Dialogs and Graphic Windows

[Kevin Cramer]

Is there anyway to put a graphic window onto a dialog? I have a need to show both an original video feed on a window with buttons and the associated callbacks, but also want to show the video with alterations on the same window separate from the source video. Right now I can do this with two separate windows, but this is very suboptimal.

So the question is whether it is possible to get the capabilities of a graphic window (e.g. - trapping mouse events and coordinates and then drawing lines on the video) on a dialog. It does not seem that dialogs can contain graphic windows or vice versa.

Any ideas?

Muchos Gracias...

A Graphic Window is intended to be a "standalone" window. On a Dialog, just use a Graphic Control (CONTROL ADD GRAPHIC). They are functionally identical.

Hi Bob,

When I try this:


DIALOG NEW PIXELS, 0, "Cramer Surveillance Inc", ,, 680, 400, _
%DS_MODALFRAME OR %WS_CAPTION OR %WS_SYSMENU OR %WS_EX_WINDOWEDGE OR %DS_SYSMODAL, 0 TO hdlg
DIALOG SET COLOR hDlg, -1, RGB(245,245,220)

CONTROL ADD GRAPHIC, hDlg,hWin,"",10, 5, imWidth, imHeight
GRAPHIC ATTACH hWin, hDlg, REDRAW


Then do some pixel setting like this:

FOR y = 1 TO imWidth
FOR x = 1 TO imHeight
rgbColor& = RGB(img2(y, imHeight+1-x).rgbtred,img2(y, imHeight+1-x).rgbtgreen,img2(y, imHeight+1-x).rgbtblue)
'rgbColor& = RGB(img(y, x).rgbtred,img(y, x).rgbtgreen,img(y, x).rgbtblue)

GRAPHIC SET PIXEL (y, x) , rgbColor&

NEXT y
NEXT x

GRAPHIC REDRAW

The graphic window is there where I want it, but is blank. It seems that the redraw does not happen...

I see that I had the handles reversed...now it works...
