Table - MouseDown event and more

[Erel]

Using the new Door library it is now possible to improve the Table control.
With the following code you can add a new event, the MouseDown event.
The HitTest sub will return the pressed row and column (along with the control's part type).

With this sub you can find the index of the first visible row (this issue was discussed several times in the forum).

You should include the door library: http://www.b4x.com/forum/showthread.php?t=2038

The code is attached.

Sub Globals
    
End Sub

Sub App_Start
    Form1.Show
    obj.New1(true)
    o.New1(false)
    table1.AddCol(cstring,"c1",50)
    table1.AddCol(cstring,"c2",50)
    table1.AddCol(cstring,"c3",50)
    For i = 1 To 10
        table1.AddRow(i,i,i)
    Next
    SetAlternateRowsColor("Table1",cSilver)
    AddMouseDownEvent("Table1")
    HitTest("Table1",35,30)
End Sub

Sub AddMouseDownEvent(TableName)
    obj.FromControl(TableName)
    event.New1(obj.Value,"MouseDown")
End Sub
Sub event_NewEvent
    o.Value = event.Data
    HitTest("Table1",o.GetProperty("X"),o.GetProperty("Y"))
End Sub
Sub HitTest(TableName,x,y)
    obj.FromControl(TableName)
    o.Value = obj.RunMethod3("HitTest",x,"System.Int32",y,"System.Int32")
    
    ListBox1.Clear
    ListBox1.Add("X: " & x & " Y: " & y)
    ListBox1.Add("Row: " & o.GetProperty("Row"))
    ListBox1.Add("Column: " & o.GetProperty("Column"))
    ListBox1.Add("Type: " & o.GetProperty("Type"))
End Sub

Sub SetAlternateRowsColor (TableName,Color)
    If CPPC Then Return 'devices do not support this method
    obj.FromControl(TableName)
    o.CreateNew("System.Drawing.Color" & o.System_Drawing)
    o.Value = o.RunMethod2("FromArgb",Color,"System.Int32")
    obj.Value = obj.GetProperty("TableStyles")
    obj.Value = obj.GetProperty2("Item",0)
    obj.SetProperty2("AlternatingBackColor", o.Value)
End Sub

Marvellous tip Erel. :sign0060:
Remembering some very old threads I think that a lot of "coders" will very pleased by this example.
