Reference
TRichMemo methods
SetTextAttributes
procedure SetTextAttributes(TextStart, TextLen: Integer; AFont: TFont);
- TextStart : Integer - the first character to be modified
- TextLen : Integer - number of characters to be modified
- AFont : TFont - a font that should be applied to the part of the text
procedure SetTextAttributes(TextStart, TextLen: Integer; const TextParams: TFontParams);
- TextStart : Integer - the first character to be modified
- TextLen : Integer - number of characters to be modified
- TextParams : TFontParams - font parameters to be set
SetTextureAttributes methods are changing specified text range style. Font parameters is passed in both methods, by AFont parameter (LCL TFont object) or by TFontParams (declared at RichMemo).
Setting text attributes does not change current selection. If it's necessary to modify the style of currently selected text, you should SelStart and SelLength as a text range values:
RichMemo1.SetTextAttributes(RichMemo1.SelStart, RichMemo1.SelLength, FontDialog1.Font);
GetTextAttributes
function GetTextAttributes(TextStart: Integer; var TextParams: TFontParams): Boolean; virtual;
- TextStart : Integer - the character position to be queried for font parameters
- var TextParams : TFontParams - output value, filled with charachter's font attributes. If the method fails and returns false, record's field values is undefined.
Fill font params of the character, at TextStart position. Method returns True if textstart is valid character position, and False overwise.
