GtkFixed implements
GtkBuildable
and AtkImplementorIface.
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.
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:
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.
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.
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.
GtkFixed
GtkFixed
struct contains the following fields.
(These fields should be considered read-only. They should never be set by
an application.)
list *children; | a list of GtkFixedChild elements, containing the child widgets and their positions. |
GtkFixedChild
GtkFixedChild
struct contains the following fields.
(These fields should be considered read-only. They should never be set by
an application.)
GtkWidget *widget; | the child GtkWidget . |
integer x; | the horizontal position of the widget within the GtkFixed container. |
integer y; | the vertical position of the widget within the GtkFixed container. |
gtkFixed
is the equivalent of gtkFixedNew
.
