main

问题 I want to keep total control over my game from the Main MovieClip and nowhere else. But I don't want to pass its instance through constructors neither do any .parent reference thingy from its children. Seems too workaroundish and unstable. A sample situation: public class Main extends MovieClip { public function Main() { addChild(new MainMenu()); } public function startGame():void { trace("Game started"); } } public class MainMenu extends Sprite { public function MainMenu() { var option

问题 Can we call main method inside main? public static void main(String[] args) { main({"a","b","c"}); } Tried to google.Can't find the link. Sorry if the question is trivial 回答1: You can but using the correct format main(new String[] {"a","b","c"}); should give StackOverFlowError (not tested) 回答2: You will get StackOverFlowError. If you call endless recursive calls/deep function recursions. Thrown when a stack overflow occurs because an application recurses too deeply. You need to pass String

问题 My application is written in delphi. For some reason the main menu does not behave anymore like it did until yesterday (I probably touched some property without knowing). Now when I click on a menu item with sub-items, though the arrow is located to the right, the submenu keeps opening to the left. What is the reason and how do I restore it back? 回答1: As revealed in the comments to the question, this is not programming related. There's a setting that does this in tablet pc settings in control

问题 This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, visit the help center. Closed 8 years ago . I'm thinking this is possible, but the compiler is complaining it cannot access the protected/private members of my class. I've tried moving stuff around

问题 You can often see this (variation a): def main(): do_something() do_sth_else() if __name__ == '__main__': main() And I am now wondering why not this (variation b): if __name__ == '__main__': do_something() do_sth_else() Or at least this (variation c): if __name__ == '__main__': def main(): do_something() do_sth_else() main() Of course the function calls inside main() might not be function calls, they just represent anything you might want to do in your main() function. So why do people prefer

问题 This question already has answers here : What should main() return in C and C++? (17 answers) Closed 2 years ago . My only exposure to programming has been Java,where I have not encountered (up to now) different conventions for writing the main method.I have been following to sources for learning c (K&R AND C Programming A Modern Approach) where they use very different forms of the main method (function). K&R version up to now: main() { blah blah blah; } C Programming A Modern Approach int

问题 I'm very newbie in android, I download an example from developer.android.com and I want to create a new class with his layout and modify the main class of the application to start with another layout. How can I achive this? (the starting class modification). [EDIT] I achieve this adding to my manifest this: <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> But when I do setContentView(R.layout

问题 The following question is about the unity game engine, but it could relate to any program trying to send data to a main thread, such as the UI thread. I am processing some data on a separate thread (position data a read asyncrously from a socket). However, I need to act on this data on the main thread (a game object's transform can only be accessed from the main thread). The approach I have in mind is to create a thread-safe queue and follow the producer-consumer pattern. The thread would

问题 Yesterday in the interview one question was asked to me that can main return struct ? I have no idea can any one please tell me is it possible or not,if yes why? 回答1: main can only return an int value in C (at least for hosted implementations ). 回答2: Section 5.1.2.2.1 of the C standard says no: The function called at program startup is named main. The implementation declares no prototype for this function. It shall be defined with a return type of int and with no parameters: int main(void) { /
