Hello, WINE developers!
While working on a cross-platform project, I tried to run some self-compiled GTK/W32 applications on a Debian GNU/Linux Sarge system using WINE 0.9.29, compiled from source. They crashed immediately.
After some long, but unsuccessful Google sessions and some long, but successful RTFS/debugging sessions, I am now able to run and test my cross-compiled GTK/W32 applications in WINE. :-)
Furthermore, I can start the W32 version of The GIMP up to the moment where it tries to load its plug-ins. (Without the plug-ins, the remaining parts of The GIMP even seem to work flawlessly.)
Since Google told me that running GTK/W32 applications in WiNE - in particular: The GIMP - was an unsolved problem, I am hereby telling you what I observed and what I did.
* Out of the box, pango (GTK's font renderer) does not find any suitable font.
OTOH a non-GTK program, opening a MessageBox, works flawlessly, so the fonts are there.
* When I tell pango to use a TrueType font *and* place the .ttf file in c:/windows/fonts/, I can start GTK's "Hello, world!" program, but the text is >300 pixels high, and thus unusable.
(Real-world programs used to crash with a message similar to "memory exhausted", but trying to reproduce the exact message now results in *running* programs with a giant font. Sorry.)
I conclude that (at least in my installation) pango does not find WINE's pixel fonts (even if I place them in c:/windows/fonts/), and sees the TTFs only with a wrong scaling factor.
* When I tell pango to use the font "Sans 0.1", I get satisfying results.
(In concrete, I got it working with the following gtkrc:
style "wine-default-style" { font_name = "Sans 0.1" }
widget "*" style "wine-default-style"
)
I cannot fine-tune the font size. Using "Sans 0.2" or "Sans 0.01" yields exactly the same as "Sans 0.1". There seems to be one more intermediate size at "Sans 0.5"; after that the "normal" font sizes start with "Sans 1".
Since both WINE and pango/GTK are free software, I am confident that these problems will be solved in the long run. I hope that you can use my observations.
BTW, let me thank you for over 10 years of WINE by hacking Tom Payne's famous quote on Unix:
Ten years ago mainstream users were choosing WABI over WINE. Now they are choosing $PROPRIETARY_FORK_OF_WINE over WINE. What part of that message aren't they getting?
Keep on your excellent work!
Cheers,
Peter

Thank you for your elaborate diagnosis. This is probably related to the problem Mono has on Wine because it also uses Pango/GTK. Does it help if you install MS core fonts?

It would be good if you could put your findings in a bug in Bugzilla (there may already exist a bug for this, otherwise you can open a new one).

I tried, but it did not help.

Hello!
Thank you for your elaborate diagnosis. This is probably related to the problem Mono has on Wine because it also uses Pango/GTK.
It seems as if this is not a problem with GTK or Pango but with cairo. GTK-2.6 (without cairo) works fine on wine. Here is a minimal cairo-win32 example basing uppon code from Owen Taylor:
/* * This example code is placed in the public domain * * Author: Owen Taylor otaylor@redhat.com, Red Hat Inc. */
#include <cairo-win32.h>
#define TITLE TEXT("Cairo test") #define BORDER_WIDTH 75. #define SNIPPET_WIDTH 300. #define SNIPPET_HEIGHT 300. #define FONT_SIZE 24
static void on_paint (HDC hdc) { cairo_surface_t *surface; cairo_t *cr; double line_width; cairo_font_extents_t font_extents;
surface = cairo_win32_surface_create (hdc); cr = cairo_create (surface);
line_width = cairo_get_line_width (cr);
/* Draw a box bordering the snippet */ cairo_rectangle (cr, BORDER_WIDTH - line_width / 2, BORDER_WIDTH - line_width / 2, SNIPPET_WIDTH + line_width, SNIPPET_WIDTH + line_width); cairo_stroke (cr);
/* And some text */ cairo_select_font_face (cr, "Arial", CAIRO_FONT_SLANT_NORMAL, CAIRO_FONT_WEIGHT_BOLD); cairo_set_font_size (cr, FONT_SIZE); cairo_font_extents (cr, &font_extents);
cairo_move_to (cr, BORDER_WIDTH, BORDER_WIDTH + SNIPPET_WIDTH + font_extents.ascent); cairo_show_text (cr, "This is some example text!");
cairo_destroy (cr); cairo_surface_destroy (surface); }
/* The WinMain and window procedure are loosely based on a example * from the Microsoft documentation. */ LRESULT CALLBACK WndProc (HWND window, UINT message, WPARAM wParam, LPARAM lParam) { PAINTSTRUCT paint_struct; HDC dc;

return DefWindowProc (window, message, wParam, lParam); }

window = CreateWindow (TITLE, /* Class name */ TITLE, /* Window name */ WINDOW_STYLE, CW_USEDEFAULT, CW_USEDEFAULT, /* initial position */ rect.right - rect.left, rect.bottom - rect.top, /* initial size */ NULL, /* Parent */ NULL, /* Menu */ hInstance, NULL); /* WM_CREATE lpParam */
ShowWindow (window, iCmdShow); UpdateWindow (window);
while (GetMessage (&message, NULL, 0, 0)) { TranslateMessage (&message); DispatchMessage (&message); }
return message.wParam; }
