When customdrawing on a control, is it possible that someone can
explain a few things to me please.
Since I am trying to do different things with a listview, I will
ask questions pertaining to a listview.
Lets say that I want to draw some items on a Listview grid, with
the code that Gambit posted for me with the progressbar, it
looks really simple and makes you want to experiment more. But
I want to ask these just in case I am not understanding
something.
When you use the following code to get the rectangle of the
listitem: TRect ItemRect = Item->DisplayRect(drBounds);
If I want to place an icon before the text, do I just leave a
certain amount of spaces for the icon then write the text? I
ask this because I have seen some code that uses a lot of
calculations to know where to put the text for the entire row.
When looking at code like that I never understand it at all, but
looking at the code that I have makes it seem so simple to understand.
From what I read in the help file, this code just gets the
rectangle of the current item: TRect ItemRect = Item->DisplayRect(drBounds);
I guess I am not asking what I am trying to ask very clearly,
maybe I better experiment first, then ask the question when I
get stuck.

text yourself, since you are putting it in a non-standard position.
Otherwise, just use the icon support that the ListView already has. List
items can already display icons in front of their text without owner-drawing
them.
The drawing events are triggered on a per-item basis. The code is
calculating and drawing the Item that the event specifies needs drawing.

difficult when selecting the entire row. That is what I had a
problem with the first time before you helped me out. The
selected row would not highlight the area that I had to write
in.
before but I could never it to work. I don't remember exactly,
but I think when you don't use an icon, there is a blank space
before the text, and it looks different.
Is there any way to set the checkbox to another column besides
the first?
I am really trying to make this as easy as possible, this way
I would understand a lot more of exactly how to do this on my
own.
Thanks again
