Comments

The ColumnsObj property returns the SftTreeColumns object.

The SftTreeColumns object describes attributes that apply to all columns in a SftTree/OCX control. Numerous properties and methods can be accessed using the returned object refColumnsObj. A control has only one SftTreeColumns object.

An individual column's SftTreeColumn object can be accessed through the control's Column property.

Examples

VB.NET

    Item.MaxHeightPix = 300 ' always exactly 300 pixels

    ' Form
    Dim f As FormSmall = New FormSmall()
    AxSftTree1.get_Item(6).Cell(1).AttachContentWindow(f.Handle, SftTreeContentWindowStyleConstants.contentWindowSftTreeKeepSize)
    AxSftTree1.get_Item(6).Cell(1).Text = ""

    AxSftTree1.RowHeaders.MakeOptimal() ' Make row header width optimal, so text and pictures are not clipped horizontally.
    AxSftTree1.ColumnsObj.MakeOptimal() ' Make all columns optimal

    ' triple the size of the last column
    AxSftTree1.get_Column(1).WidthPix = AxSftTree1.get_Column(1).WidthPix * 3

    AxSftTree1.Items.RecalcHorizontalExtent() ' Update horizontal scrollbar

    AxSftTree1.Items.Current = 0 ' select the first item

VB6

    Set Item = SftTree1.Item(5)
    Set Cell = Item.Cell(1)
    Cell.AttachContentWindow WebBrowserPictureBox.hWnd, contentWindowSftTreeNone
    Cell.Text = ""
    Item.MinHeightPix = 300 ' always exactly 300 pixels
    Item.MaxHeightPix = 300 ' always exactly 300 pixels

    SftTree1.RowHeaders.MakeOptimal ' Make row header width optimal, so text and pictures are not clipped horizontally.
    SftTree1.ColumnsObj.MakeOptimal ' Make all columns optimal

    ' Form
    Set SavedForm = New Form2
    SftTree1.Item(6).Cell(1).AttachContentWindow SavedForm.hWnd, contentWindowSftTreeKeepSize
    SftTree1.Item(6).Cell(1).Text = ""

    ' triple the size of the last column

C#

            // Form
            FormSmall f = new FormSmall();
            axSftTree1.get_Item(6).get_Cell(1).AttachContentWindow((long)f.Handle, SftTreeContentWindowStyleConstants.contentWindowSftTreeKeepSize);
            axSftTree1.get_Item(6).get_Cell(1).Text = "";

            axSftTree1.RowHeaders.MakeOptimal(); // Make row header width optimal, so text and pictures are not clipped horizontally.

            axSftTree1.get_Column(1).WidthPix = axSftTree1.get_Column(1).WidthPix * 3;

            axSftTree1.Items.RecalcHorizontalExtent(); // Update horizontal scrollbar

            axSftTree1.Items.Current = 0; // select the first item

C++

    // Create the dialog
    m_SimpleDialog.Create(IDD_SIMPLEDIALOG, &m_Tree);

    m_vTree->Item[6]->Cell[1]->Text = _T("");
    m_vTree->Item[6]->Cell[1]->AttachContentWindow((int) m_SimpleDialog.m_hWnd, contentWindowSftTreeKeepSize);

    m_vTree->RowHeaders->MakeOptimal(); // Make row header width optimal, so text and pictures are not clipped horizontally.
    m_vTree->ColumnsObj->MakeOptimal(); // Make all columns optimal

    // triple the size of the last column
    m_vTree->Column[1]->WidthPix = m_vTree->Column[1]->WidthPix * 3;

    m_vTree->Items->RecalcHorizontalExtent(); // Update horizontal scrollbar

    m_vTree->Items->Current = 0; // select the first item
    m_vTree->Item[0]->Selected = VARIANT_TRUE;
