PureBasic Forums - English

Hello everybody. I got tired to the usual windows WC_LISTVIEW Class. All the work-arounds to subclass and draw my own controls in it
or custom-drawing it.. So I wrote this "xListView" class from scratch. It took me almost a week to get it to where I could use it in some apps for work.
My boss was fussing, by I needed it because it was SO versatile. Any ways, I'm always finding little bugs and stuff, and the Library is too big to just pop the code in, but if there is anyone out there who would like to help finish the ultimate ListView, please help out! There are a lot of Messages that I didn't have the
WndProc() handle, that are listed. There's a small example program there to show the basics of how to use it. Anyways, if anyone takes a look that would be great because there's nothing better than a spicy-hot list-view control!

Would very much like to see this, but the link is dead .

Oops, yes. Microsoft just updated my dang web server and IIS is down now, have to see what happened. I'm at work now, but I'll check into it this PM an re-post the link.

Here you go!
Got it up and running, sorry was busy at work. I included a small sample program at the bottom of the customlv.pb file.
Just look through the messages defined at the top of the file

LVM_GETTEXT, I have defined messages to change color of cells selected, non-selectable, and not selected. I also have a cool search built in, so
that it you have column 2 with focus, as you type into column 2 (assuming you haven't embedded a control) it will search all column 2's for whatever text your're searching for and find that row, kind of like the WC_LISTVIEW class does for column 0 on theirs, however on this one, it doesn't search from left to right. It searches
using FindString() for any match in the columns for what's in the search buffer. I think i set the search buffer to clear after 1 sec. But check it out.

Notes:

myRetVal.s = PeekS(SendMessage_(hListView, #LVM_GETTEXT, iRow, iCol)) ;<- Gets the text in a cell

SendMessage_(hListView, #LVM_SETTEXT, MakeRowCol(iRow, iCol), *lpszText) ;<- Sets the text in a cell.

Um...
Oh and you have some cool events.
LVN_CBSELCHANGE
LVN_DOWN = If the user hits enter anytime the hListView has focus (embedded control or not) (HIWORD) wParam = Row (LOWORD) wParam = Col...lParam = hListView...This is good for creating a new Row if they are at the bottom

LVN_CBNKILLFOCUS
LVN_EDITCHANGE

The control DOES send WM_NOTIFY messages and standard NM_CLICK, NM_RCLICK, but I have it send the bulk of the LVN_ messages DIRECTLY to the parent window's WndProc(). I don't know, we could switch them to WM_COMMANDs, but I didn't bother.

just email me if you have any questions on it: justin@justinjack.com

Not bad.
Two things I noticed:
There's a scrollbar in the dropdownbox in the first column, which is not needed when there are only a few items.
When I add 10 more items to the LL the scrollbar is needed, ofcourse, but scrolling with the mouse-wheel doesn't work (the ListView is scrolled instead).

And when I click the checkboxes, sometimes the last cell I clicked into is highlighted, too.

Yup, I use it myself mostly for the functionality of the combobox and edit field to create invoice-like-forms. I needed a grid that you could type in and the cell would grow and wrap to fit the text in, I haven't actually used the checkbox for anything yet, I kind of fix bugs as they come up. That's the latest version i've been using. But ideally I'd like to be able to set a background image on it, kind of like a water-mark or logo, or just add more graphic functionality.

Yeah there's a bug with the combobox, I need to set the dropped width a little better or something.

JustinJack (and just because I am so supremely evil), INTEROCITER is spelt Interossiter:):)

That's it, I am falling on the floor howling.

I actually saw the black and white SciFi film 35 years ago when they first mentioned Interossiter and I loved it. Couldn't take it seriously (Should have seen the hairdos!!!!)

Back on topic: Nice looking control, could come in very useful.
