setCollapsedIcon
public static void setCollapsedIcon(javax.swing.JTree tree, javax.swing.Icon icon)
Set's the collapsed icon to use for the givenJTree
if that tree's UI delegate exetends fromBasicTreeUI
. If the given tree's UI delegate does not extend fromBasicTreeUI
then the given tree will not be changed.- Parameters:
tree
- the tree to set the collapsed icon for.icon
- the new collapsed icon to use.- See Also:
BasicTreeUI.setCollapsedIcon(javax.swing.Icon)
-
setExpandedIcon
public static void setExpandedIcon(javax.swing.JTree tree, javax.swing.Icon icon)
Set's the expanded icon to use for the givenJTree
if that tree's UI delegate extends fromBasicTreeUI
. If the given tree's UI delegate does not extend fromBasicTreeUI
then the given tree will not be changed.- Parameters:
tree
- the tree to set the expanded icon for.icon
- the new collapsed icon to use.- See Also:
BasicTreeUI.setExpandedIcon(javax.swing.Icon)
-
setLeftChildIndent
public static void setLeftChildIndent(javax.swing.JTree tree, int indent)
Set's the left indent in pixels to use for the givenJTree
's collapsed and expanded icon. This value in conjuction with the right indent comprises the total amount of space that the collapsed and expanded icon draw into. If the given tree's UI delegate does not extend fromBasicTreeUI
then the given tree will not be changed.- Parameters:
tree
- the tree to set the left indent for.indent

's collapsed and expanded icon. This value in conjuction with the left indent comprises the total amount of space that the collapsed and expanded icon draw into. If the given tree's UI delegate does not extend fromBasicTreeUI
then the given tree will not be changed.- Parameters:
tree
- the tree to set the right indent for.indent
- the new left indent in pixels.- See Also:
BasicTreeUI.setRightChildIndent(int)
-
repaintSelection
public static void repaintSelection(javax.swing.JTree tree)
Repaints the selection. This allows the row selection to have a background color that changes based on the focus state of the component.- Parameters:
tree
