Control Bar — How to migrate Control Bars
ControlBar widgets are deprecated since Hildon 2.2 and a GtkScale should be used to accomplish the same functionality.
To make a GtkScale have the same functionality as a control bar you'll need to change some properties of the widget's Adjustment so it has a range equal to the control bar's as well as the step increment.
The following example shows a control bar with the range of 0 to 4.
Example 30. A Typical Control Bar
HildonControlbar *bar = HILDON_CONTROLBAR (hildon_controlbar_new ()); hildon_controlbar_set_range (bar, 1, 4); hildon_controlbar_set_value (bar, 2);
To accomplish the same functionality as the previous control bar example, one could use something like in the following example.
Example 31. A Replacement for the Control Bar
GtkHScale *scale = GTK_HSCALE (hildon_gtk_hscale_new ()); GtkAdjustment *adjustment = GTK_ADJUSTMENT ( gtk_range_get_adjustment (GTK_RANGE (scale))); g_object_set (adjustment, "step-increment", 1, "lower", 0, NULL); g_object_set (adjustment, "upper", 4, NULL); g_object_set (adjustment, "value", 2, NULL);
