drag

When dragging any circle in this d3 example , what prevents the circle's center from snapping to the mouse? In other words: when you initiate a circle drag by clicking somewhere near the outer edges of the circle , what in the code preserves the offset (relative to the circle's center) that's implied at drag start? I see these .attr() calls: .attr("cx", d.x = d3.event.x) .attr("cy", d.y = d3.event.y) But I expect d3.event.x (and .y ) to be the coordinates of the mouse — without accounting for the offset — and therefore I would think that the circle's center would (incorrectly, from a UX point

I am trying to use monkeyrunner to simulate complex touch events. A swipe from a to b with... device.drag((300,500),(300,650),0.5,50) works great but a complex movement from a to b to c doesn't work trying with that device.touch(100,500, 'DOWN') device.touch(300,500, 'MOVE') device.touch(300,400, 'MOVE') device.touch(300,400, 'UP') Was seaching for a solution and found this.. https://android-review.googlesource.com/#/c/50991/ Is this already implemenet in the offical android sdk? or did i have to compile it or something else and how it works? I dont really know but i think this side is the

I am in a tricky situation, hope you can help me with it. I have few views (TextViews), horizontally placed one after another in a linear layout. When I press on textview1, drag my finger to any other textview and release touch, I want to be able to get the view(textview) on which the finger was lifted. I went over the TouchListener api, it says that every event starts with a ACTION_DOWN event action. Since other textviews won't fire that event, how can I get the reference to the textViews on which I lifted my finger? I tried it even, and the action_up would fire only on the textView that

I want to be able to drag over a bunch of controls and select those of a certain type (TextBoxes). Once the dragging action has been completed, I want to display an inputbox (yes, I'll have to reference/use the VB .dll) prompting the user for the value that will be entered in each selected TextBox. Can this be done? (of course, but how?) Or is there another way to accomplish the same thing (allow the user to quickly select multiple controls and then perform an action on all of them at once)? Updated: I've got this sort of working - the "caveat" or "gotcha" being that I have to pop up a

I am writing a designer that enables the user to drag controls around the screen. What would be the best way of detecting if a control is overlapping another control while i am dragging the one control around? Should i just get the dimensions of the FrameworkElement and keep on checking the dimensions of the other elements? Thanks. Eli bitbonk The dimension (FrameworkElement.ActualWidth FrameworkElement.ActualHeight) and postion (Canvas.Top, Canvas.Bottom,Canvas.Left, Canvas.Right) of your elements would suffice if they are always rectangular. In that case you can easily calculate if two

I have a problem with my custom window (AllowTransparency, WindowStyle=None) in WPF. DragMove() method works good, but when I maximize window, or it maximizing automatically by Windows 7 Aero Snap, this method does not work at all. So I can't unsnap window with mouse drag and return it state to WindowState.Normal. Left and Right Aero Snap works good, I can snap and unsnap window without a problem. But when it maximized, nothing works except Win+Down combination. Maybe somebody knows how to solve this problem or where can I find other ways to do proper DragMove of custom window with working

I want to be able to drag a divider up and down to resize the divs above and below the divider on a fixed page height. These divs could be in a table, although they need not be. In short, I would like to be able to emulate what happens on the jsFiddle site, although I only need the vertical resize. jsFiddle have used mooTools, but I want to do it with jQuery. One important complication: I won't know the size of the div above the divider until it is actually built dynamically, so I can't just start with a set absolute positioning. What is the best way forward? I have a feeling I'll just be
