SETMOUSECURSOR

Graphics Function: Sets the shape of the mouse cursor for the window in focus.

Module:

USE DFLIB
USE DFWIN

Syntax

oldcursor = SETMOUSECURSOR (newcursor)

newcursor
(Input) INTEGER(4). A Windows HCURSOR value. For many predefined shapes, LoadCursor(0, shape) is a convenient way to get a legitimate value. See the list of predefined shapes below.

A value of zero causes the cursor not to be displayed.

Results:

The result is of type INTEGER(4). This is also an HCURSOR Value. The result is the previous cursor value.

The window in focus at the time SETMOUSECURSOR is called has its cursor changed to the specified value. Once changed, the cursor retains its shape until another call to SETMOUSECURSOR.

In Standard Graphics applications, units 5 and 6 (the default screen input and output units) are always considered to be in focus.

The following predefined values for cursor shapes are available:

Predefined Value	Cursor Shape
IDC_APPSTARTING	Standard arrow and small hourglass
IDC_ARROW	Standard arrow
IDC_CROSS	Crosshair
IDC_IBEAM	Text I-beam
IDC_ICON	Obsolete value
IDC_NO	Slashed circle
IDC_SIZE	Obsolete value; use IDC_SIZEALL
IDC_SIZEALL	Four-pointed arrow
IDC_SIZENESW	Double-pointed arrow pointing northeast and southwest
IDC_SIZENS	Double-pointed arrow pointing north and south
IDC_SIZENWSE	Double-pointed arrow pointing northwest and southeast
IDC_SIZEWE	Double-pointed arrow pointing west and east
IDC_UPARROW	Vertical arrow
IDC_WAIT	Hour glass

A LoadCursor must be done on these values before they can be used by SETMOUSECURSOR.
