ListAdapter
public ListAdapter(JXList component)
Constructs aListAdapter
for the specified target JXList.- Parameters:
component
- the target list.
-
-
Method Detail
-
getList
public JXList getList()
Typesafe accessor for the target component.- Returns:
- the target component as a
JXList
-
hasFocus
public boolean hasFocus()
Returns true if the cell identified by this adapter currently has focus. Otherwise, it returns false.- Specified by:
hasFocus
in classComponentAdapter
- Returns:
- true if the cell identified by this adapter currently has focus; Otherwise, return false
-
getRowCount
public int getRowCount()
Returns the number of rows in the target's data model.- Overrides:
getRowCount
in classComponentAdapter
- Returns:
- the number of rows in the target's data model.
-
getValue
public java.lang.Object getValue()
Returns the value of the cell identified by this adapter. That is, for the at position (adapter.row, adapter.column) in view coordinates.NOTE: this implementation assumes that view coordinates == model coordinates, that is simply calls getValueAt(this.row, this.column). It is up to subclasses to override appropriately is they support model/view coordinate transformation.
Overridden to return value at implicit view coordinates.
- Overrides:
getValue
in classComponentAdapter
- Returns:
- the value of the cell identified by this adapter
- See Also:
ComponentAdapter.getValueAt(int, int)
,ComponentAdapter.getFilteredValueAt(int, int)
,ComponentAdapter.getValue(int)
-
getValueAt
public java.lang.Object getValueAt(int row, int column)
Returns the value of the target component's cell identified by the specified row and column in model coordinates.- Specified by:
getValueAt
in classComponentAdapter
- Parameters:
row
- in model coordinatescolumn
- in model coordinates- Returns:
- the value of the target component's cell identified by the specified row and column
-
getFilteredValueAt
public java.lang.Object getFilteredValueAt(int row, int column)
Returns the filtered value of the cell identified by the row in view coordinate and the column in model coordinates. Note: the asymetry of the coordinates is intentional - clients like Highlighters are interested in view values but might need to access non-visible columns for testing. While it is possible to access row coordinates different from the current (that is this.row) it is not safe to do so for row > this.row because the adapter doesn't allow to query the count of visible rows.- Specified by:
getFilteredValueAt
in classComponentAdapter
- Parameters:
row
- the row of the cell in view coordinatescolumn
- the column of the cell in model coordinates.- Returns:
- the filtered value of the cell identified by the row in view coordinate and the column in model coordiantes
-
getFilteredStringAt
public java.lang.String getFilteredStringAt(int row, int column)
Returns the String representation of the filtered value of the cell identified by the row in view coordinate and the column in model coordinates.Note: the asymetry of the coordinates is intentional - clients like Highlighters are interested in view values but might need to access non-visible columns for testing. While it is possible to access row coordinates different from the current (that is this.row) it is not safe to do so for row > this.row because the adapter doesn't allow to query the count of visible rows.
This implementation messages the StringValue.TO_STRING with the filteredValue, subclasses should re-implement and use the api appropriate for the target component type.
PENDING JW: what about null cell values? StringValue has a contract to return a empty string then, would that be okay here as well?
- Overrides:
getFilteredStringAt
in classComponentAdapter
- Parameters:
row
- the row of the cell in view coordinatescolumn
- the column of the cell in model coordinates.- Returns:
- the String representation of the filtered value of the cell identified by the row in view coordinate and the column in model coordiantes
-
getString
public java.lang.String getString()
Returns the String representation of the value of the cell identified by this adapter. That is, for the at position (adapter.row, adapter.column) in view coordinates.NOTE: this implementation assumes that view coordinates == model coordinates, that is simply calls getValueAt(this.row, this.column). It is up to subclasses to override appropriately is they support model/view coordinate transformation.
This implementation messages the StringValue.TO_STRING with the getValue, subclasses should re-implement and use the api appropriate for the target component type.
- Overrides:
getString
in classComponentAdapter
- Returns:
- the String representation of value of the cell identified by this adapter
- See Also:
ComponentAdapter.getValueAt(int, int)
,ComponentAdapter.getFilteredValueAt(int, int)
,ComponentAdapter.getValue(int)
-
getStringAt
public java.lang.String getStringAt(int row, int column)
Returns the String representation of the value of the cell identified by the row specified row and column in model coordinates.This implementation messages the StringValue.TO_STRING with the valueAt, subclasses should re-implement and use the api appropriate for the target component type.
- Overrides:
getStringAt
in classComponentAdapter
- Parameters:
row
- in model coordinatescolumn
- in model coordinates- Returns:
- the value of the target component's cell identified by the specified row and column
-
setValueAt
public void setValueAt(java.lang.Object aValue, int row, int column)
Sets the value of the target component's cell identified by the specified row and column in model coordinates.- Specified by:
setValueAt
in classComponentAdapter
- Parameters:
aValue
- the value to setrow
- in model coordinatescolumn
- in model coordinates
-
isCellEditable
public boolean isCellEditable(int row, int column)
Determines whether this cell is editable.- Specified by:
isCellEditable
in classComponentAdapter
- Parameters:
row
- the row to query in model coordinatescolumn
- the column to query in model coordinates- Returns:
true
if the cell is editable,false
otherwise
-
isEditable
public boolean isEditable()
Returnstrue
if the cell identified by this adapter is editable,false
otherwise.- Specified by:
isEditable
in classComponentAdapter
