Mac supports these sort of views:
https://developer.apple.com/design/human-interface-guidelines/macos/windows-and-views/popovers/
They are like short-lived tool panels but automatically disappear when you click outside the view.
I am trying to figure out if we can utilise them from a cross-platform Mac/Win application but can't be sure if WinAPI or Qt supports something like this? Does anyone know what classes they might be?

I like the new tab interface displayed in the Lion “About This Mac” window. It's not gorgeous, but I think it's extremely useful in presenting information where icons would most probably fail to do a good job.
Question is: is that UI available from standard Cocoa components? I.e., can something similar to it be built with Xcode, without resorting to custom classes with custom drawing code?
Isn't that just a toolbar without images?
Several iLife '11 applications on the Mac use iOS-style black toolbars. For instance, the toolbar at the bottom of this screenshot of iPhoto:
(source: pocket-lint.com)
This sort of look is available in the iOS SDK as "UITabBar."
I am wondering if there is an easy way to achieve this in my ordinary, non-iOS Mac application. If not, what would be the best way to go about creating this effect?
There's nothing that will give you this view out of the box. You'll need to build it yourself.
The simplest method would be to create a custom view with a gradient background and place monochrome buttons in it.
Better would be to create a set of classes similar to NSToolBar that handle positioning, highlighting etc. Even better, build it and then open-source it :-)
However, you'll have to build it yourself. Apart from NSButton there's not much that will help in the pre-existing objects.
I need to display a full screen DirectX window from a Qt app.
Although directX isn't supported directly anymore by Qt this should be easy enough - just override QWidget, provide your own paintEvent() and set a WA_PaintOnScreen attribute.
But when the app is full screen DirectX is grabbing all the mouse and keyboard inputs - so the only way out of the app is ctrl-alt-del.
ps. Even if I wrote DirectX keyboard handlers I would still have to find a way of creating the correct Qkeypress event to pass to Qt.
Has anyone done this? Or is there a simple way to tell DirectX not to grab the keyboard?
To my knowledge Direct3D does not get the keyboard. Your problem more likely arises from the fact that Direct3D in full-screen is quite a different beast. Things like GDI (which Qt may well use to do rendering) do not work by default, the run-time hooks lots of bits of information. That info then, presumably, never manages to get to Qt. The options you have are to re-implement Qt to render using Direct3D (Lighthouse project?) or to use a pseudo full screen. This is usually done by creating a window that has a client area the same size as the screen and then positioning it correctly.
The latter would probably be the simplest solution ...
There was an attempt to get a D3DWidget kind of thing in Qt 4.3-4.5 or something like that, but it never was stabilized or approved and later even removed.
Perhaps indeed lighthouse is an option (with a medium sized amount of work, basically links OS/DX stuff to Qt stuff) or you can take a look at the old direct3D code in older Qt branches. I never used it, and it probably isn't intended to use with recent versions of Qt, but it's better than nothing.
I'm new to cocoa app dev, and I'm searching a solution to create a windows like the tweetie main windows with a left tool bar and a panel that point to the selected icon.
like this screenshot : http://i.stack.imgur.com/qvxWu.jpg
could anyone help me?
It's likely that a lot of the Tweetie UI is implemented using custom controls. You'll want to look into subclassing NSView and how to handle drawing and mouse events. There's nothing built into the Cocoa framework for this.
The NSView documentation has info on view programming, drawing, and event handling. If you're new to Cocoa, you may want to start off with something built in, though, as this will be a lot of work (and requires a pretty good understanding of how the framework works).
I want to build a desktop app where the size of both the window and the content is resized automaticly according to the resolution of the monitor. I know it can be done easily with the docking features of .NET Forms, but my customer insists on going with Linux so I can't use it.
I tried Flex & Air, but the content is not resized automaticaly when I put the app in fullscreen or in another resolution (the app goes full screen but I still have tiny buttons). Now, I am looking at Qt and Gtk...
Is there a GUI framework that can do that? I don't care about the programming language.
Also, since the app will go in a bar it would be nice to be able to customize easily the skin. (like in Flex, WPF, etc.)

An excellent place to start is understanding how the Screen class works: MSDN Even though that is .Net, it will give you an idea of how the screen size, dpi, etc. can be obtained. In addition that information should translate to the Mono platform. Since your client is insisting on Linux, you should look at MonoDevelop and then possibly the GTK# framework. My understanding is that GTK# is not a very friendly (that is pretty) development system (yet).
