Description

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.

Details

struct GtkFixed

struct GtkFixed;

The GtkFixed struct contains the following fields. (These fields should be considered read-only. They should never be set by an application.)


struct GtkFixedChild

struct GtkFixedChild
{
  GtkWidget *widget;
  gint x;
  gint y;
};

The GtkFixedChild struct contains the following fields. (These fields should be considered read-only. They should never be set by an application.)


gtk_fixed_new ()

GtkWidget*  gtk_fixed_new                   (void);

Creates a new GtkFixed.


gtk_fixed_put ()

void        gtk_fixed_put                   (GtkFixed *fixed,
                                             GtkWidget *widget,
                                             gint x,
                                             gint y);

Adds a widget to a GtkFixed container at the given position.


gtk_fixed_move ()

void        gtk_fixed_move                  (GtkFixed *fixed,
                                             GtkWidget *widget,
                                             gint x,
                                             gint y);

Moves a child of a GtkFixed container to the given position.


gtk_fixed_get_has_window ()

gboolean    gtk_fixed_get_has_window        (GtkFixed *fixed);

Gets whether the GtkFixed has it's own GdkWindow. See gdk_fixed_set_has_window().


gtk_fixed_set_has_window ()

void        gtk_fixed_set_has_window        (GtkFixed *fixed,
                                             gboolean has_window);

Sets whether a GtkFixed widget is created with a separate GdkWindow for widget->window or not. (By default, it will be created with no separate GdkWindow). This function must be called while the GtkFixed is not realized, for instance, immediately after the window is created.
