Tree_EnsureVisible Method

This method ensures that the indicated tree item is visible.

MyControlReference: Reference to the control in the form of MyProject_MyForm_MyControl.
ProjectFile: String identifying the project as it was passed in LoadProject.
DialogName: String identifying the dialog by name.
ControlName: String identifying the control by name.
Key: String specifying the a unique key in the tree structure identifying the tree node.; Tree Node Handle specifying the tree node uniquely.

Returns the following according to the situation:

T when successful.
Nil if the dialog is not found, the dialog does not support this function or the node is not found.

The recommended convention is passing the control identifier directly:

Copy Code
(Odcl_Tree_EnsureVisible MyControlReference [as Reference] Key [as String or Tree Node Handle])

An alternative convention is to identify the control by providing the project file, the dialog name and the control name:

Copy Code
(Odcl_Tree_EnsureVisible ProjectFile [as String] DialogName [as String] ControlName [as String] Key [as String or Tree Node Handle])

Copy Code
; Ensure a tree item is visible in the control (Odcl_Tree_EnsureVisible MyProject_MyForm_MyControl "C_Documents and Settings")
