mouse

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 mousePressed event after the glassPane has been acivated. Now here comes the problem, this workaround only

Is it possible to prevent opera mouse gestures for right button? I have web app on html5 and I decided to use right mouse button. But it doesnt work in opera, because opera has mouse gestures. event.preventDefault(); // it doesn't work May be anybody knows? Thank you. It doesn't actually have anything to do with gestures specifically. Opera doesn't allow scripts to detect context menu events by default so you'd have to ask users to change their site preferences for your site to allow scripts to detect context menu events. Right click -> Edit Site Preferences -> Scripting (tab) -> Allow scripts

让Panel对Mouse滚轮事件(Wheel)有感觉 最近有看到朋友谈到“panel 选轴捆动与 textbox 疑问”。 如果TextBox在Panel中的话，Focus在TextBox上，滑动Mouse滚轮的话，如果Panel有Scroll的话，是会跟着滑动的! 但是如果Focus所在的TextBox不在Panel之中，那Mouse在有Scroll的Panel上滑动Mouse滚轮，panel是不会理你的哦! 因为Panel默认是不会吃Focus的哦! 而且目前Focus是在Panel外面的TextBox上，不可以切换Focus过来! 那要如何做呢? 在网络上有找到解法“Mouse Wheel Event (C#)”，马上记录下来。 在Winform上放了一个Panel里面放了一堆Button，并设定AutoScroll=True，再放一个TextBox在Panel外面，如下的画面， 而程序中作法如下， 1.您的form要实践 IMessageFilter 2.加入PreFilterMessage method 3.在Form的建构函数中加入Application.AddMessageFilter(this); Code如下， using System; using System.Drawing; using System.Runtime.InteropServices;

using vanilla js. Any way to grab the "right-click" (option-click) from OSX? function clickey(e) { if(event.button==2 || /*how you'd do it in Java=)*/ e.getButton() == MouseButton.BUTTON3 ) ... } but in js, how do eeet? You need to listen to the contextmenu event. This is triggered when the context menu should be shown. So either if the right mouse butten or or ctrl + mouse . If it is not supported then you can try to check the mousedown event where button is 2 and ctrlKey is true if it is triggered by using ctrl + mouse document.addEventListener("contextmenu",function(event){ }); OR

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've been experimenting with custom skins hoping to find a way to trap the mouse event, but have been

I have a user control called GameButton that has a label inside it. When I add the user control to my form, and add a click event to it, its triggered when you click on the background of the custom button, but not the text in the label? How would I fix this without adding a bunch of click events inside the user controls code? edit: UI framework: winforms ImGreg If I am understanding you properly, your GameButton usercontrol will fire the event when clicked on, but not when the label is clicked on -- and you want both. This is because the label (a control) is on top of the background. Therefore

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. Try Control.PointToClient and Control.PointToScreen . 来源： https://stackoverflow.com/questions/465545/how-to-get-mouse-position-over-a-certain-control
