Any use for glyph bounding boxes in printer driver?
by Ian Pilcher 27 Jul '01

27 Jul '01

Currently, the Wine PostScript driver stores the bounding box (xMin, yMin, xMax, yMax) for every glyph in every font. This information is not currently used, and I'd like to get rid of it. (Note: this is distinct from the advance width of each glyph, which is certainly required.) >From what I can tell, there is no API that a Win32 application or the Windows GDI can use to get this information from a printer driver. Since I'm not that familiar with either, however, I figure I should try to confirm that this is indeed the case. So, does anyone know of any API that an application or the GDI can use to get the dimensions of an individual glyph from a "real" Windows printer driver? (I have verified that calling the GetTextExtentPoint functions with a one-character string returns the height of the font, not the height of the glyph. For example, it returns the same height for 'A' and '_'.)

Try and run it it is self describing. :-) Since Alexandre didn't apply the Makefile patch, running it is a little awkwark. Will fix that it later versions though. Try do: cd wine ./tools/winapi/make_filter make You can also give it parameters like ./tools/winapi/make_filter make clean Warning "make clean" doesn't look that good currently. PS. It filters the make messages and only display important messages. It might not always work 100% though, but I will fix problems as I find them. I wrote it many months ago and have run it from time to time since, so most issues have been fixed. The reason I wrote it was that I was irritated that important messages scrolled of screen. > If it's nice isn't it worth advertising to the Wine > developper community? I had intended to do that if but since I was unsure that Alexandre would apply my Makefile patch I decided to wait until it could present a better "user interface". But by all means test it.

It is neither used by Wine, nor defined by Windows. In fact only a few strange headers use volitile at all, and none of them is supported by Wine. > Most of these are because of the transition to making HANDLE a void* > and compiling with STRICT. Yes, I notice this was the case with TIMERPROC casts. However it is no so with the HOOKPROC casts, and yes it is the same with the real Windows headers. > Please don't add typecasts, consider the > warnings as an incentive to do the right fix... As you wish, but as I said HOOKPROC can't be fixed with STRICT. But OK I will try and compile with -DSTRICT and see what happends. IIRC somebody tried that but it didn't turn out so well. Oh well, lets see what happends.

It is not in my Microsoft Visual C++ 6.0 header, but perhaps you have a newer version? DPlay using volatile seems a little strange, so I thought is was wrong especially since it was not in my version, but then I have seen stranger things. :-) > > As you wish, but as I said HOOKPROC can't be fixed with STRICT. > > Why not? Because it would be incompatible (warning wise) with Winelib applications compile with -DSTRICT since Windows doesn't provide a special -DSTRICT version of HOOKPROC. The application might pass a FARPROC to it and expect it to work. Well, of course it works but it would generate a warning.

Why don't you have make_filter call make instead of the other way around? This would avoid the need for changing the makefiles at all. -- Alexandre Julliard julliard(a)winehq.com

Well, make_filter actually calls make already. :-) Seriously, one reason that I added it to the Makefiles in the first place is that make_filter doesn't know what version of make to use. Sure it is called make on almost all systems and gmake (GNU Make) on most of rest, but since the user knows and calls "make", $(MAKE) contains the correct "make". Oh well, I guess just calling make will work on most platforms, it will on all platforms that I current use. The Wine Makefile is supposed to be portable so I guess it will have to do.

No it needs a lot of fixes, which is what the warnings are here to remind us of. -- Alexandre Julliard julliard(a)winehq.com

How do I stop clipping?
by Bill Medland 26 Jul '01

26 Jul '01

I don't like submitting incomplete code but I may have little choice unless someone can point me in the correct direction here. As you may guess from the following, my Windows experience is not that extensive but I think it's enough to allow me to make sensible contributions. I am working on correcting the LISTVIEW_DrawLargeItem function, especially when the item text is large. I have already got most of the way. However the problem is this. When a user selects a large icon the text should be written completely (by calling DrawText with DT_NOCLIP). It is doing so; I can prove it by resizing the window and I will see the full text being displayed for a selected item. However when drawing it at the moment of selecting it, the text is being clipped to the usual two and a bit rows. Presumably this means that there is a clipping rectangle in the DC or the window that I need to inflate. Or Do I simply invalidate that rectangle (from within the WM_PAINT handler!!!). Any help would be appreciated. Bill
