Locks the object(s) currently being edited (selected).
AnnAutomation.prototype.lock = function()
lock(): void;
Use the CanLock property to determine whether you can currently call this method.
For more information, refer to Implementing Annotation Security.
The following example will show how to lock and unlock an object, prompting the user for a password.
example: function SiteLibrary_DefaultPage$example() {
var _this = this;
// first add a new object to the automation
var rectObj = new lt.Annotations.Core.AnnRectangleObject();
rectObj.set_rect(lt.LeadRectD.create(100, 100, 800, 800));
rectObj.set_stroke(lt.Annotations.Core.AnnStroke.create(
lt.Annotations.Core.AnnSolidColorBrush.create("blue"),
lt.LeadLengthD.create(1)));
rectObj.set_fill(lt.Annotations.Core.AnnSolidColorBrush.create("yellow"));
this._automation.get_container().get_children().add(rectObj);
this._automation.invalidate(lt.LeadRectD.get_empty());
// make sure no objects are selected in the automation
this._automation.selectObject(null);
var myPassword = "secret";
// Hook to the lock and unlock events
var lockObject = function(sender, e) {
// e is of type AnnLockObjectEventArgs
alert("Lock it, sending password = " + myPassword);
e.set_password(myPassword);
};
var unlockObject = function(sender, e) {
// e is of type AnnLockObjectEventArgs
alert("Unlock it, sending password = " + myPassword);
e.set_password(myPassword);
};
this._automation.add_lockObject(lockObject);
this._automation.add_unlockObject(unlockObject);
// see if we can lock or unlock the object (this should show a message informing you that no objects are currently selected (bring edited)
this.lockUnlock(this._automation);
// select (edit) the object we have just added
this._automation.selectObject(rectObj);
// see if we can lock or unlock the object (should show the password dialog to lock the object)
this.lockUnlock(this._automation);
// see if we can lock or unlock the object (should show the password dialog to unlock the object)
this.lockUnlock(this._automation);
this._automation.remove_lockObject(lockObject);
this._automation.remove_unlockObject(unlockObject);
},
lockUnlock: function SiteLibrary_DefaultPage$lockUnlock(automation) {
// first, check if we can lock the object
if(automation.get_canLock()) {
// lock this object
automation.lock();
}
else if(automation.get_canUnlock()) {
// unlock this object
automation.unlock();
}
else {
alert("Cannot lock or unlock because no object is currently being edited (selected)");
}
},
