void | aceptarTeclaPresionada(KeyEvent e, JTable pTabla, JTextField pTextoDeBusqueda, int pColumna) aceptar Tecla Presionada if (pTabla.getRowCount() <= 0) return; if (e.getKeyCode() == KeyEvent.VK_DOWN) { if (pTabla.getRowCount() - 1 > pTabla.getSelectedRow()) { showCell(pTabla, pTabla.getSelectedRow() + 1, 0); if (pTextoDeBusqueda != null) setearTextoDeBusqueda(pTabla, pTextoDeBusqueda, pColumna); } else if (e.getKeyCode() == KeyEvent.VK_UP) { if (pTabla.getSelectedRow() > 0) { showCell(pTabla, pTabla.getSelectedRow() - 1, 0); if (pTextoDeBusqueda != null) setearTextoDeBusqueda(pTabla, pTextoDeBusqueda, pColumna); } else if (e.getKeyCode() == KeyEvent.VK_PAGE_DOWN) { int vNum = (int) java.lang.Math .round(pTabla.getVisibleRect().getHeight() / (pTabla.getRowHeight() + pTabla.getRowMargin())); if ((pTabla.getRowCount() > pTabla.getSelectedRow()) && ((pTabla.getSelectedRow() + vNum) <= pTabla.getRowCount())) showCell(pTabla, pTabla.getSelectedRow() + vNum, 0); else showCell(pTabla, pTabla.getRowCount() - 1, 0); if (pTextoDeBusqueda != null) setearTextoDeBusqueda(pTabla, pTextoDeBusqueda, pColumna); } else if (e.getKeyCode() == KeyEvent.VK_PAGE_UP) { int vNum = (int) java.lang.Math .round(pTabla.getVisibleRect().getHeight() / (pTabla.getRowHeight() + pTabla.getRowMargin())); if ((pTabla.getSelectedRow() > 0) && ((pTabla.getSelectedRow() - vNum) >= 0)) showCell(pTabla, pTabla.getSelectedRow() - vNum, 0); else showCell(pTabla, 0, 0); if (pTextoDeBusqueda != null) setearTextoDeBusqueda(pTabla, pTextoDeBusqueda, pColumna); |
void | addSpaceSelection(final JTable table, final int column) If this table has a editable boolean column, the user can press space to toggle the selection of the selected rows for the column. table.putClientProperty("JTable.autoStartsEdit", Boolean.FALSE); table.addKeyListener(new KeyAdapter() { @Override public void keyReleased(KeyEvent e) { if (e.getKeyCode() == KeyEvent.VK_SPACE) { TableModel model = table.getModel(); for (int row : table.getSelectedRows()) { int rowModel = table.convertRowIndexToModel(row); ... |
void | ajustarAnchoColumnas(JTable table) ajustar Ancho Columnas TableColumnModel columnModel = table.getColumnModel(); for (int col = 0; col < table.getColumnCount(); col++) { int maxwidth = 0; for (int row = 0; row < table.getRowCount(); row++) { TableCellRenderer rend = table.getCellRenderer(row, col); Object value = table.getValueAt(row, col); Component comp = rend.getTableCellRendererComponent(table, value, false, false, row, col); maxwidth = Math.max(comp.getPreferredSize().width, maxwidth); ... |
boolean | buscarDescripcion(KeyEvent e, JTable pTabla, JTextField pTextoDeBusqueda, int pColumna) buscar Descripcion boolean findRecord = false; if ((e.getKeyChar() != KeyEvent.CHAR_UNDEFINED) && (e.getKeyCode() != KeyEvent.VK_ENTER)) { String vFindText = pTextoDeBusqueda.getText().toUpperCase(); String vDescrip = ""; for (int k = 0; k < pTabla.getRowCount(); k++) { vDescrip = ((String) pTabla.getValueAt(k, pColumna)).toUpperCase().trim(); if (vDescrip.length() >= vFindText.length()) { vDescrip = vDescrip.substring(0, vFindText.length()); ... |
TableColumn | cloneTableColumn(TableColumn c) clone Table Column TableColumn result = new TableColumn(c.getModelIndex(), c.getPreferredWidth(), c.getCellRenderer(),
c.getCellEditor());
result.setMaxWidth(c.getMaxWidth());
result.setMinWidth(c.getMinWidth());
result.setResizable(c.getResizable());
result.setHeaderValue(c.getHeaderValue());
result.setHeaderRenderer(c.getHeaderRenderer());
result.setIdentifier(c.getIdentifier());

TableColumnModel | cloneTableColumnModel(TableColumnModel m) clone Table Column Model DefaultTableColumnModel result = new DefaultTableColumnModel(); for (int i = 0; i < m.getColumnCount(); i++) result.addColumn(cloneTableColumn(m.getColumn(i))); return result; |
C | columnAt(final JTable table, final Point p, final Class column At return columnClazz.getEnumConstants()[table.columnAtPoint(p)];
|
int | convertColumnIndexToModel(TableColumnModel cm, int viewColumnIndex) Maps the index of the column in the view at viewColumnIndex to the index of the column in the table model. if (viewColumnIndex < 0) { return viewColumnIndex; return cm.getColumn(viewColumnIndex).getModelIndex(); |
int | convertColumnIndexToView(TableColumnModel model, int modelCol) convert Column Index To View if (modelCol < 0) return modelCol; for (int viewCol = 0; viewCol < model.getColumnCount(); viewCol++) { if (model.getColumn(viewCol).getModelIndex() == modelCol) { return viewCol; return -1; ... |
int[] | convertSelectedColumnsToModelIndices(JTable table, int[] columns) convert Selected Columns To Model Indices int[] convertedCols = new int[columns.length]; for (int i = 0; i < columns.length; i++) { convertedCols[i] = table.convertColumnIndexToModel(columns[i]); return convertedCols; |
