AllowKeysEnum Constants (ExGraph)

The AllowKeysEnum type specifies the keys to be combined in order to start an UI operation. For instance, the AllowScroll property of the AllowKeysEnum type specifies the key combination that allows the user to scroll the chart at runtime. By default, this property is set to exLeftClick, which means the user can scroll the chart with a single left click. If this property is set to exRightClick + exCTRLKey, the user must hold the CTRL key while right-clicking to start scrolling. If the exDblClick flag is included, the user must double-click instead of single-click to perform the operation. The exDisallow flag indicates that scrolling is not permitted.

The AllowKeysEnum type supports the following values:

Name	Value	Description
exDisallow	0	The operation is not allowed.
exLeftClick	1	The operation starts once the user clicks the left mouse button.
exRightClick	2	The operation starts if the user clicks the right mouse button.
exMiddleClick	3	The operation starts if the user clicks the middle mouse button.
exSHIFTKey	8	The operation may start only if the user presses the SHIFT key.
exCTRLKey	16	The operation may start only if the user presses the CTRL key.
exALTKey	32	The operation may start only if the user presses the ALT key.
exDblClick	64	The operation starts only if the user double clicks, instead single click.
