CellRendererPane()

addAccessibleSelection(int)

Adds the nth selected item in the object to the object's selection.

addImpl(Component, Object, int)

If the specified component is already a child of this then we don't bother doing anything - stacking order doesn't matter for cell renderer components (CellRendererPane doesn't paint anyway).<

clearAccessibleSelection()

Clears the selection in the object, so that nothing in the object is selected.

doAccessibleAction(int)

Perform the nth Action on the object

getAccessibleActionCount()

Returns the number of Actions available in this object If there is more than one, the first one is the "default" action (if any action is considered "default").

 public void paintComponent(Graphics g,
                            Component c,
                            Container p,
                            int x,
                            int y,
                            int w,
                            int h,
                            boolean shouldValidate)

Paint a cell renderer component c on graphics object g. Before the component is drawn it's reparented to this (if that's neccessary), it's bounds are set to w,y and the graphics object is (effectively) translated to x,y. After the component is painted it's bounds are reset to -w, -h, 0, 0 so that, if it's the last renderer component painted, it will not start consuming input. The Container p is the component we're actually drawing on, typically it's equal to this.getParent(). If shouldValidate is true the component c will be validated before painted.

 public void paintComponent(Graphics g,
                            Component c,
                            Container p,
                            int x,
                            int y,
                            int w,
                            int h)

Invokes paintComponent(g, c, p, x, y, w, h, false).

 public void paintComponent(Graphics g,
                            Component c,
                            Container p,
                            Rectangle r)

Calls this.paintComponent() with the rectangles x,y,width,height fields.

 public Accessible getNextAccessibleSibling()

Get the next sibling of this Accessible, if a preferred one exists. This should generally return the next item in the tab order, if that item implements Accessible

Returns:

the next Accessible, if there is one

 public Accessible getPreviousAccessibleSibling()

Get the previous sibling of this Accessible, if a preferred one exists. This should generally return the previous item in the tab order, if that item implements Accessible

Returns:

the previous Accessible, if there is one

 public Accessible getAccessibleAt(Point p)

Returns the Accessible child contained at the local coordinate Point, if one exists.

Returns:

the Accessible at the specified location, if it exists

 public String getAccessibleName()

Get the accessible name of this object. This should almost never return java.awt.Component.getName(), as that generally isn't a localized name, and doesn't have meaning for the user. If the object is fundamentally a text object (e.g. a menu item), the accessible name should be the text of the object (e.g. "save"). If the object has a tooltip, the tooltip text may also be an appropriate String to return.

Returns:

the localized name of the object -- can be null if this object does not have a name

See Also:

setAccessibleName

 public void setAccessibleName(String s)

Set the localized accessible name of this object.

Parameters:

s - the new localized name of the object.

See Also:

getAccessibleName

 public String getAccessibleDescription()

Get the accessible description of this object. This should be a concise, localized description of what this object is - what is it's meaning to the user. If the object has a tooltip, the tooltip text may be an appropriate string to return, assuming it contains a concise description of the object (instead of just the name of the object - e.g. a "Save" icon on a toolbar that had "save" as the tooltip text shouldn't return the tooltip text as the description, but something like "Saves the current text document" instead).

Returns:

the localized description of the object -- can be null if this object does not have a description

See Also:

setAccessibleDescription

 public void setAccessibleDescription(String s)

Set the accessible description of this object.

Parameters:

s - the new localized description of the object

See Also:

getAccessibleDescription

 public AccessibleStateSet getAccessibleStateSet()

Get the state of this object.

Returns:

an instance of AccessibleStateSet containing the current state set of the object

See Also:

AccessibleState

 public AccessibleRole getAccessibleRole()

Get the role of this object.

Returns:

an instance of AccessibleRole describing the role of the object

See Also:

AccessibleRole

 public String getAccessibleValue()

Get the value of this object as a String. This should almost never return java.Object.toString(), as that is not a localized, human readable representation of the value of the object.

Returns:

human readable value of the object -- can be null if this object does not have a value

 public Accessible getAccessibleParent()

Get the Accessible parent of this object. If the parent of this object implements Accessible, this method should simply return getParent().

Returns:

the Accessible parent of this object -- can be null if this object does not have an Accessible parent

 public int getAccessibleChildrenCount()

Returns the number of accessible children in the object. If all of the children of this object implement Accessible, than this method should return the number of children of this object.

Returns:

the number of accessible children in the object.

 public Accessible getAccessibleChild(int i)

Return the nth Accessible child of the object.

Parameters:

i - zero-based index of child

Returns:

the nth Accessible child of the object

 public int getAccessibleActionCount()

Returns the number of Actions available in this object If there is more than one, the first one is the "default" action (if any action is considered "default").

Returns:

the number of Actions in this object

 public String getAccessibleActionDescription(int i)

Return a description of the nth action of the object. This description should be human-readable; by default it currently isn't...

Parameters:

i - zero-based index of the actions

Returns:

a description of the nth action

 public boolean doAccessibleAction(int i)

Perform the nth Action on the object

Parameters:

i - zero-based index of actions

Returns:

whether the action was performed or not.

 public AccessibleText getAccessibleText()

Gets the AccessibleText interface for the component. If the component does not speak AccessibleText, or have a proxy which does, this method returns null.

Returns:

the AccessibleText of the object.

See Also:

AccessibleText

 public int getAccessibleSelectionCount()

Returns the number of items currently selected. If no items are selected, the return value will be 0.

Returns:

the number of items currently selected.

 public Accessible getAccessibleSelection(int i)

Returns an Accessible representing the nth selected item in the object. If there isn't a selection, or there are fewer items selcted than the integer passed in, the return value will be null.

Parameters:

i - the zero-based index of selected items

Returns:

an Accessible containing the selected item

 public void addAccessibleSelection(int i)

Adds the nth selected item in the object to the object's selection. If the object supports multiple selections, (the method getAccessibleStateSet returns a state that is MULTISELECTABLE) the nth item is added to any existing selection, otherwse it replaces any existing selection in the objct. If the nth item is already selected, this method has no effect.

Parameters:

i - the zero-based index of selectable items

See Also:

getAccessibleStateSet

 public void removeAccessibleSelection(int i)

Removes the nth selected item in the object from the object's selection. If the nth item isn't currently selected, this method has no effect.

Parameters:

i - the zero-based index of selectable items

 public void clearAccessibleSelection()

Clears the selection in the object, so that nothing in the object is selected.

 public void selectAllAccessibleSelection()

Causes every selected item in the object to be selected, if the object supports multiple selections (if getAccessibleStateSet returns a state that is MULTISELECTABLE).

See Also:

getAccessibleStateSet
