DecSoft App Builder

Audio player

The Audio player control allows to reproduce audio media files into your developed apps. This control offer several properties and methods in order to set the behaviour and made some related control task.

There is a AudioPlayer sample app included with the installation of DecSoft App Builder. Take a look to see this control in action!

Audio player CSS rules

This control has a default style, and, some control JavaScript properties (see below), can also changes the control style, not to mention the Classes property, that you can use to establish one or more CSS classes to be applied to the control.

In addition to that style, you can also set custom CSS rules for the control by using the IDE controls style inspector. If this is not enough, you can include any number of CSS stylesheets in the app by using the app files manager.

If you want to use CSS stylesheets, you need to know how to refer to the control, so take a look at the Runtime selectors help topic.

Audio player designtime properties

The Audio player control put at your disposition the below designtime properties or variables. Designtime means here that these properties are only available in designtime and not in runtime.

Audio player runtime properties

The Audio player control put at your disposition the below runtime properties or variables. You can set almost all these variables in designtime, and, they are also available to be use when the app is running. Note that we named here these variables in a capitalized way, because is like you can see it in the designtime control's inspector, however, at runtime we use the lower camel case way.

Audio player methods

The Audio player control put at your disposition the below methods. You can use these methods in runtime in order to perform various control related tasks.

Audio player events

The Audio player control put at your disposition the below events handlers:

Audio player designtime properties

Audio player Top property

Designtime. Integer variable. The Top property stores the top position of the control in pixels. The pixels are relative to the app view, dialog or frame, and, is used "as is" if the app have the "Scale" app option is set to "false". Remember that this control property is only for designtime and is not available in runtime.

Audio player Left property

Designtime. Integer variable. The Left property stores the left position of the control in pixels. The pixels are relative to the app view, dialog or frame, and, is used "as is" if the app have the "Scale" app option is set to "false". Remember that this control property is only for designtime and is not available in runtime.

Audio player Width property

Designtime. Integer variable. The Width property stores the width of the control in pixels. The pixels are relative to the app view, dialog or frame, and, is used "as is" if the app have the "Scale" app option is set to "false". Remember that this control property is only for designtime and is not available in runtime.

Audio player Height property

Designtime. Integer variable. The Height property stores the height of the control in pixels. The pixels are relative to the app view, dialog or frame, and, is used "as is" if the app have the "Scale" app option is set to "false". Remember that this control property is only for designtime and is not available in runtime.

Audio player Locked property

Designtime. Boolean variable. The Locked property determines if the control can be moved or resized in app view designer or not. Set a "false" value mean the control can be moved and resized. Set a "true" value (by default) mean the control cannot be moved nor resized. Remember that this control property is only for designtime and is not available in runtime.

Audio player runtime properties

Audio player Name property

Runtime. String variable. The Name control property stores the name of the Audio player control as you set in designtime. The Name property value must be unique for the same app view, dialog or frame, that is, it's possible to have more than one "yourControlName" in the app, if that controls resides in different app views, dialogs or frames. Note that you must consider this variable as read only: change the name of a control in runtime can cause unexpected results.

Audio player Event property

Runtime. Mixed variable. The Event control property stores the "event" variable received in all the control events. This variable can contain the target (HTML element of the control) that fire the event and more useful stuff.

Audio player AutoPlay property

Runtime. Boolean variable. The AutoPlay control property can be set to "true" (it's "false" by default) at designtime in order to start the reproduction of the audio when the app view is show. Note, however, that some platforms can refuse to play a audio without the user intervention. Some platforms allows autoplayed audios only if muted. You can mute the audio using the Muted property.

Audio player Controls property

Runtime. Boolean variable. The Controls control property determines if the default player controls (play, stop buttons, seek bar, etc.) must be shown or not. This property is "true" by default but you can set to "false" in order to hide the default player controls. Remember that it's possible to control the player reproduction using the available control methods.

Audio player Loop property

Runtime. Boolean variable. The Loop control property determines if the media player must start to reproduce the media file again and again after their complete reproduction. This property is "false" by default but you can set to "true" in order to loop the player reproduction.

Audio player Muted property

Runtime. Boolean variable. The Muted control property determine if the reproduction sound must be muted. This variable is "false" by default but you can set to "true" to mute the sound. This property can be useful to use with the AutoPlay property for platforms and browsers that allows autoplayed audio, but only if they are muted.

Audio player Sources property

Runtime. Array of objects variable. The Sources control property allows to specify more than one differents audio media source files to be used. The browser or platform can then pick one of then in order to be reproduced.

You can set the Sources property at designtime using the Media sources dialog, or, can set it un runtime using the appendSource() method.

Note that, after the Sources property has been filled we cannot change the Audio player source (to be reproduced) using this property: when we need this we must manually set the Source property or by using the setSource() method.

Audio player Source property

Runtime. Object variable. The Source control property allows to set the current media file source to be reproduced in the Audio player. We can set this property manually or by using the setSource() method.

A source object is composed with the below properties:

Name Type Description

type String The media file type / codec to be used. This property is optional, and, if not provided, the browser or platform try to automatically detect the media type and codec to be use.

Audio player Volume property

Runtime. Number variable. The Volume control property stores the current Audio player sound volume, which can be a value between 0 and 1. You can check this property to know the current volume level. To set the Audio player sound volume, however, you must use the setVolume() method.

Audio player Duration property

Runtime. Number variable. The Duration control property stores the length of the media file in seconds. This property is available after the DurationChange event has been fired.

Audio player CurrentTime property

Runtime. Number variable. The CurrentTime control property stores the current reproduction position in seconds. This property is available after the TimeUpdate event has been fired.
