TreeTableViewSelectionModel

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 call SelectionModel.clearSelection() first, meaning that observers that are listening to the selected index property will not see the selected index being temporarily set to -1.

Clears the selection model of all selected indices.

This method will clear the selection of the item in the given index. If the given index is not selected, nothing will happen.

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.

Convenience method to inform if the given index is currently selected in this SelectionModel. Is functionally equivalent to calling getSelectedIndices().contains(index).

Returns the item at the given index. An example using ListView would be listView.getItems().get(index).

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().

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.

Convenience method to select all available indices.

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.

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.

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.

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.

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.

Selects the cells in the range (minRow, minColumn) to (maxRow, maxColumn), inclusive.

A read-only ObservableBuffer representing the currently selected cells in this TreeTableView. Rather than directly modify this list, please use the other methods provided in the TreeTableViewSelectionModel.

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.

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.

Returns the TreeTableView instance that this selection model is installed in.

Verifies if a object is equals to this delegate.

JavaFX object to be wrapped.
