The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.
    Parameters:
    
    parent - a tree control which will be the parent of the new instance (cannot be null)
    
    style - the style of control to construct

The text, icon and other attributes of the item are set to the default value. If the tree was created with the SWT.VIRTUAL style, these attributes are requested again as needed. Parameters: index - the index of the item to clear recursive - true if all child items of the indexed item should be cleared recursively, and false otherwise Throws: java.lang.IllegalArgumentException - ERROR_INVALID_RANGE - if the index is not between 0 and the number of elements in the list minus 1 (inclusive) SWTException - ERROR_WIDGET_DISPOSED - if the receiver has been disposed ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver See Also: SWT.VIRTUAL, SWT.SetData setImage public void setImage(Image image) Description copied from class: Item Sets the receiver's image to the argument, which may be null indicating that no image should be displayed. Overrides: setImage in class Item Parameters: image - the image to display on the receiver (may be null) setImage public void setImage(int index, Image image) Sets the receiver's image at a column. Parameters: index - the column index image - the new image Throws: java.lang.IllegalArgumentException - ERROR_INVALID_ARGUMENT - if the image has been disposed SWTException - ERROR_WIDGET_DISPOSED - if the receiver has been disposed ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver setImage public void setImage(Image[] value) Sets the image for multiple columns in the tree. Parameters: value - the array of new images Throws: java.lang.IllegalArgumentException - ERROR_NULL_ARGUMENT - if the array of images is null ERROR_INVALID_ARGUMENT - if one of the images has been disposed SWTException - ERROR_WIDGET_DISPOSED - if the receiver has been disposed ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver clearAll public void clearAll(boolean recursive) Clears all the items in the receiver. The text, icon and other attributes of the items are set to their default values. If the tree was created with the SWT.VIRTUAL style, these attributes are requested again as needed. Parameters: recursive - true if all child items should be cleared recursively, and false otherwise Throws: SWTException - ERROR_WIDGET_DISPOSED - if the receiver has been disposed ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver See Also: SWT.VIRTUAL, SWT.SetData getItems public TreeItem[] getItems() Returns a (possibly empty) array of TreeItems which are the direct item children of the receiver. Note: This is not the actual structure used by the receiver to maintain its list of items, so modifying the array will not affect the receiver. Returns: the receiver's items Throws: SWTException - ERROR_WIDGET_DISPOSED - if the receiver has been disposed ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver getItem public TreeItem getItem(int index) Returns the item at the given, zero-relative index in the receiver. Throws an exception if the index is out of range. Parameters: index - the index of the item to return Returns: the item at the given index Throws: java.lang.IllegalArgumentException - ERROR_INVALID_RANGE - if the index is not between 0 and the number of elements in the list minus 1 (inclusive) SWTException - ERROR_WIDGET_DISPOSED - if the receiver has been disposed ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver getItemCount public int getItemCount() Returns the number of items contained in the receiver that are direct item children of the receiver. Returns: the number of items Throws: SWTException - ERROR_WIDGET_DISPOSED - if the receiver has been disposed ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver indexOf public int indexOf(TreeItem item) Searches the receiver's list starting at the first item (index 0) until an item is found that is equal to the argument, and returns the index of that item. If no item is found, returns -1. Parameters: item - the search item Returns: the index of the item Throws: java.lang.IllegalArgumentException - ERROR_NULL_ARGUMENT - if the tool item is null ERROR_INVALID_ARGUMENT - if the tool item has been disposed SWTException - ERROR_WIDGET_DISPOSED - if the receiver has been disposed ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver removeAll public void removeAll() Removes all of the items from the receiver. Throws: SWTException - ERROR_WIDGET_DISPOSED - if the receiver has been disposed ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver setItemCount public void setItemCount(int count) Sets the number of child items contained in the receiver. Parameters: count - the number of items Throws: SWTException - ERROR_WIDGET_DISPOSED - if the receiver has been disposed ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
