QUESTION
I'm currently playing around with the new Jetpack compose UI toolkit and I like it a lot. One thing I could not figure out is how to use stickyHeaders
in a LazyColumn
which is populated by the paging library. The non-paging example from the documentation is:
ANSWER
Answered 2021-May-26 at 11:49I got it work by looking into the source code of the items
function: You must not call stickyHeader
within the items
function. No need to modify the PagingData flow at all. Just use peek to get the next item without trigering a reload and then layout it:
QUESTION
I have implemented LazyColumn
with Paging, but I'm now trying to add sticky headers as well.
The stickyHeader()
function is not available inside the items()
scope, so I don't see how this should work.

fun MovieList(movies: Flow>) {
val lazyMovieItems = movies.collectAsLazyPagingItems()
LazyColumn {
val itemCount = lazyMovieItems.itemCount
var lastCharacter: Char? = null
for (index in 0 until itemCount) {
// Gets item without notifying Paging of the item access,
// which would otherwise trigger page loads
val movie = lazyMovieItems.peek(index)
val character = movie?.name?.first()
if (movie !== null && character != lastCharacter) {
stickyHeader(key = character) {
MovieHeader(character)
}
}
item(key = movie?.id) {
// Gets item, triggering page loads if needed
val movieItem = lazyMovieItems.getAsState(index).value
Movie(movieItem)
}
lastCharacter = character
}
}
}

I'm using React, typescript and Material UI. I've created a pretty common "Create user form" with basic inputs for username, name, email, ect. Added two buttons, "Edit" and "Delete." Everything seems to function properly, however, I cannot get this error message resolved.

is likely causing this. Can you try removing it? If you want the table to appear on a Paper component, then try nesting TableContainer under Paper.

Im new to web development and currently developing a webapp for my mothers company. I'm stuck on writing text block above the background image and I'm getting strange top padding in the div. I can't figure out where that comes from so I can remove it and work from there, adding additional padding and applying more css to the .text-block.

I have a dynamic list component in JS. You pass the data array and column headers you want to display and it will create only the column headers you want, then it gets each line of the data[header.columnName] and displays that on each line. I store the headers for different lists in a database so they can be changed on the fly. I am new to angujarJS and angular, so maybe I didn't do it the best way, but it worked pretty cool until I met TypeScript.
I looked at many Pipes examples and (key,object) posts, but I'm not clear on how to make that work on this code. The data is just a list of anything, like locations(locationId, locationName, description, skip1, skip2, etc.) and columnHeaders contains list of columns to display (locationId, locationName) and skips the rest.
...ANSWER
Answered 2021-May-01 at 14:44To be honest, I'm not sure how "let element" works just yet - but I was able to solve the problem. So now in theory I "should" be able to pass a data source and desired columns into a component and reuse it for any list.
QUESTION
Please see below video on what I am trying to achieve, I have a screens with multiple Flatlists with Data and other items, I want each header to stick as users is scrolling through different sections. I have tried using stickyheaders props that comes with React Native flatlist but that only works for one flatlist, I am looking for a solution that takes care of multiple sticky headers.
Thanks
...ANSWER
Answered 2021-Apr-20 at 07:35You have to use single flatlist in a screen to acheive this, there is a ListHeaderComponent and ListFooterComponent in flatlist, you can try adding items in header
ScrollView/Flatlist has a property stickyHeaderIndices, you can give values for example stickyHeaderIndices={[0,3,5]}
in this example scroll, first item will stop, then 3rd then 5,
QUESTION
I have a Layout component, which has a Table component, with a component Entry for each row.
Each row can be selected, so later with a button I can send all the entries to a REST service, so each time a row is selected I add it to my state.
But each time the state changes, my Layout component renders, rendering each entry of the table, that makes me lost lots of performance and time.
Is there a way to avoid rerendering the component? I'm trying to avoid using class components.
This function triggers the rendering...
...ANSWER
Answered 2021-Mar-27 at 09:15If you wrap RACheckEntry
in React.memo
(RACheckEntry =React.memo((props) => {..})
) React will only re-render it when props change, however one of you props is a method checkboxHandler
, I don't see where you define it, but if it is defined inside a functional component, it'll be re-created on each render, making memo
useless. To avoid this problem React provides useCallback
hook, if you define your handler with it it'll stay the same between renders (const checkboxHandler= useCallback(() => { ...},[]
).
Someone had a similar problem with a different table and it seems it work for them react-table is extremely slow with react-select: how to speed it up?
Update: move all manipulations with state inside setSelectedChecks callback, so you don't depend on the current state inside checkBoxHandler

Using ReactJS, I am trying to make a second (smaller) navbar the same way Airtable has done on their product page. My first navbar is at the top, and turns dark from transparent once I scroll. The second bar (colored purple in the screenshot to easily see) is currently behind the first navbar when I would like it to sit right underneath the header background image.
First (main) Navbar - "Header.js"

This is the only solution I have found...
