View Full Version : LayoutData help

21 Jul 2009, 11:27 AM
Is there a documentaion that explains the LayoutData options and its effects on the widget being added.
For example, what exactly does FormData("-20") do? (I figured it reduces field size but not sure)

Sadly the documentation is sparse (although advertised as "fullly documented source code", this is not quite true; doc on every method - yes, helpful doc on every method - not really).

My two tips are: Check the javadoc and then if required check the source code. It's trivial to add the GXT2.0.zip as a source attachement to eclipse and the code is readable.

From the javadoc:
- FormData(java.lang.String anchorSpec) takes an anchorSpec
- AnchorSpec is used by the AnchorLayout (of which FormLayout is a sub-class)
- AnchorLayout java doc specifies the anchorSpec string as:

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...See: http://extjs.com/deploy/gxtdocs/com/extjs/gxt/ui/client/widget/layout/AnchorLayout.html
