Method Detail

getActivePage
public int getActivePage()(Code)
	Returns the active page (starting from 0). since: 2.4.1

getItemCount
public int getItemCount()(Code)
	Returns the number of child Treeitem including all descendants. The same as Treechildren.getItems .size(). Note: the performance is no good.

getItems
public Collection getItems()(Code)
	Returns a readonly list of all descending Treeitem (children's children and so on). Note: the performance of the size method of returned collection is no good.

getLinkedTreerow
public Treerow getLinkedTreerow()(Code)
	Returns the Treerow that is associated with this treechildren, or null if no such treerow. In other words, it is Treeitem.getTreerow of Treechildren.getParent . since: 2.4.1 See Also: Treerow.getLinkedTreechildren

getPageCount
public int getPageCount()(Code)
	Returns the number of pages (at least one). Note: there is at least one page even no item at all. since: 2.4.1

getPageSize

public int getPageSize()(Code)

Returns the page size which controls the number of visible child Treeitem , or -1 if no limitation.

If Treechildren.setPageSize is called with a non-zero value, this method return the non-zero value. If Treechildren.setPageSize is called with zero, this method returns Tree.getPageSize of Treechildren.getTree .

Default: the same as Treechildren.getTree 's Tree.getPageSize .
since:
   2.4.1
See Also:   Tree.getPageSize
See Also:   Treechildren.setPageSize

getPageSizeDirectly
int getPageSizeDirectly()(Code)

getTree
public Tree getTree()(Code)
	Returns the Tree instance containing this element.

getVisibleBegin
public int getVisibleBegin()(Code)
	Returns the index of the first visible child. Used only for component development, not for application developers. since: 2.4.1

getVisibleEnd
public int getVisibleEnd()(Code)
	Returns the index of the last visible child. Used only for component development, not for application developers. since: 2.4.1

insertBefore
public boolean insertBefore(Component child, Component insertBefore)(Code)

invalidate
public void invalidate()(Code)

isVisible
public boolean isVisible()(Code)
	Returns whether this is visible. Besides depends on Treechildren.setVisible , it also depends on whether all its ancestors is open.

newExtraCtrl
protected Object newExtraCtrl()(Code)

onChildRemoved
public void onChildRemoved(Component child)(Code)

setActivePage
public void setActivePage(int pg) throws WrongValueException(Code)
	Sets the active page (starting from 0). exception: WrongValueException - if no such page since: 2.4.1

setActivePageDirectly
void setActivePageDirectly(int pg)(Code)
	Called by Tree to set the active page directly.

setPageSize
public void setPageSize(int size) throws WrongValueException(Code)
	Sets the page size which controls the number of visible child Treeitem . Parameters: size - the page size. If zero, the page size will bethe same as Tree.getPageSize of Treechildren.getTree.In other words, zero means the default page size is used.If negative, all Treeitem are shown. since: 2.4.1

setParent
public void setParent(Component parent)(Code)

smartUpdate
public void smartUpdate(String name, String value)(Code)
