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.

WARNING
The use of libraries for personal and / or commercial use is permitted. It is not allowed to modify the sources or change the name of the library. Reverse engineering is not authorized to access the sources for any reason, not even for study or learning reasons.

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 Now for B4A,B4i,B4j
  5. In the example to select a group of cells just long click on a cell (not checkbox). In the case of B4J click with the right mouse button

Hello. My B4A test is invalid, please help me to see how to modify it.

You just need to add a little pause after populating the grid.

You find it in the original example. If you heavily populate a grid, he waits half a second before updating the views so that he doesn't have to continually update
B4X: 
    Activity.LoadLayout("Layout1")
    Ev.Initialize(FlexGrid1)
    FlexGrid1.ColsName=Array As String("","N","On","Name","Img","Digit")
    FlexGrid1.ColsWidth=Array As Int(75dip,50dip,50dip,100dip,60dip,100dip)
    FlexGrid1.ColsType=Array As Int(FlexGrid1.TypeButton,FlexGrid1.TypeInt,FlexGrid1.TypeCheck,FlexGrid1.TypeString,FlexGrid1.TypeImage,FlexGrid1.TypeFloat)
    FlexGrid1.ColsAlignment=Array As String("CENTER","CENTER","CENTER","LEFT","LEFT","RIGHT")
    
    FlexGrid1.SetColCustomize(0,0xFF5BC17D,xui.Color_RGB(240,240,240),xui.CreateDefaultFont(14))
    FlexGrid1.ActiveCheckBox=False
    
    Dim B As Boolean=False
    For i=1 To 100
        B=Not(B)
        FlexGrid1.AddRow(Array As Object("B" &i,i,B,"User " & i,Null,Rnd(50,10000)/100),True)
    Next
    
    Sleep(500) ' Add Pause'
    FlexGrid1.ScrollToRow=FlexGrid1.RowCount

Hello, Star-Dust! Your FlexGrid is very usable. From ver 0.07 char sequenses are supported.
But 2 small thinks are missing...;) :
1. Not supported clickable words by csbuilder in the cells
2. I can't clear selection for cells, something like this:
B4X: 
UnselectCell(Row,Col)

May be it's possible to do by another way?

FlexGrid Example is not responding. Do you want to close it?
This msgbox appears as soon as I click on a checkbox in the list.
I click on it, it removes the tick, but from that moment on it no longer responds to commands (scrolling, etc.) and after 3-4 seconds the message appears.
Can you tell me why? Or check if it's just my problem?
The only thing I have changed (for testing purposes) is to set the column width "Name" to 400

B4X: 
FlexGrid1.ColsWidth=Array As Int(75dip,50dip,50dip,400dip,60dip,100dip)

FlexGrid Example non risponde. Vuoi chiuderla?
Mi appare questa msgbox appena clicco su un checkbox della lista.
Ci clicco, mi toglie la spunta, ma da quel momento in poi non risponde piu ai comandi (scorrimento ecc) e dopo 3 4 secondi appare il messaggio
Puoi dirmi perchè? O controllare se è un problema solo mio?
L'unica cosa che ho cambiato(per fare delle prove) è mettere la larghezza colonna "Name" a 400

B4X: 
FlexGrid1.ColsWidth=Array As Int(75dip,50dip,50dip,400dip,60dip,100dip)

I'll do some tests.
Please use the English language in this forum space

I take this opportunity to report this other little bug to you too (unfortunately I am only suffering from it now ..) Intellisense suggests using the "SetCellValue" method incorrectly (I assume it used to be a property ..)

thanks a lot.
Other two questions
1) If I want to change only the text color of a cell, leaving everything else unchanged (backgrund color, font type and size, etc.) it is possible to do ?
example
B4X: 
FlexGrid1.SetCellCustomize (r, c, xui.Color_Blue, xui.Color_Yellow, xui.CreateDefaultBoldFont (16))
'suppose I only want to change xui.Color_Blue to xui.Color_Green, do I have to rewrite the whole statement with all parameters which will not be touched?
Or I can do something like
B4X: 
CellTetxtColor (r, c) = xui.Color_Green

2) How do I access the font type and size of a given cell?
