Handsontable's unique text editor feature is encountering a tricky issue with copying and pasting

In my table, there are two columns: name and code. I have developed a simple custom editor for the code column, where the user can double click on a cell to open a custom dialog with a code editor. You can view a simplified example of this functionality here.

However, I am facing an issue with the copy/paste functionality. After editing the code in the cell using my custom editor and saving it, the value is not copied when I try to use Ctrl+C to copy it.

The question is: Is this a bug in Handsontable or did I miss something while implementing the custom editor? How should I modify my custom editor to ensure that the copy-paste feature works correctly?

Here is the code for the editor:

// Insert code here...

System Specifications: Angular version: 1.6.1 Handsontable version: 0.31.2 Chrome version: Version 58.0.3029.81

Answer №1

I recently raised an issue on the handsontable github repository and was fortunate to receive a helpful response there. You can view the issue by following this link: here

Resolution: Following the suggestion of a member from the handsontable team, I included the code this.instance.deselectCell(); before opening my dialog. However, a slight issue arose - when I pressed Enter in my code editor dialog, instead of inserting a new line, the next cell in handsontable was being selected. To remedy this, I utilized a setTimeout() function which resolved the problem.

You can access a live example on Plunker through this link: here

The effective code snippet is as follows:

ScriptEditor.prototype.open = function () {

    var self = this;

    setTimeout(function () {
        self.instance.deselectCell();
    });

    var value = self.instance.getDataAtCell(self.row, self.col);
    var decodedCode = decodeURI(value);

    var success = function (resultCode) {
        var encodedCode = encodeURI(resultCode);
        self.instance.setDataAtCell(self.row, self.col, encodedCode, 'edit');
        self.instance.selectCell(self.row, self.col);
    };

    openEditor(decodedCode)
        .then(success);

};
