mouse-cursor

问题 Is it possible to disable the mouse feedback cursor when a process begins from within the process? I know you can use the STARTF_FORCEOFFFEEDBACK flag when creating the process, and that the feedback cursor will turn off when the process displays a window. However, I do not have control over the code that creates my process and my process is only used for background computation, so it does not display a window. Anybody know of any system calls I can make to turn off the feedback cursor, other

问题 I want to get the height and width of a .cur file without look into its format. I try to use LoadCursorFromFile() to get a HCURSOR, I suppose there is a API function to obtain the HCURSOR infos, but I find that GetCursorInfo() is not I want at all. Is there any way to get the height and width of a HCURSOR object? 回答1: There is some overlap in the APIs between icons and cursors in Windows. You can call GetIconInfoEx with an HCURSOR as well as with an HICON. The structure you get back will have

问题 I have a small Qt application that displays an image to the screen (more on that including source code here: Qt: Modify alpha channel transparency of a windowless QLabel). By default, Qt is inserting a mouse pointer on top of my image. For my application, I do not need any physical user interaction with Qt and thus have no need for a mouse pointer. I have used the following code to hide the mouse pointer, but it only hides the mouse once the mouse has been physically moved, and only within

问题 I recently bought a new computer and I moved my projects from my old one to my new one. I did a compilation on all of my projects and they all worked fine, and most of them still do on my new computer, but one project in particular wouldn't display the custom cursor that I had moved. I made sure that I moved the picture with the project just to rule that out. I rewrote the source to match the new location on my new computer, but it still won't display. It gives me the error message: Exception

问题 When viewing my site, the cursor only changes to the gloved hand for <a> tags, not <button> tags. Is there a reason for this? Here is my code (the button tags have an id of #more in css3). #more { background:none; border:none; color:#FFF; font-family:Verdana, Geneva, sans-serif; } 回答1: see: https://developer.mozilla.org/en-US/docs/Web/CSS/cursor so you need to add: cursor:pointer; In your case use: #more { background:none; border:none; color:#FFF; font-family:Verdana, Geneva, sans-serif;

问题 I'm trying to snap my mouse cursor over the approve button by default on a JFileChooser but I cannot find any examples anywhere where this has been done before. I have tried using hard coded x,y positions but this is useless when I run my application on a different pc. Any help would be appreciated, my code is as follows: FileOpenDialog fileChooser = new FileOpenDialog(index); fileChooser.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent evt) { } }); /

问题 I have a Flash application that requires Flash version 10.0 to run. I want to add native mouse cursors, which were introduced in Flash 10.2, but I don't want to require all my users to upgrade, and I don't want to have to compile two separate versions of my app. Is there any way at runtime I can detect if the cursors are available, and then use them? It seems like if you only compile for Flash 10.0, it marks the SWF version header "10", and you have no access to the new APIs. And if you

问题 I have the following CSS that hides the mouse cursor for anything on the web page. It works perfectly in Firefox, but in IE and Chrome, it doesn't work. html { cursor: none; } In Chrome, I always see the mouse pointer. In IE, however, I see whatever cursor was last 'active' when it entered the screen. Presumably it's keeping the last selection instead of removing it. 回答1: This property cursor:none; isn't part of the standard See here w3c cursor CSS properties. You might want to look into
