Here's the picture: when an application calls TextOut() for printing text, the usual (at least in my case) call sequence in Wine is TextOut() TextOutA() ExtTextOutA() ExtTextOutW() (the one I patched) GetTextExtentPointW() GetTextExtentPoint32W() (the wide-char version of the one you mentioned) GetTextExtentExPointW() WineEngGetTextExtentExPoint() (the one that actually gets the individual character widths) That is, at some point, TextOut() indirectly uses GetTextExtentPoint32() to get the dimensions, okay. But what I need is to check the text width *after* it was output by TextOut() -- in other words, after the function has returned, to see if it output the text properly. In Wine, I tried the trick of making ExtTextOutW() return the said value, and the tests passed without a hitch, which means the text is being properly justified. The problem is that such is not an acceptable way of doing things, and, to use Dan Kegel's words, that is not going to fly on Windows. To be a bit clearer, in my tests I do call GetTextExtent32() in order to compute the remaining white space for the justification part, and what I want to check is whether TextOut() understood it right or not. - Pedro.
