mouseevent

问题 I have an strange issue. I have a picture box double click event as well as single click event. The problem is even I double click the control, single click event is raised [If I disable single click event, double click event is working]. This problem has been discussed here , but nobody gave a right answer 回答1: Have a derived Picturebox control class class PictureBoxCtrl:System.Windows.Forms.PictureBox { // Note that the DoubleClickTime property gets // the maximum number of milliseconds

问题 Is it possible to place a child component inside a JButton and make it transparent to a subset of mouse events so that: The child component receives MouseMotionEvent s (so it can respond by modifying a displayed image) Clicking still depresses the JButton "behind" the child component If you add the child component to the button but make no other changes, clicking in the area occupied by the child does not activate the button. I know this can be achieved by creating a new class that extends

问题 I tried implementing the second answer posted in this post here. I have the desire as the person asking the question however my mouseDown is not working/registering. Here is what I have. AppDelegate.h AppDelegate.m MouseDownTextField.h MouseDownTextField.m and there relavent content: AppDelegate.h #import <Cocoa/Cocoa.h> #import "MouseDownTextField.h" @interface AppDelegate : NSObject <MouseDownTextFieldDelegate> { NSWindow *window; IBOutlet NSMenu *statusMenu; NSStatusItem *statusItem;

问题 I am stuck at mousewheel event that just doesn't fire. I use swt_awt bridge, so I am able to use swing component in my RCP application. I tested everything I was able to find, but with no success. Because my application is awfully complex, I created a simplified version of my problem, which should also help you to orientate if you would like to help me. Now this simplified problem is, that I want my textarea (or scrollpane) to catch mousewheel events. But these events are lost. import java

问题 How can I bind mutiple events to the same function. I want click and touchstart to do the same. And then I want a second function for mouseover. I would like to use this kind of setup: $(document).on({ click: function (event) { // I want this: click, touchstart: function (event) { event.preventDefault(); // do something }, mouseover: function (event) { event.preventDefault(); // do something } }, '.link'); 回答1: You can combine the events in one .on() with space: $(document).on('click

问题 This is a rephrased question from here. After some testing I isolated the problem, but have no clue on fixing it. No need to read the previous question, this is the simplified code: THE PROBLEM -> trigger('click') executes, but the event doesn't trigger when inside looped (intervaled) function $(document.ready(function(){ var checkForConfirmation = function(){ clearInterval(checkInterval); $("#anchorLink").trigger('click'); } var checkInterval = setInterval(function(){checkForConfirmation()},

问题 I'm writing an essentially character-based program, but running in an xterm, and want to use mouse scroll-wheel-up/down and left-clicks as synonyms for keyboard arrow-up/down and return, just for a little extra user convenience. I've got a select() with all the input fdset's working fine, and am asynchronously capturing the raw input fine (seems so, anyway). But I'm having a little trouble unambiguously interpreting the type,code,value members from the input_event struct. /usr/include/linux

问题 I am working on a project within Python that is to determine the multi-tasking efficiency of a person. Part of the project is to have a user respond to an event on screen using the mouse. I have decided to have the user click within a ball. However I am having issues with my code on verifying that the mouse cursor is actually within the confines of the circle. The code for the methods in question are below. Radius of the circle is 10. #boolean method to determine if the cursor is within the

问题 I have a JPanel with multiple components in it - like a few JLabels , JTextBoxes , JComboBoxes , JCheckBoxes etc. I want to display a pop up help window if the user hovers over these components for say 3 secs. So far I added a MouseListener to one of my Components and it does display the required pop up and help. However I can't achieve it after 3 sec delay. As soon as the user moves the mouse to through that area of the component the pop up displays. This is very annoying as the components
