This has caused controversy. Since the birth of C langu

in a document, and the number of document pages is presented to the user so that they can select a range to print. A print service may optimize printing for content types, such as documents or photos.An instance of this class is created by the application that needs to be printed, and the callback function is called after the content is successfully typeset (laying out the contents) PrintDocumentAdapter.LayoutResultCallback.onLayoutFinished( PrintDocumentInfo, boolean) . This process is carried

operation in a browser, it is necessary for developers to know how to reduce the number of reflow, and the effects of different document properties (DOM level, CSS efficiency, no type style change) on the number of reflow. Sometimes an element in a Reflow page reflow its parent element and all its child elements.Some of the factors that trigger reflow: resizing windows (resizing the window) Change font (changing the font) Add or remove a style sheet (Adding or removing a stylesheet) C

Key code: when using Fragment, you must note that the imported package must be consistent. The imported Fragment in mainActivity. must be consistent with the Fragment imported on the Fragment interface as follows. import android.support.v4.app.Fragment; Package com. imooc. tab02; import android.

IOS-basic development knowledge The ability of an object to obtain its type at runtime is called introspection. There are multiple methods to achieve this in introspection. Determine the object type-(BOOL) isKindOfClass: classObj determine whether it is an instance of this class or a subclass of this class-(BOOL) isMemberOfClass: classObj determine whether it is instance 1 of this class: person * person = [[Person alloc] init]; // parent class Teacher * teacher = [[Teacher alloc] init]; // subcl
