using cairo surfaces
Hello. I'm trying to create a custom container widget that holds the child widgets in a hbox (or scrollarea, after I learn how to use it). The child widgets are using cairo for the drawing, and so is the container widget. I want to optimize the container drawing since the child widgets don't always need complete redrawing. The child drawing is currently done to the container's cairo surface, which is passed to each child widget, and childs draw to this surface. Reference to this surface is stored and I'm using a private variable in the container widget that keeps track of whether the childs need full redraw or can I use the stored surface to do quick redraw without the need to call the childs' drawing functions. Now, I want the child widgets to have their own surfaces and each child should handle the smart drawing. So the child widget decides whether it uses the previously rendered surface or redraws some parts. The container then just uses set_source_surface to draw the child at desired position. What kind of surface I should create in the child widgets and how do I copy it to the container surface? I've tried creating image surface, but I guess I was doing something wrong, because nothing was drawn, or I got segfault. So I still have not found the right way of doing it. The documentation is lacking examples, so I have proceeded in trial and error-basis, and now I'm kind of stuck.

Obtaining area needed to render a text
I am developing an application where I need to render some objects in a DrawingArea, among with them are some text labels. I'd like to know in advance how much area (width/height) would be needed to render a text. Also, I am using cairo to render. Anyway, thanks for the attention. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

how to set a plain colour in a GtkImage
Hi, I have a GtkImage which, in some cases, I need to set to the to a plain colour (e.g. set it entirely to yellow). I couldn't find any function in GdkPixbuf GTK API to do it... What's the smartest way to do it ? Thanks!

GIOChannel and win32?
Hi! Some time ago I created a thread on this mailing list and someone (I don't remember his name now) said, that he read on GTK+ devel list, that GIOChannel may not work under the Microsoft Windows? Is that true, or not? -- Pozdrawiam! Tom ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

This is not the smartest way to do it, especially if the images can be large, but it's typically the most straightforward way.

Help with a variable in a .pc file
Hi all
Could any help me on how to get a variable value in a .pc file?
I have the following values in the glade-3.pc file:
catalogdir=${prefix}/share/glade3/catalogs
pixmapdir=${prefix}/share/glade3/pixmaps
moduledir=${exec_prefix}/lib/glade3/modules
I need this variables in order to install the compiled and support files in
the correct plase to allow glade3 to find them.
At moment I try in configure.in to use the following sentences:
AC_SUBST(GLADE3_PIXMAP_DIR, '[$(shell pkg-config --variable=pixmapdir
glade-3)]')
AC_SUBST(GLADE3_MODULES_DIR, '[$(shell pkg-config --variable=moduledir
glade-3)]')
AC_SUBST(GLADE3_CATALOG_DIR, '[$(shell pkg-config --variable=catalogdir
glade-3)]')
But it doesn't compile the sources in the glade directory.
Note that in configure I set the AC_OUTPUT to point to the glade directory,
./configure is generating the Makefiles but never compiles them. In the
glade/Makefile.am I have:
@INTLTOOL_XML_NOMERGE_RULE@
catalogsdir = $(GLADE3_CATALOG_DIR)
catalogs_DATA = gnomedb.xml gnomedb.xml.in
EXTRA_DIST = \
$(catalogs_DATA)
INCLUDES = \
-g -Wall \
-I$(top_srcdir)\
-I$(top_builddir)\
-DG_LOG_DOMAIN=\GnomeDB\ \
$(LIBGNOMEDB_CFLAGS) \
$(WITHGNOME_CFLAGS)\
$(GLADE3_CFLAGS)
gladegnomedb_LTLIBRARIES = libgladegnomedb.la
gladegnomedbdir = $(GLADE3_MODULES_DIR)
libgladegnomedb_la_LIBADD = $(top_builddir)/libgnomedb/libgnomedb-3.la \
$(LIBGNOMEDB_LIBS) $(WITHGNOME_LIBS)
$(GLADE3_LIBS)
libgladegnomedb_la_LDFLAGS = -module -avoid-version
libgladegnomedb_la_SOURCES = glade-gnomedb.c
