Class TableHeaderRow

public final BooleanProperty reorderingProperty

Indicates if a reordering operation of a column is in progress. The value is true during a column reordering operation, and false otherwise. When a column is reordered (for example, by dragging its header), this property is updated automatically. Setting the value manually should be done when a subclass overrides the default reordering behavior. Calling setReorderingRegion(TableColumnHeader) before setting this property is required as well.

public TableHeaderRow(TableViewSkinBase skin)

Creates a new TableHeaderRow instance to visually represent the column header area of controls such as TableView and TreeTableView.

public final void setReordering(boolean value)

Sets the value of the reordering property.

public final boolean isReordering()

Gets the value of the reordering property.

public final BooleanProperty reorderingProperty()

Indicates if a reordering operation of a column is in progress. The value is true during a column reordering operation, and false otherwise. When a column is reordered (for example, by dragging its header), this property is updated automatically. Setting the value manually should be done when a subclass overrides the default reordering behavior. Calling setReorderingRegion(TableColumnHeader) before setting this property is required as well.

public final NestedTableColumnHeader getRootHeader()

Returns the root header for all columns. The root header is a NestedTableColumnHeader that contains the NestedTableColumnHeaders that represent each column. It spans the entire width of the TableView. This allows any developer overriding a TableColumnHeader to easily access the root header and all others TableColumnHeaders.

protected void updateScrollX()

Called whenever the value of the horizontal scrollbar changes in order to request layout changes, shifting the TableColumnHeaders.

For example, if custom components are added around a TableColumnHeader (such as icons above), they will also need to be shifted. When overriding, calling super() is required to shift the TableColumnHeaders, and it's up to the developer to notify its own custom components of this change.

protected void updateTableWidth()

Updates the table width when a resize operation occurs. This method is called continuously when the control width is resizing in order to properly clip this TableHeaderRow. Overriding this method allows a subclass to customize the resizing behavior.

Normally, the TableHeaderRow is using the full space (TableView width), but in some cases that space may be reduced. For example, if a vertical header that will display the row number is introduced, the TableHeaderRow would need to be clipped a bit shorter in order not to overlap that vertical header. Calling super() first when overriding this method allows Node.getClip() to compute the right width in order apply a transformation.

protected NestedTableColumnHeader createRootHeader()

Creates a new NestedTableColumnHeader instance. By default this method should not be overridden, but in some circumstances it makes sense (e.g. testing, or when extreme customization is desired).

protected void showColumnMenu(MouseEvent mouseEvent)

Shows a menu containing all leaf columns as items. An item can be selected/deselected to make the corresponding column visible/invisible.

protected TableColumnHeader getReorderingRegion()

Returns the current TableColumnHeader being moved during reordering.

protected void setReorderingRegion(TableColumnHeader reorderingRegion)

Sets the TableColumnHeader that is being moved during a reordering operation. This is automatically set by the TableColumnHeader when reordering starts. This method should only be called manually if the default reordering behavior is overridden. Calling setReordering(boolean) after the call is required.
