Initializes the item property from the content data. Each list item must implement this method to provider initialization of its own and call
.initialize(MLItemProp)
- Specified by:
initialize
in interfaceIContentData<MLItemProp>
- Parameters:
item
- The item.
getLeadingTextColumn
protected int getLeadingTextColumn()Returns the column index for the leading text. Types supporting description text must override this method.- Specified by:
getLeadingTextColumn
in classMLItem
- Returns:
- The column index, or -1 for none.
getDescriptionColumn
protected int getDescriptionColumn()Returns the column index for the description. Types supporting description text must override this method.- Specified by:
getDescriptionColumn
in classMLItem
- Returns:
- The column index, or -1 for none.
refreshFromVS
public void refreshFromVS(int[] columns) Refreshes contents from VirtualSpace.- Specified by:
refreshFromVS
in interfaceIContentData<MLItemProp>
- Specified by:
refreshFromVS

- Parameters:
columns
- The connected table columns indicies, -1 for none.
getTrailingText

- true for changed, false for no change.
isTrailingTextOppositeAligned
public boolean isTrailingTextOppositeAligned()Returns if the trailing text is aligned to the opposite side, i.e. leading instead of trailing.- Returns:
- true if trailing text is aligned to leading side, false for aligned to the trailing side.
setTrailingTextOppositeAligned
public boolean setTrailingTextOppositeAligned(boolean opposite) Sets if the trailing text is aligned to the opposite side, i.e. leading instead of trailing.- Parameters:
opposite
- Alignment flag: true if trailing text is aligned to leading side, false for aligned to the trailing side.- Returns:
- true for changed, false for no change.
getTrailingTextWrap
public int getTrailingTextWrap()Gets option for trailing text wrap.- Returns:
- The trailing text wrap, multiple(0), single line(1), ellipsis(2).

method in case listeners are added by others.- Specified by:
onArrowInvoked
in interfaceIMLArrowActionListener
- Parameters:
