Detecting out-of-view flex controls - apache-flex

In my flex app I have custom tooltips on buttons that hide and show based on user context.
The problem that I dealing with is that when I call my showTips() function I only want to show tooltips on the buttons that visible in the view. So buttons that on a un-selected tab (tabNavigator) should not show the tooltips.
For some reason all tooltips are showing.
Is there a way to detect if a button is not in current view, like on a un-selected tab?

If you gave us some code I could check this out, but would this work?
if(button.parent.visible) { showTip(button);}

Instead of custom coding for each button, make use your tabnavigator's creation policy is set to "auto".

Is it possible to set a drop down widget to be required?

Was wondering if it was possible to have a drop down widget in app maker be required. In other words, users could not click submit unless they had selected a value from a down down menu. Kind of like how validation on text boxes.
When looking at the property editor for a drop down widget I don't see anything that will allow me to set the above requirement out of the box.
Below is the property editor for a drop down, you will notice there is no validation options.
Below that is the text box property editor with the validation option expanded. I basically need the same functionality for my drop down menu.
If anyone dealt with a similar issue I would appreciate any input.
Of course you have that option.
Look under DropDown menu you will find option called allowNull, deselect that option. Also select validationDisplay check box from 'Other' menu and users will have to choose from a drop down menu always.
Below are the screen for your reference,
Dropdown menu allowNull option,
Other menu validationDisplay option,

Eclipse Scout Neon: Menu and Tooltip on a field

This is a screenshot if you put a Menu on a StringField:

This is a screenshot if you put a Menu and a Tooltip on a StringField:
the (i) icon from the tooltip is the button to open the menu list.
the tooltip text is not visible.
Did I miss something?
Is this a known issue?
Yes, this is a known issue. If a tooltip and a menu are provided, a combined popup should be shown including the tooltip text and the menu items. But this has not been implemented yet. Feel free to open a bug.
However, if you only have one action you could set the property hasAction to true instead of using a menu. This will bring up a clickable arrow inside the field, actually intended to follow a link or open the email client. But you could also use it for any other action as well, just implement execAction. Please note that this feature is only available for string fields so far.

Flex form inside Pop up window - Tab (order) between forms not working

when user clicks on Add button, then a pop up button will be opened with certain form elements (like textinput, date field, text area).. When i used 'TAB' inside this form,it is not working. I found in couple of Questions / forums that we need to create an instance of FocusManager and then bring/activate focus for the pop up. But still i didn't see the tab working inside the form. In order to tab order working inside a pop up, what steps we need to follow.
I tried using focusmanager and property like tabfocusenabled, tabenabled and also added taborder inside each form element. But no luck.
Iam using Flash Builder 4.5 and using spark components for development.
Is there any workaround for this problem?
Thanks in Advance,

Thanks for all your responses.
Finally the issue has been solved by one of my colleague. Problem is , the form has been loaded inside Horizontal accordion (flexlib HACCORDION). So inorder to draw focus inside the accordion to child elements, we need to add 'hasFocusableChildren="true"' for the HAccordion (horizontal accordion component). Adding this property solves the tab order problem.
I have also pasted the code below:

Disable Ribbon Button

I want to disable and NOT hide a ribbon button (specifically Ribbon.ListItem.New.NewListItem) on a particular List type. On web I could find a lot many posts showing me ways to remove/hide buttons but none really worthwhile which could tell me how can I just disable an alrteady existing sharepoint button in my custom List type.
e.g. Following code does remove the button instead of hiding.
Id="RemoveRibbonButton"
RegistrationType="List"
RegistrationId="213908"
Location="CommandUI.Ribbon">
This can be done through Javascript on the client side. Check out this article for an example.

Tree Show toolTip during drag

I am denying a user the ability to drop into my tree during certain conditions, it's all going well, but I want to tell the user why I'm denying the drop. I would prefer to do it with a toolTip, but it doesn't seem to work. Can I not have a toolTip during a drag operation? How can I force one?
Flex seems to treat toolTips as a property of the UI component, with the component deciding when and if to show it. I would like it to force it to be like doing one in javaScript where it was always just like saying "Show it now" "stop showing it now"
Does anyone know about doing this during drag?
Thanks

What you could try is to show the tooltip yourself with the mx.managers.ToolTipManager. Create for example a VBox that implements mx.controls.ToolTip and displays the message you want to show to the user.
You can see a working example at FlexExamples.
Another idea is to show a programmatic mouse cursor when the drop is denied. I've just read an article about that on Inside Ria.
