AttachContentWindow Method, SftTreeCell Object
Attaches a content window to the cell.
Syntax
object
A SftTreeCell object.
Window
The window handle of the window to use for the cell as a content window. Specify NULL/Nothing to clear the cell's content window, so the cell's regular contents are shown instead.
Style
Defines options for the content window. Values of the following tables can be combined and used as Style value:
| Name | Value | Description |
|---|
| contentWindowSftTreeNone | 0 | None - No special handling. |
| contentWindowSftTreeKeepDisabled | 1 | Keep Disabled - The content window is always disabled. A content window is normally enabled and disabled as it is made visible or hidden. When contentWindowSftTreeKeepDisabled is specified, the content window is always disabled, even when it is visible. |
| contentWindowSftTreeKeepSize | 2 | Keep Size (Variable Height Tree Control) - The original size of the content window is preserved and the cell size adjusts accordingly. While a column can still be smaller or larger than the content window width, the content window is not resized, it is merely clipped. Without contentWindowSftTreeKeepSize, a content window is resized in height and width to fit within the cell. contentWindowSftTreeKeepSize has no effect in a fixed height tree control. |
Comments
The AttachContentWindow method attaches a content window to the cell.
If a content window is attached to a cell, the cell's regular contents (e.g., Cell.Text) are not shown.
The Cell.GetContentWindow method can be used to retrieve a cell's current content window settings.
