: Object
Returns flags indicating cross-browser handling of scrollHeight/Width. ...

Returns flags indicating cross-browser handling of scrollHeight/Width. In particular,\nIE has issues with padding-bottom in a scrolling element (it does not include that\npadding in the scrollHeight). Also, margin-bottom on a child in a scrolling element\ncan be lost.

\n\n

All browsers seem to ignore margin-right on children and padding-right on the parent\nelement (the one with the overflow)

\n\n

This method returns a number with the follow bit positions set based on things not\naccounted for in scrollHeight and scrollWidth:

\n\n
    \n
  • 1: Scrolling element's padding-bottom is not included in scrollHeight.
    • \n
  • 2: Last child's margin-bottom is not included in scrollHeight.
    • \n
  • 4: Scrolling element's padding-right is not included in scrollWidth.
    • \n
  • 8: Child's margin-right is not included in scrollWidth.
    • \n
\n\n\n

To work around the margin-bottom issue, it is sufficient to create a 0px tall last\nchild that will \"hide\" the margin. This can also be handled by wrapping the children\nin an element, again \"hiding\" the margin. Wrapping the elements is about the only\nway to preserve their right margins. This is the strategy used by Column layout.

\n\n

To work around the padding-bottom problem, since it is comes from a style on the\nparent element, about the only simple fix is to create a last child with height\nequal to padding-bottom. To preserve the right padding, the sizing element needs to\nhave a width that includes the right padding.

\n

Parameters

Ext.layout.Layout
view source
( Ext.layout.ContextItem ownerContext )abstract
Called to perform the calculations for this layout. ...

Called to perform the calculations for this layout. This method will be called at\nleast once and may be called repeatedly if the done property is cleared\nbefore return to indicate that this layout is not yet done. The done property\nis always set to true before entering this method.

\n\n

This is a read phase and DOM writes should be strictly avoided in derived classes.\nInstead, DOM writes need to be written to Ext.layout.ContextItem objects to\n be flushed at the next opportunity.

\n

Parameters

Ext.layout.container.Container
view source
( Ext.layout.ContextItem ownerContext, Object containerSize, Number dimensions )
Handles overflow processing for a container. ...

Handles overflow processing for a container. This should be called once the layout\nhas determined contentWidth/Height. In addition to the ownerContext passed to the\ncalculate method, this method also needs the containerSize (the object\nreturned by getContainerSize).

\n

Parameters

  • ownerContext : Ext.layout.ContextItem
    \n
  • containerSize : Object
    \n
  • dimensions : Number

    A bit mask for the overflow managed dimensions. The 0-bit\nis for width and the 1-bit is for height. In other words, a value of 1 would be\nonly width, 2 would be only height and 3 would be both.

\n\n
\n

Parameters

  • args : Array/Arguments

    The arguments, either an array or the arguments object\nfrom the current method, for example: this.callOverridden(arguments)

    \n

Returns

  • Object

    Returns the result of calling the overridden method

    \n
Ext.Base
view source
( Array/Arguments args ) : Objectprotected
Call the \"parent\" method of the current method. ...

Call the \"parent\" method of the current method. That is the method previously\noverridden by derivation or by an override (see Ext.define).

\n\n
 Ext.define('My.Base', {\n     constructor: function (x) {\n         this.x = x;\n     },\n\n     statics: {\n         method: function (x) {\n             return x;\n         }\n     }\n });\n\n Ext.define('My.Derived', {\n     extend: 'My.Base',\n\n     constructor: function () {\n         this.callParent([21]);\n     }\n });\n\n var obj = new My.Derived();\n\n alert(obj.x);  // alerts 21\n
\n\n

This can be used with an override as follows:

\n\n
 Ext.define('My.DerivedOverride', {\n     override: 'My.Derived',\n\n     constructor: function (x) {\n         this.callParent([x*2]); // calls original My.Derived constructor\n     }\n });\n\n var obj = new My.Derived();\n\n alert(obj.x);  // now alerts 42\n
\n\n

This also works with static methods.

\n\n
 Ext.define('My.Derived2', {\n     extend: 'My.Base',\n\n     statics: {\n         method: function (x) {\n             return this.callParent([x*2]); // calls My.Base.method\n         }\n     }\n });\n\n alert(My.Base.method(10);     // alerts 10\n alert(My.Derived2.method(10); // alerts 20\n
\n\n

Lastly, it also works with overridden static methods.

\n\n
 Ext.define('My.Derived2Override', {\n     override: 'My.Derived2',\n\n     statics: {\n         method: function (x) {\n             return this.callParent([x*2]); // calls My.Derived2.method\n         }\n     }\n });\n\n alert(My.Derived2.method(10); // now alerts 40\n
\n

Parameters

  • args : Array/Arguments

    The arguments, either an array or the arguments object\nfrom the current method, for example: this.callParent(arguments)

    \n

Returns

  • Object

    Returns the result of calling the parent method

This method (if implemented) is called at the end of the cycle in which this layout\ncompletes (by not setting done to false in calculate). It is\npossible for the layout to complete and yet become invalid before the end of the cycle,\nin which case, this method will not be called. It is also possible for this method to\nbe called and then later the layout becomes invalidated. This will result in\ncalculate being called again, followed by another call to this method.

\n\n

This is a read phase and DOM writes should be strictly avoided in derived classes.\nInstead, DOM writes need to be written to Ext.layout.ContextItem objects to\nbe flushed at the next opportunity.

\n\n

This method need not be implemented by derived classes and, in fact, should only be\nimplemented when needed.

\n

Parameters

Ext.layout.Layout
view source
( Ext.layout.ContextItem ownerContext )
This method (if implemented) is called after all layouts have completed. ...

This method (if implemented) is called after all layouts have completed. In most\nways this is similar to completeLayout. This call can cause this (or any\nlayout) to be become invalid (see Ext.layout.Context.invalidate), but this\nis best avoided. This method is intended to be where final reads are made and so it\nis best to avoid invalidating layouts at this point whenever possible. Even so, this\nmethod can be used to perform final checks that may require all other layouts to be\ncomplete and then invalidate some results.

\n\n

This is a read phase and DOM writes should be strictly avoided in derived classes.\nInstead, DOM writes need to be written to Ext.layout.ContextItem objects to\nbe flushed at the next opportunity.

\n\n

This method need not be implemented by derived classes and, in fact, should only be\nimplemented when needed.

\n

Parameters

Ext.layout.Layout
view source
( Ext.layout.ContextItem ownerContext )
This method is called after all layouts are complete and their calculations flushed\nto the DOM. ...

This method is called after all layouts are complete and their calculations flushed\nto the DOM. No further layouts will be run and this method is only called once per\nlayout run. The base component layout caches lastComponentSize.

\n\n

This is a write phase and DOM reads should be avoided if possible when overridding\nthis method.

\n\n

This method need not be implemented by derived classes and, in fact, should only be\nimplemented when needed.

Parameters

Ext.Base

( Object members ) : Ext.Basedeprecatedstatic
Override members of this class. ...

Override members of this class. Overridden methods can be invoked via\ncallParent.

\n\n
Ext.define('My.Cat', {\n    constructor: function() {\n        alert(\"I'm a cat!\");\n    }\n});\n\nMy.Cat.override({\n    constructor: function() {\n        alert(\"I'm going to be a cat!\");\n\n        this.callParent(arguments);\n\n        alert(\"Meeeeoooowwww\");\n    }\n});\n\nvar kitty = new My.Cat(); // alerts \"I'm going to be a cat!\"\n                          // alerts \"I'm a cat!\"\n                          // alerts \"Meeeeoooowwww\"\n
\n\n

As of 4.1, direct use of this method is deprecated. Use Ext.define\ninstead:

\n\n
Ext.define('My.CatOverride', {\n    override: 'My.Cat',\n    constructor: function() {\n        alert(\"I'm going to be a cat!\");\n\n        this.callParent(arguments);\n\n        alert(\"Meeeeoooowwww\");\n    }\n});\n
\n\n

The above accomplishes the same result but can be managed by the Ext.Loader\nwhich can properly order the override and its target class and the build process\ncan determine whether the override is needed based on the required state of the\ntarget class (My.Cat).

\n
\n

This method has been deprecated since 4.1.0

\n

Use Ext.define instead
