===== Container Programming Guide =====
|
||
|
|
||
|
Elementary is about displaying its widgets in a nice layout, for this purpose
|
||
|
it provides a number of containers.

Most of the time, you want to display widgets on the screen in a specific
|
||
|
order. In Form Tutorial, for example, the user information is arranged
|
||
|
vertically. This basic container is called a box. There is no theme for a box
|
||
|
layout. It is just a linear method of arranging widgets horizontally or
|
||
|
vertically.

{{ :container_conformant_tree.png }}{{ :container_conformant.png }}
|
||
|
|
||
|
A conformant is a container widget that accounts for the space taken by the
|
||
|
indicator, virtual keyboard, and softkey windows. The content area of the
|
||
|
conformant is resized and positioned based on the space available. When the
|
||
|
virtual keyboard is displayed, the content area is not resized.

Gengrid widget is based on the same idea as the genlist. It aims at displaying
|
||
|
objects on a grid layout and rendering only the visible ones. As for the
|
||
|
genlist, callbacks are called at item creation or deletion.
|
||
|
|
||
|
This widget inherits from the layout widget and implements the scroller
|
||
|
interface. Thus scroller and layout functions can be used with this widget.
|
||
|
|
||
|
A gengrid may display its items using horizontal or vertical layout. In the
|
||
|
first layout, items are displayed in columns from top to bottom, starting a
|
||
|
new column when the space for the current column is filled. In the second one,
|
||
|
items are set in rows from left to right.

Genlist is a widget that displays a scrollable list of items. It allows a lot of entries while being fast and has a low memory footprint (only the visible items are allocated in the memory).

|
||
|
In a grid, objects are placed at specific positions along a fixed grid, where
|
||
|
the position of each object is given as a percentage of the full width and
|
||
|
height of the grid. By default, the size of the grid is 100 x 100 pixels.

++++Layout Container|
|
||
|
A layout is a container widget that takes a standard Edje design file and
|
||
|
wraps it very thinly in a widget. Layouts are the basis of a lot of graphics
|
||
|
widgets used in Elementary.
|
||
|
|
||
|
An Edje design file describes how the elements of the UI are positioned and
|
||
|
how they behave when interacted with. For more information about Edje, see the
|
||
|
Edje guide.

|

|
{{ :container_mapbuf_tree.png }}
|
||
|
|
||
|
A mapbuf widget is a container widget that uses an Evas map to hold a content
|
||
|
object. This widget is used to improve the moving and resizing performance of
|
||
|
complex widgets.
|
||
|
|
||
|
The content object is treated as a single image by the Evas map. If you have a
|
||
|
content object containing several child objects, frequently moving the mapbuf
|
||
|
widget will be faster than frequently moving the content object.
|
||
|
|
||
|
The mapbuf widget inherits all the functions of the container class.

|

|
{{ :container_naviframe_tree.png }}
|
||
|
|
||
|
A naviframe widget consists of a stack of views. New views are pushed on top
|
||
|
of previous ones, and only the top-most view on the stack is displayed. The
|
||
|
previous views are not deleted. A previous view is displayed when the view on
|
||
|
top of it is popped. Transitions can be animated on a push or a pop, depending
|
||
|
on the theme applied to the widget.

|

|
|

A panes widget adds a draggable bar between two sections of content. The
|
||
|
sections are resized when the bar is dragged.

{{ :container_scroller_tree.png }}{{ :container_scroller.png }}
|
||
|
|
||
|
A scroller holds (and clips) a single object and allows you to scroll across
|
||
|
it. This means that the user can use a scroll bar or their finger to drag the
|
||
|
viewable region across the object, moving through a much larger area than is
|
||
|
contained in the viewport. The scroller will always have a default minimum
|
||
|
size that is not limited by its contents.
|
||
|
|
||
|
The scroller widget inherits all the functions of the Layout Container.

A table is like a box but with 2 dimensions. You have the same kind of APIs as
|
||
|
with boxes. An item inside the table can span multiple columns and rows, and
|
||
|
even overlap with other items (and it can then be raised or lowered
|
||
|
accordingly to adjust stacking if there is overlap).
