pub struct CellRendererProgress(_);
Expand description
Renders numbers as progress bars
CellRendererProgress
renders a numeric value as a progress par in a cell.
Additionally, it can display a text on top of the progress bar.

Implementations
Creates a new builder-pattern struct instance to construct CellRendererProgress
objects.
This method returns an instance of CellRendererProgressBuilder
which can be used to create CellRendererProgress
objects.
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
.

The “text” property determines the label which 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.

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.

The “text-yalign” property controls the vertical alignment of the text in the progress bar. Valid values range from 0 (top) to 1 (bottom).
The “text-yalign” property controls the vertical alignment of the text in the progress bar. Valid values range from 0 (top) to 1 (bottom).
The “value” property determines the percentage to which the progress bar will be “filled in”.
