I found this code over the net. This puts background color to the selected texts on Trichedit:
uses
RichEdit;
procedure RE_SetSelBgColor(RichEdit: TRichEdit; AColor: TColor);
var
Format: CHARFORMAT2;
begin
FillChar(Format, SizeOf(Format), 0);
with Format do
begin
cbSize := SizeOf(Format);
dwMask := CFM_BACKCOLOR;
crBackColor := AColor;
Richedit.Perform(EM_SETCHARFORMAT, SCF_SELECTION, Longint(@Format));
end;
end;
// Example: Set clYellow background color for the selected text.
procedure TForm1.Button1Click(Sender: TObject);
begin
RE_SetSelBgColor(RichEdit1, clYellow);
end;
However, what I need is to exclude space characters. Can someone help me? Any idea would be helpful? My idea would be to select all space characters and then format it but then I don't know how to select them. By the way, I am using delph开发者_如何学JAVAi 2009.
@junmats, with this code you can select any word in a richedit control.
tested in Delphi 2010 and windows 7
uses
RichEdit;
procedure SetWordBackGroundColor(RichEdit : TRichEdit; aWord : String;AColor: TColor);
var
Format: CHARFORMAT2;
Index : Integer;
Len : Integer;
begin
FillChar(Format, SizeOf(Format), 0);
Format.cbSize := SizeOf(Format);
Format.dwMask := CFM_BACKCOLOR;
Format.crBackColor := AColor;
Index := 0;
Len := Length(RichEdit.Lines.Text) ;
Index := RichEdit.FindText(aWord, Index, Len, []);
while Index <> -1 do
begin
RichEdit.SelStart := Index;
RichEdit.SelLength := Length(aWord) ;
RichEdit.Perform(EM_SETCHARFORMAT, SCF_SELECTION, Longint(@Format));
Index := RichEdit.FindText(aWord,Index + Length(aWord),Len, []) ;
end;
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
SetWordBackGroundColor(RichEdit1,' ',clYellow);// will mark all spaces
end;
if you wanna select all words except the spaces, you can do something like this
Procedure GetListofWords(Text : String; var ListofWords : TStringList);
var
DummyStr : String;
FoundWord : String;
begin
DummyStr := Text;
FoundWord := '';
if (Length(Text) = 0) then exit;
while (Pos(' ', DummyStr) > 0) do
begin
FoundWord := Copy(DummyStr, 1, Pos(' ', DummyStr) - 1);
ListofWords.Add(FoundWord);
DummyStr := Copy(DummyStr, Pos(' ', DummyStr) + 1, Length(DummyStr) - Length(FoundWord) + 1);
end;
if (Length(DummyStr) > 0) then
ListofWords.Add(DummyStr);
end;
procedure TForm1.Button1Click(Sender: TObject);
var
ListofWords : TStringList;
i : integer;
begin
ListofWords:=TStringList.Create;
try
GetListofWords(RichEdit1.Lines.Text,ListofWords);
if ListofWords.Count>0 then
for i:=0 to ListofWords.Count - 1 do
SetWordBackGroundColor(RichEdit1,ListofWords[i],clYellow);
finally
ListofWords.Clear;
ListofWords.Free;
end;
end;
