Can I split a spinbox control?

[Egbert Zijlema]

Is it possible to split a spinbox control ("msctls_updown32") in 2 separate arrow buttons (left and right, using %UDS_HORZ-style)? I want a "home"-button in between. As normal the left arrow will count down, the right one up and the button in the middle should restore the initial setting of the counter.

How about three side-by-side tiny button controls? To get the arrow keys you'll have to subclass but AFAIK updown controls are bipolar only,

(Us sytle BS_BITMAP, and the arrow BMPs are standard ones you can load with LoadBitmap or LoadImage).

It's fairly simple to use regions.
You simply remove the unwanted part.
Of course you need to calculate all kind of things.

Here it is:

    Local hWndCtrl As Long
    Local hRgn As Long
    Local R As RECT

    Select Case nCbMsg
    Case %WM_INITDIALOG
    
        hWndCtrl = GetDlgItem( CbHndl, %ID_FORM1_UPDOWN1 )
    
        GetWindowRect( hWndCtrl, R )    
        hRgn = CreateRectRgn( 0, 0, R.nRight - R.nLeft, ( R.nBottom - R.nTop ) / 2 )
        SetWindowRgn( hWndCtrl, hRgn, 1 )

Unfort. standard arrow bmps are scrollbar arrows

Thanks guys,

Michael: I've tried the standard bitmaps (%OBM_LFARROW et cetera), but it is not possible to enlarge them. So what you get is the scrollbar size arrow, which is too small in comparision to its neighbouring buttons.

Edwin: I'll try your suggestion tomorrow. The spinbox arrows can be resized, therefore I prefer a "split solution" with those bitmaps.

???
CONTROL ADD IMGBUTTONX didn't stretch the arrow image?

[Egbert Zijlema]

Hello Dale,

The so called standard bitmaps in Windows need to be loaded using LoadBitmap or LoadImage (API functions) and then should be sent (SendMessage) to a bitmap style button control (%BS_BITMAP). One cannot use CONTROL ADD IMGBUTTON(X).

Edwin's idea does not work

Well, it's a couple of days later than "tomorrow", but today I've tried Edwin's suggestion. It does not work quite well. I only can use one half of the same control. Maybe I should use the halfs of 2 different spinners? I'll give it a try, but perhaps it is a lot simpler to create my own IMAGEX arrow buttons, using an image editor.
