A scroller holds (and clips) a single object and "scrolls it around". This means that it allows the user to use a scroll bar (or a finger) to drag the viewable region around, moving through a much larger object that is contained in the scroller. The scroller will always have a small minimum size by default as it won't be limited by the contents of the scroller.
This widget inherits from the Layout one, so that all the functions acting on it also work for scroller objects.
This widget emits the following signals, besides the ones sent from
"edge,left"
- the left edge of the content has been reached"edge,right"
- the right edge of the content has been reached"edge,top"
- the top edge of the content has been reached"edge,bottom"
- the bottom edge of the content has been reached"scroll"
- the content has been scrolled (moved)"scroll,left"
- the content has been scrolled (moved) leftwards"scroll,right"
- the content has been scrolled (moved) rightwards"scroll,up"
- the content has been scrolled (moved) upwards"scroll,down"
- the content has been scrolled (moved) downwards"scroll,anim,start"
- scrolling animation has started"scroll,anim,stop"
- scrolling animation has stopped"scroll,drag,start"
- dragging the contents around has started"scroll,drag,stop"
- dragging the contents around has stopped"vbar,drag"
- the vertical scroll bar has been dragged"vbar,press"
- the vertical scroll bar has been pressed"vbar,unpress"
- the vertical scroll bar has been unpressed"hbar,drag"
- the horizontal scroll bar has been dragged"hbar,press"
- the horizontal scroll bar has been pressed"hbar,unpress"
- the horizontal scroll bar has been unpressed"scroll,page,changed"
- the visible page has changed"focused"
- When the scroller has received focus. (since 1.8)"unfocused"
- When the scroller has lost focus. (since 1.8)
This widget implements the elm-scrollable-interface interface. Its (non-deprecated) API functions, except for elm_scroller_add(), which gives basic scroller objects, are meant to be a basis for all other scrollable widgets (i.e. widgets implementing elm-scrollable-interface). So, they will work both on pristine scroller widgets and on other "specialized" scrollable widgets.
- Note:
- The
"scroll,anim,*"
and"scroll,drag,*"
signals are only emitted by user intervention. - When Elementary is under its default profile and theme (meant for touch interfaces), scroll bars will not be draggable -- their function is merely to indicate how much has been scrolled.
- When Elementary is under its desktop/standard profile and theme, the thumb scroll (a.k.a. finger scroll) won't work.
Default content parts of the scroller widget that you can use are:
"default"
- A content of the scroller
In Scroller example you'll find an example on how to use most of this API.

Set blocking of scrolling (per axis) on a given scroller.
- Parameters:
-
obj The scroller object block The axis to block
This function will block scrolling movement (by input of a user) in a given direction. One can disable movements in the X axis, the Y axis or both. The default value is ELM_SCROLLER_MOVEMENT_NO_BLOCK, where movements are allowed in both directions.
What makes this function different from elm_object_scroll_freeze_push(), elm_object_scroll_hold_push() and elm_object_scroll_lock_x_set() (or elm_object_scroll_lock_y_set()) is that it doesn't propagate its effects to any parent or child widget of obj.

void elm_scroller_page_relative_set | ( | Evas_Object * | obj, |

double | v_pagerel | ||
) |
Set scroll page size relative to viewport size.
- Parameters:
-
obj The scroller object h_pagerel The horizontal page relative size v_pagerel The vertical page relative size
The scroller is capable of limiting scrolling by the user to "pages". That is to jump by and only show a "whole page" at a time as if the continuous area of the scroller content is split into page sized pieces. This sets the size of a page relative to the viewport of the scroller. 1.0 is "1 viewport" is size (horizontally or vertically). 0.0 turns it off in that axis. This is mutually exclusive with page size (see elm_scroller_page_size_set() for more information). Likewise 0.5 is "half a viewport". Sane usable values are normally between 0.0 and 1.0 including 1.0. If you only want 1 axis to be page "limited", use 0.0 for the other axis.
