I don't have Qt Creator. I'm looking for a solution within Qt Designer to add a button to the form so that if the user presses it, an image appears/disappears, or an image moves from one position to another.
Thanks

I'm laying out UI on a storyboard using the new, controversial library button which has been moved up.
This is driving me crazy - I want to be able to "PIN" this window to a secondary monitor so I can always see available components as opposing to having to click that button every single time I need an element. Currently it disappears, even on secondary monitor once I shift focus to the view controller on screen.
How do I pin the UI Elements library to be able to always see it ?
You can press the option button in keyboard and click in the library window, it's will hold

I am working on Linux Operating System. I want to display a dialog box on an item selection from a drop down menu implemented in ncurses, but the problem is that the dialog box fills up the screen with blue background and further nothing can be done.So, is there a way to display ncurses dialog box inside current window preserving existing ncurses components?
Thanks in advance.
You might use CDK (Curses development kit) to the create dialog box. It provides many other widgets that you can use such as,
Alphalist
Button
Buttonbox
Calendar
Entry Field
File Viewer
Floating Scale
Floating Slider
Graph
Histogram etc...

I have a MFC dialog based application. User can change the language of the dialog, and I made this by closing existing dialog, and opening another with changed language. The problem is that the effect in the taskbar is that one icon is removed, and another identical is created in its place. If my application's icon is not the last icon in the task bar it will be perceived as it was moved to the end of taskbar icon set.
I want to retain icon's position in the taskbar, and rather to prevent icon flicker at all from happening. How do I do that?
The application must support OS'es from Windows XP to Windows 7.
EDIT: alternative question for which I would accept an answer is how to create an invisible window that is nevertheless shown in the taskbar, and how to forward relevant window messages from that window to my main window?
Make the dialog a child of another outer parent window. The parent can be a dialog or any other kind of window; all it will be providing is the title bar. If the user tries to resize it it will have to forward resizing commands to the dialog, but otherwise you shouldn't need to do much in the parent window.
Why not replace the dialog with a CFormView instead? That way there's a frame window that wraps around the dialog (which is embedded in a form view) and it's the frame window that owns the taskbar icon.
Create an SDI application that displays a CFormView. Display the dialog in the default language (or whatever langauge the user previously chose) on initialization. When the user chooses the 'change language' option, simply change the form view that's being displayed with a new one.
Bonus feature: with this design, the framework will take care of things like language-specific accelerators and menus for you with no effort on your part.

I am new commer to IPhone and developed an app "display next and previous image on button click in single view based application".i want, on run my app"one start button and welcome message view" and then clicking on start button, want to move on my already developed application what i have made with Next and Back Button which are showing the next and previous images properly. Also i want, on button click (start), automatically images moves next without
clicking on Next images after some interval of time(5 sec) so that user may use the manually to move from one image to another or automatically after some interval of time.
Thanks in advance to all of you.
I don't undertand what your are saying with "on my already developed app". I you want to move between views avoid Sin
I recommend you to check UIScrollView reference guide and check the Sample Code that Apple provides.
UIScrollView Class Reference
To move between imagen using non gesture detections you can also perform some animations using
UIView animations on the IBAction of the buttons.
I'm sure that if take a look around at apples samples and guides you will develop the app so fast.
I'm trying to figure out a way of using Qt Designer to make a dynamic GUI. For example, let's say I have a main window with a horizontal layout. I have a push button on one side and an empty area on the other. When I click the button the empty area will be filled with a widget that I've made in Qt Designer. When the button is pressed again the widget will be replaced with another widget that I've made in Qt Designer. Would I have to go about making all my widgets, to fill the empty area, custom widgets?
I've tried setting the parent to the empty are, but on the second change I get this
QLayout: Attempting to add QLayout "" to QWidget "t2", which already has a layout
So then I tried deleting the layout but still see the old widget underneath the new one and the layout is now messed up.
help please
Never mind, figured it out. Simple really. Use QStackedWidget and as for the UIs made in Qt Designer wrap that in a class that inherits from QWidget.
