B4A Library SD: MenuExtender

Star-Dust · Jan 30, 2018

I created a new library that adds new menus that are not in my other libraries. (menu and PanelExtra)
The sources are written exclusively in B4A

ManagerPanel: This class has been transferred to the PanelExtra Library

Catalog: It has a series of articles with relative photos, name, code, description and price in grid format.
Clicking the article opens at full schemro to the card and you can buy it or go back.
Clicking the purchase button (the shopping cart) generates the Select event
ATTENTION: This library intercepts the back key to return

Really nice work....
can add images direct from a url ????

Thank you. I see if I can add it to the next update.

Clearly if I have to download from the Internet 10 (or even 100) images, it may require a substantial amount of time before the interface appears

Yes, of course... can do load image in a groups 20 o 30 and when move the scrollview, continue loading.... is only a idea
i think really nice library

Update to version 0.12

setImage (ID As String, Image As Bitmap)

use:

B4X:

For I=1 To 18
    ' Not set Image - Null
    catalog1.Add(I,Null,"Element " & I, "Code: " & I ,"Description " & I,"€. " )
Next
 
'Set image after
For I=1 To 18
    catalog1.setImage(I, LoadBitmap(File.DirAssets,filename(I)))
Next

Download Image from internet:

B4X:

For I=1 To 18
    catalog1.Add(I,Null,"Element " & I, "Code: " & I ,"Description " & I,"€. " )
Next

For I=1 To 18
    Dim j As HttpJob
    j.Initialize("", Me)
    j.Download(Link(i))
    Wait For (j) JobDone(j As HttpJob)
 
    If j.Success Then
        catalog1.setImage(I, j.GetBitmap)
    End If
    j.Release
Next

Note: ManagerPanel has been transferred to the PanelExtra Library

B4X:

    Dim files As List
    files = File.ListFiles(File.DirRootExternal & "/Fotos")
    If files.Size = 0 Then
        ToastMessageShow("No se ha encontrado imagenes " & CRLF & File.DirRootExternal    & "/Fotos", True)
    Else
        For i = 0 To files.Size - 1
            catalog1.Add(I,LoadBitmap(File.DirRootExternal & "/Fotos",files.Get(I)),"Nombre" & I,"€. " & Rnd(1,4) & "." & Rnd(10,99),"AAA","2.000")
        Next
    End If

This is the code that I use. The problem is that my computer is slow when loading the application, which could be the problem so that it does not behave so slowly?
Thanks and blessings!!!

Unfortunately it is not possible to speed it up, because this library is produced entirely in B4A and therefore is slower than those made entirely in Java.

More often it is designed to divide the various choices in the catalog.
In the first catalog should open photos and categories, clicking the category the catalog will be repopulated with the content of that category.

I do not know if it is suitable to use it for a ListFile, it is more suitable to create an App for the sale of products, similar to EBAY or to create a catalog of products of a company.

¿Qué me será útil para hacer algo similar pero con álbumes de fotos?
¡Gracias!

Star-Dust · Mar 21, 2018

If the photos are many it is better to use CustomListView, xCustomListView and UltimateListView. They are the fastest and most suitable for managing lots of data quickly.
If the images are less than 50, my Catalog can be fine and do not slow down.

Of course, an old device is slower ... A new device with my library is also fine with heavy DataBase.

Excellent thanks!!!

Version 0.13 released

Now allows multiple selection.
The examples have been updated, WARNING: The Select event now restores Array.

BluSky76 · Jan 13, 2020

[CODICE = b4x] catalog1.Add (I, Null, "Element Name Product Line1" & I, "Code:" & I, "Description" & I, "€.") [/ CODE]

The written "Element Name Product Line 1" is not displayed correctly but is cut off. You can increase the height of the Element field

Thanks
