Is this possible to have vertically expanded nav (menu with drop down) in mobile version of top bar instead of the default one (sliding in and out with back button)?
This could be accomplished by overriding the top bar methods, but maybe there is some other / simpler way...

I have RadioGroup with many buttons. Now when I add an item, they become smaller and smaller. How is it possible to make them scrollable?
TRadioGroup does not natively support scrolling. However, what you can do instead is the following:
place a TGroupBox on your UI.
place a TScrollBox onto the TGroupBox, set its Align property to alClient, and its BorderStyle property to bsNone.
place a TRadioGroup onto the TScrollBox, clear its Caption property, and set its Left property to -2 and its Top property to -15 (or whatever the TRadioGroup.Font is set to plus a few extra pixels). This positioning is needed because you cannot turn off the TRadioGroup's borders or the space reserved for its Caption.
Tweak the TScrollBox.HorzScrollBar.Range and TScrollBox.VertScrollBar.Range properties so they do not scroll far enough to see the TRadioGroup's right and bottom borders.
This way, the buttons appear as if they are part of the TGroupBox, but with the added scrollbar(s).
RadioGroup->Items->Count
TRadioGroup component doesn't have an embedded scrollbar, but you can put the radio group on a TScrollBox for a similar effect.
You can use the Buttons collection to refer each button, e.g.
RadioGroup->Buttons[0]->Height = 5;
RadioGroup->Buttons[1]->Top = RadioGroup->Buttons[0]->Top + 10;
Anyway a TComboBox could also be a good choice.
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 would like to display the ActionBar alone without any navigation buttons(Home, back,etc) which are present at the bottom of the screen.
If I use '#android:style/Theme.NoTitleBar.Fullscreen', then even the ActionBar is not present.
Is there a way to display ONLY the ACTIONBAR without the navigation bar at the bottom?
For hiding the Navigation Bar, which is there only since API 14, see this
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 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 ...
