 Posted: Tue Feb 13, 2024 10:46 am Post subject: Replacing GET_MOUSE_POSITION with CLEARWIN_INFO |
 |
|
I'm upgrading a suite of programs from 32-bit to compile in 64-bit.
While in 32-bit, I have been upgrading a call to GET_MOUSE_POSITION (which has not been made available in clearwin64) to CLEARWIN_INFO.
For clarity, I've upgraded the calling routine to call either of the following two routines...
------
| Code: | SUBROUTINE GET_MOUSE_POSITION_OLD (IHOUT7, IVOUT7, IBS7)
C
USE mswin$
C
INTEGER(KIND=7) IHOUT7, IVOUT7, IBS7
INTEGER*2 IHOUT2, IVOUT2, IBS2
C
INTEGER(KIND=7) EBS7(1)
INTEGER*2 EBS2(4)
EQUIVALENCE (EBS7,EBS2)
C
CALL GET_MOUSE_POSITION$ (IHOUT2, IVOUT2, IBS2)
IHOUT7 = IHOUT2
IVOUT7 = IVOUT2
EBS7(1) = 0
EBS2(1) = IBS2
IBS7 = EBS7(1)
C
RETURN
C
C END OF SEGMENT GET_MOUSE_POSITION_OLD
C
END
C
C
C
SUBROUTINE GET_MOUSE_POSITION_NEW (IHOUT7, IVOUT7, IBS7)
C
USE mswin$
C
INTEGER(KIND=7) IHOUT7, IVOUT7, IBS7
C
IHOUT7 = CLEARWIN_INFO$ ('GRAPHICS_MOUSE_X')
IVOUT7 = CLEARWIN_INFO$ ('GRAPHICS_MOUSE_Y')
IBS7 = CLEARWIN_INFO$ ('GRAPHICS_MOUSE_FLAGS')
C
RETURN
C
C END OF SEGMENT GET_MOUSE_POSITION_NEW
C
END |
------
Using the first subroutine (_OLD), the software works fine, with the X,Y and FLAGS operating correctly.
With the second subroutine called (_NEW) it fails with the X,Y,FLAGS all being zero.
Interestingly, if I call the _NEW one immediately after the _OLD one, it returns the SAME values.
Is this because the CLEARWIN_INFO returns the information at the time of the last call back, whereas GET_MOUSE_POSITION is continuous (ie effectively initiates its own call back)?
This bears a large resemblance to the following post by GEWV, Posted: Tue Nov 26, 2013 9:59 am Post subject: get_mouse_position
That post doesn't offer a simple solution, like forcing the CLEARWIN_INFO to refresh which is what I would have hoped for, though PaulLaidler did suggest that get-mouse-position could be considered fo 64-bit. This routine is highly embedded in a whole suite of programs, and doesn't lend itself to a change in structure. |

get_mouse_position@ is exported by clearwin64.dll and can be accessed using
or
| Code: | C_EXTERNAL GET_MOUSE_POSITION@ "__get_mouse_position"(REF,REF,REF)

| For GRAPHICS_MOUSE_X etc. you will need the option [full_mouse_input] for the related graphics region. |
