savestate

问题 I have used multiple Fragments in my Project. I want to save a Fragment's state and restore this state when I come back to this. In this Fragment I show multiple images which change on button click.

问题 I have a big iOS-project with many folders / groups. When I quit and restart Xcode, all folders in the Project Navigator are shown expanded, so I have to collapse most of them manually. Is it possible to save the state of the Project Navigator , so that when Xcode restarts the same folders are collapsed / expanded as before? 回答1: The solution was to delete this file: MyProjectName.xcodeproj > project.xcworkspace > xcuserdata > myusername.xcuserdatad > UserInterfaceState.xcuserstate This file

问题 I am creating a software in WPF, and, in the software, the User can load an image, and configure a map. Basically, once the Image (of a map) is loaded the user can add other images (like a picture of a treasure or a monster, etc) drag and drop them within the image of the Map. When the user closes the software, and reopens it, I want the last image opened, and the UI elements added to be in the same place, like how the User had set up, before closing the application. One way I can think of,

问题 I have an app with a WebView. There is a page with Upload Photo button so I use the openFileChooser. Sometimes I have a problem when the camera is chosen. The activity restarts and the webview is back on the beginning. How I can save the state of the activity?

问题 From this page of Android SDK The default implementation takes care of most of the UI per-instance state for you by calling onSaveInstanceState() on each view in the hierarchy that has an id, and by saving the id of the currently focused view (all of which is restored by the default implementation of onRestoreInstanceState(Bundle)). So is there a mechanism that automatically saves the Activity state without saving value from each element in the activity? I am confused about the above

问题 I've searched many threads and still cannot find the answer to my question. I'm working on an Android app which uses WebView . I use onSaveInstanceState() and onRestoreInstanceState() to save the WebView state like this: @Override public void onSaveInstanceState(Bundle savedInstanceState) { webView.saveState(savedInstanceState); } and @Override public void onRestoreInstanceState(Bundle savedInstanceState) { webView.restoreState(savedInstanceState); } I also have this in my onCreate() : public

问题 I have a small program in winforms that holds 3 buttons. Thus far the program lets the user change a the color of another button by clicking the corresponding button While the third button does not do anything yet. What I want to do is to let the user save changes made to the form (save the form state). So when the form is reopened it opens in that same state as saved. I hope I am being clear about what I am after Here is a visualization of the form: The code that i have so far if any help:

问题 I'm building a VSTO add-in for Powerpoint 2010 and the options the add-in sets apply to the currently open file instead of a per-user config. Can I save these options in the current file (I mean, add custom XML to the .PPTX file)? If so, how? Thanks for your help. 回答1: If your Options are not too complex, I would go for Document Custom Properties. The following question illustrates how to use Custom Properties with Excel, they are supported in PowerPoint as well so this should provide a good

问题 I have a Eclipse plugin that uses a view which extends ViewPart . ViewPart has a saveState method which requires an IMemento . I added my code to saveState and the corresponding init method and it works. Unfortunately, saveState is only called if the entire workspace is shutting down. My view is not of such great importance that I can expect it to be opened the entire time. Hence, it would be cool if saveState would be called on view closure. I found a view-part listener as mean to react on
