Detecting when a treeview loads nodes?

由 半城伤御伤魂 提交于 2019-12-08 11:59:43
问题 My application uses a treeview to load a directory of files from a folder. But depending on the folder, it may take a while for the treeview to load so my program appears to freeze and the treeview is blank for some time but that is not the case. It just takes a longer time to load for larger folders. But I want to show a picturebox with an animated GIF in it to let the user know that everything is ok and they just need to wait. The problem is, I can't seem to find the event for this to

MySQL - Best method of saving and loading items

由 自闭症网瘾萝莉.ら 提交于 2019-12-08 11:31:26
问题 So on my older work, I had always used the 'text' data type to store items, like so: 0=4151:54;1=995:5000;2=521:1; So basically: slot=item:amount; I've been looking into finding the best ways of storing information in a sql database, and everywhere i go, it says that using text is a big performance hit. I was thinking of doing something else, like having a table with the following columns: id, owner_id, slot_id, item_id, amount Where as now i can just insert a row for each item a character

jQuery Mobile: Dynamic content not loading when I return to a page

由 ↘锁芯ラ 提交于 2019-12-08 10:49:01
问题 My data from getmovies.php is working correctly and loading into #moviesPage the FIRST time I load the page. However, if I navigate away from #moviesPage and then return to it the content does not reload. The header and footer appear and I can see that the unpopulated <ul> is also there, just not any of the dynamically loaded <li>s . My code is below. Any thoughts on how I can get my dynamic data to load when I return to a page? $( '#moviesPage' ).live( 'pagebeforecreate',function(event){

Loading a large number of images from a spritesheet

由 与世无争的帅哥 提交于 2019-12-08 07:42:28
I'm attempting to make a simple game of Pairs for Android. Program Structure: Menu.java (Menu activity initially loaded) Game.java (Game activity, started by Menu) GameThread.java (Handles gameloop, calls render process in GameView) GameView.java (Handles all drawing to the screen) Graphics.java (Stores loaded images) The Problem: The game features 15 different types of card, each of which requires around 14 frames for animation (flipping, destroying, etc). I'm currently reading these off a PNG spritesheet, and then chopping them into a Bitmap array (Bitmap[15][14]) using the following code:

Android googlemaps v2 finish loading event or callback

由 旧时模样 提交于 2019-12-08 00:27:25
问题 I want to do something after the google maps has loaded(maptiles have been filled) is there anyway to achieve that? 回答1: As noted by qubz, the ViewTreeObserver can be used to achieve a callback after the loading of the map has completed, so the user will get e.g. the correct location right after start-up: @Override public void onCreate(Bundle savedInstanceState) { // This is a small hack to enable a onMapLoadingCompleted-functionality to the user. final View mapView =

Can't access variables from dynamically loaded javascript

由 走远了吗. 提交于 2019-12-07 16:07:18
问题 I'm using a fairly simple system to load javascript dynamically: include = function (url) { var e = document.createElement("script"); e.src = url; e.type="text/javascript"; document.getElementsByTagName("head")[0].appendChild(e); }; Let's say I have a file test.js which has the following contents: var foo = 4; Now, in my original script, I want to use include(test.js); console.log(foo); However, I get a 'foo has not been defined' error on this.
