This is determined by checking the visibility of the object and ancestors of the object. Note: this will return true even if the object is obscured by another (for example, it happens to be underneath a menu that was pulled down). Specified by: `isShowing` in interface `javax.accessibility.AccessibleComponent` Returns: true if object is showing; otherwise, false
	isVisible	`boolean` isVisible() Determines if the object is visible. public boolean isVisible() Description copied from class: `Component.AccessibleAWTComponent` Determines if the object is visible. Note: this means that the object intends to be visible; however, it may not in fact be showing on the screen because one of the objects that this object is contained by is not visible. To determine if an object is showing on the screen, use `isShowing`. Specified by: `isVisible` in interface `javax.accessibility.AccessibleComponent` Returns: true if object is visible; otherwise, false See Also: `AccessibleComponent.setVisible(boolean)`, `AccessibleContext.getAccessibleStateSet()`, `AccessibleState.VISIBLE`, `AccessibleStateSet`
	removeFocusListener	`void` removeFocusListener(FocusListener l) Removes the specified focus listener so it no longer receives focus events from this component. public void removeFocusListener(FocusListener l) Description copied from class: `Component.AccessibleAWTComponent` Removes the specified focus listener so it no longer receives focus events from this component. Specified by: `removeFocusListener` in interface `javax.accessibility.AccessibleComponent` Parameters: `l` - the focus listener See Also: `AccessibleComponent.addFocusListener(java.awt.event.FocusListener)`
	removePropertyChangeListener	`void` removePropertyChangeListener(java.beans.PropertyChangeListener listener) Remove a PropertyChangeListener from the listener list. public void removePropertyChangeListener(java.beans.PropertyChangeListener listener) Description copied from class: `Component.AccessibleAWTComponent` Remove a PropertyChangeListener from the listener list. This removes a PropertyChangeListener that was registered for all properties. Overrides: `removePropertyChangeListener` in class `javax.accessibility.AccessibleContext` Parameters: `listener` - The PropertyChangeListener to be removed
	requestFocus	`void` requestFocus() Requests focus for this object. public void requestFocus() Description copied from class: `Component.AccessibleAWTComponent` Requests focus for this object. Specified by: `requestFocus` in interface `javax.accessibility.AccessibleComponent` See Also: `AccessibleComponent.isFocusTraversable()`
	setAccessibleDescription	`void` setAccessibleDescription(java.lang.String s) Sets the accessible description of this object. public void setAccessibleDescription(java.lang.String s) Description copied from class: `javax.accessibility.AccessibleContext` Sets the accessible description of this object. Changing the name will cause a PropertyChangeEvent to be fired for the ACCESSIBLE_DESCRIPTION_PROPERTY property. Parameters: `s` - the new localized description of the object See Also: `AccessibleContext.setAccessibleName(java.lang.String)`, `AccessibleContext.addPropertyChangeListener(java.beans.PropertyChangeListener)`
	setAccessibleName	`void` setAccessibleName(java.lang.String s) Sets the localized accessible name of this object. public void setAccessibleName(java.lang.String s) Description copied from class: `javax.accessibility.AccessibleContext` Sets the localized accessible name of this object. Changing the name will cause a PropertyChangeEvent to be fired for the ACCESSIBLE_NAME_PROPERTY property. Parameters: `s` - the new localized name of the object. See Also: `AccessibleContext.getAccessibleName()`, `AccessibleContext.addPropertyChangeListener(java.beans.PropertyChangeListener)`
	setAccessibleParent	`void` setAccessibleParent(javax.accessibility.Accessible a) Sets the Accessible parent of this object. public void setAccessibleParent(javax.accessibility.Accessible a) Description copied from class: `javax.accessibility.AccessibleContext` Sets the Accessible parent of this object. This is meant to be used only in the situations where the actual component's parent should not be treated as the component's accessible parent and is a method that should only be called by the parent of the accessible child. Parameters: `a` - - Accessible to be set as the parent
	setBackground	`void` setBackground(Color c) Sets the background color of this object. public void setBackground(Color c) Description copied from class: `Component.AccessibleAWTComponent` Sets the background color of this object. (For transparency, see `isOpaque`.) Specified by: `setBackground` in interface `javax.accessibility.AccessibleComponent` Parameters: `c` - the new `Color` for the background See Also: `Component.isOpaque()`
	setBounds	`void` setBounds(Rectangle r) Sets the bounds of this object in the form of a `Rectangle` object. public void setBounds(Rectangle r) Description copied from class: `Component.AccessibleAWTComponent` Sets the bounds of this object in the form of a `Rectangle` object. The bounds specify this object's width, height, and location relative to its parent. Specified by: `setBounds` in interface `javax.accessibility.AccessibleComponent` Parameters: `r` - a rectangle indicating this component's bounds See Also: `AccessibleComponent.getBounds()`
	setCursor	`void` setCursor(Cursor cursor) Sets the `Cursor` of this object. public void setCursor(Cursor cursor) Description copied from class: `Component.AccessibleAWTComponent` Sets the `Cursor` of this object. The method may have no visual effect if the Java platform implementation and/or the native system do not support changing the mouse cursor shape. Specified by: `setCursor` in interface `javax.accessibility.AccessibleComponent` Parameters: `cursor` - the new `Cursor` for the object See Also: `AccessibleComponent.getCursor()`
	setEnabled	`void` setEnabled(boolean b) Sets the enabled state of the object. public void setEnabled(boolean b) Description copied from class: `Component.AccessibleAWTComponent` Sets the enabled state of the object. Specified by: `setEnabled` in interface `javax.accessibility.AccessibleComponent` Parameters: `b` - if true, enables this object; otherwise, disables it See Also: `AccessibleComponent.isEnabled()`
	setFont	`void` setFont(Font f) Sets the `Font` of this object. public void setFont(Font f) Description copied from class: `Component.AccessibleAWTComponent` Sets the `Font` of this object. Specified by: `setFont` in interface `javax.accessibility.AccessibleComponent` Parameters: `f` - the new `Font` for the object See Also: `AccessibleComponent.getFont()`
	setForeground	`void` setForeground(Color c) Sets the foreground color of this object. public void setForeground(Color c) Description copied from class: `Component.AccessibleAWTComponent` Sets the foreground color of this object. Specified by: `setForeground` in interface `javax.accessibility.AccessibleComponent` Parameters: `c` - the new `Color` for the foreground See Also: `AccessibleComponent.getForeground()`
	setLocation	`void` setLocation(Point p) Sets the location of the object relative to the parent. public void setLocation(Point p) Description copied from class: `Component.AccessibleAWTComponent` Sets the location of the object relative to the parent. Specified by: `setLocation` in interface `javax.accessibility.AccessibleComponent` Parameters: `p` - the coordinates of the object See Also: `AccessibleComponent.getLocation()`
	setSize	`void` setSize(Dimension d) Resizes this object so that it has width and height. public void setSize(Dimension d) Description copied from class: `Component.AccessibleAWTComponent` Resizes this object so that it has width and height. Specified by: `setSize` in interface `javax.accessibility.AccessibleComponent` Parameters: `d` - - the dimension specifying the new size of the object See Also: `AccessibleComponent.getSize()`
	setVisible	`void` setVisible(boolean b) Sets the visible state of the object. public void setVisible(boolean b) Description copied from class: `Component.AccessibleAWTComponent` Sets the visible state of the object. Specified by: `setVisible` in interface `javax.accessibility.AccessibleComponent` Parameters: `b` - if true, shows this object; otherwise, hides it See Also: `AccessibleComponent.isVisible()`
