drag

I've recently dropped use of Graphael and and extensions package Ico . I think it's still a great library, it just needs better documentation and a proper API before it can be widely adopted. I've converted the areas with charting to use Google Charts and can't seem to find a way to do one particular feature I used graphael for: drag support. One of my line charts needs to be editable, meaning that individual dots on the line can be dragged up and down to adjust value. I've been trying to find an event or a way to attach an event in the API without much success. Has anyone managed to do

If you drag and release quickly from the horizontal menu, the menu will auto slide for a distance. It seems to slide more the faster you drag and release. Source -> appear.dk How do i achieve this effect? Has it got to do with some complex formulaes? This technique is called kinetic scrolling (you simulate kinetic energy). Since the dawn of the iphone this technique has been hyped, though it can be used on mobile devices with great benefit, I would refrain from using it inside a website (like all other sorts of scrolling) However, here's an easy to use jquery plugin: Here you go Overscroll

Im struggling with seemingly a simple javascript exercise, writing a vanilla drag and drop. I think Im making a mistake with my 'addeventlisteners', here is the code: var ele = document.getElementsByClassName ("target")[0]; var stateMouseDown = false; //ele.onmousedown = eleMouseDown; ele.addEventListener ("onmousedown" , eleMouseDown , false); function eleMouseDown () { stateMouseDown = true; document.addEventListener ("onmousemove" , eleMouseMove , false); } function eleMouseMove (ev) { do { var pX = ev.pageX; var pY = ev.pageY; ele.style.left = pX + "px"; ele.style.top = pY + "px"; document

I need to slide a uibutton up and down the screen (Y only). It needs to be confined to an area. I want to be able to click on it and drag or flick it, just like a uiScrollView. The reason it is different to a uiScrollView is that you have to start on the button, as opposed to anywhere inside a uiScrollView! You can move a view by using touch moved event. There is a sample tutorial MoveMe by Apple which drags a view and after releasing the touch animate the view. Check specially the touch events (touchesBegan, touchesMoved, touchesEnded) in MoveMeView.m to get the idea how they have moved

I want to implement a movable imageView when it is drag. The dragging is working perfectly alright. But when i drag to the end , the imageView goes out of the screen. How can i make the movable of the imageview only inside the screen ? This is my OnTouch listerner : public boolean onTouch(View view, MotionEvent event) { switch (event.getActionMasked()) { case MotionEvent.ACTION_DOWN: dX = view.getX() - event.getRawX(); dY = view.getY() - event.getRawY(); lastAction = MotionEvent.ACTION_DOWN; break; case MotionEvent.ACTION_MOVE: view.setY(event.getRawY() + dY); view.setX(event.getRawX() + dX);

I want to draw rectangle based on mousedrag event. if user dragging the mouse, then the rectangle on the applet should increase or decrease basing on current mouse coordinates. i have the following code. in the following code i am using SelectionArea class which extends a canvas on which i am performing drawing operation. i am using image variable in this class for double buffering to reduce flickering and to save the applet's previous state(i.e drawing content of applet) but the code is working fine if i draw first rectangle. if i start to draw second rectangle the previously drawn rectangle

// my code that calls upon n images in a directory to be placed on the JPanel public void imageAdder(int n, String name){ BufferedImage myPic = null; for (int i = 0; i <= n; i++){ try { myPic = ImageIO.read(new File("Images/" + name + i + ".jpg")); } catch (Exception e){ System.out.println("no file man cmon"); } JLabel picLabel = new JLabel(new ImageIcon(myPic)); // picLabel.setBounds(mouseX, mouseY, 100, 50); // picLabel.addMouseMotionListener(this); // picLabel.addMouseListener(this); canvas.add(picLabel); }} I read about the class DragSource and how there's a method that drags things of
