I have a rectangle which I am rotating it to -45 but on drag the rotation is not applied.
Code:
function createPoly(x, y)
{
var width = 41;
var height = 41;
var centreX = width / 2;
var centreY = height / 2;
var shape = d3.select(this);
var poly = svg.append("g")
.classed("bpmnGateway", true)
.append('svg:rect')
.attr("type", "poly")
.attr("x", (x - centreX))
.attr("y", (y - centreY))
.attr("width", 41)
.attr("height", 41)
.attr("transform", "rotate(-45)")
.attr("stroke-width", "1.5px")
.attr("stroke", "#7E7E7E")
.style('cursor', 'move')
.style("fill", "#FFED6B")
.call(drag);
}
function drag()
{
if (shape.attr('type') === 'poly')
{
translate = d3.transform(shape.attr("transform")).translate;
var x = d3.event.dx + translate[0];
var y = d3.event.dy + translate[1];
shape.attr("transform", "rotate(-45)")
shape.attr("transform", "translate(" + x + "," + y + ")");
}
}
I tried with rotate option inside drag function which didn't work. How do I get it to work?
The second attr function overwrites the first. You could just do both in one eg
shape.attr("transform", "rotate(-45) translate(" + x + "," + y + ")");
or
shape.attr("transform", "translate(" + x + "," + y + ") rotate(-45)");
Depending on the order you want the transforms to be applied.
