问题 I have a function that display the buffered image. I want mouse listener and key listener to be implemented in JLabel which loads the image.

Also i noticed that KeyListener and MouseListener works in Constructor but not in other methods. is it true

问题 WRT building a Firefox Add-on. Is it possible to get the element under the mouse via some XPCOM or javascript method? (non-js-ctypes please as that requires OS specificity) I want to detect what is under the mouse when user presses Ctrl + Shift + M . Right now I'm adding a mouseover listener to the document when the user presses this hotkey, so I can get the element under the mouse when he moves it, but not the element that was under the mouse exactly when he pressed the hotkey combination.

问题 This question already has answers here : Find what javascript changes the DOM? (2 answers) Closed 6 years ago . I'm trying to look at the html produced by a jQuery tooltip plugin (qTip v1). The tooltip only appears when I hover over the element with my mouse pointer. Normally I'd just inspect the html or dig deeper with Chrome's developer console, but as soon as I do that the tooltip disappears because the mouseover event ends. The tooltip's position is outside the normal flow of the document

I don't know where to look anymore... private Point _panStartingPoint = Point.Empty; private bool _panIsActive; private void CurveBox_MouseDown(object sender, MouseEventArgs e) { if (e

问题 I have one outer panel, in the outer panel I have another jPanel placed on it. if i do a right click on the inner panel, outer panel's right click action should happen. if i do left click on the inner panel, its own inner panel's click action should happen. Is it possible to pass click event from one panel to another panel? 回答1: There are a number issues you need to resolve for this to work. The first is understanding that a mouse event is contextual to the component that created it, in

问题 I am working on a JavaFX 2.2 project and i want to set custom handling of the mouse (double) click event on a TreeItem. Using treeview.setOnMouseClicked i fire my code without errors but the problem is that the TreeItem, on every mouse double click, it toggles between expanded and collapsed. I suppose that this is the default behavior, but how i disable it?? 回答1: I had the same issue and solved it in time using EventDispatcher . class TreeMouseEventDispatcher implements EventDispatcher {

问题 Simplified Problem: Make one Node "A" that is on top of another Node "B" to be half transparent to MouseEvents, so the Events will reach the underlying Node "B". Both Nodes are of equal size but Node "A" has a half transparent background image so one half of Node "B" is visible. Real Problem: I have a menu of tabs. Each tab can be dragged to expand the corresponding menu layer. Therefore each tab layer is a Pane with a partially transparent background (basically a polygon) of which the

问题 I have a very simple C# console application that displays some text and loops waiting for input until the escape key is pressed or the timeout period is served. using System; using System.Collections.Generic; using System.Diagnostics; using System.Linq; using System.Text; using System.Threading; namespace SampleApp { public static class Program { public static void Main (string [] args) { var key = new ConsoleKeyInfo(); var watch = Stopwatch.StartNew(); var timeout = TimeSpan.FromSeconds(5);
