SetControl32BitMinimum

SetControl32BitMinimum
Header:	Controls.h		Carbon status:	Supported

Changes the minimum setting of a control and, if appropriate, redraws it accordingly.

void SetControl32BitMinimum (
    ControlRef theControl, 
    SInt32 newMinimum
);

theControl: A handle to the control whose minimum setting you wish to change.
newMinimum: A value specifying the new minimum setting of the control. In general, to avoid unpredictable behavior, do not set the minimum control value higher than the current maximum value.

DISCUSSION

Your application may use the SetControl32BitMinimum function to set a 32-bit value as the minimum setting for a control.

If your application uses a 32-bit control minimum value, it should not attempt to obtain this value by calling the pre–Mac OS 8.5 function GetControlMinimum or by accessing the contrlMin field of the ControlRecord structure, because the stored 16-bit value will not accurately reflect the current 32-bit control value. Instead, use the function GetControl32BitMinimum.

VERSION NOTES

This function is available with Mac OS 8.5 and later.

AVAILABILITY

Supported in Carbon. Available in Mac OS 8.5 and later when Carbon 1.0.2 or later is present.
