Sets our main struct and passes it to the parent class.
Creates a new #GtkCellRendererPixbuf. Adjust rendering parameters using object properties. Object properties can be set globally (with g_object_set()). Also, with #GtkTreeViewColumn, you can bind a property to a value in a #GtkTreeModel. For example, you can bind the “pixbuf” property on the cell renderer to a pixbuf value in the model, thus rendering a different image in each row of the #GtkTreeView.

Passes an activate event to the cell renderer for possible processing. Some cell renderers may use events; for example, #GtkCellRendererToggle toggles when it gets a mouse click.
Gets the aligned area used by @cell inside @cell_area. Used for finding the appropriate edit and focus rectangle.
Fills in @xalign and @yalign with the appropriate values of @cell.
Fills in @width and @height with the appropriate size of @cell.
Checks whether the given #GtkCellRenderer is expanded.
Checks whether the given #GtkCellRenderer is an expander.
Fills in @xpad and @ypad with the appropriate values of @cell.
Retrieves a renderer’s natural size when rendered to @widget.
Retrieves a cell renderers’s minimum and natural height if it were rendered to @widget with the specified @width.
Retrieves the minimum and natural size of a cell taking into account the widget’s preference for height-for-width management.
Retrieves a renderer’s natural size when rendered to @widget.
Retrieves a cell renderers’s minimum and natural width if it were rendered to @widget with the specified @height.
Gets whether the cell renderer prefers a height-for-width layout or a width-for-height layout.
Returns the cell renderer’s sensitivity.
Translates the cell renderer state to #GtkStateFlags, based on the cell renderer and widget sensitivity, and the given #GtkCellRendererState.
Returns the cell renderer’s visibility.
Checks whether the cell renderer can do something when activated.
Sets the renderer’s alignment within its available space.
Sets the renderer size to be explicit, independent of the properties set.
Sets whether the given #GtkCellRenderer is expanded.
Sets whether the given #GtkCellRenderer is an expander.
Sets the renderer’s padding.
Sets the cell renderer’s sensitivity.
Sets the cell renderer’s visibility.
Invokes the virtual render function of the #GtkCellRenderer. The three passed-in rectangles are areas in @cr. Most renderers will draw within @cell_area; the xalign, yalign, xpad, and ypad fields of the #GtkCellRenderer should be honored with respect to @cell_area. @background_area includes the blank space around the cell, and also the area containing the tree expander; so the @background_area rectangles for all cells tile to cover the entire @window.
Starts editing the contents of this @cell, through a new #GtkCellEditable widget created by the #GtkCellRendererClass.start_editing virtual function.
Informs the cell renderer that the editing is stopped. If @canceled is %TRUE, the cell renderer will emit the #GtkCellRenderer::editing-canceled signal.
This signal gets emitted when the user cancels the process of editing a cell. For example, an editable cell renderer could be written to cancel editing when the user presses Escape.
This signal gets emitted when a cell starts to be edited. The intended use of this signal is to do special setup on @editable, e.g. adding a #GtkEntryCompletion or setting up additional columns in a #GtkComboBox.
Renders a pixbuf in a cell
A #GtkCellRendererPixbuf can be used to render an image in a cell. It allows to render either a given #GdkPixbuf (set via the #GtkCellRendererPixbuf:pixbuf property) or a named icon (set via the #GtkCellRendererPixbuf:icon-name property).
To support the tree view, #GtkCellRendererPixbuf also supports rendering two alternative pixbufs, when the #GtkCellRenderer:is-expander property is %TRUE. If the #GtkCellRenderer:is-expanded property is %TRUE and the #GtkCellRendererPixbuf:pixbuf-expander-open property is set to a pixbuf, it renders that pixbuf, if the #GtkCellRenderer:is-expanded property is %FALSE and the #GtkCellRendererPixbuf:pixbuf-expander-closed property is set to a pixbuf, it renders that one.
