Property Value

Type	Default	Description
DefaultBoolean	**Default**	A DefaultBoolean enumeration value that specifies whether it is allowed to scroll pictures using the mouse wheel.

Available values:

Name	Description
True	Corresponds to a Boolean value of true.
False	Corresponds to a Boolean value of false.
Default	The value is determined by the current object’s parent object setting (e.g., a control setting).

Remarks

Scrolling using the mouse wheel can be performed in the following cases:

• the AllowScrollOnMouseWheel property is set to Default and the RepositoryItemPictureEdit.ShowScrollBars is set to true;
• the AllowScrollOnMouseWheel property is set to True.

The mouse wheel can also be used to zoom pictures (see RepositoryItemPictureEdit.AllowZoomOnMouseWheel). By default, zooming is performed if the CTRL modifier key is pressed (see RepositoryItemPictureEdit.ZoomingOperationMode), scrolling is performed if no modifier key is pressed. If no modifier key is required to zoom pictures, scrolling using the mouse wheel cannot be performed.
