to put simply, have menus in menu bar that, when @ start of application, goes on list when expand it. however, if list ever updated, menus go behind list, covering menu items. i have theorized need when list updated, make tell list go layer (which set bottom, lowest on list in application using netbeans). but, not know call tell program keep list there. (i still new java , learning go) have idea on how wish or better, causing problem? thank time , have wonderful day :3 you should use jlist instead of list. the problem components in java.awt have peer components, native os components, whereas swing 100% java. cannot write on these native peers... @ least not in java.

i trying create excel formula represent logic: if (b8 < 0 & a8 > 0), b8+a8 or if (b8 < 0 & a8 < 0), b8-a8 or if (b8 > 0 & a8 > 0), b8-a8 i can't seem syntax right. alternatively, following put more closely/literally: =if(and(b8<0,a8>0),b8+a8, if(and(b8<0,a8<0), b8-a8, if(and(b8>0,a8>0), b8-a8, "null?" ))) should trick. wasn't sure put if none of cases fail, showing "null?" .. change desired. (but suspect pascx64's more efficient in long run ;) )

possible duplicate: passing pointer representing 2d array function in c++ i trying pass 2-dimensional array function through pointer , want modify values. #include <stdio.h> void func(int **ptr); int main() { int array[2][2] = { {2, 5}, {3, 6} }; func(array); printf("%d", array[0][0]); getch(); } void func(int **ptr) { int i, j; (i = 0; < 2; i++) { (j = 0; j < 2; j++) { ptr[i][j] = 8; } } } but program crashes this. did wrong? it crashes because array isn't pointer pointer, try reading array values if they're pointers, array contains data without pointer. array adjacent in memory, accept single pointer , cast when calling function: func((int*)array); ... void func(int *ptr) { int i, j; (i = 0; < 2; i++) { (j = 0; j < 2; j++) { ptr[i+j*2]=8; } } }

this question has answer here: making flat list out of list of lists in python 23 answers i trying write function take in number of different lists or tuples arguments , return 1 big list. def addify(*args): big_list = list() iterable in args: if isinstance(iterable, tuple): big_list.extend(list(iterable)) else: big_list.extend(iterable) return big_list >>> print addify((1,2,3), [2, 5, 3], (3,1,3), [3, 2344, 3]) [1, 2, 3, 2, 5, 3, 3, 1, 3, 3, 2344, 3] i learning args , kwargs , , code working right, seems code simple. there must better way writing long function check if argument tuple , if add convert list , add on. seems bloated. itertools.chain looking for: >>> itertools import chain >>> print list(chain((1,2,3), [2, 5, 3], (3,1,3), [3, 2344, 3])) [1, 2, 3, 2, 5, 3, 3,...

this mdn article (citing this blog post ) teaches how render html content canvas. i've implemented in project , works. but on "retina" displays, draws canvas @ half of full resolution display supports. example, if have canvas on render html string "hello" , next canvas put <span>hello</span> , latter (rendered browser usual way) smoother , crisper former (rendered html onto canvas, using technique in links above, uses svg , image ). i believe there's way detect retina displays, know when higher resolution needed, given in this source code . when detect i'm on retina display, question is: is there method renders html canvas @ full retina resolution? look @ post var image = new image(); var ratio = window.devicepixelratio || 1; var canvas = document.queryselector("canvas"); var context = canvas.getcontext("2d"); // 1. ensure element size stays same. canvas.style.width = canvas.width + "px...

i'm trying parse values of cookie this: import re m = re.search("(.*?)=(.*?); path=(.*?); domain=(.*?)", "name=value1; path=/; domain=my.domain.com") print (m.group(0)) result this: name=value1; path=/; domain= my question is: why not match @ last non-greedy position? expected result be: name=value1; path=/; domain=my.domain.com of course, change greedy mode or use end of line character ( $ ) i'd understand why it's not working expected work :) non-greedy means match little can while still allowing entire match succeed. * means "zero or more". least can match zero. matches 0 , match succeeds. the other occurrences of .*? in regex cannot match zero, because entire regex fail match.

i need map values ranging between lowerbound , upperbound value. illustrative example: for example, imagine have gps system has users subscribed it. system able provide me distance of user point. based on distance of user want assign them id. thus users in distance 1 100 id: 8.4 101 200 id: 7.2 201 300 id: 3.6 401 600 id: 4.1 and on... my approach: so did, created std::map initializing follows: std::map<int, double> distancetoidmap; distancetoidmap = { {100, 8.4}, {200, 7.2}, {300, 3.6}, }; then use code id given distance: double rounduptohundred = std::ceil(realdistance / 100.0) * 100; double powerfordistance = distancetoidmap.at(rounduptohundred); however approach breaks down 401 600 distance, because ceiling nearest hundred distance of 400+ value 500 don't have entry in map. of course trivial solution add entry 500 distancetoidmap not how want handle problem. i have map ...
