B4A Library [Class] Flexible Table

klaus · Apr 22, 2022

The Table class needs following libraries:
JavaObject internal
SQL internal
StringUtils internal
ScrollViewd2D additional.
You need to download the ScrollView2D.jar and ScrollView2D.xml files and copy them into the AdditionalLibraries\B4X folder.
Check these libraries in the Libraries Manager tab in the IDE.
For explanations about libraries, you may have a look HERE.

This thread will be used by Erel, Melamoud and myself to discuss / post new releases of the Table class.

The table class is a flexible UI component that enable scrollable table like UI, with sortable columns, multiselect rows etc

the table is very efficient, maintaining labels only for visible rows

old thread with details : http://www.b4x.com/forum/additional...view-supports-tables-any-size.html#post110901

The class depend on following libraries:
- StringUtils (standard)
- SQL (standard)
- JavaObject (standard)
- ScrollView2D (additional)

List of major features.
1. scrollable table UI
2. sortable columns
3. select a row, cell or multi select rows
4. callback for selection / click a cell / row
5. callback for long click action
6. read / write to CSV file

Current version --> 3.30 Custom View
Current version --> 1.44 Class

Other complementary routines:

Load data with the Remote Database Connector.

EDIT: LucaMs has written a routine to fill a table with a Remote Database Connector query result see post 182.
The routine hasn't been added into the Class for the reasons explained in post 183.
A sample program can be found HERE.

Code:

B4X:

'load data from a RDC Request 'Result = DBResult object got from a RDC request 'AutomaticWidths True > set the column widths automaticaly 'Written by LucasMs Public Sub LoadRDCResult(Result As DBResult, AutomaticWidths As Boolean) cAutomaticWidths = AutomaticWidths NumberOfColumns = Result.Columns.Size innerClearAll(NumberOfColumns) Dim Headers(NumberOfColumns) As String Dim ColumnWidths(NumberOfColumns) As Int Dim HeaderWidths(NumberOfColumns) As Int Dim DataWidths(NumberOfColumns) As Int Dim col, row As Int Dim str As String For col = 0 To NumberOfColumns - 1 Headers(col) = Result.Columns.GetKeyAt(col) If AutomaticWidths = False Then ColumnWidths(col) = 130dip HeaderWidths(col) = 130dip DataWidths(col) = 130dip Else HeaderWidths(col) = cvs.MeasureStringWidth(Headers(col), Typeface.DEFAULT, cTextSize) + 8dip + cLineWidth DataWidths(col) = 0 Dim FieldValue As Object For row = 0 To Result.Rows.Size - 1 Dim Record() As Object = Result.Rows.Get(row) FieldValue = Record(col) If GetType(FieldValue) = "java.lang.String" Then DataWidths(col) = Max(DataWidths(col), cvs.MeasureStringWidth(str, Typeface.DEFAULT, cTextSize) + 8dip + cLineWidth) End If Next ColumnWidths(col) = Max(HeaderWidths(col), DataWidths(col)) End If Next SetHeader(Headers) SetColumnsWidths(ColumnWidths) For Each Record() As Object In Result.Rows Dim R(NumberOfColumns) As String Dim FieldV As String For col = 0 To NumberOfColumns - 1 FieldV = Record(col) R(col) = FieldV Next AddRow(R) Next End Sub

This is another routine updated by cimperia in post #392 using a Map for the columns and a List for the rows.

B4X:

'load data from a RDC Request 'A RDC request returns a DBResult object, therefore this method 'could be called as is: 'LoadRDCResult(DBResult.Columns, DBResult.Rows, True) 'AutomaticWidths True > set the column widths automaticaly 'Written by LucasMs Public Sub LoadRDCResult(Columns As Map, Rows As List, AutomaticWidths As Boolean) cAutomaticWidths = AutomaticWidths NumberOfColumns = Columns.Size innerClearAll(NumberOfColumns) Dim Headers(NumberOfColumns) As String Dim ColumnWidths(NumberOfColumns) As Int Dim HeaderWidths(NumberOfColumns) As Int Dim DataWidths(NumberOfColumns) As Int Dim col, row As Int Dim str As String For col = 0 To NumberOfColumns - 1 Headers(col) = Columns.GetKeyAt(col) If AutomaticWidths = False Then ColumnWidths(col) = 130dip HeaderWidths(col) = 130dip DataWidths(col) = 130dip Else HeaderWidths(col) = cvs.MeasureStringWidth(Headers(col), Typeface.DEFAULT, cTextSize) + 8dip + cLineWidth DataWidths(col) = 0 Dim FieldValue As Object For row = 0 To Rows.Size - 1 Dim Record() As Object = Rows.Get(row) FieldValue = Record(col) If GetType(FieldValue) = "java.lang.String" Then DataWidths(col) = Max(DataWidths(col), cvs.MeasureStringWidth(str, Typeface.DEFAULT, cTextSize) + 8dip + cLineWidth) End If Next ColumnWidths(col) = Max(HeaderWidths(col), DataWidths(col)) End If Next SetHeader(Headers) SetColumnsWidths(ColumnWidths) For Each Record() As Object In Rows Dim R(NumberOfColumns) As String Dim FieldV As String For col = 0 To NumberOfColumns - 1 FieldV = Record(col) R(col) = FieldV Next AddRow(R) Next End Sub

Load data from a MSMariaDB database.

Another routine for loading data from a MSMariaDB database can be found in post#727.

'For a Table added in the Designer, this is new
'No need to initialize nor add it onto a parent view

For a Table added in the code:
The Initialize routine has been splittend into two routines.
New:
Initialize (CallBack As Object, EventName As String)
InitializeTable (vNumberOfColumns As Int, cellAlignement As Int, showStatusL As Boolean)
'Example:
Table1.Initialize(Me, "Table1")
Table1.InitializeTable(5, Gravity.CENTER_HORIZONTAL, True)

Old:
Initialize(CallBack As Object, EventName As String, vNumberOfColumns As Int, cellAlignement As Int, showStatusL As Boolean)
Example:
Table1.Initialize(Me, "Table1", 5, Gravity.CENTER_HORIZONTAL, True)

EDIT: 2015.04.29 Version 1.43

Using this class, still on version 2.26 as I made several modifcations of the code.
There is a bug to do with the Sub AddRow that can cause a serious slowdown of loading a large table.

The last few lines of that Sub should be:

B4X:

    If cShowStatusLine Then
        If (lblStatusLine.IsInitialized And enableStatusLineAutoFill) Then setStatusLine(Data.Size & " rows") ' should this be automatic ?
    End If

Omitting: If cShowStatusLine Then
Means the status label is updated for every row of the provided data, even if you don't want the status label, so even if cShowStatusLine = False

Also these lines:

[CODE
SV2.Panel.Height = Data.Size * cRowHeight
SVF.Panel.Height = SV2.Panel.Height
updateIPLocation
[/CODE]

I think, can be taken out of the Sub AddRow and be added instead to the end of the code in ShowRow, with a small performance gain.

Unless I am mistaken the above still applies to the latest version. 3.30.

It is still there.

Have you tested it ?
ShowRow is called many times during scrolling, do you see any scroll performance loss ?
How many rows are you loading ?

Yes, tested and all working fine.
As said, the main thing is to do with cShowStatusLine.

Then I attached my current table class as I have it now and also a sorting class with the sorting algo's.
I do realize that it might be somewhat tricky to convert the sorting code in the latest table class, but I think
it may be worth it.

The posted file Table.bas had faulty code in the 2 Subs that passed a map a B4XOrderedMap to the table class and this has been fixed.
Nil to do with the sorting code, but I thought best to correct it.

How, if possible, to change the name of the column if the table is already initialized?

klaus · Dec 21, 2022

With :

B4X:

Table1.SetHeader(Array As String("Col 1", "Col2", ...))

Sergey_New · Dec 21, 2022

Thank you! The table had a hidden column (width=0), now it has appeared. Is it possible to set this column to its original width=0?

klaus · Dec 21, 2022

Try to hide the column again:

B4X:

Table1.hideCol(2)

Sergey_New · Dec 21, 2022

I have an old version of the table where there is no hideColumn

P.S. Found: hideCol

Need help.
I have many small CSV files.
As there are many, I want to include it in KVS and I would like to know if there is a solution to be able to open it through TableV3_30?
Thanks.

klaus · Jan 1, 2023

Sorry, but i do not really understand your problem.
You have many csv files.
What do you include in KVS ?
I have never used KVS.
What do you mean with: open it through TableV3_30
You can easily read a csv file into a Table CustomView.
Do you want to show several or even many Tables at the same time ?
Depending on the answers to the questions above, the solution could / would be different.
I am afraid that for small csv files, the Table CustomView is too big.
I have CustomViews for Tables with different levels, not yet published, and cross-platform to accomplish what you want.
But i need more detailed information on what exactly you want to do and what you expect.
Can you post a small project showing either what you have already done and what you want to achieve.
Maybe you could have a look at this thread: https://www.b4x.com/android/forum/threads/slow-loading-clv-with-table-solved.144928/page-2#posts

JoséCarlos · Jan 2, 2023

Good Morning.
Thanks for your response.
I have several .csv files.
a.csv, b.csv, c.csv, d.csv............
I stored them all in KeyValueStore:
kvs.Put("a", a.csv)
kvs.Put("b", b.csv)
kvs.Put("c", c.csv)
kvs.Put("d", d.csv).........

In your example in TableV3_30 we used:
Table1.LoadTableFromCSV2(File.DirInternal, "a.csv", True, ";", True) to a.csv
Table1.LoadTableFromCSV2(File.DirInternal, "b.csv", True, ";", True) to b.csv.....

My question can be asked:
kvs.Get("a"), kvs.Get("b"), kvs.Get("c"), kvs.Get("d"),....
Thanks.

klaus · Jan 2, 2023

As i have never used KeyValueStore it is difficult to give a concrete advice.
You say that you have :
I have several .csv files.
a.csv, b.csv, c.csv, d.csv.
What is the content of a.csv, b.csv etc ?
Are these file names or what else.
When you call kvs.Get("a"), what do you get in return ?
