Re: How to set background color for a pango layout being printed ?
Unfortunately, this does not work. All I get is a page that is completely
empty (white).
My requirements are not to paint entire background of a page in one color,
but to paint the background of the single text layout in that color.
Each page has more than one text layout being drawn with the different
properties
(color, bgcolor, font, bold, italic, ...).
Yesterday I've found some code (see below) that should work but it doesn't
work all the time.
On Ubuntu 7.04 (PDF backend), background color works fine, text underlining
woks, but the text is underlined with gray color!, strikethrough does not
work at all!
On Windows (GTK+ 2.10.11 from http://gladewin32.sourceforge.net/),
when using print preview operation (.emf image format) everything seems to
work,
but I get strange drawing artefacts in the picture.
Individual text layouts are drawn with gray lines either on the left and
right layout bounds or on the
top and bottom bounds!! Some layouts are even completely squared in gray.
You can see the sample for Windows print preview at:
http://notecase.sourceforge.net/temp/printing.jpg
Even more strange, when I print the same test page on the actual printer
(Windows),
there are no gray lines and everything works except the strikethrough (there
is no strike line).
My new code is this:
//create layout
layout = gtk_print_context_create_pango_layout (context);
pango_layout_set_text (layout, text, -1);
//set required layout attributes
PangoAttrList *layout_attr = pango_attr_list_new ();
PangoAttribute *attr1 = pango_attr_background_new(bkgcolor.red,
bkgcolor.green, bkgcolor.blue);
pango_attr_list_insert (layout_attr, attr1);
if(bStrike){
PangoAttribute *attr2 = pango_attr_strikethrough_new (TRUE);
pango_attr_list_insert (layout_attr, attr2);
}
if(bUnderline){
PangoAttribute *attr3 =
pango_attr_underline_new(PANGO_UNDERLINE_SINGLE);
pango_attr_list_insert (layout_attr, attr3);
}
pango_layout_set_attributes(layout, layout_attr);
pango_layout_context_changed(layout);
//set fg color
cairo_set_source_rgb (cr, color.red, color.green, color.blue);
cairo_move_to (cr, nPosX, nPosY);
pango_cairo_show_layout (cr, layout);
Does anyone knows what is the problem with this ? Is this a GTK bug ?
Is it the code problem ?

Miroslav

window and widget resize
Hi again ;-) I have that interface: +---+ | +---+ | | | | | | | Widget 1| | | | | | | +---+ | | +---+ | | | | | | | Widget 2| | | | | | | +---+ | +---+ After I'm resizing window, my program looks like: +---+ | +---+ | | | | | | | Widget 1| | | | | | | +---+ | | +---+ | | | | | | | Widget 2| | | | | | | +---+ | | | |Blank Space| | | +---+ How to auto resize widget, that they fit window? I think, that it's not only my problem, so I think, that you know solution. First of all, I tried to use size-allocate signal on main window. but, it's not so beautiful, like I want.

let g_warn_if_fail replace g_assert
hey All. proposing to turn g_asert into a warning: http://mail.gnome.org/archives/gtk-devel-list/2007-October/msg00053.html was obviously not perceived too well. as i read it, most people are not against my basic reasoning, but are clearly in favour of adding g_warn_if_fail or a similar variant thereof. so i'd like to change course and suggest we do this: - add g_warn_if_fail (condition); which produces a critical warning about failing assertions but contrary to g_assert returns. - extend the g_assert() docs to note that: 1) programmers are more likely to want to use g_warn_if_fail instead (particularly for libraries, allthough the destabilizing effects of g_assert are also worth avoiding in applicaiton code); 2) for code portions that positively have to rely on program termination, only g_error() will deterministically achive that. - proceed analogously for g_warn_if_reached() and g_assert_not_reached(). comments apprechiated, particularly on the new function names. --- ciaoTJ ___ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list

If it's called g_warn_if_fail() I would expect a g_warning() not a g_critical(). Agreed -- and of course g_return_if_fail() does a g_warning(), so doing a g_warning() on g_warn_if_fail() is kinda redundant. How about g_critical_if_fail()? It's a shame tho that we can't encode the it returns if it fails behavior in the name as well -- g_return_if_fail() is very clear what it does (IMO, the fact that it also does a g_warning() is a debugging-related bonus, not its primary purpose). g_critical_if_fail() sorta sounds like all it does is do a g_critical() if the condition fails, and then continues on from that point. I suppose g_critical_return_if_fail() is a bit verbose (esp. when you consider g_critical_return_val_if_fail() is even longer). But I guess good API docs will suffice ^_^. -brian ___ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list
