Let's Make a Wheel!
#1
Well, we already have one called a mouse wheel. I know how much bplus loves them so I thought I'd put a mouse highlighting "wheel" function into a menu routine I am morphing into a library.

Now this works as a roughed out 'Demo' but I'd appreciate some critique before I keep working on it.

Code: (Select All)
_ScreenMove _Middle
_Font 16
Dim Shared MenuBdrFg, MenubrdBg, MenuSdwFg, MenuSdwBg, MenuFg, MenuBg, MenuHlFg, MenuHlBg
Restore color_palette_data
For i = 1 To 15
    Read j, k
    If k <> -1 Then Palette j, k
Next
For i = 1 To 8
    Read j
    Select Case i
        Case 1: MenuBdrFg = j
        Case 2: MenubrdBg = j
        Case 3: MenuSdwFg = j
        Case 4: MenuSdwBg = j
        Case 5: MenuFg = j
        Case 6: MenuBg = j
        Case 7: MenuHlFg = j
        Case 8: MenuHlBg = j
    End Select
Next
CurStyle = 1
MenuWidth = 0
bgc1 = 9: bgc2 = 1 ' Background appearance.
While -1
    Color MenuHlFg, MenuHlBg
    Cls
    Color 14, 1
    Locate 2, 1: Print String$(80, 196);
    Locate _Height - 1, 1: Print String$(80, 196);
    Color bgc1, bgc2
    For i = 3 To _Height - 2
        Locate i, 1: Print String$(80, 176);
    Next
    Color 14, 1
    Locate 1
    text$ = "Menu Options"
    Print center$(text$);
    Locate _Height
    text$ = "[F1] Help  [Esc] Quit"
    Print center$(text$);
    Restore menu_data: dcnt = 0: mhl = 0
    Do
        Read dta$
        If dta$ = "eof" Then Exit Do
        If _Height \ 2 <= (dcnt * (spacing + 1) + 1) \ 2 + pop Then Exit Do ' Data exceeds window max menu height.
        dcnt = dcnt + 1
        ReDim _Preserve a$(dcnt)
        If Len(dta$) > MenuWidth - 4 Then
            MenuWidth = Len(dta$) + 4
            MenuLeft = _Width \ 2 - Len(dta$) \ 2 - 2 + 1
        End If
    Loop
    Restore menu_data

Am I missing anything? The wheel choices can be activated with Enter, left or middle mouse click. There is no need to put the pointer in the menu to use the mouse. I thought about having the wheel initiate highlighting from the bottom up if the first roll if negative, upwards, but maybe that's too corny.... Steve would know.

Also line 103 to 147.... these....

Code: (Select All)
If Len(b$) Then
action$ = "key"
ElseIf mw Then
action$ = "wheel"
ElseIf oldmy And my <> oldmy Or oldmy And mx <> oldmx Then
If my > MenuTop - pop And my < MenuTop - pop + MenuHeight - 1 And mx > MenuLeft - pop + 1 And mx < MenuLeft - pop + MenuWidth - 2 Then
action$ = "mouse-in"
Else
If action$ <> "wheel" And action$ <> "key" Then
action$ = "mouse-out"
End If
End If
End If
j = 0
Select Case action$
Case "wheel", "key"
If mhl + mw > 0 And mhl + mw <= UBound(a$) Then
j = mhl + mw
End If
Case "mouse-in"
j = (my - MenuTop + pop + spacing) / (spacing + 1)
Case "mouse-out"
If CurStyle And mshow$ <> "DEFAULT" Then mshow$ = "DEFAULT": _MouseShow mshow$
If mhl Then
s1 = CsrLin: s2 = Pos(0): c1 = _DefaultColor: c2 = _BackgroundColor
Locate MenuTop - pop + mhl + (mhl - 1) * spacing, MenuLeft - pop + 2 - 1: Color MenuFg, MenuBg: Print " " + a$(mhl) + " "; ' Unhighlight.
mhl = 0
End If
End Select
If j And Int(j) = j Then
If j <> mhl Then
s1 = CsrLin: s2 = Pos(0): c1 = _DefaultColor: c2 = _BackgroundColor
If mhl Then Locate MenuTop - pop + mhl + (mhl - 1) * spacing, MenuLeft - pop + 2 - 1: Color MenuFg, MenuBg: Print " " + a$(mhl) + " "; ' Unhighlight former.
Locate MenuTop - pop + j + (j - 1) * spacing, MenuLeft - pop + 2 - 1: Color MenuHlFg, MenuHlBg: Print " " + a$(j) + " ";: Locate s1, s2: Color c1, c2: mhl = j ' Highlight current.
End If
Select Case action$
Case "mouse-in"
If lb = 2 Then b$ = LTrim$(Str$(j))
If CurStyle And mshow$ <> "LINK" Then mshow$ = "LINK": _MouseShow "LINK"
Case "wheel", "key"
If mb = 2 Or lb = 2 Then b$ = LTrim$(Str$(j))
If CurStyle And mshow$ <> "DEFAULT" Then mshow$ = "DEFAULT": _MouseShow mshow$
End Select
End If

... determine the behavior of using arrow up/down keys, wheel, and mouse pointer with the routine. If anyone sees some optimization that can be applied to these 44 lines, I'm all ears. No Steve, not corn ears. Now that would be corny.

Merry Christmas Eve eve @Pete

Testing your code, I had error pop up when going from triple space to double to single error!
   

Not critical as if I continue and continue again for 2nd error popup, it seems everything is back as it should be.

I am impressed how wheel handles the different spacing. still playing with it...

Question: Have you been changing anything in MyMouse routine?
b = b + ...

@bplus

Fixed. I had to add in an action$ = ""  when it re-loops; otherwise the variable a$(j) was one higher than the upper-bounds due to the popup changing coordinates.

It's the same MyMouse routine.

Thanks!

Things are going quite well for me.
Only in the help (F1) should you reset the 'help$' variable, otherwise the popup gets longer and longer the more often you call up the help.

Ah, great point! +2.

I made that edit to the first post.
