B4J Library [B4X] [XUI] SD FlexGrid (Table)

I created a new library to show a table (or grid) similar to the one in EXCEL.

There are already excellent classes that allow many to accomplish things, such as xCustomListView by @Erel (B4X) and with the FlexibleTable by @klaus (B4A)

I wanted to make something slightly different suited to my needs.

Explanations:
  1. To get the calculation of the cells that contain a formula I have added Erel's B4XEval to my Library, but as soon as possible I will make it external so that everyone can modify it according to their needs.
  2. To select multiple cells, position yourself on the first cell of those to be selected (the one at the top left) click a shot and then click again and drag your finger to cover all the cells (or area) that you want to select
  3. It is still in beta version, presents problems in large grids.
  4. Now only for B4A and B4i

You have to copy the XUI libs to the corresponding folders, and select it in the libs tab

Hallo cableguy,
The Jxui lib is a intern lib und come with the Installation.
The jxui lib is in the internal lib folder and jxui is selected in the libs tab.
Die error Log say " Cannot find: D:\PRG\B4J 7.00\B4J\libraries\xui.jar"
The xui.jar is the Name of the B4A xui lib.

I'm sorry, but as you have observed from the files I have not released the version for B4J yet, but only B4A and B4i.
You are using the Android version on B4J

Also, as stated In the release thread, this lib is BETA so it is not unusual for it to be... Not complete(ly) XUI

Why not!? @Erel has realeased XUI libs that only target B4J and B4A, not b4i... He does however need to make this CLEAR in the release thread!
True, for example, the B4X libraries were announced only for B4A and B4J but only after a few weeks we were able to use them in B4i. But the thread was marked B4X.

There are other examples in this regard, but I do not want to prolong and i want to avoid controversy. I prefer to remove B4X and put it back when I add the B4J version.

As I see it, it is completely fine to mark a thread with [B4X] even if it only supports two platforms. You should explain it in the library instructions.

[B4X] tag is important as the search engine treats such threads as multiplatform.
