I've added a segmented control as the right bar button item of my navigation bar. The control has two segments and I'm attempting to use the control as bar button items. So I was wondering haw can I deselect a selected segment once the user preses it. I've already tried setting the selectedSegmentIndex property to -1 when the action method is called but that is preventing the segment from even being highlighted. Any idea on how can can get the segments to behave like bar button item?
do segmentedControl.momentary = YES; during setup or if using IB, select the Momentary checkbox in the Attributes Inspector.

I use the create command in livecode to dynamically create several objects (graphic, field, button) depending of some conditions. I use "lock screen" and set up all properties: width, height, textSize and many many more... Then "unlock screen".
Here is the problem:
The syntax create btn "Rider1" creates a standard button, but I need an ption menu button. In the project browser, there is also an option menu "Button: Rider2Number", but trying to modify the button that was created by script fails: there is no option menu or popup menu in the list of button types. There are opaque and standard and some variations. It seems like the standard button and the option menu are two different objects. Which prefix (like btn) I should use to create an option menu by script?
You have to first the the style of the button, then set its menuMode:
set the style of last button to "menu"
set the menuMode of last button to "comboBox"
There are two ways to fully set the required properties:
1- If you already have an option button (call it "XYZ"), you can:
create button
set the properties of last button to the properties of btn "XYZ"
You then will need to modify things, like its name and contents.
2- You can set the properties of the "templateButton" as required, perhaps, again, to the properties of btn "XYZ". Then all new buttons will start off that way. You will still have to modify a bit as in the above case.
This is all so that you need not set the many properties that distinguish one type from another; that is tedious. Look up the "templateButton" in the dictionary. This property can be set on the fly, to any number of different types of buttons. Do you see? If you had a suite of button styles, you set the properties of the templateButton to any of those on the fly, and then any newly created button will be of that type.
There is only one button object class. The difference between the many types you are interested in is the "menuMode". Check this out in the dictionary.
Currently in our web application, Trinidad JSF tr:table tag is used to display information in the table format. Upon using the attribute rowSelection=single, radio button displayed automatically for each row in a table and name/text next to this control is not visible to the user.
When user navigates with tab key to select the radio button control or user clicks on the same with mouse button, focus with dotted line is not displayed on the control.
What are the different approaches to display dotted line (provided by IE browser) around the radio button / check box control created by Irinidad JSF table tag?
End user requires this accessibility feature.
Right now, we are using,
myfaces-api-1.1.4.jar, myfaces-impl-1.1.4.jar,
trinidad-api-1.0.7.jar,trinidad-impl-1.0.7.jar,
Browser IE 8.0
Find your CSS file, look for any lines that have
outline: none;
And remove them.
This will fix most, if not all of your missing focus indicator problems. There might be scenarios where you have a hidden overflow that is causing the outline to not show up on some browsers. You would have to find those and fix them by adding appropriate focus styles.

I have a Windows form, and on it I dynamically create a number of widgets (toggle-boxes in this case). I can create anything from 0 to 64 widgets, depending on how many do-hickies the user has in the current collection. As the user changes from one collection to another, the widgets are deleted or created as needed. The form will resize according to how many widgets are displayed.
The user can check any number of them and perform certain processes on the checked items by selecting actions from a menu bar, toolbar or keyboard shortcuts. But I also want the user to be able to right-click on a single widget, which should bring up a popup menu with actions that can be performed on just the one clicked item, whether it's checked or not.
In itself, this is pretty straight forward. In the past I had done this kind of thing (in other languages) by having a single popup menu that pops up when the user clicks on any one of the dynamic controls. But I'm having a hard time doing this simple thing in Progress:
I am unable to have one popup menu that responds to the right-click of all the widgets. I tried creating a single popup menu, and then as I create each dynamic widget, I set its popup-menu attribute to this menu. The problem is that a menu can only be applied to one widget. Once I've assigned it to Widget1, I cannot assign it to Widget2. This leads one to think of creating a seperate but identical menu for each widget. And as the widgets are destroyed and recreated, so will these menus. In a single session I will create and destroy hundreds or even thousands of these identical menus, while the user might use one of them once or twice. Or not at all. So this does not seem like a good option to me.
My next solution would be to create a single menu which I can pop up programatically, but all attempts to programatically pop up a menu have failed. I have tried APPLY "MENU-DROP" TO MENU MyMenu and other similar things and I cannot for the life of me figure out how to do it. I also find it very difficult to search for information on this. It's as if nobody else has ever tried this, and the rare cases where someone has asked about it, there has been no satisfactory answers. I'm suspecting this cannot be done.
While trying all these things, I have also had endless problems with the events MOUSE-MENU-DOWN, MOUSE-MENU-UP and MOUSE-MENU-CLICK. MOUSE-MENU-CLICK seems to never happen, not for my dynamic widgets anyway. I am unable to figure out why. MOUSE-MENU-UP occurs sometimes, but it depends on what happens in MOUSE-MENU-DOWN and other events of the widgets as well as the widgets' parents. I have not been able to figure out exactly when it will or won't fire, it's very counter-intuitive. MOUSE-MENU-DOWN is the only one I can count on firing.
So: I can't show a menu programatically, I can only show it by right clicking on the menu's parent. The only way to avoid having hundreds of identical menus, is to have a popup menu on the parent of the widgets, for example the default frame.
With a static popup menu on the default frame, I can right-click on the widgets and the menu will come up, but it comes up if I click anywhere in the frame. I can disable the menu, and then in the right-click event of the widget, I enable it. This works very well the first time; if I click anywhere in the frame, nothing happens (the menu is diabled), but if I click on my widget, the menu is enabled and pops up. Yay! But now the menu is enabled and now it pops up if I right-click anywhere, on buttons, empty space, progress bars, etc. When do I disable it again? After the menu has popped up, the user can click anywhere and the menu will dissappear. There is no event that fires when the menu is closed, so I'm stuck.
Sorry about the long ramblings, I'll restate the question briefly: I want to have one popup menu that pops up when the user right-clicks one of a number of dynamically created widgets.
Using Tom's answer, this is how I implemented it:
/* Somewhere in Control Definitions... */
DEFINE MENU m_Popup
MENU-ITEM m_Test1 LABEL "Test 1"
MENU-ITEM m_Test2 LABEL "Test 2".
/* Somewhere, where I need to dynamically create the widgets. */
/* Loop through the items in the temp table and create a widget for each. */
FOR EACH ttItem BY ttItem.ItemName:
CREATE TOGGLE-BOX hWidget
ASSIGN
FRAME = FRAME DEFAULT-FRAME:HANDLE
LABEL = STRING(ttItem.ttItemName)
TRIGGERS:
ON MOUSE-MENU-DOWN PERSISTENT RUN GetMenu IN THIS-PROCEDURE.
END TRIGGERS.
END.
/* If the user right-clicks on any one of the widgets, this procedure */
/* is run with SELF being the widget that was clicked on. */
PROCEDURE GetMenu:
/* Remove the menu from its current owner and assign it to SELF. */
MENU m_Popup:OWNER:POPUP-MENU = ?.
SELF:POPUP-MENU = MENU m_Popup:HANDLE.
END PROCEDURE.
/* The user clicks on one of the menu items */
/* Here SELF is the menu item that was clicked. I can */
/* get m_Popup from SELF:PARENT and the widget it was */
/* was assigned to from SELF:PARENT:OWNER. */
ON CHOOSE OF MENU-ITEM m_Test1
DO:
MESSAGE "You selected " SELF:LABEL " for " SELF:PARENT:OWNER:LABEL.
END.
My buddy Mike Fechner (who is not currently on SO but who does this stuff a lot more than I do) tells me that, while this example is static, something very similar should work:
Procedure getMenu:
DEFINE INPUT PARAMETER phWidget AS HANDLE NO-UNDO.
DO WITH FRAME {&FRAME-NAME}:
FILL-IN-1:POPUP-MENU = ? .
FILL-IN-2:POPUP-MENU = ? .
FILL-IN-3:POPUP-MENU = ? .
END.
phWidget:POPUP-MENU = MENU POPUP-MENU-FILL-IN-1:HANDLE .
END procedure.
ON RIGHT-MOUSE-DOWN of all three fill-in’s you "RUN getMenu (SELF)." to steal the popup menu from whomever has it.
I have a tab bar iPhone application.
Tab bar #1 has a table view controller. It pushes a detail screen onto the stack.
On the top right hand corner there is a UIBarButton that calls and action sheet. This
is all built programmatically through code and all works fine.
Tab bar #2 calls a table view controller than then loads a map view. The map view annotation callouts then open up a detail screen. On this screen, I'd like a UIBarButton. So far, I cannot get this to work. The button does not show up.
Any ideas why?
Thanks,

UIBarButtonItem is not inherited from UIView.so u can't.
why dont u just use UIButton with Custom picture .

Is it possible to change the "Back" button text in a NavigationItem? At present, the caption of the back button assumes the title of the previous layer in the navigation stack, which is expected.
However, the NavigationItem's LeftBarButtonItem can be changed using code such as this:
UIBarButtonItem backButton = new UIBarButtonItem("Back", UIBarButtonItemStyle.Plain, null);
myNewView.NavigationItem.SetLeftBarButtonItem(backButton, true);
This works and the back button is displayed as expected, but the button is a square and does not navigate back to the previous layer as expected. I'm guessing that the correct event needs to be assigned to it, but I have no idea what it should be.
How would one go about ensuring that the new UIBarButtonItem has the correct event and arrow shape?
Note: I have also tried re-using the `LeftBarButtonItem' as suggested in this SO question, but I still don't know how to customize the button caption. I am probably just missing the obvious.
Thanks!
Set the title on the previous viewcontrollers navigationitem. I answered this before and will look up the link.
Ah, yes: Separate title in NavigationBar and navigation buttons
