Segment Control

Widget description

Segment control widget is a horizontal control made of multiple segment items, each segment item functioning similar to discrete two state button. A segment control groups the items together and provides compact single button with multiple equal size segments.

Segment item size is determined by base widget size and the number of items added. Only one segment item can be at selected state. A segment item can display combination of Text and any Evas_Object like Images or other widget.

Layout content parts

• icon - An icon in a segment control item

Layout text parts

• default - Title label in a segment control item

class efl.elementary.SegmentControl(Object parent, *args, **kwargs)

Bases: efl.elementary.__init__.LayoutClass

Parameters:

• parent (efl.evas.Object) – The parent object
• **kwargs – All the remaining keyword arguments are interpreted as properties of the instance

callback_changed_add(func, *args, **kwargs)

When the user clicks on a segment item which is not previously selected and get selected. The event_info parameter is the segment item.

callback_changed_del(func)

item_add(icon=None, label=None)

Append a new item to the segment control object.

A new item will be created and appended to the segment control, i.e., will be set as last item.

If it should be inserted at another position, item_insert_at() should be used instead.

Items created with this function can be deleted with function efl.elementary.object_item.ObjectItem.delete() or item_del_at().

Simple example:

sc = SegmentControl(win)
ic = Icon(win, file="path/to/image", resizable=(True, True))
sc.item_add(ic, "label")
sc.show()

Note

label set to None is different from empty string “”. If an item only has icon, it will be displayed bigger and centered. If it has icon and label, even that an empty string, icon will be smaller and positioned at left.

Parameters:
