• Setting a ListView Divider in code

  - by deSelby

  One of my ListView's needs to be created in code. When I specify a ListView in xml, I can set a dividerHeight and assign a color to the divider. But apparently, in code a color is not acceptable nor is pointing to a resource id. Only a Drawable is acceptable - and I haven't gotten to that chapter yet. Can someone point me to an example of setting a ListView divider in code?

• Address of default RHEL YUM Repository

  - by El Guapo

  Does anyone know the address of the default RHEL repository? We rent a server that is hosted by a third-party and one of our users seems to have "deleted" a lot of the RHN packages from our box; included was the rhn-yum-plugin. I really don't want to waste one our support requests on having them load up the DVD into the box and re-initializing the RHN software. Thanks.

• Setting column width in Table View

  - by Jeremy

  I am having a hard time understanding how to change the width of columns when creating a table view. I know you can set the width in pixels of a column but that is not what I want to do. Say, for instance, I have 2 columns and want each column to take up half the screen. How do I do this without explicitly setting the pixels, so that my code can work on multiple screen sizes?

  - by DooriBar

  According to the documentation of iconv_open() over: http://www.gnu.org/software/libiconv/documentation/libiconv/iconv_open.3.html "//TRANSLIT" means that when a character cannot be represented in the target character set, it can be approximated through one or several characters. and: "//IGNORE" means that characters that cannot be represented in the target character set will be silently discarded. But what is the default behavior, when neither are specified? Thanks, Doori Bar

• trouble setting node['chef-client']['interval']

  - by atiniir

  I've searched many places and haven't get found the answer to this, I suspect I'm missing something either fundamental or basic (maybe both) I'm using the chef-client::windows_service recipe and trying to set the interval and can't seem to sort it out. I've tried at the role level with: { "defaults": { "chef_client": { "interval":15 } }, "overrides":{ } } and at the node level with: { "chef_client": { "interval":25 }, "tags":[] } but the interval on the node is still 1800 (default)

• unobtrusive "default" text in input WITHOUT jQuery

  - by Adam Kiss

  Hello, i'm trying to write unobtrusive default/placeholder text in input (actually, relatively placed label over input, which hides on onFocus, and stays hidden if input isn't empty on onBlur), but I don't want to use jQuery, because this is the only javascript used on page - therefore using jQuery seems a bit over the top. Please, how can I do this without jQuery? Thank you.
