B4J Question B4XTable "go to last"

LucaMs · Oct 30, 2022

I fill a B4XTable with 100 "records" (I'm attaching a test project, in which they are not DB records), 10 records / page.
If I press ">", next page to the end, everything is ok and the navigation keys for subsequent records are correctly disabled.

If on the first "page" I press on "> |", last page, the B4XTable shows me an enon-existent eleventh page, with the hundredth "record".

Tip:
1. Make the table anchored to all sides.
2. Set the minimum width instead of the size of each column:

B4X:

xTable.MinimumWidth = 40
For i = 0 To 6
    xTable.AddColumn("COL" & i, xTable.COLUMN_TYPE_NUMBERS)
Next

3. It is indeed a bug. I'll release a fix...

It was just a demonstration

B4XTable lblLast_Click add mCurrentCount Mod mRowsPerPage = 0 test

B4X:

Private Sub lblLast_Click
    If lblLast.Tag = False Then Return
    If mCurrentCount Mod mRowsPerPage = 0 Then
        setFirstRowIndex(mCurrentCount - mRowsPerPage)
        Return
    End If
    setFirstRowIndex (Floor(mCurrentCount /  mRowsPerPage) * mRowsPerPage)
End Sub

This is the updated code:

B4X:

Private Sub lblLast_Click
    If lblLast.Tag = False Then Return
    Dim NumberOfPages As Int = Ceil(mCurrentCount / mRowsPerPage)
    setFirstRowIndex ((NumberOfPages - 1) * mRowsPerPage)
End Sub

I could not understand why the project (a test) attached to the first post and that I am attaching here, continues to not work as it should.
I also attach the same project but with the source of the B4XLib and this one works!

Maybe your internal b4xtable.b4xlib doesn't be updated.
I have tested 2 projects you posted, Both of them work, if you replace b4xtable.bas from works.zip in your b4xtable.b4xlib.

I had put the new library among the additional ones but there is an older copy in the internal ones.
Now it's ok, thanks.
