问题 I had some help with this earlier and yet somehow I can no longer get it to work. I need a text box to appear if an 'other' check box is checked, and dissappear when it isn't checked.

Hiding ListViewItem instead of removing it?

由 拥有回忆 提交于 2019-12-11 03:35:48
问题 The common way to NOT display a ListViewItem is to remove it. I my current project, this makes things too complicated compared to the possibility of just hiding the item. Is there any way to hide a ListViewItem instead of removing it? What I have tried so far: Using OwnerDraw=true , the DrawItem event doesn't provide anything useful: Bounds is read-only and changing properties of Item is useless. Inherit ListView and override WndProc was my next attempt, but I was not able to find any of the

is there anyway to define public or private or protected classes in PHP

由 不问归期 提交于 2019-12-11 02:41:58
问题 Is there anyway to create public or private or protected classes in a namespace just like java? like... namespace foo; public class Account { ....... } private class PrivateAccount { ....... } please let me know if there is any workaround to do this in PHP. 回答1: Typically what you do is declare the constructor of the class private. Then you can create a separate static function in the class that will do some checks (i.e. check the namespace) and conditionally return an instance of the class

Initialize member of abstract class without subclasses having write access

How to access fields declared inside anonymous object?

问题 Java lets you declare new fields inside anonymous classes, but I can't figure out how to access them from outside, even setting them to public doesn't let me. class A { public static void main(String[] args) { Object o = new Object() { public int x = 0; { System.out.println("x: " + x++); System.out.println("x: " + x++); } }; System.out.println(o.x); } } I get this compiler error: $ javac A.java && java A A.java:10: cannot find symbol symbol : variable x location: class java.lang.Object System

C symbol visibility in static archives

由 匆匆过客 提交于 2019-12-11 02:11:48
问题 I have files foo.c bar.c and baz.c, plus wrapper code myfn.c defining a function myfn() that uses code and data from those other files. I would like to create something like an object file or archive, myfn.o or libmyfn.a, so that myfn() can be made available to other projects without also exporting a load of symbols from {foo,bar,baz}.o as well. What's the right way to do that in Linux/gcc? Thanks. Update: I've found one way of doing it. I should've emphasised originally that this was about

-fvisibility=hidden not passed by compiler for Debug builds

由 余生颓废 提交于 2019-12-11 00:44:34
问题 I am building a project in which I have enabled GCC_INLINES_ARE_PRIVATE_EXTERN and GCC_SYMBOLS_PRIVATE_EXTERN because I am consuming static libraries that were pre-built with those flags on. However, when I build my project for Debug -fvisibility=hidden is not included in the compiler flags, but it does get included when I build my project for Release. Is there any other flag that I need to turn on to make this happen? 回答1: This is old, but it it seems the conflict comes from the Enable
