需要用到textedictor,也就是文本编辑器,创建texteditor需要用到容器类(例如cl_gui_custom_container)和texteditor控制器类(cl_gui_textedit)。
本文所说的两种自定义texteditor方式,一种方式是直接使用这两种类,一种方式是使用SAP提供的封装好的函数,但是本质上这两种方式都是使用容器类和texteditor控制器类,只不过第二种方式SAP已经将其封装成一个函数供给我们直接使用而已。
下面给出用两种方式自定义texteditor的DEMO。
第一种:直接使用容器类和texteditor控制器类。
输出目标:点保存时,输出文本框中文本。

屏幕100与第一种方式相同,这里就不贴图了。

WHEN OTHERS. ENDCASE. ENDMODULE.
当然,在实际运用中,我们通常会去SE75自定义一个文本对象,然后通过SAVE_TEXT或CREATE_TEXT方式将texteditor中读取到的数据存入到底表中。
