parent-child

问题 I am writing a class library(API) in C#. The class is non-static and contains several public events. Is it possible to trigger those events from a static method in a separate class? For example... class nonStaticDLLCLASS { public event Event1; public CallStaticMethod() { StaticTestClass.GoStaticMethod(); } } class StaticTestClass { public static GoStaticMethod() { // Here I want to fire Event1 in the nonStaticDLLCLASS // I know the following line is not correct but can I do something like

问题 I am building a simple application that opens a QDialog , and from a QComboBox that belongs to the child, I can select an item and see some information. What I need to do is to get some of the information shown by the selected item from the comboBox (or another data of this child).

问题 I'd like to have dtrace script that print new processes' cmdline and their matching parent name. i.e. : if I ran /Users/bla/myexec arg1 arg2 arg3 from bash I will get something like : parent is bash process is --> /Users/bla/myexec arg1 arg2 arg3 After searching here and here I came up with the following solution : #!/usr/sbin/dtrace -s proc:::exec { self->pexecname = execname; } proc:::exec-success / self->pexecname != 0 / { this->isx64=(curproc->p_flag & P_LP64)!=0; #define SELECT_64_86(x64

问题 I'm running into a problem working around limitations in Zend Framework 1.x and I can't replace or update it at the moment. I have a novel idea but I'm not sure if it's possible. The basic question is Is it possible to instantiate an extending child object, but then extract the parent object afterward for serialization? To illustrate why, essentially the Zend_Mail class has some really stupid limitations and type checks on its methods, in my case specifically $mail->setType() . My thought is

问题 Right off the bat I dont think the wording of the question is accurate, I just dont really know what to write. That being said, I have 3 txt files that I am loading into this program, Dudes, Tunes, and Bands. Dudes is formatted like this name|instrument, Tunes like this; songName|composer|band|coverArtists1|coverArtists2|etc. And band like this; bandName|bandType|member1|member2|etc. The "|" is where I split the data so each line of the text files become arrays of strings. What I am trying to

问题 This question already has answers here : Is there a CSS parent selector? (31 answers) Closed 5 years ago . I have block parent elements that have at least one inline-block child element which may or may not meet a specific condition. I'd like to style the parent to highlight the presence of a particular child type (below, "special" class): <parent> <child class="normal">Text</child> </parent> <parent> <child class="special">Text</child> </parent> Normally, this wouldn't be an issue since I

问题 I have a main AppDelegate class (MacOS development, not iOS) initiating a child class with myChildClassObject=[[myChildClass alloc]init:self]; So I do send the parent reference to the child class. However how can I access an object of my parent class from my child class ? I tried with parent.myObject but it doesn't find it. My parent class is defined like this: @interface AppDelegate : NSObject <NSApplicationDelegate> { NSView *myObject; } @property (nonatomic, readwrite, retain) NSView
