Property Details:
- indentx, indenty
'indentx' and 'indenty' are used to define the minimal space between two nodes (indentx between leaf and node).
A node may exceed the size granted by 'indenty'. In this situation the node receives as much space it requires. The Rtl_tree deals with any node of any size.
The entire hierarchy will be redrawn, whenever 'indentx' and or 'indenty' is set.
- root
Either '0' or '1'. Root defines whether there is a visible parent node (the root node) for the hierarchy or not. If '0' is specified the single root node will be omitted. The nodes underneath root will then appear as roots of independent hierarchies.
The entire hierarchy will be redrawn, whenever 'root' is set.
- glyphs
Either '0' or '1'. The 'glyphs' property tells the Rtl_tree to replace the provided images with »glyphs«.
The »glyphs« and the providing font have to be specified inside the »option database«.
Example 4.3. Using a »glyphs« font
# Assume the tree’s path: .tree option add *tree.glyphFontFamily Windings option add *tree.glyphFontSize 18
glyphFontFamily and glyphFontSize are used instead of »glyphFont« in order to directly use them with 'ptext' from TkPathExample 4.4. Using glyphs
# Assume image : _picture # Assume tree’s path : .tree option add *tree._picture__glyph k # …or via class # option add *Rtl_tree._picture__glyph m
- foreground, background
Any Colour.
The entire hierarchy will be redrawn after 'foreground' or 'background' was set.
'background' is currently faulty. Some columns may not being updated after background was set. In consequence the column colour may remain wrong until either 'foreground' is set or a node modified (open/close).
- hasChildrenfcn, requestChildrenfcn, openfcn
On demand node management. These »callback« functions are called to refresh the data inside the the Rtl_tree.
See the
rtl_tree.tclto learn more about callback functions. There is a rather longish comment in that module.- dragfcn, contextfcn, selectfcn
The interactive »call back« functions used by the Rtl_tree.
