WOQuickTime

WOQuickTime is a dynamic element that you can use to incorporate QuickTime objects (movie, sound, VR, ...) into your WebObjects applications. The WOQuickTime API is essentially based on the QuickTime plug-ins API.

WOQuickTime supports QuickTime VR with hotspots. If you specify a list of hotspots and the user clicks inside the QuickTime VR object, the method specified by the action attribute is performed and the selection attribute is set to the value of the selected hotspot.

You should use WOQuickTime components outside of an HTML form.

Synopsis

Bindings

WOQuickTime has the following attributes. Those attributes relevant only to VR movies are indicated with "[VR]" in the description.

filename

Path to the QuickTime object relative to the WebServerResources directory.

src

URL locating the QuickTime object. Use this attribute for complete URLs; for relative URLs use filename instead.

framework

The framework that contains the QuickTime object. This attribute is only necessary if the QuickTime object is in a different location from the component. That is, if the component and the QuickTime object are both in the application or if the component and the QuickTime object are both in the same framework, this attribute isn't necessary. If the QuickTime object is in a framework and the component is in the application, specify the framework's name here (minus the .framework extension). If the QuickTime object should be in the application but the component is in a framework, specify the "app" keyword in place of the framework name.

width

QuickTime object width in pixels. The width attribute is required. Never specify a width of less than 2 as this can cause problems with some browsers. If you are trying to hide the movie, use the hidden attribute instead. If you don't know the width of the movie, open your movie with MoviePlayer (it comes with QuickTime) and select Get Info from the Movie menu. If you don't use the scale attribute and you supply a width that is smaller than the actual width of the movie, the movie will be cropped to fit. If you supply a width that is greater than the width of the movie, the movie will be centered inside this width.

height

Quicktime object height in pixels. If you want to display the movie's controller, you'll need to add 16 pixels to the height. height is required unless you use the hidden attribute. Never specify a height of less than 2 as this can cause problems with some browsers. If you are trying to hide the movie, use the hidden attribute instead. If you don't know the height of the movie, open your movie with MoviePlayer and select Get Info from the Movie menu. If you do not use the scale attribute and you supply a height that is smaller than the actual height of the movie (plus 16 if you are showing the controller), the movie will be cropped to fit. If you supply a height that is greater than the height of the movie, the movie will be centered inside this height.

pluginsPage

This optional attribute allows you to specify a URL from which the user can fetch the necessary plug-in if it is not installed. This attribute is handled by your browser. If your browser cannot find the plug-in when loading your page, it will warn the user and allow them to bring up the specified URL. Generally this parameter should be set to "http://www.apple.com/quicktime". This attribute is appropriate for both QuickTime movies and QuickTime VR Objects and Panoramas.

hotspotList

[VR] The hotspot list is an array of strings, each of which should be mapped to a hotspot ID as defined when the hotspots are created with the QuickTime VR authoring tools.

selection

[VR] A string corresponding to the ID of the user-selected hotspot or nil if none is selected.

action

Method to invoke when the QuickTime object is clicked. The selection parameter then contains the ID of the selected hotspot if a hotspot list has been specified, or nil otherwise.

href

An optional attribute for specifying a URL to direct the browser to when the QuickTime object is clicked and no hotspots are hit.

pageName

An optional attribute specifying the name of the WebObjects page to display when the QuickTime object is clicked and no hotspots are hit.

bgcolor

Background color for the QuickTime object. This is an optional attribute. Use bgcolor to specify the background color for any space that is not taken by the movie\x96as, for example, if you embed a 160x120 movie in a 200x120 space. Specify the color as a hex value.

target

(optional) When set, the target attribute is the name of a valid frame (including _self, _top, _parent, _blank or an explicit frame name) that will be the target of a link specified by the hotspot or href attribute.

volume

An optional attribute affecting the initial volume level. Possible values are 0 through 100. A setting of 0 effectively mutes the audio; a setting of 100 is maximum volume.

pan

[VR] This optional attribute allows you to specify the initial pan angle for a QuickTime VR movie.The range of values for a typical movie would be 0.0 to 360.0 degrees. If no value for pan is specified, the value stored in the movie is used.

tilt

[VR] This optional attribute allows you to specify the initial tilt angle for a QuickTime VR movie. The range of values for a typical movie would be -42.5 to 42.5 degrees. If no value for tilt is specified, the value stored in the movie is used.

fov

[VR] This optional attribute allows you to specify the initial field of view angle for a QuickTime VR movie.The range of values for a typical movie would be 5.0 to 85.0 degrees. If no value is specified for fov, the value stored in the panoramic movie is used.

node

[VR] This optional attribute allows you to specify the initial node for a multi-node QuickTime VR movie. If no value is specified for node , the default node and view (specified at creation time of the movie) is used.

correction

[VR] (optional) Possible values are "NONE", "PARTIAL", or "FULL" (the default). This attribute is only appropriate for QuickTime VR objects and panoramas.

cache

(optional) If cache evaluates to true (or YES), the browser will cache movies when possible just like other documents.

autoplay

(optional) When autoplay evaluates to true (or YES), causes the movie to start playing as soon as the QuickTime Plug-In estimates that it'll be able to play the entire movie without waiting for additional data. This attribute's default is specified by a user setting in the QuickTime Plug-in Preferences.

hidden

This optional attribute controls the visibility of the movie. By default the value is true (or YES); if you set it to false (or NO) the movie won't be visible on the page. This option is not appropriate for QuickTime VR Objects or Panoramas. You can use hidden to hide a sound-only movie.

playEveryFrame

When this optional attribute evaluates to true (or YES) the QuickTime plug-in plays every frame, even if it is necessary to play at a slower rate to do so. This attribute is particularly useful to play simple animations, and is appropriate for QuickTime movies. Note that enabling playEveryFrame will turn off any audio tracks your movie may have.

controller

This optional attribute sets the visibility of the movie controller (with QTVR 2.1, you can have a controller on VR Panarama or Object Movies). If you don't specify controller, the default is true (or YES) for QuickTime movies. For compatibility with existing web pages, the default is false (or NO) for QuickTime VR movies.

prefixHost

This attribute should be used to fix a bug with the QuickTime 2.x plug-in on Windows platforms. Setting prefixHost to true (or YES) will automatically add the http host name at the beginning of each dynamic URL, allowing old plug-ins to correctly handle WOQuickTime component. The default is false (or NO)
