UniDBGrid Get Cell By X Y Position

[SilvaM]

Hi!

 

I need to select a cell (or a row) in a UniDBGrid using XY Position. 

 

How could I implement something like this:

 

Ext.override(Ext.grid.GridView, { 

    /** 
     * Returns a cell row, col, and element, by the xy coodinates 
     *  
     * @param {Integer} x 
     * @param {Integer} y 
     * @returns {Array} [row, col, el] 
     */ 
    getCellByXY: function(x, y) { 
        var view = this, 
            rows = view.getRows(); 
         
        //loop rows 
        for (var i = 0; i < rows.length; i++) { 
            var j = 0, cell; 
            //loop cells in row 
            while (cell = view.getCell(i, j)) { 
                var cellEl = Ext.get(cell); 
                 
                if (cellEl.getTop() <= y && cellEl.getBottom() >= y) { 
                    if (cellEl.getLeft() <= x && cellEl.getRight() >= x) { 
                        return [i, j, cell];  
                    } 
                } else { 
                    //prevent useless cell loops in wrong row 
                    break; 
                } 
                 
                j++; 
            } 
        } 
         
    } 
});

Hi SilvaM.

XY - mouse coordinates?

Best regards.

Yes, I need to select the row in the XY mouse coordinates.

Thank you.

In web it is better to avoid absolute positioning.

What do you want to achieve? There may be a better way.

I'm having a problem with double click on iPAD. I just think to use onmousedown event by myself (and disable onclick) to try to solve it.

Hi SilvaM.

 

If I understand correctly, try:

 

UniDBGrid1 -> ...

function itemmouseenter(sender, record, item, index, e, eOpts)
{  
  if (sender.getSelectionModel()) {
    sender.getSelectionModel().select(index)
  }; 
}

Works correctly when:

 

1. Grouping.Enabled := False;

2. Options, dgRowSelect := True;

 

Best regards.
