ONLYOFFICE Docs 7.3 for developers: API & Doc Builder updates

Along with the release of the new features in version 7.3, we updated API for the editors, plugins, and Document Builder. Check all the details below.

Enhanced WOPI support

From now on, you are able to work with the binary formats such as doc, ppt, and xls within WOPI integrations. We implemented the corresponding scheme which includes the convert action in the WOPI discovery. It converts binary files into docx, pptx, and xlsx for further editing.

Besides, we added the WOPI Conversion API for easier work with different office file formats.

<form action="https://documentserver/cool/convert-to/docx" enctype="multipart/form-data" method="post">     
File: <input type="file" name="data"><br/>     
<input type="submit" value="Convert to DOCX">
</form>

Further enhancements here comprise:

• UserCanNotWriteRelative property in the CheckFileInfo WOPI operation which specifies if a user has permissions to create new files on the WOPI server or not;
• PutRelativeFile WOPI operation which creates a new file on the host based on the current file.

Inserting external data in spreadsheets

The newly added document.referenceData parameter defines an object that is generated by the integrator to uniquely identify a file in its system.

Together with the implemented setReferenceData method and onRequestReferenceData event, it is now possible to refresh data using a link to a file — when a user is trying to update values inserted from the external file by clicking the corresponding button in the External links dialog box.

var onRequestReferenceData = function () {
var referenceData =  event.data.referenceData;
var path = event.data.path;
   ...
docEditor.setReferenceData({
 "fileType": "xlsx",
 "path": "sample.xlsx",
 "referenceData": {
"fileKey": "BCFA2CED",
"instanceId": "https://example.com"
 },
 "url": "https://example.com/url-to-example-document.xlsx"
 });
};
var docEditor = new DocsAPI.DocEditor("placeholder", {
"events": {
"onRequestReferenceData": onRequestReferenceData, 
 ...
    },
 ...
});

Interface customization

Users of ONLYOFFICE Docs Developer Edition with the extended license get new options for customizing the frontend of the editors via the config file:

• adjusting the font of the interface elements such as buttons, tabs, etc.;
• defining the initial value of the right/left panel visibility – displayed or hidden.

API updates for plugins and macros

• Sign type in the initDataType config parameter.
• GetVBAMacros method which returns all VBA macros from the document.
• OnDropEvent method which implements the external drag&drop emulation.
• Spreadsheet Api and Presentation Api methods available for the window.Asc.plugin.executeMethod.

Check this code example for the OnDropEvent method:

window.Asc.plugin.executeMethod("OnDropEvent", [{
  type: "ondrop",
  x : pos.x,
  y : pos.y,
  text : "test text",
  html : "test html"
}]);
