1st JAVA Navigator - Commander [Tab Panel

Tab Panel - Tree Component

The Tree Component page of the Commander is used to set the individual nodes (branches) of the Tree part of the applet.

Options set on this page (other than the default icons) relate to the SELECTED node only.

1st JAVA Navigator - Commander - Tab Panel - Tree

	Adding tree node on same level To add a new node on at the same level as the selected node. A pop up box will then appear asking whether to place the new node directly above or below the selected node.

	Adding child tree nodes To add a new node as a child branch of the selected node.

	Deleting tree nodes To delete the selected node.

	Re-arranging tree nodes To move or copy nodes within the tree. Simply drag and drop them to the desired position within the tree. ie: Just select, click and drag them with the mouse, releasing them on the node where you wish to shift them to.

Options

From the dialogue box, select one of these options:

Move and insert as CHILD:
Moves the node that was selected and dragged, and inserts it a "child" of the node on which it was dropped.
ie: The copied node will be placed one level lower in the tree hierarchy than the node on which it is dropped.

Move and insert on SAME level:
Moves the selected node and inserts it directly above the selected node, on the same level in the tree hierarchy.

Copy and insert as CHILD:
Copies the node that was selected and dragged, and inserts it as a "child" of the node on which it was dropped.
ie: The copied node will be placed one level lower in the tree hierarchy than the node on which it is dropped.

Copy and insert on SAME level:
Copies the selected node and inserts it directly above the selected node, on the same level in the tree hierarchy.


Note	The dialogue box requires that the selected option is double-clicked.

	Node text The text entered here is the text which is displayed on the currently selected node.

	Status bar text This text will be shown within the status bar during a Tree node mouse-over event. (The status bar is the text bar at the bottom of the window.)

	Link URL 1 The first Link URL which will be executed when the selected node is clicked.

	Target frame 1 The target frame in which the first Link URL will be opened. Page Default = (none) Same Frame = ( _self) Whole Window = ( _top) New Window = ( _blank) Parent Frame = ( _parent) Alternatively, choose your own name (eg: MyFrame)

Example

Splitting the window into 2 frames using the following HTML code:
<frameset framespacing="0" frameborder="0" border="0" cols="245,*">
<frame src="MyContent.htm" name="ContentFrame">
<frame src="MyMain.htm" name="MyFrame"></frameset>

This means:
- The left frame is named: "ContentFrame".
It will show the HTML file: "MyContent.htm" and include the selected applet.
- The right frame is named: "MyFrame".
It will show the HTML file: "MyMain.htm".

Note

If further explanation of the terminology above is required, please refer to the documentation that comes with your HTML editor about frames.

	Target frame 2 The target frame in which the second Link URL will be opened.


	Open expanded If set (and the node has children) then it will be shown, expanded.

	Adding images (tree icons) Additional images (icons) may be added to the image slider. A standard Windows File Open dialog box will open to the "jimages" file. (as shown below)

1st JAVA Navigator - Commander - Tab Panel - Tree - Opening Images for Addition to List


Tip	You may add your own icons, but they must be a valid gif format (16 x 16 pixels). Add even more great images from Auscomp's FREE 3D Icon Library - compliments of Auscomp - World Wide.

Scroll back to top

	Node images Choose an image (icon) from the image slider in the Node Images section. To assign this icon to the node, click on the Set button. If the selected node is to be a leaf node (ie has no child nodes): Set only the Leaf icon. If the selected node is to be a parent node: Set icons for both Expanded and Collapsed.

	Default images To help speed up the loading process, default icons may be set. These icons are chosen in the same way as the images for each node. They will be applied to any node where no icons are specified - except where the icons are disabled on the Tree Style page of the Commander.


Tip	To help speed up the applet loading time for your users, set the default icons or use no icons.
