Hello,
I have seen a few posts about this with no reasonable solution it would
seem. What I want to do is handle the click event on a treemap Node and if
the selected Node is the header call the goUpAndDraw() method.
First of all it is not simple to find which Node is a header. Then once I
do call goUpAndDraw(); nothing happens. It would appear that the 'select'
event is then further being handled by google. Does anyone know how to get
around this, for instance in c# one could declare that they have handled
the event by "event.handled = true". If I call goUpAndDraw() outside of the
select event it works fine. A hack is to use setInterval to rollup 1ms
later. Any help would be appreciated, also is there any simple way to see
if the selected node is the header?
This is my select and rollup event handlers the problem with this code is
once i reach a final level node the level gets set incorrectly.
var level = 0;
function selectHandler() {
var itemLevel = chart.getSelection()[0].row;
console.log(itemLevel);
if (itemLevel != level) {
level = itemLevel;
} else {
console.log("HIT HEADER");
goUpTimer = setInterval(goUpAndDraw, 1);
//chart.goUpAndDraw();
}
}
function rollUp() {
window.clearInterval(goUpTimer);
var itemLevel = chart.getSelection()[0].row;
level = itemLevel;
console.log("SETTING LEVEL TO " + level);
}
