To fix this problem i found a solution but it not very good but it work in version >2
IN
I ADD Declaration
| Code: | const
EM_SETTYPOGRAPHYOPTIONS = WM_USER + 202;
TO_ADVANCEDTYPOGRAPHY = 1; |
AND
| Code: | | SendMessage(RichEdit.Handle, EM_SETTYPOGRAPHYOPTIONS, TO_ADVANCEDTYPOGRAPHY, TO_ADVANCEDTYPOGRAPHY); |
BEFORE
| Code: | | Range.chrg.cpMin := SendMessage(RichEdit.Handle, EM_FORMATRANGE, 1, integer(@Range)); |
---
You can Change BY With this change you can use JvRichEdit and LMDRichEdit
Sory for my bad ENGLISH |

Thanks Sebastian for the fix.
At least on Windows XP there's no problem with rendering justified rich text with the TPrintPreview component. The component doen't render the text itself, and it's the Windows's task to do it. Maybe there's a bug on some versions of common controls, however I don't know about it and it's not my fault, please don't blame me.
In addition, I won't change the parameter's type from TCustomRichEdit to TCustomMemo. A memo control doesn't support EM_FORMATRANGE message. If a rich edit control wrongly drived from a TCustomEdit instead of a TCustomRichEdit, I might not do the same mistake, shall I? If you are sure that the control is a rich edit, type cast it as what it should be, and pass it to the method. |
