What could be?
Thanks

This happens because your original "pixbuf"  is a global object, remove the 
first of the three _unref and you should be fine!

Ah, that must be it, yes. I use gtk_image_new_from_icon_name() for menu
icons, and now that you mention it these indeed do not show up. So,
that must be where it tries to use the 'image-missing' icon. Thanks, I
guess I'll just have to accept that menu items really can no longer
have icons. Thanks for the reply.

Best regards,
Norbert

Re: Fwd: Resize and place a background image (Expose Event)

[Rúben Rodrigues]

Thank you very much!!

I'm not sure if i have to do this every time an expose event occurs.. I 
think that i just need on start of application.. But i test on start of 
application, i i don't have widget->allocation values, to make the resize..

Now, application crash after start, but i think that is because i make 
the unref of pixbuf, and in next expose event, fails (i think)...

GdkPixbuf-CRITICAL **: gdk_pixbuf_scale_simple: assertion 'GDK_IS_PIXBUF

Re: win32 (via Wine): 'image-missing' not present in theme Adwaita

[Code Musings]

Hello Norbert,

which GTK version are you porting to and what is the call you’re using that 
causes the GTK Warning about the missing icon? I don’t have a Windows machine 
but the 'image-missing' icon is definitely present on my machine (I checked 
using gtk3-icon-browser).

Also the all the *-from-stock (e.g. gtk_button_new_from_stock) functions have 
been deprecated in GTK 3.10 so maybe that’s the issue?

Fwd: Resize and place a background image (Expose Event)

[Gabriele Greco]

>
> This works, but application blocks after a while..

I'm quite sure the problem is that you are leaking at least 2 pixbuf and a
pixmap for every expose event your app receives, and anyway, are you sure
you have to do it every time an expose event is thrown and not only when
the window is resized (configure_event)?


>
>

>

If the original pixbuf has been created just for this operation, this call
leaks a pixbuf object, you shoud do something like:

GdkPixbuf *scaled = gdk_pixbuf_scale_simple(pixbuf,
widget->allocation.width, [...]
g_object_unref(pixbuf);


> widget->allocation.height, GDK_INTERP_BILINEAR);
>  gdk_pixbuf_render_pixmap_and_mask (pixbuf, , NULL, 0);
>

At this point you leak the second pixbuf, use for instance:
g_object_unref(scaled);


>  style->bg_pixmap[0] = background;
>  gtk_widget_set_style (GTK_WIDGET(widget), GTK_STYLE(style));

I'm quite sure set_style will increase reference count for 'background', so
after this call you should unref that pixmap:

g_object_unref(background);

You'll receive runtime errors if one of my statements here is not correct,
it's better to add a not needed unref in development and fix it that
release a version that leaks memory.

Glade crash

[pozzugno]

Most probably this isn't the most appropriate mailing list, because I 
think my issue is related to Glade (and not Gtk libraries).


Attached is one of my graphical interface, designed with Glade. 
Unfortunately when Glade opens this file, it seems it is very unstable 
if I try to change something.


For example, let's try to delete the row in the fans_store GtkListStore 
object. Glade 3.20 will crash (at least in Windows).


Do you understand why? I tried many things, even editing manually the 
.glade file with a text-editor. Many times, Glade wil crash during 
opening the edited file.

Re: Resize and place a background image (Expose Event)

[Rúben Rodrigues]

Hi,

I have made progress, i use this function to make the resize: pixbuf = 
gdk_pixbuf_scale_simple(pixbuf, widget->allocation.width, 
widget->allocation.height, GDK_INTERP_BILINEAR);

This works, but application blocks after a while..

Here is the Expose event function:

void on_layout_Home_expose_event(GtkWidget *widget, GdkEvent *event, 
gpointer   user_data){
 GtkAllocation allocation;
 GtkWidget*homeWindow;
 GdkPixmap*background;
 GtkStyle*style;

 pixbuf = gdk_pixbuf_scale_simple(pixbuf, widget->allocation.width, 
widget->allocation.height, GDK_INTERP_BILINEAR);
 gdk_pixbuf_render_pixmap_and_mask (pixbuf, , NULL, 0);
 style = gtk_style_new ();

 style->bg_pixmap[0] = background;
 gtk_widget_set_style (GTK_WIDGET(widget), GTK_STYLE(style));

 return TRUE;

}

Thanks
