Re: Databrowser redrawing

What I'm doing is this. In the DB, 1 column is a custom column, in which I draw something which resembles a scroll bar, which you can also resize by dragging it's edges.
On top of that, I need to draw over the whole column (also on the columns title) a line defining a reference point in the range of the scrollbars. This line is not specific to one cell but to the whole column.

1) For some reason the clip rect the DB sets before calling my custom
item draw, is offseted to the left of the DB, regardless of where the
column actually starts (the bounds rect passed as a parameter to the
function is OK though). This is kind'a strange since I can draw outside
the clip area (I draw to my cell's boundries).
Another problem with this, is drawing selected items, their clip area is
set such that you can draw on the scroll bars.
Has anyone seen this.

This seems like a bug.

I'll file one.

2) The min/max column width refer to the actual column width (as seen on
the titles), although the actual area allocated for the column's cells
is a bit less on both sides. Is there a way to know what this size is,
or how to set it?

I am not sure if that what you are asking for, but there is
"titleOffset" field in "DataBrowserListViewHeaderDesc" structure
used when column is created. "min" and "max" column widths are
the fields of the same structure.


What I mean is this. When my custom draw function is called the bounds given to it are smaller (in width) from the bounds I get from GetDataBroserIterPartBounds() when requesting the kDataBrowserPropertyEnclosingPart.

The bounds GetDataBroserIterPartBounds() return are consistent with where the column separators on the title line of the DB appear. The bounds sent to the draw function, are inset from them. In my case it's inset to where the title text is put (maybe just by chance).

So the problem is this. If I set a DB custom column minimum width to 30 for example. The actual minimal size my cell has to draw itself in (when the custom draw is called) is less then that.
