1. RE: EuGrid: Grid Control for Win32lib
Dog-gone it, Phil.
I already submitted one (a very early release) about 3 weeks ago and
here you've been working on one too! :)
I'm very interested in seeing what you did and how you approached
creating the grid. I'm a few days away from another submission of my
grid control as well.

2. RE: EuGrid: Grid Control for Win32lib
Phil (and everyone else)...
Just tried your EuGrid and I must say I was quite impressed!
To that end, I hereby announce that I will STOP working on my grid
control. If you were using mine or plan on using mine then take a look
at Phil's control.
I noticed that you have on future enhancements check boxes, combo box,
button, picture, etc. Could I suggest a date control that brings up a
date selector? Also a control that allows selection of a file that
brings up an "Open File" dialog box.
Good work!

Hi Jonas,
Thanks very much for your comments. I would be particularly interested
in any feedback you have as you belong to the (very small) club of
people who know both the joy and pain of grid control construction

Can't see why not. If memory serves this was implemented in the first
version of your grid control - do you mind if I nab the code?
BTW I am currently trying to figure out how to implement a combo box
cell type. Using a native combo box is a problem as it seems to be
difficult/impossible to size them correctly. Did you get any further
with the combo box cell type in the latest version of your grid control?
Regards,
Phil
4. RE: EuGrid: Grid Control for Win32lib
Phil,
Please, help yourself to whatever suits your needs in my grid. I liked
that your grid was closer to the API as changes in win32lib would
probably not break the grid. Hopefully mine will translate as I used
win32lib calls for the windows stuff.
I wound up simulating a drop down by creating an edit control and then
placing a button with a '?' as the caption to the right of the edit.
Then when the button was pressed I would show a list box right below the
edit control. Probably not the best way but all I could figure out
using win32lib.
I did notice a couple of things (minor) with your grid. Using the
simple.exw example, tab over to an email address and press Enter in the
edit control. The text disappears and when you move off the control a |
is displayed in the first position of the cell. Move back to the cell
and the text disappears. I assume this is because of the enter key
inserting a new line into the control.
Also, when you tab to the right to a cell that is partially displayed it
would be nice if the grid automatically adjusts to display the entire
cell.
Again, just minor things. I can't tell you how relieved I was today
when I realized I didn't have to keep banging my head to get mine to
work!.

Yeah - I am starting to suspect that might be what I have to do. I have
started looking at owner-draw combo boxes but then you have to code
*absolutely everything* including painting the contents of the list box
etc. Sigh...

You're quite right. The reason is that the edit window that I use is
defined as a multi-line edit field because a single line edit field
displays a different caret on win95 depending on the text alignment of
the field. For some reason defining a multi-line edit field makes this
problem go away. It occurred to me a while ago to include a column
property of single/multi-line edit for editable fields and disallow
enter key input for single line edits. This would allow users to enter
several lines of text so long as they made the row height large enough.
I forgot all about it until you reminded me...

Good point - the cell visibility processing doesn't handle this at the
moment.

I know what you mean. I think if I had realised how much work it was
going to take to get it working even half-way right I probably wouldn't
have bothered. I actually had a fairly functional version about 6 months
ago but the code was just too poorly structured and inflexible to allow
for changes. I went back and rewrote it from scratch - which took
forever but at least now it is fairly easy to modify. I can't tell you
how relieved I was to finally release the d**n thing.
Thanks again for the feedback,
Phil
