Adding Entry into a MenuItem
Hi, I am working on streamlining my Gtk-Application for faster use. It is currently running inside a StatusIcon and showing up a Menu right clicking on it. Here the user shall enter a String for before starting an action, for example a Search-Pattern before searching. It seems not to be a problem to add a Entry into a MenuItem (since it's derived from Bin); but no keyboard events come to the Entry. Actually no key events come to the MenuItem itself. How can I make this Entryfield editable? Or is it impossible by design to add Entries to Menus? I am using Gtkmm.

Utf8 strings manipulation
Hi all, I'm trying to transform an utf8 string. I have some problems with it because I don't know how to do it or where I can see an example (a tutorial, doc or application). I need transform this text (in utf8): gtk_source_completion to: GtkSourceCompletion. I don't know how replace a character or delete a character. Perhaps I need to allocate a gchar* array first and then use g_utf8_strncpy in all _, I don't know. In that case, I don't know how much memory I need to allocate. Can you help me?

Re: Transparent Draw Area
You can not make widgets transparent, other than to the other windows/desktop. Thus in your case, you need to create a new gtk.Window, and lay it over the rest of your app. You use the POPUP flag to remove the window-border and some set_colormap(self.get_screen().get_rgba_colormap()) If you read python, you can look in the beginning of: http://code.google.com/p/pychess/source/browse/trunk/lib/pychess/widgets/pydock/OverlayWindow.py fre, 26 09 2008 kl. 13:41 +0200, skrev michael: Hi all, I want to create a transparent draw area and using cairo to draw line with the window background.

Re: Utf8 strings manipulation
Hello,
what I would do (not necessarily the smartest thing;) is try to
determine what strings I'll be operating on. If I'm operating on
ANSI/iso8859-1 strings, I don't need to use uft8-specialized
functions, since characters from those have the same codes in all
encodings.
That thing out of the way, we can go and convert our string. I would
do it with glib's string manipulation functions like this (example
only):
CODE ==
#include glib.h
#include string.h
#include stdio.h
int
main( int argc, char **argv )
{
gchar *string = gtk_source_completion;
gchar *string_new;
gchar **parts;
gchar **parts_bk;
printf( %s\n, string );
parts = g_strsplit( string, _, -1 );
parts_bk = parts;
for( parts; parts; parts++ )
{
gchar *tmp;
tmp = g_utf8_strup( *parts, ( g_utf8_next_char( *parts ) -
*parts ) * sizeof( gchar ) );
memcpy( *parts, tmp, strlen( tmp ) );
g_free( tmp );
}
string_new = g_strjoinv( NULL, parts_bk );
g_strfreev( parts_bk );
printf( %s\n, string_new );
return( 0 );
}
/CODE =
Hope it's been helpfull.

Re: Transparent Draw Area
Hi,
for now I do it:
Change the window expose event:
static gboolean
window_expose_event (GtkWidget *widget,
GdkEventExpose *event)
{
GdkRegion *region;
GtkWidget *child;
cairo_t *cr;
/* get our child (in this case, the draw area) */
child = gtk_bin_get_child (GTK_BIN (widget));
/* create a cairo context to draw to the window */
cr = gdk_cairo_create (widget-window);
/* the source data is the (composited) event box */
gdk_cairo_set_source_pixmap (cr, child-window,
child-allocation.x,
child-allocation.y);
/* draw no more than our expose event intersects our child */
region = gdk_region_rectangle (child-allocation);
gdk_region_intersect (region, event-region);
gdk_cairo_region (cr, region);
cairo_clip (cr);
/* composite, with a 50% opacity */
cairo_set_operator (cr, CAIRO_OPERATOR_OVER);
cairo_paint_with_alpha (cr, 1);
/* we're done */
cairo_destroy (cr);
return FALSE;
}
To take the region of the child.
And in the event of the draw area do it:
static gboolean
on_expose_event(GtkWidget *widget,
GdkEventExpose *event,
gpointer data)
{
struct GraphConf *conf = (struct GraphConf *)data;
cairo_t *cr;
cairo_pattern_t *pat1, *pat2, *pat3, *pat4;
cr = gdk_cairo_create(widget-window);
cairo_set_operator (cr, CAIRO_OPERATOR_CLEAR);
gdk_cairo_region (cr, event-region);
...
Then write what do you want...
And initialize all like this:
My window background is a castle. I can see the cairo graph
over a castle.
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_widget_set_style(GTK_WIDGET(window), GTK_STYLE(style));
darea = gtk_drawing_area_new();
screen = gtk_widget_get_screen(darea);
rgba = gdk_screen_get_rgba_colormap(screen);
gtk_widget_set_colormap(darea, rgba);
gtk_widget_set_app_paintable (GTK_WIDGET (darea), TRUE);
gtk_container_add(GTK_CONTAINER (window), darea);
gtk_widget_show(darea);
init_graph_conf(gconf);
g_signal_connect(window, destroy,
G_CALLBACK(gtk_main_quit), NULL);
g_signal_connect(darea, expose-event,
G_CALLBACK(on_expose_event), gconf);
gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
gtk_window_set_default_size(GTK_WINDOW(window), 320, 400);
gtk_window_set_title(GTK_WINDOW(window), Temperature);
gtk_widget_show_all(window);
gdk_window_set_composited (darea-window, TRUE);
g_signal_connect_after(window, expose-event,
G_CALLBACK(window_expose_event), NULL);

Thanks a lot Tadej!!
I will try this to learn more about utf8 string manipulation but I will
use regexp because I need to replace more characters (This is only an
example)

Composite children
I surround the creation of a particular widget with widget_push_composite_child and widget_pop_composite_child. Afterward, I see that property composite-child is True for the new widget. However, when I run get_children on the parent, the widget appears in the list even though documentation says that get_children returns the container's non-internal children.
