layouts | HID layouts for various locales and keyboards | Keyboard library

Try running the following commands on your local machine:

If you want to make a registration system I recommend php

So Qt doesn't offer this, but you can ask your OS to do it for you.

Assuming you're just looking at Windows, you can change the current keyboard layout in python using pywin32, which lets you easily access the Windows API from your script. Once installed into your Python environment you can import win32api and then use a call like win32api.LoadKeyboardLayout('00000809',1) to set the layout (the values I've put here set it to UK English). The first parameter is a string representing the keyboard layout to use, and the second is a flag. See documentation.

I found this list of KLIDs (Keyboard Layout IDs), which shows two for Tamil keyboards. "00000449" is Tamil, "00020449" is Tamil 99. The 449 at the end means Tamil, and the two digits before set which subtype of Tamil keyboard to use (e.g. 20 for Tamil 99) - I can't find one for Tamil phonetic, but maybe you'll be able to find it.

You can set up your program to call these functions whenever you want it to switch keyboard (for example, when your user activates a specific text input box).

Also, if you want to check the current keyboard layout you can use win32api.GetKeyboardLayout(0) (doc). Maybe you can use this to figure out what the IDs are for each of the Tamil keyboards you want to use. Mind that it returns an int for the locale id rather than a string.

Other useful keyboard related functions are win32api.GetKeyboardLayoutList() (to find all the locales installed on the current machine), win32api.GetKeyboardLayoutName() and win32api.GetKeyboardState - documentation for all these can be found here.

It appears you are using react-router-dom@6 so there are no longer any route props. In other words, props.match is undefined. Reading into props.match.params then throws the error.

Use the useParams hook to access the date route param.

According to the language reference, chapter 3 "Data model" (see here):

An object’s type determines the operations that the object supports (e.g., “does it have a length?”) and also defines the possible values for objects of that type. The type() function returns an object’s type (which is an object itself). Like its identity, an object’s type is also unchangeable.[1]

which, to my mind states that the type must never change, and changing it would be illegal as it would break the language specification. The footnote however states that

[1] It is possible in some cases to change an object’s type, under certain controlled conditions. It generally isn’t a good idea though, since it can lead to some very strange behaviour if it is handled incorrectly.

I don't know of any method to change the type of an object from within python itself, so the "possible" may indeed refer to the CPython function.

As far as I can see a PyObject is defined internally as a

You can use LocalContext to get activity, and it has a window on which you can apply needed flags.

In such cases, when you need to run some code on both view appearance and disappearance, DisposableEffect can be used:

It's supposed to re-measure a component based on another component size...

SubcomposeLayout doesn't remeasure. It allows deferring the composition and measure of content until its constraints from its parent are known and some its content can be measured, the results from which and can be passed as a parameter to the deferred content. The above example calculates the maximum size of the content generated by mainContent and passes it as a parameter to deferredContent. It then measures deferredContent and places both mainContent and deferredContent on top of each other.

The simplest example of how to use SubcomposeLayout is BoxWithConstraints that just passes the constraints it receives from its parent directly to its content. The constraints of the box are not known until the siblings of the box have been measured by the parent which occurs during layout so the composition of content is deferred until layout.

Similarly, for the example above, the maxSize of mainContent is not known until layout so deferredContent is called in layout once maxSize is calculated. It always places deferredContent on top of mainContent so it is assumed that deferredContent uses maxSize in some way to avoid obscuring the content generated by mainContent. Probably not the best design for a composable but the composable was intended to be illustrative not useful itself.

Note that subcompose can be called multiple times in the layout block. This is, for example, what happens in LazyRow. The slotId allows SubcomposeLayout to track and manage the compositions created by calling subcompose. For example, if you are generating the content from an array you might want use the index of the array as its slotId allowing SubcomposeLayout to determine which subcompose generated last time should be used to during recomposition. Also, if a slotid is not used any more, SubcomposeLayout will dispose its corresponding composition.

As for where the slotId goes, that is up to the caller of SubcomposeLayout. If the content needs it, pass it as a parameter. The above example doesn't need it as the slotId is always the same for deferredContent so it doesn't need to go anywhere.
