statusbar

问题 I am using this link! for cropping an image and after getting the cropped image somehow whole layout moves about 20dp upwards and hides behind the status bar (this is random behaviour i.e happens sometimes) I tried many things to fix this problem but couldn't get to the solution, mainly because I dont know what is causing the problem. This is a device specific problem, occurs occasionally in galaxy s and htc desire but frequently on samsung Ace. I tested app on samsung note and htc desire HD

问题 Quoting from this: https://developer.apple.com/library/ios/qa/qa1797/_index.html "Applications that use an opaque UINavigationController or UITabBarController automatically keep their content below the status bar." My root view controller is a UITabBarController however when that loads a table view controller the status bar is covering it. Is this documentation therefore incorrect? Note I'm not asking about how to solve this issue, there's plenty of questions about that already, I'm asking if

问题 I am trying to hide the status bar. I have tried the following things. This is for phones. I realize tablets can be different. It does hide the status bar when the layout has a bottom Tab. any ideas? android:theme="@android:style/Theme.NoTitleBar.Fullscreen" In the Manifest.XML I have added the above code. And in the onCreate() I have added the followingin the right place: requestWindowFeature(Window.FEATURE_NO_TITLE); // hide statusbar of Android // could also be done later getWindow()

问题 I am developing an application which should have some extra security features. In this case I have to disable/hide the status bar. I am running with Android 2.2. And also my device is rooted and if there is an ADB command to disable status bar, it would be fine as well. For now what I do is basically when user try to expand the status bar I collapse it by invoking some . But sometimes user can expand it and click on the items in status bar notifications. This code part will do this, public

问题 How can i efficiently display the status of a file when using a background thread? For instance, lets say i have a 100MB file: when i do the code below via a thread (just as an example) it runs in about 1 min: foreach(byte b in file.bytes) { WriteByte(b, xxx); } But... if i want to update the user i have to use a delegate to update the UI from the main thread, the code below takes - FOREVER - literally i don't know how long im still waiting, ive created this post and its not even 30% done.

问题 Is is possible to have labels in a QToolBar ? Something like the green text I draw on top of the app screenshot. I would like to have a set of actions in a toolbar, all them retated to some a system. Then another toolbar with another set of actions related to another system. So each toolbar would have a label named accordingly to the specific system. QApplication a(argc, argv); QMainWindow *w = new QMainWindow; QToolBar *barA = new QToolBar; barA->setToolButtonStyle(Qt:

问题 Ok, so I'm trying to figure out how to set a status bars label text to show information about the current control that a mouse is hovering over. I have seen this numerous times on many programs so I know it can be done and I'm sure there are explanations out there that could help me but I can't seem to find the right words to search for the answer unfortunately... The closest thing I could find was in the link below. I tried to utilize this but it gave me an error when I tried to set the text

问题 I know this question asked many time and I tested solutions which provide but none of them works. I want to hide StatusBar and Toolbar so I use following code to hide statusBar base on documentation: int flags = View.SYSTEM_UI_FLAG_FULLSCREEN | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION; getWindow().getDecorView().setSystemUiVisibility(flags); And this code for showing statusBar : getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE); It's works but When I hide statusBar my

问题 I read about this problem for the iPhone on the post here. The post says it's only a simulator problem. Right now I've got the same problem on my iPad app, on the device itself. The app has a status bar - but after hiding it in app i can't click/touch in that area (using iOS version 4.2). Thanks in advance. 回答1: If you're desperate enough, you could have your own window on top of the (invisible) status bar and process events in there. Set its windowLevel high enough and you're good to go.

问题 Already checked answers from StackOverflow to change status bar color for the whole app is to set View controller-based status bar appearance in info.plist to NO and Status bar style to UIStatusBarStyleLightContent . Well it did change from iPhone XS and lower, but iPhone XR and iPhone XS Max were not, Still solid black. I tried to find in code if there is a code that called UIStatusBarStyleDefault but I dont see it anywhere. My current fix now is to put this [[UIApplication sharedApplication
