问题 I would like to change the wallpaper of all desktops (formerly "spaces") on a screen. As of OS X 10.6 there is a category to NSWorkspace which allows the setting of the wallpaper, however, when I use this function only the wallpaper of the current desktop gets changed and all the other desktops remain unchanged. I then looked at the desktop preferences plist and wrote a class that modifies it to reflect the changes I want (basically set a new image file path). After the new file was saved I

问题 I'd wish to set a wallpaper for Windows XP using C#. I've developed the code so it perfectly works in Windows 7, but apparently it's not the same for XP. I add that wallpaper as a resource, set its compile action as Content and Always copy. It, curiously, sets the correct Wallpaper name inside the Desktop's properties dialog. However, the wallpaper is not set. My code looks like this: public sealed class Wallpaper { Wallpaper() { } const int SPI_SETDESKWALLPAPER = 20; const int SPIF

问题 I'm working on a live wallpaper that incorporates some water ripple effects on touching the screen but I'm a little stuck. Would it be better to create multiple images and loop through them to create a ripple animation or would it be better to distort the bitmap a bit before I place it on the canvas?

问题 Does apple allows me to change the wallpaper of the iphone from my application? 回答1: The public iOS 4.0 API so far does not allow changing any of the iPhone wallpapers programmatically. Undocumented APIs are not supported by Apple, so no, I don't think they would allow it. However, technically it should be possible to do so. 回答2: Nope, no public APIs for it even with the latest SDK. You need to ask the user to save your image as a wallpaper manually. 来源： https://stackoverflow.com/questions

问题 How can I add a background image to my delphi form? I added a TImage, but now the labels aren't visible any more, and the texts of my checkboxes are in a blue "box" (blue is the background color i chose). This blue doesn't look very good on the background image, and the hidden labels also don't look good.

问题 I am building an album app. I want to set a photo in my own app as wallpaper. Is there some method available for doing so? update: I know there are already some similar questions posted. But they are out of time. So I am wondering if there is some method in iOS7 to implement so. 回答1: For apps going into the app store this isn't possible. Apps can't change anything outside of their environment this is because apps on iOS run in a sandboxed mode so they don't know anything about other apps that
