setting position of color picker

**shannen** · July 25th, 2003, 10:23 AM

Hi all,
Does anybody know how I can get the PickColor control to start-up at a specified position? I tried setting the value in the following ways (psuedo code):
ColorPickerInfo.placeWhere=kAtSpecifiedOrigin;
ColorPickerInfo.dialogOrigin.v = 10;
ColorPickerInfo.dialogOrigin.h = 10;

Also, from the documentation, it mentioned that the dialogOrigin structure is suppose to contain the position of the dialog when it returns. Apparently, the debugging information that I got did not contain this. Appreciate for all help rendered and thank you very much once again

Does it work? If not, it might be saying that it starts at that distance from the default, which I believe is right next to the window you're selecting from. I'm not sure how to get it to behave correctly.

ai....sad to say, it does not work and tt't y i badly needed help on this. in fact, it does not even come out on the side of the window. it appears in the center of the screen, just like setting the placeWhere flag to the center. HELPPPPPP

I'm not familiar with Carbon, but I did find this: http://developer.apple.com/documenta...ger/index.html

Hi,
The following is the function that I wrote to prompt the ColorPicker dialog. The input parameter is the color that I wanted the dialog to pick. Everything works except for the position setting. Thank you all so much.
