I have nested vertices and I'm looking to directly select the child vertex with just one click.
Currently, when I click on a child vertex, it first selects the parent vertex instead.
It's selecting the parent vertex initially:
To select the child vertex, I need to double-click on it.
The child vertex gets selected only after double-clicking:
Is there a way for me to single-click and select the child vertex without having to go through the parent first?
The issue has been resolved by customizing the getInitialCellForEvent function.
mxGraphHandler.prototype.getInitialCellForEvent = function(me)
{
var state = me.getState();
return (state != null) ? state.cell : null;
};
I made modifications to the original code by eliminating a section that retrieves the topmost cell.
/**
* Function: getInitialCellForEvent
*
* Custom implementation to determine the initial cell for the event. This method now returns
* the topmost selected or unselected cell.
*/
mxGraphHandler.prototype.getInitialCellForEvent = function(me)
{
var state = me.getState();
if ((!this.graph.isToggleEvent(me.getEvent()) || !mxEvent.isAltDown(me.getEvent())) &&
state != null && !this.graph.isCellSelected(state.cell))
{
var model = this.graph.model;
var next = this.graph.view.getState(model.getParent(state.cell));
while (next != null && !this.graph.isCellSelected(next.cell) &&
(model.isVertex(next.cell) || model.isEdge(next.cell)) &&
this.isPropagateSelectionCell(state.cell, true, me))
{
state = next;
next = this.graph.view.getState(this.graph.getModel().getParent(state.cell));
}
}
return (state != null) ? state.cell : null;
};
