SetFocus, KillFocus, BeginDragDrop, MoveDragDrop, EndDragDrop, RightButtonClick, RightButtonDoubleClick, Expand, Collapse, LeftButtonDownClick, RightButtonDownClick, LeftButtonDoubleClick and MouseMove of the TREE_COLUMN object.

Note: This property is not available in Java generation.

Number of the column that triggers the events:

DD_BeginDrag, DD_EnterDrag, DD_DragOver, DD_Drop and MouseMove of the TREE_LIST object;

SetFocus, KillFocus, BeginDragDrop, MoveDragDrop, EndDragDrop, RightButtonClick, RightButtonDoubleClick, Expand, Collapse, LeftButtonDownClick, RightButtonDownClick, LeftButtonDoubleClick and MouseMove of the TREE_COLUMN object.

The TREE_COLUMN objects of the tree list are numbered from left to right starting with 1.

Note: This property is not available in Java generation.

Defines the adjustment of an object placed in the view of a split bar object, when the user drags the horizontal bar below the object, or when he/she resizes the window below and when the split bar expands (VERTICAL_ADJUSTMENT property equal to _SPLT_ADJUST_EXPAND_HEIGHT) and if the object belongs to one of the bottommost views.

Note: This property is not implemented in Java and Mobile generation.

Defines the adjustment of an object placed in the view of a split bar object, when the user drags the vertical bar to the left of the object, or when he/she resizes the window below and when the split bar expands (HORIZONTAL_ADJUSTMENT property equal to _SPLT_ADJUST_EXPAND_WIDTH) and if the object belongs to one of the rightmost views.

Note: This property is not implemented in Java and Mobile generation.

Defines the adjustment of an object placed in the view of a split bar object, when the user drags the vertical bar to the right of the object, or when he/she resizes the window below and when the split bar expands (HORIZONTAL_ADJUSTMENT property equal to _SPLT_ADJUST_EXPAND_WIDTH) and if the object belongs to one of the rightmost views.

Note: This property is not implemented in Java and Mobile generation.

Defines the adjustment of an object placed in the view of a split bar object, when the user drags the horizontal bar above the object, or when he/she resizes the window above and when the split bar expands (VERTICAL_ADJUSTMENT property equal to _SPLT_ADJUST_EXPAND_HEIGHT) and if the object belongs to one of the bottommost views.

Note: This property is not implemented in Java and Mobile generation.

Allows the object to be placed in focus. Objects placed in focus will respond to the user's keyboard and mouse actions.

RGB color used to draw the background for the object.

Note: This property is not implemented in Mobile generation.

Specifies whether the object can be the destination of drag and drop operations (new version only).

Note: This property is not implemented by the Java generator.

Specifies the display of a double border.

Specifies the display of a border with embedded outlines.

Number of the first visible line in the object. Line numbers begin with 1.

Character font used to display the text in all elements in the object.

The string format contains the name, size, style and script, in that order. A semi-colon must be inserted between each element.

If you set a property's value, you MUST specify the name and size.

The different styles are specified using the following values:

• • 1: Normal (no special style)
  • 2: Strikethrough
  • 16: Italics
  • 256: Bold
  • 4096: Underlined

The style value to be specified in the string can either be one of the above values or else the sum of values other than 1.

The different script values are as follows:

Note: The size, style and script must be compatible with the chosen font. The Windows system font selection dialog box, accessible via the graphical object's Properties pages, provides a guide for selecting coherent values.

Specifies how the selected TREE_COLUMN element is to be shown. If this property is set to *TRUE, the element's whole line will be selected. If this property is set to *FALSE, only the text in the element's line will be selected.

Note: This property is not implemented in Mobile generation.

Specifies the first object in an object group. An object group is defined by its first object, and includes all the objects following it (according to the object sequence) until the first object in another group is reached. The user can use the arrow keys to change focus from one object to another within the same group.

Specifies the use of expand / collapse buttons for node handling. If this property is set to *TRUE, an expand / collapse button will appear to the left of each node. You can expand or collapse the associated node by clicking on this button.

Specifies the display of a link between a node and its sub-branches.

Object's height value.

Defines how the graphical control is adjusted when the window is resized horizontally.

Note: This property is not implemented in Java and Mobile generation.

Specifies the display of a link between all the children leading from the root node.

List of the elements in the object.

Static name of the object.

Authorizes the object to draw itself over a control positioned in front of it in the window object order.

In the particular case where the window has a background image with transparent images placed in foreground, it is necessary to set the property to *TRUE if you wish to put the object after a "transparent" object in the tab order.

Reminder: an "overlapped" object must be placed after the background image, while a "non-overlapped" object must be placed before the background image.

For more information about managing overlapping of graphical objects, consult the working with object overlap section.

Note: This property is not implemented by the Java and Mobile generators.

Enables the Rolldown event to be triggered.

Enables the Rollup event to be triggered.

Specifies the use of horizontal and vertical scroll bars inside the object (only visible if required).

Note: This property is not implemented in Mobile generation.

Used to manage how the selected TREE_COLUMN element is displayed when the object loses the focus. If this property is set to *TRUE, the element will remain selected onscreen. If this property is set to *FALSE, the selected object will be deselected.

Specifies how node expansion / collapsing is managed. If this property is set to *TRUE, the selected node will automatically be expanded, and the deselected node will be collapsed.

Specifies the display of a border with static outlines (3D effect used to show objects not immediately placed in focus).

Allows the object to be placed in focus using the keyboard (Tab key or Shift+Tab).

Enables the TREE_COLUMN element under the mouse cursor to be highlighted. The text for this element will be displayed underlined and in blue.

Defines how the graphical control is adjusted when the window is resized vertically.

Note: This property is not implemented in Java and Mobile generation.

Visibility of the object. Only visible objects can be placed in focus.

Object's width value.

X coordinate value of the object's position relative to the area covered by the window, page or pane. The reference point (origin) is the top left-hand corner of the object.

Y coordinate value of the object's position relative to the area covered by the window, page or pane. The reference point (origin) is the top left-hand corner of the object.
