Class Ext.layout.AnchorLayout
-
-
- *
-
This is a layout that enables anchoring of contained elements relative to the container's dimensions. If
-the container is resized, all anchored items are automatically rerendered according to their anchor rules.
-This class is intended to be extended or created via the layout:'anchor' Ext.Container.layout config,
-and should generally not need to be created directly via the new keyword.
-
AnchorLayout does not have any direct config options (other than inherited ones). However, the container
-using the AnchorLayout can supply an anchoring-specific config property of anchorSize. By default,
-AnchorLayout will calculate anchor measurements based on the size of the container itself. However, if
-anchorSize is specifed, the layout will use it as a virtual container for the purposes of calculating anchor
-measurements based on it instead, allowing the container to be sized independently of the anchoring logic if necessary.
-
The items added to an AnchorLayout can also supply an anchoring-specific config property of anchor which
-is a string containing two values: the horizontal anchor value and the vertical anchor value (for example, '100% 50%').
-This value is what tells the layout how the item should be anchored to the container. The following types of
-anchor values are supported:
-
-- Percentage: Any value between 1 and 100, expressed as a percentage. The first anchor is the percentage
-width that the item should take up within the container, and the second is the percentage height. Example: '100% 50%'
-would render an item the complete width of the container and 1/2 its height. If only one anchor value is supplied
-it is assumed to be the width value and the height will default to auto.
-- Offsets: Any positive or negative integer value. The first anchor is the offset from the right edge of
-the container, and the second is the offset from the bottom edge. Example: '-50 -100' would render an item the
-complete width of the container minus 50 pixels and the complete height minus 100 pixels. If only one anchor value
-is supplied it is assumed to be the right offset value and the bottom offset will default to 0.
-- Sides: Valid values are 'right' (or 'r') and 'bottom' (or 'b'). Either the container must have a fixed
-size or an anchorSize config value defined at render time in order for these to have any effect.
-
-
Anchor values can also be mixed as needed. For example, '-50 75%' would render the width offset from the
-container right edge by 50 pixels and 75% of the container's height.
