columns - list of IGridColumns.

Method Details

getTree

public org.apache.wicket.extensions.markup.html.tree.AbstractTree getTree()

Returns the inner tree of the TreeGrid.

Returns:

inner tree

getTreeState

public org.apache.wicket.extensions.markup.html.tree.ITreeState getTreeState()

Returns the tree state

Returns:

tree state

update

public final void update()

During Ajax request updates the changed parts of tree.

Specified by:

update in class AbstractGrid<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>

onJunctionLinkClicked

protected void onJunctionLinkClicked(AjaxRequestTarget target,
 Object node)

Callback function called after user clicked on an junction link. The node has already been expanded/collapsed (depending on previous status).

Parameters:

target - Request target - may be null on non-ajax call

node - Node for which this callback is relevant

getSelectedItems

public Collection<IModel<I>> getSelectedItems()

Returns the collection of models of all currently selected items.

Specified by:

getSelectedItems in class AbstractGrid<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>

Returns:

collection of models of currently selected items

isAllowSelectMultiple

public boolean isAllowSelectMultiple()

Returns whether user will be able to select more than one item at a time.

Specified by:

isAllowSelectMultiple in class AbstractGrid<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>

Returns:

true if multiple items can be selected at a time, false otherwise.

setAllowSelectMultiple

public void setAllowSelectMultiple(boolean value)

Sets whether user will be able to select more than one item.

Specified by:

setAllowSelectMultiple in class AbstractGrid<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>

Parameters:

value - true if the user will be able to select more than one item at a time, false otherwise (single selection mode).

isItemSelected

public boolean isItemSelected(IModel<I> itemModel)

Queries whether the item specified by itemModel is currently selected.

Specified by:

isItemSelected in class AbstractGrid<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>

Parameters:

itemModel - item model

Returns:

true if the item is selected, false otherwise

resetSelectedItems

public void resetSelectedItems()

Deselects all items. This method marks all items (not just visible items) as no selected.

Specified by:

resetSelectedItems in class AbstractGrid<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>

selectAllVisibleItems

public void selectAllVisibleItems()

Marks all currently displayed items as selected. For DataGrid this selects all items on current page, for TreeGrid this selects all currently visible nodes.

Specified by:

selectAllVisibleItems in class AbstractGrid<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>

findRowComponent

protected WebMarkupContainer findRowComponent(IModel<I> rowModel)

Description copied from class: AbstractGrid

Returns the row component for specified item.

Specified by:

findRowComponent in class AbstractGrid<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>

Returns:

markItemDirty

public void markItemDirty(IModel<I> model)

Description copied from class: AbstractGrid

Marks the item from the given model as dirty. Dirty items are updated during Ajax requests when AbstractGrid.update() method is called.

Specified by:

markItemDirty in class AbstractGrid<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>

Parameters:

model - model used to access the item

selectItem

public void selectItem(IModel<I> itemModel,
 boolean selected)

Alters the selection state of item specified by the item model.

Specified by:

selectItem in class AbstractGrid<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>

Sets whether children of selected node should automatically be treated as selected nodes (default true). Such children can not be deselected individually. Also ITreeState.isNodeSelected(Object) returns true if any of node parent is selected. On the contrary, ITreeState.getSelectedNodes() only returns "top level" selected nodes.

Parameters:
