B4J Question [B4X] CustomListView with X Columns based on width of Form/Screen ?

[Magma]

Let's say for example we have a card (a layout like this):

a pane... with some labels... may be a an image too....

Is there something (CustomListView) ready to use or I must create it... to show many layouts with X Columns based on width of Form/Screen ?

or if it is bigger form... screen:

I know that i can may be create 2,3,4 different layouts with 2,3,4 panes and labels...
but thought may be there is a ready routine for customlistview making that...

or not ?

is there a ready lib/snippet .. that can i use... ? thanks

... It's a bit slow with loading layout everytime and various controls into it... but ofcourse doing the job...

adding an example with loading layout.... for anyone want to use it like this

Hmmm I am thinking, add arrows for changing pages (because i want to use it for showing records from databases like different view <> b4xtable)... or something like lazy loading... like customview... but I am on thinking...

ps: have in mind that using scrollpane was original idea by: stevel05 here - so thanks/like must go to stevel05

It is considerably quicker if you don't load a layout.

I don't know why the first answer was not enough:

Send me one of the many credit cards you have, together with the code to use it, without spending limit and I'll write you how to do it ?

(create the item at runtime)

1. on MainForm_Resize
2. (CLV anchored)
3. clear CLV
4. create a panel (pnlItem) as large as the CLV
5. calculate how many cards (CardsPerRow) can fit (horizontally)
6. create CardsPerRow cards (panels) and add them to pnlItem
7. add pnlItem to CLV.

Of course, you should also calculate how many pnlItem (items) would be needed.

...is a way too... a little more complex (as we said) as you must add also an extra pnlitem per row... but ofcourse will have the feature of lazy loading...

?

...the attached file has the same files with that i ve already uploaded (or not?)... did you want to upload something different ?

It is the usual way to create items for CLVs, as per your initial question, with the difference that it is usually more convenient to load a layout into the panel.

Being a CLV you also have other advantages of this View, of course, such as the item-row index (but maybe you won't need this).

Yes I meant to upload this one.

@stevel05 on the fly.... hope you didn't lose a lot of time ! Great work...as always

 

[stevel05]

hope you didn't lose a lot of time

No, it was an interesting distraction

Hey there, I have used scrollpane to solve some like this
