delphi 7怎样设置代码编辑窗口关键字高亮显示

delphi 7怎样设置代码编辑窗口关键字高亮显示

如果是d7，那么就用cnpark的高亮设置那里修改。
如果是d7以上版本，就把option-editor option-color -element 里把 line highlight 改回原来或者你想要的颜色。
或者
自定义模式下把所有element属性的background color 的default默认都改成想要的颜色.

肯定不能在delphi中设置，下面是我在网上找到的代码，你可以试试：

在 RichEdit 中实现代码着色

下面的代码将以指定颜色对一些指定单词着色，就象delphi中的代码编辑器那样。

procedure CodeColors(Form : TForm;Style : String; RichE : TRichedit;
InVisible : Boolean);
const
// 符号...
CodeC1: array[0..20] of String = ( '# ', '$ ', '( ', ') ', '* ', ', ',
'. ', '/ ', ': ', '; ', '[ ', '] ', '{ ', '} ', ' < ', '> ',
'- ', '= ', '+ ', ' ' ' ', '@ ');
// 保留字...
CodeC2: array[0..44] of String = ( 'and ', 'as ', 'begin ',
'case ', 'char ', 'class ', 'const ', 'downto ',
'else ', 'end ', 'except ', 'finally ', 'for ',
'forward ', 'function ', 'if ', 'implementation ', 'interface ',
'is ', 'nil ', 'or ', 'private ', 'procedure ', 'public ', 'raise ',
'repeat ', 'string ', 'to ', 'try ', 'type ', 'unit ', 'uses ', 'var ',
'while ', 'external ', 'stdcall ', 'do ', 'until ', 'array ', 'of ',
'in ', 'shr ', 'shl ', 'cos ', 'div ');

在代码编辑窗口，点击右键选择Properties，然后在Color选项卡里面改
