I am working on implementing spellchecker in an MFC application. What I want to do is display red lines under incorrectly spelled words.
I found one example where it is done but it works only for a simple edit box because it can simply use the edit controls default font for doing calculations to draw the squiggly lines. But it does not work for a rich edit control as in rich edit control it is possible that different words can have different fonts. In this case the example I found draws lines at incorrect places.
Please let me know if someone has already done this for CRichEditCtrl? (it must handle text of any font/size that is present in the rich edit control.)
Thanks,
Sachin
CHARFORMAT2 format;
SecureZeroMemory(&format, sizeof(CHARFORMAT2));
format.cbSize = sizeof(CHARFORMAT2);
format.dwMask = CFM_UNDERLINE|CFM_UNDERLINETYPE;
format.dwEffects = CFE_UNDERLINE;
format.bUnderlineType = CFU_UNDERLINEWAVE | 0x50;
SendMessage(EM_SETCHARFORMAT, SCF_ALL, (LPARAM)&format);
I hope this will get the underline in your text
Use the EM_SETCHARFORMAT message:
CHARFORMAT2 format;
SecureZeroMemory(&format, sizeof(CHARFORMAT2));
format.cbSize = sizeof(CHARFORMAT2);
format.dwMask = CFM_UNDERLINE|CFM_UNDERLINETYPE;
format.dwEffects = CFE_UNDERLINE;
format.bUnderlineType = CFU_UNDERLINE
window->SendMessage(EM_EXSETSEL, NULL, (LPARAM)&range);
window->SendMessage(EM_SETCHARFORMAT, SCF_SELECTION, (LPARAM)&format);
