processKeys

protected boolean processKeys(int keyCode)

Handle all standard keys of table. It should call in the key event handler from the implementation class.
Keys:

• pgup:
• up
• dn
• pgdn
• GralTable.keyMarkUp
• GralTable.keyMarkDn
• calls GralMng.getRegisteredUserAction(String what) with what="KeyAction" and invokes the returned action method. With them all standard key actions of this application may be done if a GralUserAction is registered for that.

Parameters:

keyCode - Encoding see KeyCode.

Returns:

true if the key is processed, false if the key is not processed here. Maybe processed after them.

setFocusCellMousePressed

protected void setFocusCellMousePressed()

setCellText

protected void setCellText(GralTable.CellData cell,
                           java.lang.String text)

Invoked on editing a text field

Parameters:

cell -

text -

getCellText

protected abstract java.lang.String getCellText(GralTable.CellData cell)

Gets the current text of the given cell from the graphic implementation.

Parameters:

cell -

Returns:

getCellTextFocus

protected abstract java.lang.String getCellTextFocus()

Gets the cell text from the focused cell in the implementation.

updateGraphicCellContent

protected void updateGraphicCellContent()

Updates the cell text fields which presents the content of the table. After them update() of the graphic level should be called. To execute the update of the cells in the graphic layer the #drawCellContent(int, CellData[], TableLineData, LinePresentation) is called inside for any cell. This method is implemented in the implementation layer.

setLineColors

private void setLineColors(GralTable.TableLineData line)

Sets the colors of the given line depending on the state

• line == GralTable.lineSelected :
  • marked: GralTable.TableLineData.colorBackSelectMarked or GralTable.colorBackSelectMarked
  • childrenMarked: GralTable.TableLineData.colorBackSelectSomeMarked or GralTable.colorBackSelectSomeMarked
  • not marked: GralTable.TableLineData.colorBackSelect or GralTable.colorBackSelect
• selected new: GralTable.colorBackSelectNewMarked or GralTable.colorBackSelectNew
• normal non selected line:
  • marked: GralTable.TableLineData.colorBackSelectMarked or GralTable.colorBackSelectMarked
  • childrenMarked: GralTable.TableLineData.colorBackSelectSomeMarked or GralTable.colorBackSelectSomeMarked
  • not focused: GralWidget.DynamicData.backColorNoFocus
  • not marked: GralTable.TableLineData.colorBackSelect or GralTable.colorBackSelect

Parameters:

line -

determineSizeAndPositionScrollbar

protected void determineSizeAndPositionScrollbar(int yPixel)

This method have to be called before the vertical scroll bar is painted in the GralWidgImplAccess_ifc.redrawGthread() routine.. It checks whether the GralTable#nLineCurr and the shown number of lines in GralTable.rootLine. GralTable.NodeTableLine.tbl_zLineUnfolded is given, e.g. >=0. If one of them is <0 or lines are countered calling GralTable.NodeTableLine.countChildren(boolean, int). Therewith the GralTable#nLineCurr is set too. Anytime if the situation is not specified the GralTable#nLineCurr can be set to -1. This forces new calculation.

resizeTable

protected void resizeTable(GralRectangle pixTable)

This routine will be called inside the resize listener of the implementation graphic. It calculates the width of the columns with the given width of the table's canvas. Then #setBoundsCells() will be called. That is implemented in the underlying graphic layer and sets the bounds for each cell.

Parameters:

pixTable - Size of the table area.

setBoundsCells

protected abstract void setBoundsCells(int treeDepthBase,
                                       int zLineVisible)

Invoked in resizeTable(GralRectangle) as action which should be implemented in the implementation layer. The xpixelCell was set before.

Parameters:

treeDepthBase -

remove

public boolean remove()

redrawTableWithFocusedCell

protected boolean redrawTableWithFocusedCell(GralTable.CellData data)

Sets the current cell as focused with the focus color. It causes a redraw of the whole table because the cell may be shifted in table position. TODO this method must call in the graphic thread yet, queue it with GralMng#setInfo(GralWidget, int, int, Object, Object).

Parameters:

cell - The cell

focusGainedTable

public void focusGainedTable()

This routine is invoked if any cell of the table gets the focus. It is if the window gets the focus from view of the whole operation system, if the mouse is landing on a cell Text-field with click or if setFocus() for the graphic presentation layer was called.

• If bFocusLost is true, another cell of this table has lost the focus in the last 50 ms before the repaint() was invoked. Then the super.GralWidget.setFocus() will not be called.
• If bRedrawPending is set, it means that the focus gained is invoked by a setFocus()-call of the graphic representation layer. Then the GralWidget.setFocus() will not be called.
• If both conditions are false, it is a focusGained either by mouse click, whereby this table has not have the focus before, or by any other action of focusing. Then GralWidget.setFocus() is called to designate, that the table is focused.

focusLostTable

protected void focusLostTable()

Invoked if any cell has lost the focus. If the table has lost the focus, the repaint will established this state after 50 milliseconds because the flag bFocused = false. But if another cell of the table has gotten the focus in this time, the bFocus = true is set.

protected void mouseDownGral(int key,
                             GralTable.CellData cell)
