The "orientation" property controls the direction and growth direction
of the progress bar (left-to-right, right-to-left, top-to-bottom or bottom-to-top).
Default value: gtk.PROGRESS_LEFT_TO_RIGHT. Available in GTK+ 2.12 and above.
Setting this to a non-negative value causes the cell renderer to enter
"activity mode", where a block bounces back and forth to indicate that some progress
is made, without specifying exactly how much. Each increment of the property causes
the block to move by a little bit. To indicate that the activity has not started yet,
set the property to zero. To indicate completion, set the property to G_MAXINT.
Allowed values: >= -1. Default value: -1. Available in GTK+ 2.12 and above.
The text in the label that will be drawn over the progress bar.
Setting this property to None causes the default label to
be displayed. Setting this property to an empty string causes no label to be
displayed. Default value: None. Available in GTK+ 2.6 and
The "text-xalign" property controls the horizontal alignment of the text
in the progress bar. Valid values range from 0 (left) to 1 (right). Reserved for
RTL layouts. Allowed values: [0,1]. Default value: 0.5. Available in GTK+ 2.12 and above.
The "text-yalign" property controls the vertical alignment of the text in
the progress bar. Valid values range from 0 (top) to 1 (bottom).
Allowed values: [0,1]. Default value: 0.5. Available in GTK+ 2.12 and above.
The percentage that the progress bar is "filled in".
Available in GTK+ 2.6 and above.
This constructor is available in PyGTK 2.6 and above.
Creates a new gtk.CellRendererProgress.
Rendering parameters are adjusted using the object properties. The object
properties can be set globally (with set_property()).
Also, with gtk.TreeViewColumn,
you can bind a property to a value in a gtk.TreeModel.
For example, you can bind the "text" property on the cell renderer to a
string value in the model, thus rendering a different string in each row of
