TWiki Web>TreeBrowserPlugin (30 Mar 2007, StephaneLenclud? ) (raw view)EditAttach
---+!! Tree Browser Plugin

Renders a bulleted or numbered list as a collapsible/expandable tree of nodes.

%TOC%

---++ Acknowledgment

This plugin leverages the [[http://www.destroydrop.com/javascripts/tree/][dTree]] !JavaScript tree menu by [[mailto:drop@destroydrop.com][Geir Landrö]] as well as code borrowed from TWiki:Plugins.RenderListPlugin.

---++ Syntax Rules

Place the tag =%<nop>TREEBROWSER{= _parameters_ =}%= immediately before a bulleted or numbered list. The lists can be handcrafted, generated by another Plugin, a =%<nop>TOC%=, or the result of a %TWIKIWEB%.FormattedSearch. The list will be rendered in a tree-like fashion (similar to the explorer folder list). Whenever a new indentation level is started, the subsequent nodes at this or a lower indentation level are shown as descendents of the preceding node. The following parameters can be used to configure the appearance of the tree:
| *Parameter* | *Description* | *Default* |
| ="name"= or%BR% =theme="name"= | Select a rendering theme | none |
| =title= | Required. This text serves as the root of the tree | none |
| =openAll= | If =on=, the tree is shown fully expanded. | =off= |
| =openTo= | Must be an integer. If present, the tree is expanded to the given node, as numbered from the root. | =0= |
| =shared= | Must be a string. If present, the state of the tree is shared across all trees using this string. For example, if the tree is used in the WebLeftBar, the state will hold at all topics with this WebLeftBar. It's basically the name of the JavaScript object representing your tree. | none |
| =uselines= | Set to =false= if you don't want to show lines linking nodes and leafs in the tree | =true= |
| =useplusminus= | Set to =false= if you don't want to show '-' and '+' signs. One can use something like =onclick='javascript: tree.o($index);'= in the tree item to trigger opening/closing of a node. | =true= |
| =noindent= | Set to =true= to show children at the level of their parent. It suppresses children indentation. Enabling =noindent= will disable =uselines= and =useplusminus=. | =false= |
| =nocss= | Set to =true= to prevent inclusion of =dtree.css=. | =false= |
| =closesamelevel= | If =true= only one node within a parent can be expanded at the same time. openAll() and closeAll() functions do not work when this is enabled. | =false= |
| =noroot= | Prevents rendering of the title line. Useful if you don't want to show any title. | =false= |
| =warn= | Text to be displayed if no tree was found. | none |
| =style= | Name of the CSS file to include without the =.css= extension. The CSS file must be attached to this topic. | =dtree= |
| =autotoggle= | Set to =on= will enable node open/close when clicking the node item. Typically used for menu style tree along with =noindent=. | =off= |
| =nodeactions= | Defines node functionality in a comma separated list of HTML event and dTree function. Typically used for menu style tree along with =noindent=. Format: <verbatim><event> <function>[,...]</verbatim> =event= is an HTML event e.g. =onclick=, =ondblclick=, =onmouseover=, =onmouseout=... %BR% =function= is one of the three dTree functions: =open=, =close=, =toggle= | none |
| =popup= | Set to =on= to enable pop-up menu mode. Typically used with =closesamelevel=. See [[%TOPIC%#Pop_up_example][pop-up menu example]]. | =off= |
| =closepopupdelay= | Pop-up mode only. Delay in millisecond before all popup close once the mouse cursor has left the menu structure. | =1000= |
| =popupoffset= | Provides x and y offset from parent node for pop-up menus. Allows for fine tunning of pop-up position. | =0,0= |
| =firstpopupoffset= | Provides x and y offset for first level pop-up menus. Introduce as a workaround for PatternSkin issues. | =0,0= |
| =useopacity= | Used to generate extra =dtreeTransluscentBackground= =div=. Enables popup with translucent background and opaque text. | =off= |

Rendering themes can be defined by =&lt;name&gt;_THEME= Plugin settings
   * Each theme is defined by a comma separated list containing the render type and parameters required by that render type
   * There are different render types; currently this Plugin supports *tree* and *icon* render types
   * Format of the *tree* render type:
      * =Set &lt; _name_ &gt;_THEME = tree=
   * Format of the *icon* render type:
      * =Set &lt; _name_ &gt;_THEME = icon, [&lt; _root icon image_ &gt;], [&lt; _icon image_ &gt;], [&lt; _folder icon image_ &gt;], [&lt; _open folder icon image_ &gt;]=
      * The _root icon image_ is shown at the root of the tree, the _icon image_ is shown at every leaf node, the _folder icon image_ is shown at every collapsed internal node, and the _open folder icon image_ is shown at every expanded internal node. The icon images point to files attached to TWiki topics and are referenced in the standard manner. If no path is given, the images are taken from TWiki.TWikiDocGraphics.
      * If an icon image is omitted, the following defaults are chosen: %ATTACHURL%/empty.gif, %ATTACHURL%/page.gif, %ATTACHURL%/folder.gif, %ATTACHURL%/folderopen.gif

If !JavaScript is not enabled, the list is rendered as usual, and the =%<nop>TREEBROWSER% tag is omitted.

---+++ Bullets

   * Use regular ==*== bullets
   * Start with level one
      * Increase indentation only one level at a time
         * =Like this=
   * Decreasing indentation many levels at a time is fine
   * Keep labels short as text does not wrap.
   * You can specify an icon for a bullet of render type *tree* or *icon*:
      * Attach the icon to a topic, e.g. =myicon.gif=, or
      * Use one of the existing icons: %ATTACHURL%/globe.gif =%<nop>ATTACHURL%/globe.gif=, %ATTACHURL%/home.gif =%<nop>ATTACHURL%/home.gif=, %ATTACHURL%/virtualhome.gif =%<nop>ATTACHURL%/virtualhome.gif=, %ATTACHURL%/group.gif =%<nop>ATTACHURL%/group.gif=, %ATTACHURL%/persons.gif =%<nop>ATTACHURL%/persons.gif=, %ATTACHURL%/virtualpersons.gif =virtualpersons.gif=, %ATTACHURL%/person.gif =%<nop>ATTACHURL%/person.gif=, %ATTACHURL%/virtualperson.gif =%<nop>ATTACHURL%/virtualperson.gif=, %ATTACHURL%/email.gif =%<nop>ATTACHURL%/email.gif=, %ATTACHURL%/trend.gif =%<nop>ATTACHURL%/trend.gif=, %ATTACHURL%/folder.gif =%<nop>ATTACHURL%/folder.gif=, %ATTACHURL%/file.gif =%<nop>ATTACHURL%/file.gif=, %ATTACHURL%/doc.gif =%<nop>ATTACHURL%/doc.gif=, %ATTACHURL%/image.gif =%<nop>ATTACHURL%/image.gif=, %ATTACHURL%/pdf.gif =%<nop>ATTACHURL%/pdf.gif=, %ATTACHURL%/ppt.gif =%<nop>ATTACHURL%/ppt.gif=, %ATTACHURL%/sound.gif =%<nop>ATTACHURL%/sound.gif=, %ATTACHURL%/xls.gif =%<nop>ATTACHURL%/xls.gif=, %ATTACHURL%/zip.gif =%<nop>ATTACHURL%/zip.gif=, %ATTACHURL%/see.gif =%<nop>ATTACHURL%/see.gif=
      * Refer to an attached icon at the beginning of the bullet with:
         * =icon:myicon.gif Followed by normal bullet text=
      * Refer to any icon at the beginning of the bullet using a full path or URL:
         * =icon:%ICONURL{"xls"}% Followed by normal bullet text=


---++ CSS classes

A number of classes are used to facilitate look and feel customizations through CSS.

---+++ Constant class

This class won't change from one tree to the other:
   * =treeBrowserPlugin=: given to the =div= element encapsulating the whole tree and javascript.

---+++ Variable classes

Those classes are prefixed with the =style= parameter. For clarity of the documentation we used the default =dtree= prefix. 
Variable classes allow for multiple tree =style= support on one page.

   * =dtree=: given to the =div= element encapsulating the whole tree. Since v0.1.
   * =dtreeRoot=: given to the =div= element encapsulating the root or title of the tree. Introduced in v1.1.
   * =dtreeLeaf=: given to the =div= element encapsulating a tree item without children. Introduced in v0.9.
   * =dtreeNodeOpened=: given to the =div= element encapsulating a tree item that is showing children. Introduced in v0.9.
   * =dtreeNodeClosed=: given to the =div= element encapsulating a tree item that is hiding children. Introduced in v0.9.
   * =dtreeChildren=: given to the =div= element encapsulating the children of a tree item. Changed in v0.9. Formerly =clip=.
   * =dtreeLevel0=: given to the =div= element encapsulating the children of the tree root item. Introduced in v0.9.
   * =dtreeLevel1=: given to the =div= element encapsulating the children of level 0 items. Introduced in v0.9.
   * =dtreeLevel2=: given to the =div= element encapsulating the children of level 1 items. Introduced in v0.9.
   * =dtreeLeveln=: given to the =div= element encapsulating the children of level n-1 items. Introduced in v0.9.
   * =dtreeTransluscentBackground=: given to the =div= element used for popup translucent background. Introduced in v1.5.
   * =dtreeFakeItem=: given to the =div= element simulating nodes and leaf in =dtreeTransluscentBackground=. It guarantees same size for the translucent background and actual =dtreeChildren= =div=. Typically you should give =dtreeFakeItem= the same margin and padding properties as for =dtreeLeaf=, =dtreeNodeOpened= and =dtreeNodeclosed=. Introduced in v1.5.

This tree could be used in the TWiki.WebLeftBar, for example. Clicking on the plus icon next to =Webs= will expand the subtree below that node.

To add _"collapse/expand all nodes"_ functionalities do something like:
<verbatim><a href="javascript: tree.openAll();">open all</a> | <a href="javascript: tree.closeAll();">close all</a>

---++ Known issues

   * PatternSkin prevents javascript to determine menu position in topic content. Use =firstpopupoffset="-163,0"= as a workaround.
   * NatSkin CSS =natMainContent= =overflow:hidden= causes =z-index= bug in !FireFox. Workaround by removing or overriding =overflow:hidden= for =natMainContent=.
   * =dtreeTranslucentBackground= only works for pop-up and not level 0. Sizing issue... 
   * Pop-up sub-menu won't work on IE for =dmenu= style. Workaround by using =smenu=.
