  - by Alex Trott

  Currently my tableview looks like this: as you can see, cell.textLabel and cell.detailTextLable both load this background, and i can't work out how to get them to stop loading the background, and for it only to be the backing on the cell. Here's my current code to change the cell: - (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath { [cell setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"tableCell.png"]]]; } How can i get round this problem? Thanks in advance.

• How to test an iPhone application update?

  - by sfkaos

  I already have an iPhone application (version 1.0) available in the App Store and am ready to submit a newer version (version 1.1). How do I test the new upgrade to make sure that the current sqlite database and property list files on the earlier version do not get deleted/overwritten etc? The new version assumes the old data in both the sqlite database and property lists remain. Or better yet, is there a resource I can use to walk me through what to watch for when developing an application update?

• java swing, simulate JTable terminateEditOnFocusLost behaviour

  - by blow

  Hi all, i'm using putClientProperty("terminateEditOnFocusLost", Boolean); to make jtable end editing and clear current selected rows when it lose focus or when simply click over an other GUI component. This is very useful, but with "terminateEditOnFocusLost" there are some strange behaviours if it is used with editCellAt and changeSelection. There are also some undesiderable TableModelEvents fired for some fake table updates. So, im looking for an hack to simulate "terminateEditOnFocusLost without using it, is this possibile? Thanks all.

• include link list depending on category

  - by user117701

  I want to display the linklist widget only on a certain category. The current way the sidebar is fetched is: if (!function_exists('dynamic_sidebar') || !dynamic_sidebar(1)) Which doesnt give me a say in the calling of the links widget. If i put an if clause there, then the rest of the widgets dont get loaded. So i either need to customize the links widget it self or find a way to call the links widget directly? And how do i check which category i'm on?

• Fading Element on Scroll

  - by user179846

  I'm curious how I can create a DIV (or anything really) that I can fade (or change opacity of) when a user scrolls down the page. This DIV would sit at the top of the page, but only be clearly visible when at the very top of the page. Additionally, it would be ideal if I I could have this element fade back in onmouseover, regardless of the current scrolled position on the page.
