Property Details
-
tableColumn
A property that refers to theTableColumnBase
instance that this header is visually represents.- See Also:
getTableColumn()
-
-
Constructor Details
-
TableColumnHeader
Creates a new TableColumnHeader instance to visually represent the givenTableColumnBase
instance.- Parameters:
tc
- The table column to be visually represented by this instance.
-
-
Method Details
-
getTableColumn
Gets the value of the property tableColumn.- Property description:
- A property that refers to the
TableColumnBase
instance that this header is visually represents.
-
tableColumnProperty
A property that refers to theTableColumnBase
instance that this header is visually represents.- See Also:
getTableColumn()
-
layoutChildren
protected void layoutChildren()Invoked during the layout pass to layout the children in thisParent
. 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 classParent
-
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 classRegion
- 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 classRegion
- 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 classRegion
- Parameters:
width
- the width that should be used if preferred height depends on it- Returns:
- the computed preferred height for this region
-
getCssMetaData
This method should delegate toNode.getClassCssMetaData()
so that a Node's CssMetaData can be accessed without the need for reflection.- Specified by:
getCssMetaData
in interfaceStyleable
- Overrides:
getCssMetaData
in classRegion
- Returns:
- The CssMetaData associated with this node, which may include the CssMetaData of its superclasses.
-
queryAccessibleAttribute
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 classParent
- Parameters:
attribute
- the requested attributeparameters
- optional list of parameters- Returns:
- the value for the requested attribute
- See Also:
AccessibleAttribute
-
getTableHeaderRow
Returns theTableHeaderRow
associated with thisTableColumnHeader
.- Returns:
- the
TableHeaderRow
associated with thisTableColumnHeader
- Since:
- 12
-
getTableSkin
Returns theTableViewSkinBase
in which thisTableColumnHeader
is inserted. This will returnnull
until theTableHeaderRow
has been set.- Returns:
- the
TableViewSkinBase
in which thisTableColumnHeader
is inserted, ornull
- Since:
- 12
-
resizeColumnToFitContent
protected void resizeColumnToFitContent(int maxRows)Resizes thisTableColumnHeader
's column to fit the width of its content.- Implementation Requirements:
- The resulting column width for this implementation is the maximum of the preferred width of the header
cell and the preferred width of the first
maxRow
cells.Subclasses can either use this method or override it (without the need to call
super()
) to provide their custom implementation (such as ones that exclude the header, excludenull
content, compute the minimum width, etc.). - Parameters:
maxRows
- the number of rows considered when resizing. If -1 is given, all rows are considered.- Since:
- 14
-
getClassCssMetaData
Returns 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
-
