After the latest update of bryntum4, the tooltip does not work as in previous versions. In the following example, https://www.bryntum.com/examples/scheduler/tooltips/, I added the following tooltip widget,

var _commonTooltip = function(type, id, selector, url) {
  var obj   = {},
      json  = {},
      tip   = new Tooltip({
        id:                   id,
        forSelector:          selector,
        hideOnDelegateChange: true,
        showOnHover:          true,
        anchorToTarget:       false,
        hideDelay:            50, // The time (in milliseconds) for which the Tooltip remains visible when the mouse leaves the target
        listeners: {

    beforeShow: function() {

        tip.html = 'hello';


and made eventTooltip as false.

_commonTooltip('column', 'columnTooltipId', '.b-grid-cell, .b-grid-cell *');

_commonTooltip('column', 'activitiTooltip', '.b-sch-event, .b-sch-event *');

. The tooltips does not dissapear on mouseleave in version4.0.3 but the same works in version3.1.9.
Please find attached screenshot fir version4.0.3 where tooltip does not disappear.

Hi janan,

Thanks for the report. I was able to reproduce this issue. Looks like hideOnDelegateChange : true makes some problems. We will fix it. To track the status, please use this link: https://github.com/bryntum/support/issues/1910

All best,

Hello @janan,

The issue you reported is not a bug. The tooltip stays because it is still over the cell. The event is in a cell, so it is over both targets. You can modify the selectors as following, for example:

commonTooltip('.b-sch-event-wrap, .b-sch-event-wrap *');
commonTooltip('.b-grid-row :not(.b-sch-event-wrap), .b-grid-row :not(.b-sch-event-wrap) *');

Or use our features, which provide you access to the eventTooltip and scheduleTooltip.

Best regards,
