  • 项目

BOOLIsButtonIndeterminate(intnID**) const;**

Return Value

Nonzero if the button is indeterminate; otherwise zero.

Parameters

nID

Command identifier of the button in the toolbar.

Remarks

Call this function to determine whether the specified button in a toolbar control is indeterminate. Indeterminate buttons are displayed grayed, such as the way the bold button on the toolbar of a word processor would look when the text selected contains both bold and regular characters.

Consider calling GetState if you want to retrieve more than one button state.
