mouse

问题 I am writing an application to fully control the mouse click/movement. For instance, if I have the application running, form fully transparent, fullscreen, then if I click the mouse button, in normal case, it will bring the application in background in focus - I need to stop this from happening (i.e. clicking the button and nothing visible should happen on the screen), as I need to process all the mouse activity and send it out using this application. I need to allow 2 mouse to act

问题 I'm working on a game in Java and have the following challenge. I have 2 JPanels and need to visually drag shapes from one JPanel to another. I've got this working using the GlassPane from the JFrame . When I press the mouse to drag a shape, the GlassPane activates and transfers the shape to the glassPane. Because of this you need to transfer the mousePressed state from the JPanels mouseAdapter to the glassPanes mouseAdapter . I solved this by using the Robot Class which simulates another

问题 I am trying to get the coordinates of a click with the mouse in C# related to a panel in my form, but I don't know how to do that. I'm a begginer and I don't have any experience with events. Thanks! 回答1: You must subscribe to event of Panel control - Click event. You can write the code below within Form's contructor: System.Windows.Forms.Panel panel; public Form() { InitializeComponent(); panel = new System.Windows.Forms.Panel(); panel.Location = new System.Drawing.Point(82, 132); panel.Size

问题 I have a DropDownList inside the itemEditor of my DataGrid. There are enough items in the DropDownList to justify scrollbars. You can see the scrollbars, and the mousewheel works fine. If you move the mouse over the scrollbars, they'll change appearance fine (mouseover is working). If you click on them, the DropDownList closes as if you'd clicked elsewhere in the data grid. There's a comment on the Adobe Forums that describe the same problem, but it is fairly old and has not been answered. I

问题 Windows Form I'm using the DragOver event on a layoutpanel and the DragEventArgs returns the X/Y coordinates of the mouse in relation to the screen. I know there is a function to translate this in to the position of the mouse over the control, but I'm having difficulty locating it. 回答1: Try Control.PointToClient and Control.PointToScreen. 来源： https://stackoverflow.com/questions/465545/how-to-get-mouse-position-over-a-certain-control

问题 Mouseup doesn't fire on scroll bar for elements dynamically added (except Firefox): CSS: #dBox { height: 100px; width: 230px; overflow - y: auto; } HTML: <input type="text" id="s"> JQuery: $(function() { $('#s').focus(function() { var $dbox = $('<ul id="dBox"></ul>'); for (i = 0; i < 10; i++) $dbox.append('<li>' + i + '</li>'); $(this).after($dbox); $dbox.bind("mouseup", function() { alert('in: '); //console.log ('in: '); }); }); }); // OR LIKE THIS $('#s').focus(function() { var $dbox = $('

问题 How can I get the handle of a window to be passed to Delphi by the user selecting the window (could be any other aplication's window) by clicking with the mouse on it. In my Delphi app I could have a button the user clicks that starts this detection process as well as a label displaying the clicked on window's title in the Delphi app. When the user is satisfied he selected the correct window he could click the button in my Delphi app (which will be modal) to stop the selection process and let

问题 BACKGROUND: I'm trying to create a "mouse hiding" application that hides the user's mouse from the screen after a set amount of time. I've tried many things, and using SetCursor only hides the mouse from the current application, mine must be able to sit in the tray (for example) and still function. I think I've found a solution with SetSystemCursor except for one problem. MY PROBLEM: I need to be able to capture any kind of mouse cursor, and replace the exact same kind of mouse cursor. When

问题 I've attached some MouseMove and MouseClick events to my program and next up is one of these: Get "global" mouse movement, so that I can read the mouse location even outside the form. Prevent my mouse from leaving the form in the first place. My project is a game so it'd be awesome to prevent the mouse leaving my form like most other games do (ofc. you can move it out if you switch focus with alt+tab fe.) and taking a look at answers to other questions asking for global mosue movement, they
