* gtk/gtklabel.c (gtk_label_ensure_layout): Set
the width of the layout to the actual wrap width
(our requisition) not the width we set when calculating
the width. This results in the lines being justified
within the correct area. (#79157, Anders Carlsson)
* gtk/gtkaccelgroup.c gtk/gtkmarshelers.list: Corrected
registered parameter types of "accel_activate" and
"accel_changed" signals. (Patch from Murray Cumming, #78798)
* gtk/gtkrc.c (gtk_rc_make_default_dir): Switch
binary-version and type to correspond to the
current ordering in _gtk_get_module_path.
(#78746, Sergey Kuzminov)
* gtk/gtkrc.c (gtk_rc_get_module_dir): Add docs
pointing to the GTK_PATH documentation.
* gtk/Makefile.am (uninstall-local): Delete
key themes as well. (#81286, Kristian Rietveld.)

GtkFixed
|
|
|
|
<!-- ##### SECTION Short_Description ##### -->
|
|
a container which allows you to position widgets at fixed coordinates
|
|

<para>
|
|
The #GtkFixed widget is a container which can place child widgets at fixed
|
|
positions and with fixed sizes, given in pixels. #GtkFixed performs no
|
|
automatic layout management.
|
|
</para>

<para>

|
For most applications, you should not use this container! It keeps
|
|
you from having to learn about the other GTK+ containers, but it
|
|
results in broken applications.
|
|
With #GtkFixed, the following things will result in truncated text,
|
|
overlapping widgets, and other display bugs:
|
|
<itemizedlist>
|
|
<listitem>
|
|
<para>Themes, which may change widget sizes.
|
|
</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>Fonts other than the one you used to write the app will of
|
|
course change the size of widgets containing text; keep in mind that
|
|
users may use a larger font because of difficulty reading the default,
|
|
or they may be using Windows or the framebuffer port of GTK+, where
|
|
different fonts are available.
|
|
</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>
|
|
Translation of text into other languages changes its size. Also,
|
|
display of non-English text will use a different font in many cases.
|
|
</para>
|
|
</listitem>
|
|
</itemizedlist>
|
|
</para>
|
|
|
|
<para>
|
|
In addition, the fixed widget can't properly be mirrored in
|
|
right-to-left languages such as Hebrew and Arabic. i.e. normally GTK+
|
|
will flip the interface to put labels to the right of the thing they
|
|
label, but it can't do that with #GtkFixed. So your application will
|
|
not be usable in right-to-left languages.
|
|
</para>
|
|
|
|
<para>
|
|
Finally, fixed positioning makes it kind of annoying to add/remove GUI
|
|
elements, since you have to reposition all the other elements. This is
|
|
a long-term maintenance problem for your application.
|
|
</para>
|
|
|
|
<para>
|
|
If you know none of these things are an issue for your application,
|
|
and prefer the simplicity of #GtkFixed, by all means use the
|
|
widget. But you should be aware of the tradeoffs.
