SPACE_AreaBox broken?

[tbreeden]

I'm unable to get reasonable results when doing a GetAttrs() for SPACE_AreaBox. (4.1 upd 6, SDK 53.20).

The function returns 1, and the IBox variable is written into, but the values don't make any sense.
Doing a GetAttrs() for GA_LEFT/TOP/WIDTH/HEIGHT does work.

The main thing is that the GA_xxxx values include the bevel part when SPACE_BevelStyle is not none.
From the Autodocs, I got the idea that SPACE_AreaBox should be only the inner area, not including the
bevel pixels.

eg, for GA_LEFT returned as 7, GA_TOP 33, GA_WIDTH 696, GA_HEIGHT 468
the corresponding SPACE_AreaBox values might be box.Left of 23989, box.Top of -26296, box.Width of 0, box.Height of 0

The box.Left and box.Top seem to be pretty random (with the same size Space they may be quite different next time, but the box.Width and box.Height always 0. I explicitly initialized the IBox to 0's before the GetAttrs().

Anyone seen this?

Thanks,

Tom

How are you getting that attribute? Can you post the source line that queries for it?

GetAttr(SPACE_AreaBox) fills in a pointer to an IBox, it does not fill in an IBox you supply.

This works right:

Code: Select all

struct IBox *box;
GetAttr (SPACE_AreaBox,spaceobject,&box);
Printf ("x=%ld; y=%ld; w=%ld; h=%ld\n",box->Left,box->Top,box->Width,box->Height);

Also remember that the contents of the IBox are 16-bit words, not 32-bit longs. If you use an expression like DebugPrintF ("%ld\n", IBox->xxx), you will read junk. You have to either copy the 16-bit values to 32-bit variables before printing, or cast the printed args.

If you use an expression like DebugPrintF ("%ld\n", IBox->xxx), you will read junk.

That's not true. The compiler will convert the values to 32bit. It's rather so that you have to use %ld even for 16bit values and you will get junk if you use %d.

Indeed, that was the problem. I was expecting it to fill in the IBox in my program for which I put the address into the TagData.
