Detailed Description

A container which allows you to position widgets at fixed coordinates.

The Gtk::Fixed widget is a container which can place child widgets at fixed positions and with fixed sizes, given in pixels. It performs no automatic layout management. For most applications, you should not use this container, because it will result in truncated text, overlapping widgets, and other display bugs:

  • Themes may change widget sizes.
  • 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.
  • Translation of text into other languages changes its size. Also, display of non-English text will use a different font in many cases. 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 Gtk::Fixed. 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 Gtk::Fixed, by all means use the widget. But you should be aware of the tradeoffs.

Member Function Documentation

bool Gtk::Fixed::get_has_window (   const
 

Gets whether the Gtk::Fixed has it's own Gdk::Window.

See gdk_fixed_set_has_window().

Returns:
true if fixed has its own window.

const GtkFixed* Gtk::Fixed::gobj (   const [inline]
 

Reimplemented from Gtk::Container.

GtkFixed* Gtk::Fixed::gobj (   [inline]
 

Reimplemented from Gtk::Container.

void Gtk::Fixed::move ( Widget   widget,
int    x,
int    y
 

void Gtk::Fixed::put ( Widget   widget,
int    x,
int    y
 

void Gtk::Fixed::set_has_window ( bool    has_window = true
 

Sets whether a Gtk::Fixed widget is created with a separate Gdk::Window for widget->window or not.

(By default, it will be created with no separate Gdk::Window). This function must be called while the Gtk::Fixed is not realized, for instance, immediately after the window is created.

Parameters:
has_window true if a separate window should be created.
