Enclosing interface:

WinUser

public static class WinUser.WNDCLASSEX
extends Structure

Contains window class information. It is used with the RegisterClassEx and GetClassInfoEx functions. The WNDCLASSEX structure is similar to the WNDCLASS structure. There are two differences. WNDCLASSEX includes the cbSize member, which specifies the size of the structure, and the hIconSm member, which contains a handle to a small icon associated with the window class.

Method Detail

getFieldOrder

protected List<String> getFieldOrder()

Description copied from class: Structure

Return this Structure's field names in their proper order. For example,

 protected List getFieldOrder() {
     return Arrays.asList(new String[] { ... });
 }
 

IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.

 protected List getFieldOrder() {
     List fields = new ArrayList(super.getFieldOrder());
     fields.addAll(Arrays.asList(new String[] { ... }));
     return fields;
 }
 

Field order must be explicitly indicated, since the field order as returned by Class.getFields() is not guaranteed to be predictable.

Overrides:

getFieldOrder in class Structure

Returns:

ordered list of field names
