Overview consists hierarchy of visuals
The Visual Hierarchy tool can be used to overview the
consists_of hierarchy of visual
objects. It is commonly used to find the PCE reference for visual
objects from the screen or to examine the structure of a tool (in terms
of the visual objects
it is built from).
The tool consists of a graphical window for displaying the hierarchy
and a dialog. The graphical window displays the hierarchy. The root of
the hierarchy is the PCE predefined object @display_manager
and is always present.
User interface:
Any XPCE graphical
object from the screen may be added to the tree by positioning the
pointer (mouse) on the object and pressing META-SHIFT-CONTROL-V.
Mnemonic: V for Visual and all modifiers to avoid conflict
with applications.
Each node of the hierarchy has a menu associated with the right
button. This menu has the following entries:
FLASH Send ->flash to the represented graphical
=============================================
EXPAND Expand the next level of the hierarchy
EXPAND TREE Expand as many levels as possible
COLLAPSE Remove all subtrees
DELETE Remove this node and anything below
=============================================
SOURCE View source of class of object
INSPECT Start _Inspector_ on object
TILE HIERARCHY Frames: analyse the tile structure
CLASS BROWSER Start _ClassBrowser_ on class of object..
=============================================
FREE Send ->free to the object
POSTSCRIPT Genererate a PostScript description
The following button bindings are defined:
- LEFT
->Flash the object and print the output of
portray_object/1 in the dialog. The
reference of the object is put on the X-display clipboard for pasting in
another application (typically the Prolog window for further analysis of
the object).- DOUBLE - LEFT
- Expand the next level of the hierarchy.
Tool name: visual_hierarchy
Bugs:
