70001897 Override the draw of the default axis cursor

Summary

Override the draw of the default axis cursor

Solution

In version 8007.0.1 a new event vdDrawCursor of vdcanvas control added
Represents a user define function of type that will be called during the default cursor (cross) drawn.
The ovverride function returns true in order to cancel the default draw of the cursor
Example: display world coordinates of the current cursor position

vdcanvas.vdDrawCursor = _vdDrawCursor;
function _vdDrawCursor(action) {
var ptcur = action.CurrentPoint; //get the current mouse location in world Coordinate system
var txt = vdcanvas.AddText("", 1, ptcur, vdConst.VdConstHorJust_VdTextHorLeft, vdConst.VdConstVerJust_VdTextVerTop, 0.0, false, {});
txt.BackGroundMask = true;
txt.BackGroundMaskColor = vdConst.colorFromString("0,0,127,127");
txt.BackgroundMaskBorder = true;
txt.BackGroundMaskBorderColor = vdConst.colorFromString("127,127,127,255");
txt.PenColor = vdConst.colorFromString("255,255,255,255");
var pixelsize = vdcanvas.GetPixelSize();
txt.InsertionPoint = vdcanvas.WorldToView(ptcur);
txt.Height = pixelsize * 10;
txt.TextString = "x=" + ptcur[0].toFixed(2) + "\ny=" + ptcur[1].toFixed(2) + "\nz=" + ptcur[2].toFixed(2);
vdcanvas.UpdateFig(txt);
vdcanvas.ActiveRender().PushToViewMatrix();
vdcanvas.DrawEntity(txt);
vdcanvas.ActiveRender().PopMatrix();
