Class TableColumnHeader

    • Constructor Detail

      • TableColumnHeader

        public TableColumnHeader​(TableColumnBase tc)
        Creates a new TableColumnHeader instance to visually represent the given TableColumnBase instance.
        Parameters:
        tc - The table column to be visually represented by this instance.

    • Method Detail

      • getTableColumn

        public final TableColumnBase<?,?> getTableColumn​()
        Gets the value of the property tableColumn.
        Property description:
        A property that refers to the TableColumnBase instance that this header is visually represents.

      • layoutChildren

        protected void layoutChildren​()
        Invoked during the layout pass to layout the children in this Parent. By default it will only set the size of managed, resizable content to their preferred sizes and does not do any node positioning.

        Subclasses should override this function to layout content as needed.

        Overrides:
        layoutChildren in class Parent

      • computePrefWidth

        protected double computePrefWidth​(double height)
        Computes the preferred width of this region for the given height. Region subclasses should override this method to return an appropriate value based on their content and layout strategy. If the subclass doesn't have a VERTICAL content bias, then the height parameter can be ignored.
        Overrides:
        computePrefWidth in class Region
        Parameters:
        height - the height that should be used if preferred width depends on it
        Returns:
        the computed preferred width for this region

      • computeMinHeight

        protected double computeMinHeight​(double width)
        Computes the minimum height of this region. Returns the sum of the top and bottom insets by default. Region subclasses should override this method to return an appropriate value based on their content and layout strategy. If the subclass doesn't have a HORIZONTAL content bias, then the width parameter can be ignored.
        Overrides:
        computeMinHeight in class Region
        Parameters:
        width - the width that should be used if min height depends on it
        Returns:
        the computed minimum height for this region

      • computePrefHeight

        protected double computePrefHeight​(double width)
        Computes the preferred height of this region for the given width; Region subclasses should override this method to return an appropriate value based on their content and layout strategy. If the subclass doesn't have a HORIZONTAL content bias, then the width parameter can be ignored.
        Overrides:
        computePrefHeight in class Region
        Parameters:
        width - the width that should be used if preferred height depends on it
        Returns:
        the computed preferred height for this region

      • queryAccessibleAttribute

        public Object queryAccessibleAttribute​(AccessibleAttribute attribute,
                                       Object... parameters)
        This method is called by the assistive technology to request the value for an attribute.

        This method is commonly overridden by subclasses to implement attributes that are required for a specific role.
        If a particular attribute is not handled, the superclass implementation must be called.

        Overrides:
        queryAccessibleAttribute in class Parent
        Parameters:
        attribute - the requested attribute
        parameters - optional list of parameters
        Returns:
        the value for the requested attribute
        See Also:
        AccessibleAttribute

      • getClassCssMetaData

        public static List<CssMetaData<? extends Styleable,?>> getClassCssMetaData​()
        Returnst the CssMetaData associated with this class, which may include the CssMetaData of its superclasses.
        Returns:
        the CssMetaData associated with this class, which may include the CssMetaData of its superclasses
