d3.js - Javascript d3: Is there a way to progammatically stop dragging an item? -

-

When I click and drag an item, is there a way to stop it from dragging it tightly without leaving the mouse button? For example, if I drag an item into a certain limit box, can I drop the item to drag it?

I have suppressed a drag example from another user; Click to create a circle, then drag it to the blue box, look for it to work.

Here the concept is called X & amp; When an object is being dragged, then it is synced in d3.event , then trigger one of the two ways shown in the bottom as 'stop' event. The drawback is that Until drag event gets a mouseup, it throws an error, while the mouse is still being paused 

  // drag lewier var drag = D3. Beavier Define drag (.on) ("drag", drumvov); Function dragmove (d) {// if event.x exceeds one limit, trigger "dragend" (d3.event.x> 200) {// using D3 drag.dragend (); // or using jquery drag.trigger ("dragend"); } Var x = d3.event.x; Var y = d 3.event.y; D3.select (this) .attr ("conversion", "translation (" + + "," + y + ")"); }   
 The range here is based on a variable - x position, but can be expanded on the basis of a size surface area.  
 The drag is being used for this event as a namespace, for an event for which D3 creates a dispatcher object (see D3 library code). It can be called by event name (for example)  
  drag.on ("eventName", functionToDo) drag.eventName ();   
 Or if you want to use the  JQuery , it can be used by using a trigger:  
  Drag.trigger ("dragend")   
 Attaching a mouseover event to 'border box' does not work because the object will be dragged between the mouse and the box. Perhaps there is also an alternative solution I have included another small red box (open the console to do this  not  to work)

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
