I'm using Primefaces p:inplace such that when some text is clicked, it's replaced with an h:selectOneMenu, and from there the user can open the menu and select an option from the drop-down choices. It would be helpful (and alleviate an extra click) if when I clicked the p:inplace element, the selectOneMenu that appeared was already activated with its drop-down options showing, as if the user had clicked it. I've searched for this on Google to no avail, and was wondering if perhaps it is actually possible to do such a thing, even with JavaScript. (I can also use p:selectOneMenu or a selectOneListbox if need be, but it didn't seem like that would help.)
As you say, you could use a selectOneListBox, especially if you have few options(works just fine inside p:inplace). I've never heard of a request like that and I think it's all about the browser (there may be some restrictions regarding an auto-expand).
But you can do a thing that could please you: remove the default option, like:
<f:selectItem itemLabel="Select..." itemValue=""/>
and do some research to find out the most selected option and put that option as a default/first. So most of the people will not even have to expand the select menu.
I found this similar Stack Overflow question today (don't know how I missed it originally):
Can I open a dropdownlist using jQuery
Looks like our fears are right and there's no way to open the drop-down list itself, but a combination of CSS and modifying the element may give me the results I'm looking for. Thanks!

Using wxPython, is it possible to nest a combobox inside other combobox in a similar way to how submenus are nested within menus? I need something similar for a wx.Combobox or a wx.Choice.
Or is there any widget with which this can be done?
Well, there are some possibilities:
wx.lib.combotreebox.ComboTreeBox
wx.combo.OwnerDrawnComboBox
# possibly also:
wx.lib.popupctl
You might also use a button (or some control) to invoke a PopupMenu. It may be confusing for the user though, and you might get into trouble when trying to position the Popup menu correctly. Generally speaking, I advice not to be too creative when making UI.
Have you seen wxpython demo? It is a nice showcase of all possible widgets. You can obtain it from here: https://extras.wxpython.org/wxPython4/extras/
I am using the extlib Dialog component to display some data. I want the user to only close the dialog via a button I have in it.
I can't see any option to disable the close icon in the title bar. Can someone point me to the documentation on doing this? So far I've checked the wiki + extlib book (maybe I missed it?).
css rules, again! As far as I can see there's no "native" way to get rid of that close button (and to be honest, I don't think it's a really good idea to do so; see below). But using some css you of course can hide anything you want on your page.
Just give your dialog some custom styleClass; at runtime this custom class is then added to the dialog's outer div-container.
The close button itself is an link inside a span; the has tow style classes, one being "lotusClose".
Finally adding this piece of code to your style sheet will hide the button:
div.yourCustomClass a.lotusClose {display:none;}
Caveat:
The "close" button is there on purpose. And instead of hiding it I would rather add some kind of validation code to your dialog's close event. There are numerous examples, but maybe you just want to refer to dojotoolkit.org's reference for
dijit.Dialog
(section "Forms and Functionality in Dialogs).
Btw: since the dialog is based on dijit.Dialog you may also want to browse stackoverflow's dojo section.
I have created a webpage using Backbone.js and Marionette.js that mostly consists of a bootstrap accordion view that displays a list of items when the accordion header is clicked. Each item can also be clicked, which will show a hidden div of detailed information that pertains to that particular item.
I would like to make this site accessible to people who might not be using a mouse (Maybe they're visually impaired and using a screen reader? Maybe they just don't like clicking things? Either way.) I'm thinking that this would mean being able to press the Tab key to get to the accordion, pressing Space or Enter to open the accordion, Tabbing down (or down arrow key?) through the list items, and then using Space or Enter to show the selected item's hidden div.
I'm finding it difficult to find information on how to add a feature like this, since searches like "How to make an accessible website that can be used without a mouse" mostly turns up blogs on what a developer should do to add accessibility to a page, and not much on how to do it.
Currently, the page doesn't really respond to any keyboard buttons. Any tips or resources you could share would be extremely appreciated. I've been fiddling with ARIA role tags, but I'm either not doing it right or it's not the answer here.
You have to use tabindex
https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement.tabIndex
Screen readers automatically read whatever element is the activeElement
So I'm building a tool that allows a user to edit a whole bunch of preferences for various things. There are several groups of settings, too many to use a TabControl without creating arrow sliders to view all of the tabs, so I decided I would try and use a ListBox to list the groups of preferences, and then when they click on them, the settings that they can change show up to the right of the box.
I'm just not sure how to do this. Obviously it would invoke something in the OnSelectionChanged function of the ListBox, but I'm not sure where to go from there. Surely a dialog can have dynamic design, right? Would I mimic the creation of a tabbed-dialog where I create my designs and then bind them to the TabControl, and just do something similar for the ListBox? Again, it's not the ListBox itself that is dynamic. The user will click on "Settings A" from the ListBox, and to the right of the ListBox will be settings 1, 2, and 3 that each have textboxs/radios/checks.
Any hints on how I can accomplish this? I just think it looks nicer than having a whole bunch of tabs lined up across the top of the box. Thanks in advance to any brilliant minds who can help me out. I'm versed in C++, but I'm very much a beginner at VC++.
You can a vertical splitter with two panes:
one which contains the list
another one which contains the configuration dialogs you would normally use in a tab control
Each time the list selection changes you can load the appropriate dialog in the right pane. You can find a splitter tutorial here: http://www.codeproject.com/KB/wtl/wtl4mfc7.aspx
Currently working on a mobile app in J2ME and have questions with ChoiceGroup radio button answer options. Any suggestion on how to make it so that no default answer is selected? We've tried:
cg8.setSelectedIndex( -1, true ); But get an out of bounds exception error
and
cg8.setSelectedFlags( boolean[] ) with all false, but also get another error.
To get around this, we've also tried creating an invisible radio button and have that set as selected, but couldn't find a way to make an invisible radio button either.
Any thoughts or suggestions would be great appreciated!!
It sounds to me like the platform is enforcing an appropriate convention, although I must apologise for taking a purist standpoint here; this won't really answer your question.
Radio buttons are used when there are multiple exclusive choices, of which one must be made; it makes a certain amount of sense, therefore, for the user interface to ensure that something is always selected. Ideally, the initial selection in a radio group should always be a safe and sensible default.
As far as I know, the only way to not have any radio button pre-selected is to draw the control yourself. Re-implement a radio button list using a Canvas or a CustomItem.
It's a lot of work, unfortunately.
You should look into LWUIT as it may have an intermediary solution.
