For word Processing we need a mouse that can handle double and triple clicks, along with drag, right click, the mouse wheel, and we'll throw in middle clicks because I'm fresh out of kitchen sinks...
Code: (Select All)
Type mousevar
mx As Integer ' Row.
my As Integer ' Column.
wh As Integer ' Wheel.
lb_status As Integer ' Left Button Status.
rb_status As Integer ' Right Button Status.
mb_status As Integer ' Middle Button Status.
click As Integer ' Number of timed left button clicks.
CursorStyle As Integer ' 0 Default, 1 Link style. (Hand).
mousekey As String ' Auto Keyboard Input.
End Type
Dim m As mousevar
i = 3: j = 1: a$ = "None" ' Seed.
Do
_Limit 60
' Demo portion...
If j > 80 Then i = i + 1: j = 1: If i > 24 Then End
Select Case m.click
Case 1: a$ = "Single": If m.lb_status = 2 Then a$ = "Drag"
Case 2: a$ = "Double"
Case 3: a$ = "Triple"
End Select
Select Case m.wh

End Select
Locate 1, 3: Print "Row:"; m.my;: Locate 1, 11: Print "Col:"; m.mx;
Locate 1, 23: Print "Lt:"; m.lb_status; " Rt:"; m.rb_status; " Md:"; m.mb_status; " Whl: "; b$; " Last Left Click: "; a$; " ";

Thanks! The routine does take into account vertical as well as horizontal drag movement, but maybe I'm not understanding your question correctly. Let's apply the mouse routine to a cheap-ASCII chess example. I made CHR$(219) a queen and lets drag her all around SCREEN 0!

I know, I miss the days when CHR$(219) was a king, but now it's a drag queen, oh well.
(04-28-2024, 07:39 PM)James D Jarvis Wrote: Cool. What would code for scrolling a selected queen look like ? (Asking for a lazy friend).
For an ASCII chess board, with simple letters representing the pieces, the "Q" for queen would be moved with the same code used to move the CHR$(19) block in the previous example. Now for graphics, it's more complicated. A range is needed to detect the chess piece and there is masking involved to go along with the movement. You might want to look up the graphic Chess Board by TheBOB in the Prolific Programmers section. I believe he has a mouse routine to move the pieces.
