javax.swing.tree.VariableHeightLayoutCache — clojure-interop/javax.swing 1.0.5

NOTE: This will become more open in a future release.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

->variable-height-layout-cache clj

(->variable-height-layout-cache)

Constructor.

expanded? clj

(expanded? this path)

Returns true if the value identified by path is currently expanded.

path - javax.swing.tree.TreePath

returns: true if the value identified by path is currently expanded - boolean

get-bounds clj

(get-bounds this path place-in)

Returns the Rectangle enclosing the label portion into which the item identified by path will be drawn.

path - the path to be drawn - javax.swing.tree.TreePath place-in - the bounds of the enclosing rectangle - java.awt.Rectangle

returns: the bounds of the enclosing rectangle or null if the node could not be ascertained - java.awt.Rectangle

get-expanded-state? clj

(get-expanded-state? this path)

Returns true if the path is expanded, and visible.

path - the path being queried - javax.swing.tree.TreePath

returns: true if the path is expanded and visible, otherwise false - boolean

get-path-closest-to clj

(get-path-closest-to this x y)

Returns the path to the node that is closest to x,y. If there is nothing currently visible this will return null, otherwise it will always return a valid path. If you need to test if the returned object is exactly at x, y you should get the bounds for the returned path and test x, y against that.

x - the x-coordinate - int y - the y-coordinate - int

returns: the path to the node that is closest to x, y - javax.swing.tree.TreePath

get-path-for-row clj

(get-path-for-row this row)

Returns the path for row. If row is not visible, null is returned.

row - the location of interest - int

returns: the path for row, or null if row is not visible - javax.swing.tree.TreePath

get-preferred-height clj

(get-preferred-height this)

Returns the preferred height.

returns: the preferred height - int

get-preferred-width clj

(get-preferred-width this bounds)

Returns the preferred width and height for the region in visibleRegion.

bounds - the region being queried - java.awt.Rectangle

returns: the preferred width for the passed in region - int

get-row-count clj

(get-row-count this)

Returns the number of visible rows.

returns: the number of visible rows - int

get-row-for-path clj

(get-row-for-path this path)

Returns the row where the last item identified in path is visible. Will return -1 if any of the elements in path are not currently visible.

path - the TreePath of interest - javax.swing.tree.TreePath

returns: the row where the last item in path is visible - int

get-visible-child-count clj

(get-visible-child-count this path)

Returns the number of visible children for path.

path - the path being queried - javax.swing.tree.TreePath

returns: the number of visible children for path - int

get-visible-paths-from clj

(get-visible-paths-from this path)

Returns an Enumerator that increments over the visible paths starting at the passed in location. The ordering of the enumeration is based on how the paths are displayed.

path - the location in the TreePath to start - javax.swing.tree.TreePath

returns: an Enumerator that increments over the visible paths - java.util.Enumeration<javax.swing.tree.TreePath>

invalidate-path-bounds clj

(invalidate-path-bounds this path)

Instructs the LayoutCache that the bounds for path are invalid, and need to be updated.

path - the TreePath which is now invalid - javax.swing.tree.TreePath

invalidate-sizes clj

(invalidate-sizes this)

Informs the TreeState that it needs to recalculate all the sizes it is referencing.

set-expanded-state clj

(set-expanded-state this path is-expanded)

Marks the path path expanded state to isExpanded.

path - the TreePath of interest - javax.swing.tree.TreePath is-expanded - true if the path should be expanded, otherwise false - boolean

set-model clj

(set-model this new-model)

Sets the TreeModel that will provide the data.

new-model - the TreeModel that is to provide the data - javax.swing.tree.TreeModel

set-node-dimensions clj

(set-node-dimensions this nd)

Sets the renderer that is responsible for drawing nodes in the tree.

nd - the renderer - javax.swing.tree.AbstractLayoutCache$NodeDimensions

set-root-visible clj

(set-root-visible this root-visible)

Determines whether or not the root node from the TreeModel is visible.

root-visible - true if the root node of the tree is to be displayed - boolean

set-row-height clj

(set-row-height this row-height)

Sets the height of each cell. If the specified value is less than or equal to zero the current cell renderer is queried for each row's height.

row-height - the height of each cell, in pixels - int

tree-nodes-changed clj

(tree-nodes-changed this e)

Invoked after a node (or a set of siblings) has changed in some way. The node(s) have not changed locations in the tree or altered their children arrays, but other attributes have changed and may affect presentation. Example: the name of a file has changed, but it is in the same location in the file system.

e.path returns the path the parent of the changed node(s).

e.childIndices returns the index(es) of the changed node(s).

e - the TreeModelEvent of interest - javax.swing.event.TreeModelEvent

tree-nodes-inserted clj

(tree-nodes-inserted this e)

Invoked after nodes have been inserted into the tree.

e.path returns the parent of the new nodes. e.childIndices returns the indices of the new nodes in ascending order.

e - the TreeModelEvent of interest - javax.swing.event.TreeModelEvent

tree-nodes-removed clj

(tree-nodes-removed this e)

Invoked after nodes have been removed from the tree. Note that if a subtree is removed from the tree, this method may only be invoked once for the root of the removed subtree, not once for each individual set of siblings removed.

e.path returns the former parent of the deleted nodes.

e.childIndices returns the indices the nodes had before they were deleted in ascending order.

e - the TreeModelEvent of interest - javax.swing.event.TreeModelEvent

tree-structure-changed clj

(tree-structure-changed this e)

Invoked after the tree has drastically changed structure from a given node down. If the path returned by e.getPath is of length one and the first element does not identify the current root node the first element should become the new root of the tree.

e.path holds the path to the node. e.childIndices returns null.

e - the TreeModelEvent of interest - javax.swing.event.TreeModelEvent
