Property inspectors

Create the image

You can optionally create the image that appears in the Property inspector.

1 Create an image that is 36 pixels wide and 36 pixels high.

2 Save the image as marquee.gif in Configuration/Inspectors.

In general, you can save images for Property inspectors in any format that Dreamweaver supports.

Test the Property inspector

Finally, you can test the Property inspector.

1 Restart Dreamweaver.

2 Create a new HTML page, or open an existing HTML page.

3 Add the following in the body section of the page:

4 Highlight the text you just added.

The Property inspector you created for the marquee tag appears.

5 Enter a value for the direction attribute in the Property inspector.

The tag on your page changes to include the direction attribute and the value you entered in the Property inspector.

The Property inspector API functions

Two of the Property inspector API functions (canInspectSelection() and inspectSelection()) are required.

canInspectSelection()

Description

Determines whether the Property inspector is appropriate for the current selection.

Arguments

None.

Note: Use dom.getSelectedNode() to get the current selection as a JavaScript object (for more information about

dom.getSelectedNode(), see the Dreamweaver API Reference).

Returns

Dreamweaver expects a Boolean value: true if the inspector can inspect the current selection; false otherwise.

Example

The following instance of the canInspectSelection() function returns a true value if the selection contains the

CLASSID attribute, and the value of that attribute is "clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" (the class

ID for Adobe Flash Player):

1 2 ... 220 221 222 223 224 225 226 227 228 229 230 ... 386 387
