Hierarchy

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.layout.container.AbstractContainer.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). By default, +AnchorLayout will calculate anchor measurements based on the size of the container itself. However, the +container using the AnchorLayout can supply an anchoring-specific config property of anchorSize. +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.

+ +

Ext.layout.container.Anchor container layout

+ +

For example:

+ +
Ext.create('Ext.Panel', {
+    width: 500,
+    height: 400,
+    title: "AnchorLayout Panel",
+    layout: 'anchor',
+    renderTo: Ext.getBody(),
+    items: [{
+        xtype: 'panel',
+        title: '75% Width and 20% Height',
+        anchor: '75% 20%'
+    },{
+        xtype: 'panel',
+        title: 'Offset -300 Width & -200 Height',
+        anchor: '-300 -200'     
+    },{
+        xtype: 'panel',
+        title: 'Mixed Offset and Percent',
+        anchor: '-250 20%'
+    }]
+});

This configuation option is to be applied to child items of a container managed by +this layout (ie. configured with layout:'anchor').

+ + +
+ + + + +

This value is what tells the layout how an item should be anchored to the container. items +added to an AnchorLayout accept 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%'). +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. For example: +
    // two values specified
    +anchor: '100% 50%' // render item complete width of the container and
    +                   // 1/2 height of the container
    +// one value specified
    +anchor: '100%'     // the width value; the height will default to auto
    +
  • + +
  • Offsets : Any positive or negative integer value.
    +This is a raw adjustment where the first anchor is the offset from the right edge of the container, +and the second is the offset from the bottom edge. For example: +
    // two values specified
    +anchor: '-50 -100' // render item the complete width of the container
    +                   // minus 50 pixels and
    +                   // the complete height minus 100 pixels.
    +// one value specified
    +anchor: '-50'      // anchor value is assumed to be the right offset value
    +                   // 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.
  • + +
  • Mixed :
    +Anchor values can also be mixed as needed. For example, to render the width offset from the container +right edge by 50 pixels and 75% of the container's height use: +
    anchor: '-50 75%'
