/**
* GtkWidget is the base class all widgets in GTK+ derive from. It manages the
* widget lifecycle, states and style.
*
* # Height-for-width Geometry Management # {#geometry-management}
*
* GTK+ uses a height-for-width (and width-for-height) geometry management
* system. Height-for-width means that a widget can change how much
* vertical space it needs, depending on the amount of horizontal space
* that it is given (and similar for width-for-height). The most common
* example is a label that reflows to fill up the available width, wraps
* to fewer lines, and therefore needs less height.
*
* Height-for-width geometry management is implemented in GTK+ by way
* of five virtual methods:
*
* - #GtkWidgetClass.get_request_mode()
* - #GtkWidgetClass.get_preferred_width()
* - #GtkWidgetClass.get_preferred_height()
* - #GtkWidgetClass.get_preferred_height_for_width()
* - #GtkWidgetClass.get_preferred_width_for_height()
* - #GtkWidgetClass.get_preferred_height_and_baseline_for_width()
*
* There are some important things to keep in mind when implementing
* height-for-width and when using it in container implementations.
*
* The geometry management system will query a widget hierarchy in
* only one orientation at a time. When widgets are initially queried
* for their minimum sizes it is generally done in two initial passes
* in the #GtkSizeRequestMode chosen by the toplevel.
*
* For example, when queried in the normal
* %GTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH mode:
* First, the default minimum and natural width for each widget
* in the interface will be computed using gtk_widget_get_preferred_width().
* Because the preferred widths for each container depend on the preferred
* widths of their children, this information propagates up the hierarchy,
* and finally a minimum and natural width is determined for the entire
* toplevel. Next, the toplevel will use the minimum width to query for the
* minimum height contextual to that width using
* gtk_widget_get_preferred_height_for_width(), which will also be a highly
* recursive operation. The minimum height for the minimum width is normally
* used to set the minimum size constraint on the toplevel
* (unless gtk_window_set_geometry_hints() is explicitly used instead).
*
* After the toplevel window has initially requested its size in both
* dimensions it can go on to allocate itself a reasonable size (or a size
* previously specified with gtk_window_set_default_size()). During the
* recursive allocation process it’s important to note that request cycles
* will be recursively executed while container widgets allocate their children.
* Each container widget, once allocated a size, will go on to first share the
* space in one orientation among its children and then request each child's
* height for its target allocated width or its width for allocated height,
* depending. In this way a #GtkWidget will typically be requested its size
* a number of times before actually being allocated a size. The size a
* widget is finally allocated can of course differ from the size it has
* requested. For this reason, #GtkWidget caches a small number of results
* to avoid re-querying for the same sizes in one allocation cycle.
*
* See
* [GtkContainer’s geometry management section][container-geometry-management]
* to learn more about how height-for-width allocations are performed
* by container widgets.
*
* If a widget does move content around to intelligently use up the
* allocated size then it must support the request in both
* #GtkSizeRequestModes even if the widget in question only
* trades sizes in a single orientation.
*
* For instance, a #GtkLabel that does height-for-width word wrapping
* will not expect to have #GtkWidgetClass.get_preferred_height() called
* because that call is specific to a width-for-height request. In this
* case the label must return the height required for its own minimum
* possible width. By following this rule any widget that handles
* height-for-width or width-for-height requests will always be allocated
* at least enough space to fit its own content.
*
* Here are some examples of how a %GTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH widget
* generally deals with width-for-height requests, for #GtkWidgetClass.get_preferred_height()
* it will do:
*
* |[<!-- language="C" -->
* static void
* foo_widget_get_preferred_height (GtkWidget *widget,
* gint *min_height,
* gint *nat_height)
* {
* if (i_am_in_height_for_width_mode)
* {
* gint min_width, nat_width;
*
* GTK_WIDGET_GET_CLASS (widget)->get_preferred_width (widget,
* &min_width,
* &nat_width);
* GTK_WIDGET_GET_CLASS (widget)->get_preferred_height_for_width
* (widget,
* min_width,
* min_height,
* nat_height);
* }
* else
* {
* ... some widgets do both. For instance, if a GtkLabel is
* rotated to 90 degrees it will return the minimum and
* natural height for the rotated label here.
* }
* }
* ]|
*
* And in #GtkWidgetClass.get_preferred_width_for_height() it will simply return
* the minimum and natural width:
* |[<!-- language="C" -->
* static void
* foo_widget_get_preferred_width_for_height (GtkWidget *widget,
* gint for_height,
* gint *min_width,
* gint *nat_width)
* {
* if (i_am_in_height_for_width_mode)
* {
* GTK_WIDGET_GET_CLASS (widget)->get_preferred_width (widget,
* min_width,
* nat_width);
* }
* else
* {
* ... again if a widget is sometimes operating in
* width-for-height mode (like a rotated GtkLabel) it can go
* ahead and do its real width for height calculation here.
* }
* }
* ]|
*
* Often a widget needs to get its own request during size request or
* allocation. For example, when computing height it may need to also
* compute width. Or when deciding how to use an allocation, the widget
* may need to know its natural size. In these cases, the widget should
* be careful to call its virtual methods directly, like this:
*
* |[<!-- language="C" -->
* GTK_WIDGET_GET_CLASS(widget)->get_preferred_width (widget,
* &min,
* &natural);
* ]|
*
* It will not work to use the wrapper functions, such as
* gtk_widget_get_preferred_width() inside your own size request
* implementation. These return a request adjusted by #GtkSizeGroup
* and by the #GtkWidgetClass.adjust_size_request() virtual method. If a
* widget used the wrappers inside its virtual method implementations,
* then the adjustments (such as widget margins) would be applied
* twice. GTK+ therefore does not allow this and will warn if you try
* to do it.
*
* Of course if you are getting the size request for
* another widget, such as a child of a
* container, you must use the wrapper APIs.
* Otherwise, you would not properly consider widget margins,
* #GtkSizeGroup, and so forth.
*
* Since 3.10 GTK+ also supports baseline vertical alignment of widgets. This
* means that widgets are positioned such that the typographical baseline of
* widgets in the same row are aligned. This happens if a widget supports baselines,
* has a vertical alignment of %GTK_ALIGN_BASELINE, and is inside a container
* that supports baselines and has a natural “row” that it aligns to the baseline,
* or a baseline assigned to it by the grandparent.
*
* Baseline alignment support for a widget is done by the #GtkWidgetClass.get_preferred_height_and_baseline_for_width()
* virtual function. It allows you to report a baseline in combination with the
* minimum and natural height. If there is no baseline you can return -1 to indicate
* this. The default implementation of this virtual function calls into the
* #GtkWidgetClass.get_preferred_height() and #GtkWidgetClass.get_preferred_height_for_width(),
* so if baselines are not supported it doesn’t need to be implemented.
*
* If a widget ends up baseline aligned it will be allocated all the space in the parent
* as if it was %GTK_ALIGN_FILL, but the selected baseline can be found via gtk_widget_get_allocated_baseline().
* If this has a value other than -1 you need to align the widget such that the baseline
* appears at the position.
*
* # Style Properties
*
* #GtkWidget introduces “style
* properties” - these are basically object properties that are stored
* not on the object, but in the style object associated to the widget. Style
* properties are set in [resource files][gtk3-Resource-Files].
* This mechanism is used for configuring such things as the location of the
* scrollbar arrows through the theme, giving theme authors more control over the
* look of applications without the need to write a theme engine in C.
*
* Use gtk_widget_class_install_style_property() to install style properties for
* a widget class, gtk_widget_class_find_style_property() or
* gtk_widget_class_list_style_properties() to get information about existing
* style properties and gtk_widget_style_get_property(), gtk_widget_style_get() or
* gtk_widget_style_get_valist() to obtain the value of a style property.
*
* # GtkWidget as GtkBuildable
*
* The GtkWidget implementation of the GtkBuildable interface supports a
* custom <accelerator> element, which has attributes named ”key”, ”modifiers”
* and ”signal” and allows to specify accelerators.
*
* An example of a UI definition fragment specifying an accelerator:
* |[
* <object class="GtkButton">
* <accelerator key="q" modifiers="GDK_CONTROL_MASK" signal="clicked"/>
* </object>
* ]|
*
* In addition to accelerators, GtkWidget also support a custom <accessible>
* element, which supports actions and relations. Properties on the accessible
* implementation of an object can be set by accessing the internal child
* “accessible” of a #GtkWidget.
*
* An example of a UI definition fragment specifying an accessible:
* |[
* <object class="GtkLabel" id="label1"/>
* <property name="label">I am a Label for a Button</property>
* </object>
* <object class="GtkButton" id="button1">
* <accessibility>
* <action action_name="click" translatable="yes">Click the button.</action>
* <relation target="label1" type="labelled-by"/>
* </accessibility>
* <child internal-child="accessible">
* <object class="AtkObject" id="a11y-button1">
* <property name="accessible-name">Clickable Button</property>
* </object>
* </child>
* </object>
* ]|
*
* Finally, GtkWidget allows style information such as style classes to
* be associated with widgets, using the custom <style> element:
* |[
* <object class="GtkButton" id="button1">
* <style>
* <class name="my-special-button-class"/>
* <class name="dark-button"/>
* </style>
* </object>
* ]|
*
* # Building composite widgets from template XML ## {#composite-templates}
*
* GtkWidget exposes some facilities to automate the procedure
* of creating composite widgets using #GtkBuilder interface description
* language.
*
* To create composite widgets with #GtkBuilder XML, one must associate
* the interface description with the widget class at class initialization
* time using gtk_widget_class_set_template().
*
* The interface description semantics expected in composite template descriptions
* is slightly different from regular #GtkBuilder XML.
*
* Unlike regular interface descriptions, gtk_widget_class_set_template() will
* expect a <template> tag as a direct child of the toplevel <interface>
* tag. The <template> tag must specify the “class” attribute which must be
* the type name of the widget. Optionally, the “parent” attribute may be
* specified to specify the direct parent type of the widget type, this is
* ignored by the GtkBuilder but required for Glade to introspect what kind
* of properties and internal children exist for a given type when the actual
* type does not exist.
*
* The XML which is contained inside the <template> tag behaves as if it were
* added to the <object> tag defining @widget itself. You may set properties
* on @widget by inserting <property> tags into the <template> tag, and also
* add <child> tags to add children and extend @widget in the normal way you
* would with <object> tags.
*
* Additionally, <object> tags can also be added before and after the initial
* <template> tag in the normal way, allowing one to define auxiliary objects
* which might be referenced by other widgets declared as children of the
* <template> tag.
*
* An example of a GtkBuilder Template Definition:
* |[
* <interface>
* <template class="FooWidget" parent="GtkBox">
* <property name="orientation">GTK_ORIENTATION_HORIZONTAL</property>
* <property name="spacing">4</property>
* <child>
* <object class="GtkButton" id="hello_button">
* <property name="label">Hello World</property>
* <signal name="clicked" handler="hello_button_clicked" object="FooWidget" swapped="yes"/>
* </object>
* </child>
* <child>
* <object class="GtkButton" id="goodbye_button">
* <property name="label">Goodbye World</property>
* </object>
* </child>
* </template>
* </interface>
* ]|
*
* Typically, you'll place the template fragment into a file that is
* bundled with your project, using #GResource. In order to load the
* template, you need to call gtk_widget_class_set_template_from_resource()
* from the class initialization of your #GtkWidget type:
*
* |[<!-- language="C" -->
* static void
* foo_widget_class_init (FooWidgetClass *klass)
* {
* // ...
*
* gtk_widget_class_set_template_from_resource (GTK_WIDGET_CLASS (klass),
* "/com/example/ui/foowidget.ui");
* }
* ]|
*
* You will also need to call gtk_widget_init_template() from the instance
* initialization function:
*
* |[<!-- language="C" -->
* static void
* foo_widget_init (FooWidget *self)
* {
* // ...
* gtk_widget_init_template (GTK_WIDGET (self));
* }
* ]|
*
* You can access widgets defined in the template using the
* gtk_widget_get_template_child() function, but you will typically declare
* a pointer in the instance private data structure of your type using the same
* name as the widget in the template definition, and call
* gtk_widget_class_bind_template_child_private() with that name, e.g.
*
* |[<!-- language="C" -->
* typedef struct {
* GtkWidget *hello_button;
* GtkWidget *goodbye_button;
* } FooWidgetPrivate;
*
* G_DEFINE_TYPE_WITH_PRIVATE (FooWidget, foo_widget, GTK_TYPE_BOX)
*
* static void
* foo_widget_class_init (FooWidgetClass *klass)
* {
* // ...
* gtk_widget_class_set_template_from_resource (GTK_WIDGET_CLASS (klass),
* "/com/example/ui/foowidget.ui");
* gtk_widget_class_bind_template_child_private (GTK_WIDGET_CLASS (klass),
* FooWidget, hello_button);
* gtk_widget_class_bind_template_child_private (GTK_WIDGET_CLASS (klass),
* FooWidget, goodbye_button);
* }
*
* static void
* foo_widget_init (FooWidget *widget)
* {
*
* }
* ]|
*
* You can also use gtk_widget_class_bind_template_callback() to connect a signal
* callback defined in the template with a function visible in the scope of the
* class, e.g.
*
* |[<!-- language="C" -->
* // the signal handler has the instance and user data swapped
* // because of the swapped="yes" attribute in the template XML
* static void
* hello_button_clicked (FooWidget *self,
* GtkButton *button)
* {
* g_print ("Hello, world!\n");
* }
*
* static void
* foo_widget_class_init (FooWidgetClass *klass)
* {
* // ...
* gtk_widget_class_set_template_from_resource (GTK_WIDGET_CLASS (klass),
* "/com/example/ui/foowidget.ui");
* gtk_widget_class_bind_template_callback (GTK_WIDGET_CLASS (klass), hello_button_clicked);
* }
* ]|
