Sets our main struct and passes it to the parent class.
Creates a new Tree view column
Creates a new #GtkTreeViewColumn.
Creates a new #GtkTreeViewColumn using @area to render its cells.
Obtains the horizontal position and size of a cell in a column. If the cell is not found in the column, @start_pos and @width are not changed and %FALSE is returned.
Obtains the width and height needed to render the column. This is used primarily by the #GtkTreeView.
Returns %TRUE if any of the cells packed into the @tree_column are visible. For this to be meaningful, you must first initialize the cells with gtk_tree_view_column_cell_set_cell_data()
Sets the cell renderer based on the @tree_model and @iter. That is, for every attribute mapping in @tree_column, it will get a value from the set column on the @iter, and use that value to set the attribute on the cell renderer. This is used primarily by the #GtkTreeView.
Emits the “clicked” signal on the column. This function will only work if @tree_column is clickable.
Sets the current keyboard focus to be at @cell, if the column contains 2 or more editable and activatable cells.
Returns the current x alignment of @tree_column. This value can range between 0.0 and 1.0.
Returns the button used in the treeview column header
Returns %TRUE if the user can click on the header for the column.
Returns %TRUE if the column expands to fill available space.
Gets the fixed width of the column. This may not be the actual displayed width of the column; for that, use gtk_tree_view_column_get_width().
Returns the maximum width in pixels of the @tree_column, or -1 if no maximum width is set.
Returns the minimum width in pixels of the @tree_column, or -1 if no minimum width is set.
Returns %TRUE if the @tree_column can be reordered by the user.
Returns %TRUE if the @tree_column can be resized by the end user.
Returns the current type of @tree_column.
Gets the logical @sort_column_id that the model sorts on when this column is selected for sorting. See gtk_tree_view_column_set_sort_column_id().
Gets the value set by gtk_tree_view_column_set_sort_indicator().
Gets the value set by gtk_tree_view_column_set_sort_order().
Returns the spacing of @tree_column.
the main Gtk struct as a void*
Returns the title of the widget.
Returns the GtkTreeView wherein tree_column has been inserted. If column is currently not inserted in any tree view, NULL is returned. Since 2.12
Get the main Gtk struct
Returns %TRUE if @tree_column is visible.
Returns the #GtkWidget in the button on the column header. If a custom widget has not been set then %NULL is returned.
Returns the current size of @tree_column in pixels.
Returns the current X offset of @tree_column in pixels.
Flags the column, and the cell renderers added to this column, to have their sizes renegotiated.
Sets the alignment of the title or custom widget inside the column header. The alignment determines its location inside the button -- 0.0 for left, 0.5 for center, 1.0 for right.
Sets the #GtkTreeCellDataFunc to use for the column. This function is used instead of the standard attributes mapping for setting the column value, and should set the value of @tree_column's cell renderer as appropriate. @func may be %NULL to remove an older one.
Sets the header to be active if @clickable is %TRUE. When the header is active, then it can take keyboard focus, and can be clicked.
Sets the column to take available extra space. This space is shared equally amongst all columns that have the expand set to %TRUE. If no column has this option set, then the last column gets all extra space. By default, every column is created with this %FALSE.
If @fixed_width is not -1, sets the fixed width of @tree_column; otherwise unsets it. The effective value of @fixed_width is clamped between the minimum and maximum width of the column; however, the value stored in the “fixed-width” property is not clamped. If the column sizing is #GTK_TREE_VIEW_COLUMN_GROW_ONLY or #GTK_TREE_VIEW_COLUMN_AUTOSIZE, setting a fixed width overrides the automatically calculated width. Note that @fixed_width is only a hint to GTK+; the width actually allocated to the column may be greater or less than requested.
Sets the maximum width of the @tree_column. If @max_width is -1, then the maximum width is unset. Note, the column can actually be wider than max width if it’s the last column in a view. In this case, the column expands to fill any extra space.
Sets the minimum width of the @tree_column. If @min_width is -1, then the minimum width is unset.
If @reorderable is %TRUE, then the column can be reordered by the end user dragging the header.
If @resizable is %TRUE, then the user can explicitly resize the column by grabbing the outer edge of the column button. If resizable is %TRUE and sizing mode of the column is #GTK_TREE_VIEW_COLUMN_AUTOSIZE, then the sizing mode is changed to #GTK_TREE_VIEW_COLUMN_GROW_ONLY.
Sets the growth behavior of @tree_column to @type.
Sets the logical @sort_column_id that this column sorts on when this column is selected for sorting. Doing so makes the column header clickable.
Call this function with a @setting of %TRUE to display an arrow in the header button indicating the column is sorted. Call gtk_tree_view_column_set_sort_order() to change the direction of the arrow.
Changes the appearance of the sort indicator.
Sets the spacing field of @tree_column, which is the number of pixels to place between cell renderers packed into it.
Sets the title of the @tree_column. If a custom widget has been set, then this value is ignored.
Sets the visibility of @tree_column.
Sets the widget in the header to be @widget. If widget is %NULL, then the header button is set with a #GtkLabel set to the title of @tree_column.

Gets a D Object from the objects table of associations.
The notify signal is emitted on an object when one of its properties has been changed. Note that getting this signal doesn't guarantee that the value of the property has actually changed, it may also be emitted when the setter for the property is called to reinstate the previous value.
Find the #GParamSpec with the given name for an interface. Generally, the interface vtable passed in as @g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().
Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.
Lists the properties of an interface.Generally, the interface vtable passed in as @g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().
Increases the reference count of the object by one and sets a callback to be called when all other references to the object are dropped, or when this is already the last reference to the object and another reference is established.
Adds a weak reference from weak_pointer to @object to indicate that the pointer located at @weak_pointer_location is only valid during the lifetime of @object. When the @object is finalized, @weak_pointer will be set to %NULL.
Creates a binding between @source_property on @source and @target_property on @target. Whenever the @source_property is changed the @target_property is updated using the same value. For instance:
Complete version of g_object_bind_property().
Creates a binding between @source_property on @source and @target_property on @target, allowing you to set the transformation functions to be used by the binding.
This is a variant of g_object_get_data() which returns a 'duplicate' of the value. @dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object.
This is a variant of g_object_get_qdata() which returns a 'duplicate' of the value. @dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object.
This function is intended for #GObject implementations to re-enforce a floating[floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink().
Increases the freeze count on @object. If the freeze count is non-zero, the emission of "notify" signals on @object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.
Gets a named field from the objects table of associations (see g_object_set_data()).
Gets a property of an object. @value must have been initialized to the expected type of the property (or a type to which the expected type can be transformed) using g_value_init().
This function gets back user data pointers stored via g_object_set_qdata().
Gets properties of an object.
Checks whether @object has a floating[floating-ref] reference.
Emits a "notify" signal for the property @property_name on @object.
Emits a "notify" signal for the property specified by @pspec on @object.
Increases the reference count of @object.
Increase the reference count of @object, and possibly remove the floating[floating-ref] reference, if @object has a floating reference.
Removes a reference added with g_object_add_toggle_ref(). The reference count of the object is decreased by one.
Removes a weak reference from @object that was previously added using g_object_add_weak_pointer(). The @weak_pointer_location has to match the one used with g_object_add_weak_pointer().
Compares the user data for the key @key on @object with @oldval, and if they are the same, replaces @oldval with @newval.
Compares the user data for the key @quark on @object with @oldval, and if they are the same, replaces @oldval with @newval.
Releases all references to other objects. This can be used to break reference cycles.
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
Like g_object_set_data() except it adds notification for when the association is destroyed, either by setting it to a different value or when the object is destroyed.
Sets a property on an object.
This sets an opaque, named pointer on an object. The name is specified through a #GQuark (retrived e.g. via g_quark_from_static_string()), and the pointer can be gotten back from the @object with g_object_get_qdata() until the @object is finalized. Setting a previously set user data pointer, overrides (frees) the old pointer set, using #NULL as pointer essentially removes the data stored.
This function works like g_object_set_qdata(), but in addition, a void (*destroy) (gpointer) function may be specified which is called with @data as argument when the @object is finalized, or the data is being overwritten by a call to g_object_set_qdata() with the same @quark.
Sets properties on an object.
Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
This function gets back user data pointers stored via g_object_set_qdata() and removes the @data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example: |[<!-- language="C" --> void object_add_to_user_list (GObject *object, const gchar *new_string) { // the quark, naming the object data GQuark quark_string_list = g_quark_from_static_string ("my-string-list"); // retrive the old string list GList *list = g_object_steal_qdata (object, quark_string_list);
Reverts the effect of a previous call to g_object_freeze_notify(). The freeze count is decreased on @object and when it reaches zero, queued "notify" signals are emitted.
Decreases the reference count of @object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).
This function essentially limits the life time of the @closure to the life time of the object. That is, when the object is finalized, the @closure is invalidated by calling g_closure_invalidate() on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, g_object_ref() and g_object_unref() are added as marshal guards to the @closure, to ensure that an extra reference count is held on @object during invocation of the @closure. Usually, this function will be called on closures that use this @object as closure data.
Adds a weak reference callback to an object. Weak references are used for notification when an object is finalized. They are called "weak references" because they allow you to safely hold a pointer to an object without calling g_object_ref() (g_object_ref() adds a strong reference, that is, forces the object to stay alive).
Removes a weak reference callback to an object.
Clears a reference to a #GObject.

Adds a child to @buildable. @type is an optional string describing how the child should be added.
Constructs a child of @buildable with the name @name.
This is similar to gtk_buildable_parser_finished() but is called once for each custom tag handled by the @buildable.
This is called at the end of each custom element handled by the buildable.
This is called for each unknown element under <child>.
Get the internal child called @childname of the @buildable object.
Gets the name of the @buildable object.
Called when the builder finishes the parsing of a [GtkBuilder UI definition][BUILDER-UI]. Note that this will be called once for each time gtk_builder_add_from_file() or gtk_builder_add_from_string() is called on a builder.
Sets the property name @name to @value on the @buildable object.
Sets the name of the @buildable object.

Adds an attribute mapping to the list in @cell_layout.
Unsets all the mappings on all renderers on @cell_layout and removes all renderers from @cell_layout.
Clears all existing attributes previously set with gtk_cell_layout_set_attributes().
Returns the underlying #GtkCellArea which might be @cell_layout if called on a #GtkCellArea or might be %NULL if no #GtkCellArea is used by @cell_layout.
Returns the cell renderers which have been added to @cell_layout.
Adds the @cell to the end of @cell_layout. If @expand is %FALSE, then the @cell is allocated no more space than it needs. Any unused space is divided evenly between cells for which @expand is %TRUE.
Packs the @cell into the beginning of @cell_layout. If @expand is %FALSE, then the @cell is allocated no more space than it needs. Any unused space is divided evenly between cells for which @expand is %TRUE.
Re-inserts @cell at @position.
Sets the #GtkCellLayoutDataFunc to use for @cell_layout.
The GtkTreeViewColumn object represents a visible column in a #GtkTreeView widget. It allows to set properties of the column header, and functions as a holding pen for the cell renderers which determine how the data in the column is displayed.
