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,

How to access QTabWidget tab editor in Qt Designer - when I double click object name dialog pops up

I have a QTabWidget and I want to add/remove/rename individual tabs. Some sources claim that you can double click it to get a tab editor. When I double click it, I get the "Object name" popup:
I need a similar editor like the one used for comboboxes:
I also tried to edit tab properties by right-clicking it in object tree. The menu is pretty stripped of any useful options:
How to manage tabs? Is it possible without XML editor? If yes how do I
... delete tabs?
... add tabs?
... rename tabs?
... change tab layout?
Just to make it more clear...
Add tab to QTabWidget:
From QTabWidget context menu → InsertPage:
Rename tab in QTabWidget
Select the tab to rename by clicking on it. Then edit QTabWidget property currentTabText in the property editor:
Delete tab in QTabWidget
Select the tab you want to delete. From QTabWidget context menu → Page X of Y → delete:
You should just work with each tab as with a normal widget on screen, without double click. To switch between tabs just click on them, for stacked widget there are two small arrows in the top right corner to switch between pages.
To delete tabs right-click then use 'Insert page', or choose page sub-menu where you can delete or rename page.
You can just drag tabs using header to change the order.
Above 'Insert page' there is a menu item 'Page N of M' (which is currently selected page), in there you will find an item - 'Remove page'

Hide Tab in ViewNavigator in Flex/Flash Builder?

I want to hide a Tab in ViewNavigator, is this possible?
The thing is I want to have a View and a ViewNavigator, but I don't want to have the View as a Tab in the Navigator.
In other words I want to have a View that the user cannot reach from the Tabs in the Navigator. Simply a View/ViewNavigator without being a Tab in the menu.
Is this possible?
Just set visible=false and includeInLayout=false on your Tab.
