TMemo的Delphi属性行中的最大字符串长度 [英] Maximum Length of String in Delphi property Lines of TMemo
问题描述
我一直在寻找TMemo.Lines中String的最大长度为1024的原因，但尚未找到.
I've been searching the reason why the maximum length of String in a TMemo.Lines is 1024, but not found yet.
我有一个文本文件，其中包含定界的/csv数据，长度约为2000个字符. 在处理文件之前，我会使用备忘录对其进行预览.
I have a text file which contains delimited / csv data which length is around 2000 characters. I use a memo to preview it before I process the file.
memo.Lines.LoadFromFile(textFile);
memo.Lines.LoadFromFile(textFile);
我已将WordWrap设置为FALSE，并将scrollBar设置为ssHorizontal.因此，任何记录都不会被包装到下一行.
I have set the WordWrap to FALSE, and scrollBar to ssHorizontal. So any record will not be wrapped to the next line.
但是当我对备忘录行进行迭代时，我发现每个索引中的最大String保留为1KB或1024个字符.其余的将被截断到下一行.
But when I iterate the memo.Lines, I found that the maximum String hold in each index is 1KB or 1024 characters. The rest is truncated to the next line.
但是，如果我使用TStringList加载文件，则当该行超过1024个字符时，该行不会被截断到下一个索引.当我使用TRichEdit时不会发生这种情况.
But if I use TStringList to load the file, the row is not truncated to the next index when it reaches more than 1024 characters. This is not happen when I use TRichEdit.
- 任何人都可以解释这种现象吗?
- 这是TMemo的默认行为吗?
我用D2006尝试这个.
I use D2006 to try this.

正如伟大的彼得·贝特(Peter Under)所说:
As the great Peter Below says :
...这与 出现行长度限制.这 极限实际上只是视觉上的，是由 控件呈现文本的方式.
...This has nothing to do with the appearend line length limit. This limit is really just visual, caused by the way the control renders its text.
再见.
