text edit box not painting text ( on form startup )
by Doug Herbert 09 Mar '05

09 Mar '05

( I have posted a similiar question in wine-users, don't flame me for doing so, just thinking about this some more, perhaps it may be more a developer question ) Ok, I have a windows app, that runs under wine fine - not quite. This app has a form, with many text field edit boxes on. Quite often these edit boxes already have text values, ie. they are not empty - there is a database behind the form. Anyway, the form shows on the screen, but the text within the edit fields is invisible, until you activate each edit box component. When you leave one edit box to the next, the text remains visible. It seems like the repainting is not working, on initial startup of the form. As a way to debug this database app ( I don't have the source code for it ) I wrote a real basic form app in Visual Studio, with two edit boxes, with data in each. Now this basic app shows the text values immediately on startup. So there must be something different that the database app is not doing. I then ran wine using 'wine --debugmsg +edit programname' for both app's. I see both logging 'Creating ANSI edit control, style = xxxxx' but the style reference is different between apps - I am not sure if this the cause or not. The problem app reports style = 54011104 and the basic app shows style = 50010080. Can somebody explain what this style reference means and how do I force an app to use a certain style of edit box ? What other wine class debugmsg types should I use to narrow down the source of this problem ? Is there anyway I can check to see how the database app is repainting text within the text edit components ? Regards Doug Herbert. __________________________________ Do you Yahoo!? Yahoo!

MinGW cross compilation enviroment setup
by Michael Stefaniuc 20 Feb '04

20 Feb '04

Hello! Here are the steps needed to setup a MinGW on a Red Hat Linux like rpm based system (Fedora Core, Mandrake Linux, ... should probably work even on a SuSE Linux) * Download the mingw-binutils and mingw-gcc srpm's from http://ftp.redhat.com/pub/contrib/libc6/SRPMS/ * Download the mingw-3.0-1.src.rpm srpm from http://ftp.redhat.com/pub/contrib/libc6/noarch/SRPMS/ * Build the mingw and mingw-binutils rpm's (rpmbuild --rebuild $SRPM) and install them. * After the above step you can build the mingw-gcc rpm too. Install it. * That's almost everything: you need this patch for wine's configure to make it find your mingw binaries. * For instructions how to build the Wine tests for Windows see the Wine Documentation. You may want to try your local Red Hat mirror for the above srpm's. This info can be found also on http://people.redhat.com/mstefani/wine/ Hope this helps bye michael -- Michael Stefaniuc Tel.: +49-711-96437-199 System Administration Fax.: +49-711-96437-111 Red Hat GmbH Email: mstefani(a)redhat.com Hauptstaetterstr. 58 http://www.redhat.de/ D-70178 Stuttgart

[ddraw] asynchronous screen updates
by Piotr Pawlow 05 Feb '04

05 Feb '04

If DGA is not available, Wine falls back to creating offscreen primary surface and blitting all changes to the screen. It knows which part of the surface might have changed by watching unlock calls. However, as Jukka Heinonen pointed out in his message posted on 17.10.2001, the update logic in asynchronous mode (when SYNC_UPDATE is not defined, which is the default) is broken: "(...)if more than one lock/unlock pair happens between update thread blits, display might not be updated correctly". Synchronous mode on the other hand, causes applications, which constantly lock and unlock big areas just to change a few pixels, run very slow. As this bug prevents me from playing "Warlords: Battlecry", I decided to do something about it. Here are my changes: - User_add_dirty_rect is now an asynchronous equivalent of User_copy_to_screen. It adds the rectangle to the list of dirty rectangles and signal the update thread that there is some work to do. - update thread calls User_get_dirty_rect to iterate over the list of dirty rectangles - current "naïve" algoritm keeps only one rectangle which is a union of all dirty rectangles, so it tends to redraw too much, but better algoritms may be implemented - removed now unused lastlockrect variable, and the code which updates it I attached the patch for your reviews, comments, suggestions. The game is almost playable now, there are remaining issues with DirectMusic (must be run with NODIRECTMUSIC switch or crashes) and windows managers (kwin cannot raise the window, metacity complains that the window attributes do not make sense). -- Piotr Pawlow mailto:pp(a)siedziba.pl

DIB_DirectDrawSurface_BltFast signed/unsigned comparision bug
by Piotr Pawlow 05 Feb '04

05 Feb '04

Hello, I spotted this bug while trying to fix mouse pointer trails problem in Warlords Battlecry. All widths, heights and left/top coordinates are of DWORD type, so substracting them from each other always give positive numbers. Thus h and w are always >= 0, so DDERR_INVALIDRECT is returned only in a couple of boundary cases. I just added explicit casting to int where needed. It didn't fix the mouse trails, but previously missing mouseover effect on icons at the main screen appeared, so I guess it is a change in the right direction :) Patch attached.

Mouse up vs Mouse click
by Fabian Cenedese 04 Feb '04

04 Feb '04

Hi Where is decided if I release the mouse button if a mouse up or a mouse click is generated? Is this time dependent? Or generally the same? The misbehaving app uses a ownerdrawn, CListCtrl-derived list. When I click on a cell not in the first column the cell gets selected. But on wine I can see that the selection flashes shortly and disappears right again (Surprisingly it works when I click in the first column. As my application uses the same code for all columns it must be something else.). After putting some debug messages in my code I found that on Windows after the left-button-down event a left-button-click event is generated, no matter how long I hold the button before releasing. On wine there is no click event but a mouse up event. And the cell flashes even when I hold the button, so it's not the releasing itself that clears the selection. The control is a bit quirky with moving focus around and handling events specially. But still it works on Windows :) Now I'm a bit lost how I can debug this. +mouse didn't show anything usefull. I guess the generating and sending of the events is done in the wineserver. Thankful for any hints. bye Fabi

TransparentBlt
by Kevin Koltzau 02 Feb '04

02 Feb '04

Implementation of TransparentBlt This brings up an interesting thing however..it works perfectly under windows (tested on XP), but produces strange results under wine. MaskBlt seems to be broken, but I'm not quite sure what the cause is yet I figured I'd send this out incase the problem is obvious to anyone

Maybe so, but it looks obviously incorrect. Not everything that seems to fix problems is a real fix. You maybe hiding a bigger issue. The fix as you sent it can't be right, but you maybe on to something. Someone knowledgable in the area should express a more informed opinion. -- Dimi.

Hel debugging windows app with wine(dbg) + gdb
by Leo 31 Jan '04

31 Jan '04

Hi, I don't know if this is the place to ask this, but anyway here it goes: I'm trying to debug a windows application using wine. The app is compiled with mingw (www.mingw.org) and I tried using -gstabs and -ggdb debug info but same problem happens. The problem is: 1) Using winedbg as server for remote gdb debugger, when execution stops (sigfault, or whatever), and I type 'bt' in the gdb client, no debug info is shown, just lines like this one: #0 0xdeaf1005 in ?? () 2) Running 'wine <myapp.exe>' and then using gdb client to debug the process with the 'attach' command, when execution stops (sigfault, or whatever), and I type 'bt' in the gdb client, debug info IS shown, but line numbering shows always just the first line in the function. For example, say I have this function: void f() { int a=123; *(char *)0=a; } then when sigfault is caught, gdb shows backtrace like this: #0 0x0040130b in f() () at f.cpp:2 even though exception occurs in line 4. Either way, I can't debug a windows app correctly. May I be doing something wrong. I've read the docs and followed instructions for DDD, KDbg, and just plain gbd. I'm using latest wine 2004 rpm under Redhat 9. Any help greatly appreciated. Thanks, Leo.
