I built a cross platform application to run it on Android. I use a TEdit to get the numbers and a Label to show the result of the calculation.
(This function is already running).
Is there any way to show a calculator keyboard whenever I click into to an TEdit object?
It shouldnt just pop-up like a second form I built in.
Set the TEdit.KeyboardType property to either TVirtualKeyboardType.NumbersAndPunctuation or TVirtualKeyboardType.NumberPad as needed. When the user gives focus to the TEdit, it will display the OS's standard virtual keyboard in the appropriate layout.

I have a multi-monitor config that duplicates the task bar on each monitor. I also have an application with an icon in the taskbar (thus it shows on all monitors), and I'd like this application to behave differently depending on which monitor the click came from.
Is it possible to determine which monitor's taskbar was used to launch that app? I would just need the API function names (rather than actual code).
Thanks!
Whether or not what I asked in my OP is possible, I found a way to do what I want: Immediately upon launch, I obtain the current mouse position in absolute coordinates. This allows me to determine which monitor the mouse is on, which is almost certainly the monitor holding the taskbar icon used to launch the application.
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 have a laptop connected to an external monitor. Need to do a presentation where I have Powerpoint open on one screen and Excel on another screen and toggle the external screen
So: the laptop screen should always show Excel but the external screen should show either PP or Excel.
I put display into extended mode, put PP on a second screen. so far so good. But then I need to switch external screen to Excel. If I change to Duplicate mode, my PP moves to the main screen and I cannot switch easily back.
Is there a way to quickly and easy switch only the external monitor between main and extended screens?
You need to be on Extended Mode always. Based on your requirement, you can manually drag the respective Application (in your case Excel/PowerPoint) to whichever screen you want.
You also can tweak the PowerPoint Slide Show setting to define which monitor to use and also whether to use Presenter View or not (refer screenshot)
Hope this helps!
On my arm embedded device with a touchscreen, I have a 3rd party program (program A), that creates a window which handle keyboard presses. Because of that, this window always has to have focus. This is a closed source, and I do not have options to modify it.
I need to create a window in linux, that never grabs focus. It just shows an image, some times full screen. However, I have options not to make it full screen (1 pixel less, so window below is visible.).
Right now, I am using only X server, but I can install (almost) any window manager.
Is there a way to create a window in X, that never gets focus? If I understand X correctly, a window bellow mouse will get focus.
Is there a window manager, which supports such feature?
Is this possible to do with with xcb or wayland?
On Wayland, it's up to the compositor to tell the client whether it has focus or not, and which surface(s) to send key events to. So it would depend on the compositor or compositor toolkit you're using if it's possible.
KWin has an option that sounds like it does what you want. Right click the window title bar and choose more actions -> special window settings -> accept focus
Of the compositor toolkits, I only know the Qt Wayland Compositor API, and with that it should be possible (assuming your application can run as a Wayland client). The easiest thing would be to just show the image in the compositor using the QML APIs, or you could set enabled: false on the WaylandQuickItem or ShellSurfaceItem that you don't want to grab input focus.
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.
