How to tell if column resize is done manually vs. automatically with onColumnResized()?

Question

Before ag-grid v11.0, sizeColumnsToFit() fired with an event that did not pass the parameter 'finished=true'. When a user manually resized a column, the event would pass 'finished=true' once the resize drag was complete. This allowed me to distinguish between a manual and automatic column resize.

As of ag-grid v11.0, sizeColumnsToFit() now fires an event with parameter 'finished=true'. Is there any way to distinguish between this automatic resize and a manual user resize?

Answer 1

The ColumnEvent, from which the ColumnResizedEvent is derived has a "source" property that reads "sizeColumnsToFit" or "uiColumnDragged" and even "autosizeColumns" when a you double click the partition.

You should be able to use the source to determine how the event was fired.

myEventHandler(ev: ColumnResizedEvent) {
  if (ev.source === 'sizeColumnsToFit') {
    do.this;
  } else {
    do.that;
  }
}
