我正在申请取代两种非常相似的口语的不同词语。按时间划分的单词数量可能至少达到10.000+。单词没有很大的差异,它几乎是相同的语言,但是存在差异。
所以,我设法用足够快的速度替换Memo中的单词,但我不知道如何在Memo中选择所有替换的单词,以便可以看到哪些单词被替换。这可能吗?
这就是替换单词的方式:
procedure TForm1.TranslateExecute(Sender: TObject);
var i: integer;
S, OldPattern, NewPattern: string;
begin
S:= Memo1.Lines.Text;
for i := 0 to (StrListV.Count - 1) do {StrListV is created earlier, contains words that should be replaced}
begin
OldPattern:= StrListV.Strings[i];
NewPattern:= StrListV1.Strings[i]; {StrListV1 contains new words}
S:= FastStringReplace(S, OldPattern, NewPattern,[rfReplaceAll]);
end;
Memo1.BeginUpdate;
Memo1.Clear;
Memo1.Lines.Text:= S;
Memo1.EndUpdate;
end;
答案 0 :(得分:3)
TMemo
或TRichEdit
都不支持多项选择,因此您无法突出显示已替换的字词。但是使用TRichEdit
,您可以做的是更改您替换的单词的前景/背景颜色。
TRichEdit
有一个FindText()
方法(包装EM_FINDTEXT
消息),返回搜索字符串的索引。在循环中调用它,或者每个找到的单词都可以选择它,设置颜色,并用新文本替换它。重复直到FindText()
找不到更多匹配项。
尝试这样的事情:
uses
RichEdit, CommDlg;
procedure TForm1.TranslateExecute(Sender: TObject);
var
I, Pos: Integer;
EventMask: LRESULT;
OldPattern, NewPattern: string;
Find: RichEdit.FINDTEXT;
Rng: RichEdit.CHARRANGE;
Fmt: RichEdit.CHARFORMAT2;
begin
EventMask := SendMessage(RichEdit1.Handle, EM_SETEVENTMASK, 0, 0);
RichEdit1.Lines.BeginUpdate;
try
for I := 0 to StrListV.Count - 1 do
begin
OldPattern := StrListV.Strings[I];
NewPattern := StrListV1.Strings[I];
Pos := 0;
repeat
Find.chrg.cpMin := Pos;
Find.chrg.cpMax := -1;
Find.lpstrText := PChar(OldPattern);
Pos := SendMessage(RichEdit1.Handle, EM_FINDTEXT, FR_DOWN or FR_WHOLEWORD, LPARAM(@Find));
if Pos = -1 then Break;
Rng.cpMin := Pos;
Rng.cpMax := Pos + Length(OldPattern);
ZeroMemory(@Fmt, SizeOf(Fmt));
Fmt.cbSize := SizeOf(Fmt);
Fmt.dwMask := CFM_COLOR or CFM_BACKCOLOR;
Fmt.crTextColor := ColorToRGB(clHighlightText);
Fmt.crBackColor := ColorToRGB(clHighlight);
SendMessage(RichEdit1.Handle, EM_EXSETSEL, 0, LPARAM(@Rng));
SendMessage(RichEdit1.Handle, EM_SETCHARFORMAT, SCF_SELECTION, LPARAM(@Fmt));
SendMessage(RichEdit1.Handle, EM_REPLACESEL, 0, LPARAM(PChar(NewPattern)));
Inc(Pos, Length(NewPattern));
until False;
end;
finally
RichEdit1.Lines.EndUpdate;
SendMessage(RichEdit1.Handle, EM_SETEVENTMASK, 0, EventMask);
end;
end;
