 Posted: Sun Jan 07, 2007 4:38 pm Post subject: Where does the Mousedown go to |
 |
|
My problem problem seems to be that the onMouseDown event only seems to be triggered when clicking o the grid white space area, and not when clicking on any of the actual grid rows. The onMouseUp event is triggered OK on releasiing either button. I am trying to simulate the dragging and dropping of a grid row within the grid, so as you can appreciate it would be more elegant to capture the button mouse Down rather than button mouse Up. As an aside the onCellClick is only triggered by the mouse Up action, . I am currently using Delphi 7.
Thanks for any assistance |

line length or width.

Are you using a TDBGrid?

This is not the behavior of TStringGrid so it must be TDBGrid
and I do not use data-aware controls because none of the ones
that I have tried perform well enough for me. However, I'm
reasonably confident that you can subclass it's WindowProc
property and catch WM_LBUTTONDOWN which should be sent to the
control no matter where you click it.

Which is normal for any control that is clickable.

I cannot tell from your postings what newsreader/editor you two are
using. However, OutlookExpress v.6 uses a dynamic wrap to fit the
text to the window.just fine. I did not know that newsreaders with
problems doing this were still in common use. How common are they?

I have no clue about the old readers but questions do pop up
from time to time when I ask the OP to wrap their lines and
the general consensious is that it's actually an issue with
the server not dynamically wrapping the lines. If you use the
web interface to post, it even asks you to press return at the
end of each line.
For those of us that can't or don't use readers, it's a real
PITA when the lines are not wrapped and it's a simple thing
for the poster to set an option once and forget it.

JD,
Then I am showing my ignorance: I either never knew or forgot
that there was a Web interface (Besides Google Groups, which I
treat as ReadOnly). Where is your Web interface?

The longest line in your message was 63 characters. I will try
setting my wrap to that for this message and see what happens.
I suspect that it will probably insert extra new lines within
the quoted stuff. If it does, then that is my main complaint
against wrapping as it is commonly done.

Try http://newsgroups.borland.com
Not really very comfortable (it is an interface supplied by DNews, the
people who wrote the server software for the newsgroups), but with
direct access to the server, i.e. it is not a copy or archive, like
Google groups is. You access the real server data directly.

That was only because the edit window is about 65 characters
before it visually wraps (but no hard return is entered).

I just tested it with a width of 110 and there was room to
spare (about 5 more characters) so that would address your
concerns but the truth is that one should also be trimming
posts that are replied to so editing is needed anyway.
