list - 在 WRITE 语句中使用颜色变量

Question

如何使用颜色值变量？例如，这对我有用：

write:/10  'test' COLOR COL_HEADING.

我认为颜色是整数，所以我尝试了：

data:
gv_mycolor type I.
gv_mycolor = 5.
write:/10  'test' COLOR gv_mycolor.

第二个代码给了我一个错误：“颜色 gv_mycolor 不是预期的；只允许 1 到 7 或相关的颜色 ID。声明

FORMAT COLOR = gv_mycolor.

对我有用，我只是写语句有问题。

有人可以帮忙吗？

Answer 1

DATA colour TYPE i VALUE 2.

WRITE:/10  'test' COLOR = colour .

你必须使用等号，这就是它的全部内容...... ABAP，这是有趣的陈述：P

Short answer to your question: The syntax does not allow you to do this as per the compiler message. The best you can do is to combine the FORMAT and WRITE statements in a macro, but this is very old-school, and will probably not teach you too much that is relevant.

Have a look at package SLIS where there are many examples (BCALV_GRID*) of how to implement ALV lists and grids. These are used much more frequently, even in Web Dynpro. The CL_SALV* classes also provides a nice simplified (and supported) interface to implement ALV grids. (See this answer for a full example).
