Example 1 with TreeCellEditor

use of javax.swing.tree.TreeCellEditor in project gephi by gephi.

the class DirectoryChooserUI method createTree.

private JComponent createTree() {
    final DirectoryHandler dirHandler = createDirectoryHandler(fileChooser);

Example 2 with TreeCellEditor

use of javax.swing.tree.TreeCellEditor in project intellij-community by JetBrains.

the class NewErrorTreeEditor method getTreeCellEditorComponent.

@Override
public Component getTreeCellEditorComponent(JTree tree, Object value, boolean selected, boolean expanded, boolean leaf, int row) {
    final ErrorTreeElement element = getElement(value);
    if (element instanceof EditableMessageElement) {
        EditableMessageElement editableMessageElement = (EditableMessageElement) element;
        final CustomizeColoredTreeCellRenderer leftSelfRenderer = editableMessageElement.getLeftSelfRenderer();
        final TreeCellEditor rightSelfEditor = editableMessageElement.getRightSelfEditor();
        myColoredTreeCellRenderer.setCurrentCallback(leftSelfRenderer);
        myRightCellRenderer.setCurrentCallback(rightSelfEditor);
        return myWrapperEditor.getTreeCellEditorComponent(tree, value, selected, expanded, leaf, row);
    }
    return myTree.getCellRenderer().getTreeCellRendererComponent(tree, value, selected, expanded, leaf, row, true);
