javax.swing.tree.FixedHeightLayoutCache — 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.

->fixed-height-layout-cache clj

(->fixed-height-layout-cache)

Constructor.

expanded? clj

(expanded? this path)

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

path - javax.swing.tree.TreePath

returns: boolean

get-bounds clj

(get-bounds this path place-in)

Returns a rectangle giving the bounds needed to draw path.

path - a TreePath specifying a node - javax.swing.tree.TreePath place-in - a Rectangle object giving the available space - java.awt.Rectangle

returns: a Rectangle object specifying the space to be used - 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, false otherwise - 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'll 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 horizontal component of the desired location - int y - the vertical component of the desired location - int

returns: the TreePath closest to the specified point - javax.swing.tree.TreePath

get-path-for-row clj

(get-path-for-row this row)

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

row - the row being queried - int

returns: the TreePath for the given row - javax.swing.tree.TreePath

get-row-count clj

(get-row-count this)

Returns the number of visible rows.

returns: the number of rows being displayed - int

get-row-for-path clj

(get-row-for-path this path)

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

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

returns: the row where the last item in path is visible or -1 if any elements in path aren't currently visible - int

get-visible-child-count clj

(get-visible-child-count this path)

Returns the number of visible children for row.

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

returns: the number of visible children for the specified 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 starting location for the enumeration - javax.swing.tree.TreePath

returns: the Enumerator starting at the desired location - java.util.Enumeration<javax.swing.tree.TreePath>

invalidate-path-bounds clj

(invalidate-path-bounds this path)

Does nothing, FixedHeightLayoutCache doesn't cache width, and that is all that could change.

path - the path being updated - 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 path being expanded or collapsed - javax.swing.tree.TreePath is-expanded - true if the path should be expanded, false otherwise - 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-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 rowHeight is less than or equal to 0 this will throw an IllegalArgumentException.

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 - 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 - 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 - 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 - javax.swing.event.TreeModelEvent
