TableViewSelectionModel
Builds a default TableViewSelectionModel instance with the provided TableView.- Parameters:
tableView
- The TableView upon which this selection model should operate.- Throws:
NullPointerException
- TableView can not be null.
-
-
Method Details
-
getSelectedCells
A read-only ObservableList representing the currently selected cells in this TableView. Rather than directly modify this list, please use the other methods provided in the TableViewSelectionModel.- Returns:

isSelected
Convenience function which tests whether the given row and column index is currently selected in this table instance. If the table control is in its 'cell selection' mode (where individual cells can be selected, rather than entire rows), and if the column argument is null, this method should return true only if all cells in the given row are selected.- Specified by:
isSelected
in classTableSelectionModel<S>

getSelectedIndices
Description copied from class:MultipleSelectionModel
Returns a read-only ObservableList of all selected indices. The ObservableList will be updated by the selection model to always reflect changes in selection. This can be observed by adding a
ListChangeListener
to the returned ObservableList.- Specified by:
getSelectedIndices
in classMultipleSelectionModel<T>
- Returns:
- the list of selected indices
-
getSelectedItems
Description copied from class:MultipleSelectionModel
Returns a read-only ObservableList of all selected items. The ObservableList will be updated further by the selection model to always reflect changes in selection. This can be observed by adding a
ListChangeListener
to the returned ObservableList.- Specified by:
getSelectedItems
in classMultipleSelectionModel<T>
- Returns:
- the list of selected items
-
clearAndSelect
public void clearAndSelect(int row) Description copied from class:SelectionModel
A method that clears any selection prior to setting the selection to the given index. The purpose of this method is to avoid having to callSelectionModel.clearSelection()
first, meaning that observers that are listening to theselected index
property will not see the selected index being temporarily set to -1.- Specified by:
clearAndSelect
in classSelectionModel<T>
- Parameters:
row
- The index that should be the only selected index in this selection model.
-
select
public void select(int row) Description copied from class:SelectionModel
This will select the given index in the selection model, assuming the index is within the valid range (i.e. greater than or equal to zero, and less than the total number of items in the underlying data model).
If there is already one or more indices selected in this model, calling this method will not clear these selections - to do so it is necessary to first call
SelectionModel.clearSelection()
.If the index is already selected, it will not be selected again, or unselected. However, if multiple selection is implemented, then calling select on an already selected index will have the effect of making the index the new selected index (as returned by
SelectionModel.getSelectedIndex()
.- Specified by:
select
in classSelectionModel<T>
- Parameters:
row
- The position of the item to select in the selection model.
-
select
Description copied from class:SelectionModel
This method will attempt to select the index that contains the given object. It will iterate through the underlying data model until it finds an item whose value is equal to the given object. At this point it will stop iterating - this means that this method will not select multiple indices.
- Specified by:
select
in classSelectionModel<T>
- Parameters:
obj
- The object to attempt to select in the underlying data model.
-
selectIndices
public void selectIndices(int row, int... rows) Description copied from class:MultipleSelectionModel
This method allows for one or more selections to be set at the same time. It will ignore any value that is not within the valid range (i.e. greater than or equal to zero, and less than the total number of items in the underlying data model). Any duplication of indices will be ignored.
If there is already one or more indices selected in this model, calling this method will not clear these selections - to do so it is necessary to first call clearSelection.
The last valid value given will become the selected index / selected item.
- Specified by:
selectIndices
in classMultipleSelectionModel<T>
- Parameters:
row
- the first index to selectrows
- zero or more additional indices to select
-
selectAll
public void selectAll()Description copied from class:MultipleSelectionModel
Convenience method to select all available indices.
- Specified by:
selectAll
in classMultipleSelectionModel<T>
-
selectFirst
public void selectFirst()Description copied from class:MultipleSelectionModel
This method will attempt to select the first index in the control. If clearSelection is not called first, this method will have the result of selecting the first index, whilst retaining the selection of any other currently selected indices.
If the first index is already selected, calling this method will have no result, and no selection event will take place.
- Specified by:
selectFirst
in classMultipleSelectionModel<T>
-
selectLast
public void selectLast()Description copied from class:MultipleSelectionModel
This method will attempt to select the last index in the control. If clearSelection is not called first, this method will have the result of selecting the last index, whilst retaining the selection of any other currently selected indices.
If the last index is already selected, calling this method will have no result, and no selection event will take place.
- Specified by:
selectLast
in classMultipleSelectionModel<T>
-
clearSelection
public void clearSelection(int index) Description copied from class:SelectionModel
This method will clear the selection of the item in the given index. If the given index is not selected, nothing will happen.
- Specified by:
clearSelection
in classSelectionModel<T>
- Parameters:
index
- The selected item to deselect.
-
clearSelection
public void clearSelection()Description copied from class:SelectionModel
Clears the selection model of all selected indices.
- Specified by:
clearSelection
in classSelectionModel<T>
-
isSelected
public boolean isSelected(int index) Description copied from class:SelectionModel
Convenience method to inform if the given index is currently selected in this SelectionModel. Is functionally equivalent to calling
getSelectedIndices().contains(index)
.- Specified by:
isSelected
in classSelectionModel<T>
- Parameters:
index
- The index to check as to whether it is currently selected or not.- Returns:
- True if the given index is selected, false otherwise.
-
isEmpty
public boolean isEmpty()Description copied from class:SelectionModel
This method is available to test whether there are any selected indices/items. It will return true if there are no selected items, and false if there are.- Specified by:
isEmpty
in classSelectionModel<T>
- Returns:
- Will return true if there are no selected items, and false if there are.
-
selectPrevious
public void selectPrevious()Description copied from class:SelectionModel
This method will attempt to select the index directly before the current focused index. If clearSelection is not called first, this method will have the result of selecting the previous index, whilst retaining the selection of any other currently selected indices.
Calling this method will only succeed if:
- There is currently a lead/focused index.
- The lead/focus index is not the first index in the control.
- The previous index is not already selected.
If any of these conditions is false, no selection event will take place.
- Specified by:
selectPrevious
in classSelectionModel<T>
-
selectNext
public void selectNext()Description copied from class:SelectionModel
This method will attempt to select the index directly after the current focused index. If clearSelection is not called first, this method will have the result of selecting the next index, whilst retaining the selection of any other currently selected indices.
Calling this method will only succeed if:
- There is currently a lead/focused index.
- The lead/focus index is not the last index in the control.
- The next index is not already selected.
If any of these conditions is false, no selection event will take place.
- Specified by:
selectNext
in classSelectionModel<T>
