After 35 selecting an item, you can use this plugin to quickly review its supported interfaces, to retrieve 36 each interface's information, and to manipulate the item through all the interface’s methods. 37 </p> 38 39 <figure> 40 <title>Examining a Menu with the Interface Viewer Plugin</title> 41 <desc> 42 Given a selected item in the Application Tree View, all of its AT-SPI interfaces will be shown as sensitive 43 in the Interface Viewer Plugin.

After that, all AT-SPI interfaces covered by the plugin will be listed in the 58 plugin's panel. The interfaces implemented by the selected item will be sensitive, so you can click each one of 59 them to either retrieve their provided information or to interact with available methods. The following interfaces 60 can be explored in <app>Accerciser</app>, assuming the selected item implements them: 61 </p> 62 <list> 63 <item> 64 <p> 65 Accessible - This interface shows the selected item's child count (number of child widgets), description, states, 66 relations, and attributes. 67 </p> 68 </item> 69 <item> 70 <p> 71 Action - This interface shows all the actions that can be performed by the selected item. For each interface, 72 you will see its name, such as "press" or "click", followed by a description and a key binding, if there are 73 any. If you select an action, a "Perform action" button will become sensitive. Press this button to see the 74 item performing the selected action. 75 </p> 76 </item> 77 <item> 78 <p> 79 Application - This interface can be implemented by items with role "application". It is worth to point out that 80 items with role "application" not necessarily implement this interface. If the selected item implements it, the interface 81 will show its ID and, if there are any, its toolkit and version. 82 </p> 83 </item> 84 <item> 85 <p> 86 Component - This interface shows the selected item's absolute position (with respect to the desktop coordinate system), relative position (with respect to the window coordinate system), size, layer type, MDI-Z-order (a short integer indicating the 87 stacking order of the component in the MDI layer), and alpha (if alpha blending is used). 88 </p> 89 </item> 90 <item> 91 <p> 92 Document - This interface shows the selected item's document attributes and locale description, if there is one. 93 </p> 94 </item> 95 <item> 96 <p> 97 Hypertext - This interface shows a list with all the selected item's hypertext hyperlinks. For each hyperlink, the interface 98 provides its name, URI, start (the index in the hypertext at which the hyperlink begins) and end (the index in the hypertext 99 at which this hyperlink ends). 100 </p> 101 </item> 102 <item> 103 <p> 104 Image - This interface shows the selected item's description (or "no description" if unspecified), size, position 105 (with respect to the desktop coordinate system), and locale, if there is one. 106 </p> 107 </item> 108 <item> 109 <p> 110 Selection - This interface shows all selectable child items of the selected item. If the selected item is a menu bar 111 with options "File", "Edit", "View", and "Help", and all of them are selectable, then they will be listed in this 112 interface. If you click a listed option - "File", for example - and want to clear it, just press the "Clear" button 113 below the list. 114 </p> 115 </item> 116 <item> 117 <p> 118 Streamable Content - This interface shows the selected item's content types and their corresponding URIs. 119 </p> 120 </item> 121 <item> 122 <p> 123 Table - This interface shows the selected item's caption and summary, rows (number of rows), columns (number of columns), 124 selected rows (number of selected rows), and selected columns (number of selected columns). For a selected cell, the 125 interface shows its row's and column's header and extents. 126 </p> 127 </item> 128 <item> 129 <p> 130 Text - This interface shows the selected item's text content, that can be editable, and its attributes. The basic 131 attributes are offset (the number of characters the text has) and justification. To see possible CSS attributes, 132 click the "Include defaults" check box. 133 </p> 134 </item> 135 <item> 136 <p> 137 Value - This interface shows the selected item's current value, minimum allowed value, maximum allowed value, and 138 the minimum increment by which the value may be changed (or zero if this value cannot be determined). The current 139 value can be manually changed via a spin button. 140 </p> 141 </item> 142 </list> 143 </section> 144</page> 145
