desktop

问题 From my application written in java I want to open a folder, using the operating system file explorer. I use Desktop.open(new File(path)) This works fine on windows, but on ubuntu 11.10 (linux) it doesn't work. Using the Desktop.open to open a file does work, both on ubuntu and windows. Using a step in between: File fPath=new File(fPath) and testing it with fPath.exists() and fPath.isDirectory() both gives true. using the Desktop.open(new File(path)) gives me this exception: java.io

问题 After a really deep drill down the web, this is my code which unfortunately doesnt send the keys as upper case :/ MapVirtualKey Implementation: const uint MAPVK_VK_TO_VSC = 0x00; const uint MAPVK_VSC_TO_VK = 0x01; const uint MAPVK_VK_TO_CHAR = 0x02; const uint MAPVK_VSC_TO_VK_EX = 0x03; const uint MAPVK_VK_TO_VSC_EX = 0x04; [DllImport("user32.dll")] public static extern int MapVirtualKey(uint uCode, uint uMapType); SendInput Implementation: struct INPUT { public UInt32 Type; public

问题 I developing some kind of chat application with PDF viewing functions on Flutter for Android and Linux desktop platforms. So i want to embed PDF viewer in flutter application using some kind of PDF reader or WebBrowser. There is no problems with PDF's on Android - more than 100 plugins on pub.dev for PDF's and WebViews, but none of them supported Linux desktop . I have tried to add Linux desktop support for Android and IOS plugins, but look's like all of them using PlatformView and webview

问题 I'm trying to click somewhere on the desktop, I'm using python with win32 api, I'm using python 32 bit but my computer is a 64 bit computer. I believe the lParam variable isn't holding the value I'm expecting, and I'm still a bit confused about this variable itself, lets say I import it from wintypes can anyone tell me how to use it? Why does my function below not work? I have a function as following, this doesn't seem to work: def clickDesktop(x=0, y=0): # Get handle to desktop window

问题 I have a .desktop file which associates my application (mmxfer) with specific mime types, and this works fine. When I right click a media file it gives me the option to use mmxfer to open it. But what if I want to associate a project with a specific file extension, say '.sply', which really just contains some data serialized from python and so doesn't have a unique mime-type? My current .desktop file is below. What should I change to associate mmxfer with '.sply' files? [Desktop Entry] Name

问题 Is there any function in OpenCV or Emgu CV desktop capture options? (addons, libs, classes) So I know we can capture camera in a very easy way, is there any option for desktop capturing that way? 回答1: I would recommend doing a screen capture outside of Emgu (ie, in non-Emgu C++/C#). The first step is to create a bitmap from the screen image. There are plenty of websites detailing methods of how to do this. I found this one helpful. Once you have a bitmap, it's easy to create new Emgu Image<,>
