description

a gtkprogress is the abstract base class used to derive a gtkprogressbar which provides a visual representation of the progress of a long running operation.

warning

gtk_progress_set_activity_mode is deprecated and should not be used in newly-written code.

a gtkprogress can be in one of two different modes: percentage mode (the default) and activity mode. in activity mode, the progress is simply indicated as activity rather than as a percentage complete.

property details

the "activity-mode" property

  "activity-mode"        gboolean              : read / write

if true the gtkprogress is in activity mode, meaning that it signals something is happening, but not how much of the activity is finished. this is used when you're doing something that you don't know how long it will take.

default value: false

the "show-text" property

  "show-text"            gboolean              : read / write

whether the progress is shown as text.

default value: false

the "text-xalign" property

  "text-xalign"          gfloat                : read / write

a number between 0.0 and 1.0 specifying the horizontal alignment of the text in the progress widget.

allowed values: [0,1]

default value: 0.5

the "text-yalign" property

  "text-yalign"          gfloat                : read / write

a number between 0.0 and 1.0 specifying the vertical alignment of the text in the progress widget.

allowed values: [0,1]

default value: 0.5
