Let me preface this by saying I know this goes against the Android Design Guidelines.
I want to be able to take the built-in navigation tabs for the action bar and move them to the bottom of the screen. I looked through the Javadocs for ActionBar and didn't see any built-in functionality (rightfully so). Does anyone know of some way, perhaps through overriding styles or themes, to achieve this?

I am using MVC for my project. And I have few views in View. However, I want to know how to add a scrollbar to one view and only make that part can be scrolled vertically.
I have tried using CreateWindowW() for adding WM_VSCROLL parameter, but it does not work.
This is a TUI application, so I think the professor try to make us using a cell as bar, so you can scroll the cell up and down
In PreCreateWindow(CREATESTRUCT& cs), set cs.style |= WS_VSCROLL;.
You may have to respond to WM_VSCROLL to process scroll messages.
Sorry for the confusing. I am resisted to use TUI only. And I misunderstood what the professor needed. So he wanted us to move a color cell so you can scroll up and down for checking player's moves. I am making a Gomoku Game by using C++. So I figure it out, right now my move list view can move up and down for viewing full moves. Thanks for all the answers

I want to make my own scrollbars for a custom drawn plot, like this image, what would be the best way to go?
Scrollbars should:
Only be visible when mouse hover over it (with fade in/out)
Be a part of the x/y axis of the plot, like in the picture
Not have any arrow buttons, just the thumb Thinner than the normal scrollbars
Would you suggest to:
Create everything from scratch, handling paging, scrollwheel etc.
Try to inherit CScrollBar and do my own drawing?
From what I've read, it's not very easy to customize scrollbars in MFC, for example here)
First off, these have to be scrollbar (or other) controls, not window scrollbars (used for scrolling a window).
Second, the statement "it's not very easy to customize scrollbars in MFC", is only partially true. MFC is a "thin wrapper" of Windows API, so you should better refer to the documentation of the Windows scrollbar control.
Then there is the CScrollBar class, but took a short look, and indeed, it does not really offer anything more than the Windows scrollbar does. As for the sample in the link you posted is a new (custom) control (painting everything on its own), i.e. literally "from scratch", not inheriting anything from CScrollBar.
So, you have to look into the Windows scrollbar control, and what it offers. Did take a look, and saw few things. Unfortunately there seems to be no owner-draw functionality. You can process the WM_CTLCOLORSCROLLBAR message, but this only allows you to change colors.
And according to the documentation the background color only. This appears to be the only possible customization, apart from the SBM_ENABLE_ARROWS message, which can hide the arrows. And no fading effect. If these are enough to you, you could try the Windows/MFC scrollbar, otherwise try writing your own.
I have implemented an ActionBar with my own custom icons. I have added tabs as well but I want these to appear below the ActionBar. At the moment they are displaying in the ActionBar. According to the Android Developers guide:
http://developer.android.com/guide/topics/ui/actionbar.html
when the screen is wide enough the tabs appear in the action bar
alongside the action buttons (such as when on a tablet, shown in
figure 7), while when on a narrow screen they appear in a separate bar
(known as the "stacked action bar", shown in figure 8)
Is it possible to implement a stacked action bar permanently so that the tabs are constantly displayed below the ActionBar across all devices?
If you want the same effect as in that image, you can use tabs. Here is a tutorial on how to implement them.
I have a member of CWnd class name mywindow
and i want to add to it a scroll-bar.
how i can do it?
i try already to do:
mywindow.EnableScrollBarCtrl(SB_BOTH,TRUE);
it display both Horizontal and Vertical scroll-bars,
but i cannot push the buttons or move the scroll-bars.
i try also after the first command:
mywindow.EnableScrollBar(SB_BOTH,ESB_ENABLE_BOTH);
and it change nothing.
can someone could show me a simple example how to add scroll-bar to this member?
thanks a lot,
Tal
Enabling the scroll bars isn't enough. You have to react to the window messages WM_HSCROLLand WM_VSCROLL. Using the GetScrollInfo method you get the position (value) of the scroll bars and then you draw your window content according to this position.
Look up some scroll bar tutorials such as http://www.codeproject.com/KB/dialog/scrolling_support.aspx . In essence, dwo's comment above is what you need to do - handle those messages and set the virtual client area size.
There must be some 'overflow' before scroll bars became active.
Write some 'sufficiently long' data in your view and the scrollbars will become active (at least, that was my experience time ago).
Usually scroll bars get handled 'automatically' from MFC components like (for instance) text editor or form view. I.e. will became visible when needed also without explicit call EnableScrollBarCtrl ...
Is there a way to change the alignment of the icon or text of a tab in Qt? Specifically, I would like the text to appear below the icon. By default the icon sits to the left of the text, but that's not appropriate for all situations (especially when you start styling your tabs with stylesheets) It would seem very odd to me that this aspect would be so restricted when I can completely alter the look and feel of the rest of the tab.
Thanks for any suggestions!
The only way I can see is to create a subclass of QTabBar that implements your own painting algorithm. Then you'd need to subclass QTabWidget to set your own version of the tab bar. It doesn't look like a lot of fun to me.
