问题 I have a button. On Button.MouseRightButtonDown, I'm calling Mouse.Capture(button), because I want to detect if someone releases right-click outside of the Button. I also have a Button.MouseLeave event registered. If someone right-click-drags the mouse off the button, I want this event to trigger. Unfortunately, it seems like Mouse.Capture somehow blocks MouseLeave from occuring. Does anyone know a workaround, or maybe can point out where I'm going wrong? (By the way, if anyone's curious what

问题 I have an old color picker utility written c++ that I coded years back and want to rewrite using c#. I implemented the global hook to pick pixels off the screen and so on. Everything is ok but... The cross cursor reverts to the pointer once the mouse moves outside the form and onto the desktop. This does not happen with my c++ code (MFC actually). How is this accomplished in c#? Thank you all. (I'm using this http://www.codeproject.com/Articles/7294/Processing-Global-Mouse-and-Keyboard-Hooks

问题 Many mice and keyboards have "zoom" buttons on them. These almost always generate Ctrl+Mouse Wheel messages to the applications, so they are easily accounted for by us programmers. But my current Logitech mouse has an additional feature. The zoom wheel indeed sends Ctrl+Mouse Wheel messages when scrolled (or, actually, tilted), but when I depress the zoom wheel, most programs restore the zoom level to the default, i.e. 100 %. What kind of message does the mouse send to the application in this

问题 I have C# MVC web app that has some textboxes that in IE9 you can enter in text, but you can't highlight via the mouse or via holding shift and the arrow keys. I've looked around on the web and i've found other people experiencing this, with no solution. One site i found claimed it was an issue with IE9 on pages that make multiple AJAX calls, which my site has but, removing AJAX really isn't a solution. Is there a way via code or via settings in IE9 so that users can highlight text in a

问题 This is a C# question. I have a form. On the form I have a panel. On the panel I have a picture box with a very large scrollable bitmap (Y >> 32768). The picture box click event does not fire when the picture box Y is greater than 32767. I understand that mouse clicks are limited to 16 bits. Is there way to get a mouse click of the underlying panel so I can compute Y from the scroll bar positon and the y coordinate of the panel? 回答1: Did you try another approach, such as "downscale" the

问题 I am trying to drag an element without keeping the mouse button down. The behavior I would like is : I click on a draggable item Drag my item without keeping mouse left click down : just follow the mouse as a cursor I click on a droppable container to confirm and append my item I am able to simulate this behavior if I add an alert box durring the start event. start : function(){ alert('test') }, Here is the fiddle : http://jsfiddle.net/QvRjL/103/ How is it possible to code this behavior

问题 How to add a click event listener to my custom control made with wxWidgets? The custom control uses wxWindow as the base. On the event list I see wxEVT_LEFT_DOWN wxEVT_LEFT_UP wxEVT_LEFT_DCLICK wxEVT_MIDDLE_DOWN wxEVT_MIDDLE_UP wxEVT_MIDDLE_DCLICK wxEVT_RIGHT_DOWN wxEVT_RIGHT_UP wxEVT_RIGHT_DCLICK wxEVT_MOTION wxEVT_ENTER_WINDOW wxEVT_LEAVE_WINDOW wxEVT_MOUSEWHEEL But there is no wxEVT_LEFT_CLICK or similar. 回答1: Typically, there is no "click" event (and in the case of wxWidgets - there isn't

问题 What I want to do I have a circular custom NSView subclass, and I want to change the appearance of the cursor when the mouse is hovering over the circular portions of the view, but not when over the portions of the view's rectangle that fall outside the circle. Here's an illustration. I would have inlined it with an image tag, but I'm too new to partake of such awesome features. What I know so far I know how to change the appearance of the cursor through NSCursor. I think that the best way to

问题 I tried a lot about searching for getting x and y position of mouse click inside the console of windows in C, but I cant find so I am posting here. I am creating my own text editor project (for fun) and I have to integrate a feature that whenever I click inside the console, the cursor moves to it (click x, y) I don't want to know how to move the cursor but I want to know how to get the click position . This code can receive all mouse and keyboard and mouse event even mouse clicked: #include

问题 I'm building a Windows Presentation Foundation control with Microsoft Blend. When I leave my control by pressing the left-mouse-button, the MouseLeave-Event is not raised. Why not? 回答1: This is intended behaviour: When you are doing mousedown on a control and leaving the control, the control STILL retains its "capture" on the mouse, meaning the control won't fire the MouseLeave-Event . The Mouse-Leave Event instead will be fired, once the Mousebutton is released outside of the control. To
