|Description|Add-on for [[MoveablePanelPlugin]]: Panel Manager Menu, Control Panel, and Map Viewer |
Track position/size of moveable panels using named //panel maps//. Interactive graphical map viewer provides "bird's eye" view of entire document for quick navigation between panels and management of panel layouts.
!!!//''PLEASE NOTE: this is an experimental addition to MoveablePanelPlugin. It is currently a __BETA release for testing and review purposes only__, and is subject to change without notice or regard for backward-compatibility with this or other versions of this plugin. Do not rely on this release for production-ready purposes!''//

*''menu''<br>instead of adding the mouse handling to the containing panel, the macro will render just the Panel Manager menu button. This allows you to embed the button anywhere in your document (e.g., in the main menu or sidebar) to provide a fixed location for always accessing the current panel layout. When ''menu'' is specified, you can use ''label:...'' and ''prompt:...'' to override the default button text (≡) and tooltip to suit your purposes. If you provide a ''name:...'' parameter along with ''menu'', then only the section of the Panel Manager menu that applies to that named panel will be included in the resulting menu (to control a single, specific panel).
*''maps''<br>embeds a popup list of all panel maps stored in the document, permitting you to quickly switch between panel maps just by selecting a map form the popup list.
*''load''<br>embeds a command link that loads the panel map specified by the ''name:...'' parameter.
*''viewer''<br>embeds a graphical, interactive panel map viewer and page navigator in your tiddler content. You can specify the maximum width and height of the embedded viewer using the ''size:...'' parameter with CSS units of measure (e.g., px, em, cm, in, %). If the size is not specified, the default is for the viewer to fit the element in which it rendered (i.e., using the 'auto' or '100%' CSS value). The ''viewer'' display is updated //live// as panels are docked/undocked, moved, size, folded, etc.
*''table''<br>embeds a panel map data table viewer in your tiddler content. This table shows the x, y, w, h, and z, values associated with each panel stored in the current map. As with the ''viewer'', the ''table'' data is automatically updated when panels are changed.
*''commands''<br>embeds the panel map management commands (i.e., ''new'', ''load'', ''edit'', ''save'', and ''view table...'').
// more documentation pending... //

!!!!!Open issues
<<<
Known problems:
* IE: Popups appear as a vertical line when X > window width (i.e., the core assumes left side of page)... maybe a CSS clipping issue?
* IE: 'zoomed in' mapsize calculation is way off. These equations need to be re-examined for all browsers.
Additional features (for later):
* Track hover/docked states (in addition to x,y,w,h,z,folded)
* Drag outline in map to scroll page
* Option to normalize z-range when saving maps
<<<
!!!!!Configuration
<<<
<<option chkPanelManagerUseCookies>> remember panel maps between sessions (enables cookies)
<<option chkMoveablePanelShowStatus>> show position/size while moving/resizing a panel
<<option chkMoveablePanelShowManager>> add Panel Manager button to all undocked panels
<<option chkPanelManagerAutoMap>> automatically show map viewer as soon as popup menu is opened
<<option chkPanelManagerMapFullPage>> show full page (zoom out) in map viewer (no scrollbars)
Popup map viewer display size (maximum width and height): {{fourchar{<<option txtPanelManagerPopupMapSize>>}}}
^^//(use CSS dimensions, leave blank or use 'auto' to fit to container)//^^
<<<
!!!!!Examples

!Description
Bring your TiddlyWiki to life!
!Notes
To install you will need to paste a line of text into your Theme {{{ <div id="tagmindmap"></div>}}} in the location where you would like to see the visualisation.
Currently we are unable to support this working in internet explorer.. we are working on it however.. sorry! :(
!Usage
{{{
The tagmindmap can be created from a macro call using <<tiddlytagmindmap //params//>>
alternatively paste <div id='tagmindmap'></div> into your page template.
The following macros may be useful however they can be included in the toolbar settings of the tiddlytagmindmap macro.
<<ToggleTagMindMap id>> (create button to toggle mind map with id 'id' on/off)
<<LoadMindMap id>> (create button to load all nodes into mind map with id 'id')
There are a variety of configuration options in the backstage area under tweak. They all begin with TiddlyTagMindMapPlugin:
}}}
!!Parameters
tiddlytagmindmap takes several (but all optional) parameters. Some examples can be seen below, note the order is irrelevant of these parameters.
!!!Nodes and Edges
!!!!Directional edges
The directed parameter allows you to add arrowheads to your edges. usage: <<tiddlytagmindmap directed:true>>
!!!!Name Length
nodeNameLength:x where x is an integer will shorten the name of any node with a name longer than x. If x =0, the labels will disappear so you can rely on tooltips.
!!!!Variable node sizes (tagcloud)
notagcloud:true as a parameter will flatten the nodes to have the same size font
!!!Dimensions
{{{<<tiddlytagmindmap height:100 width:100>>}}} will set a tiddlytagmindmap with height and width 100.
!!!Zooming
A parameter zoom allows you to specify an integer representing the initial inflation of the mind map. The smaller it is - the closer the nodes will be together.
{{{<<tiddlytagmindmap zoom:1000>>}}} will give you a very inflated TagMindMap!
!!!Breadcrumb trail
You can turn visited nodes red when they are clicked on by using the {{{breadcrumb:true}}} parameter by default this is false.
!!!The toolbar
A parameter toolbar is a string of 1s. These signify the buttons. The first digit sets whether the bar should appear vertically or horizontally.
The following digits turn off or on the other available buttons.
!!!!The buttons
The digits preceding the first digit represent these buttons in this order..
toggle, loadall
{{{<<tiddlytagmindmap toolbar:101>>}}} would give you a vertical toolbar with a loadall button
!!!The Start State
A parameter can be used to specify how the map looks on start up.
Currently the options are empty OR all OR a custom executable javascript function.
The first two options are simple strings eg.
{{{<<tiddlytagmindmap startState:empty>>}}} loads a blank tag mind map however {{{<<tiddlytagmindmap startState:all>>}}} loads all nodes excluding those in the exclude List.
the latter is more interesting. Have a look at [[Example 2]]!
!Revision History
1.5 xx/xx
*Ability to add arrow heads to show direction
*better performance
*better control panel: replacement of macros for toggle/zoom in and out with built in toolbar to plugin
*update to new version of RGraph (JIT)
*Ability to set meta-data specific to nodes within a tiddler in optional fields see
http://TiddlyWiki.abego-software.de/#PartTiddlerPlugin (eg. colouring of children/parents/images in node label)
*definable meta data (prefix,suffix,label,color)
*can turn off click function
1.4 11/08 tag cloud integration/multiple tag mind maps/ability to call from macro
1.3 22/10/08 working with ie/packaged up code
!To Do
*bug: zoomin breaks on more than 1 mind map.. no idea why but scale resets :(
*fix ie clicking nodes
*display tiddler loads below the place it;s called from
*Ability to define your own function for relative sizing (ie. you could weight them on some meta field)
*color property should become css property
*ability to resize using %
*distinguish between tags and tiddlers (see CreateNodeJSON - tiddlers that don't exist in store are tagged in data field)
*rss hooks - specify where tags and node names come from in feed
*ability to specify what click function is
*ability to stop displayTiddler from loading into graph (*ability to turn off dynamic as you go updates)
*allow resizing
*auto spread out messy nodes (ie. zoom out if nodes are too close)
*node repositioning and saving of state
*better css support
*performance issues
*deleting edges as tiddlers are deleted
*adapt to parabolic tree mode and other visualisation types
*Self-defined click functions
*Continued code cleanup
*breadcrumbs to become encoded in the node colour (rather than label colour) define a colour of the breadcrumb trail - make it change colour each click (increment colour, so you can get an idea of path you took to get somewhere)
*add pins to locations in the mind map to jump back to (definable in meta data long term, also short term in tiddler edit menu)

Removes one or more edges from the visualization. It can also perform several animations like fading sequentially, fading concurrently, iterating or replotting.
Parameters:
viz - The visualization object (an RGraph instance in this case).
vertex - An array having two strings which are the ids of the nodes connected by this edge: ['id1', 'id2']. Can also be a two dimensional array holding many edges: [['id1', 'id2'], ['id3', 'id4'], ...].
opt - Animation options. It's an object with two properties: _type_, which can be _nothing_, _replot_, _fade:seq_, _fade:con_ or _iter_. The other property is the _duration_ in milliseconds.
