findByPixels returns cell with incorrect date

Asked by Ruud

Hi,

i have configured infinity scrolling, onIncludeTimeCell(days start at 12:00), and zoom levels.
Now i am using the onGridMouseDown event and i feed the args.originalEvent.x and y into findByPixels to know what cell was clicked. But the date from the cell that is returned is incorrect.
if i click on the cell from 15 jan 12:00 to 16 jan 12:00 it returns a cell with start: 2020-2-2T12 and end: 2020-2-3T12.
If i click on the cell from 15 march 12:00 to 16 march 12:00 it returns a cell with start: 2020-2-13T12 and end:2020-2-14T12.

if i click of the first cell that is shown(left top corner of the grid, second row) the timeline shows this as June15 12:00 to June 16 12:00 the cell returned by findByPixels returns start:2020-1-20T12 and end: 2020-1-21T12.

It seems findByPixels does not take the scrolling into account. Or is can't i use the onGridMouseDown args location with findByPixels.

If you need more information about my config please let me know.

And what's the use case?

The purpose of onGridMouseDown is to modify the click + shift/ctrl/meta behavior before the actual events are fired, not to handle clicks on events and cells.

Normally you wouldn't use this event at all. Instead, use onEventClick/onEventRightClick/onTimeRangeClick/onTimeRangeRightClick or active areas inserted into events/cells.

The cells.findByCells() method works with grid coordinates, not viewport coordinates. The current mouse coordinates (relative to the grid) are available using getCoords().

I was looking for a way to know what cell was clicked without it being selected. but i found a way of doing this with the onTimeRangeSelect and clearing the selection.

Thanks for the information
