I have a CRichEditCtrl (actually I have a class that is a subclass of a CRichEditCtrl, a class that I defined) that is populated by many lines of text with both horizontal and vertical scroll bars. The purpose of this control is to display a string that is searched for in a larger text along with n characters to the right and left (e.g. if the user searches for "the" then they would get a list of all the instances of "the" in the text with (if n = 100) 100 characters to the left and right of each found instance to provide context).
The query string needs to be lined up between each row. Before this program had Unicode support, just setting the font to Courier did the trick, but now that I've enabled Unicode support, this no longer works.
I've tried using monospaced fonts, but as far as I can tell, there aren't any that are for all characters. It seems to me that the latin characters all have one size, and the Chinese characters have another (I've noticed lines of text with all latin characters line up and ones with all Chinese characters line up, but ones with both do not line up).
I've also tried center aligning the text. Since the query string in each line is in the exact center, they should all line up, but I cannot seem to get this to work, the SetParaFormat call seems to just get ignored. Here's the code I used for that:
long spos, epos;
GetSel(spos, epos);
PARAFORMAT Pfm;
GetParaFormat(Pfm);
Pfm.dwMask = (Pfm.dwMask | PFM_ALIGNMENT);
Pfm.wAlignment = PFA_CENTER;
SetSel(0, -1);
SetParaFormat(Pfm);
SetSel(spos, epos);
I do this everytime text is inserted in the ctrl, but it has no affect on the program.
Is there anyway to get the query word in each line of text to line up even when there are interspersed Chinese and latin characters? (and possibly any other character set)
See http://msdn.microsoft.com/en-us/library/bb787940(v=vs.85).aspx, in particular the cTabCount and rgxTabs members of the PARAFORMAT (or PARAFORMAT2) structure, which allow you to set tabstops.
