GUI composer API reference

Simon Coulter
Prodigy 200 points

Is there any comprehensive reference or guide for the APIs used in the GUI composer? Code such as: 

var fileInfo = getFileInfo();
var options = getOptions();
var callback = function ( errorInfo) 
{
	showError( errorInfo);
};
TI.File.save( graph_data, fileInfo, options, callback);

particularly the last line, isnt exaplained anywhere, and i cant find a reference to the TI api anywhere. Does such a thing exist?

Failing that, is there a version of TI.file.save that appends to a file rather than creating a new one?

    Hello Simon,

     

    The APIs you are asking are documented in the JavaScript library that defines them:

    $(YOUR_GUI_COMPOSER_INSTALL)\eclipse\plugins\davinci.gc_1_5\WebContent\gc\backplane\guiComposer.js.

    Toward the end of the file: line 1547 to 1780.

     

    The answer to your second question you will probably find in the documentation of TI.file.save function:

                    …

                                                     * @param options- see options description in File.

                                                     *                                                            append : true - to add to the end of the file instead of the beginning.

                                                     *                                                            addCRBefore : true - if CR should be inserted before data.

                                                     *                                                            addCRAfter : true - if CR should be inserted after data.

                    …

     

    There are two examples of how to user the file operations, you may want to look at.

    1. Demonstrates app with File Open/Save/Save As. functionality: http://processors.wiki.ti.com/index.php/GUI_Composer/FileOperations
    2. Demonstrates logging of graph data to a file is: http://processors.wiki.ti.com/index.php/GUI_Composer/Logging_Graph_Data

     

    You can see in the second example uses “append” option.

     

    Regards
