I think it's easy to solve with egrid_CreateCellCallback().

It's better if it is possible to control it. Perhaps it would be a good idea to use a flag like '#egrid_AlwaysShowSelection'

Good idea, I'll get on it.

SUCCESS!!!

Have managed to 'persuade' Tailbite to produce a unicode version of egrid - which doesn't crash!!!

A bit more testing to do, but fingers crossed...

**EDIT: have been busy today! Shift/tab works as requested. Have added an extra flag #egrid_AlwaysShowSelection used when creating an egrid which works as requested by Thorsten1867 (above) and of course have managed to create a unicode version of the library.
I won't be able to upload until later though as I am away from my broadband connection at the moment.

@mskuma: I don't necessarily see a problem with using an egrid for large datasets. After all, an egrid is simply a ListIcon given an extra polish and a fresh coat of paint! If it does slow down too much, then consider using a standard header as opposed to a custom one. Also, go easy on other customisations perhaps.
I do intend allowing for 'virtual' egrids at a later date which should also help when using very large data sets etc.

**UPDATE: 8 October 2006.

A few ammendments (still at beta 2).

Have added 'shift/tab' functionality to tab in reverse through the grid etc. Have ammended the egrid_AddColumn() function so that a column index of -1 causes the new column to be appended etc. Have also added the creation flag #egrid_AlwaysShowSelection which prevents the selection box from vanishing whenever an egrid loses focus.

Most importantly, however, is the fact that the download now contains 3 versions of the library:

an ANSI non-threadsafe version
an ANSI threadsafe version
a UNICODE non-threadsafe version (for testing purposes only at the moment).

If the unicode version proves to be stable then a 4th version will be forthcoming; a UNICODE threadsafe...

Neat.

Thank you for following up on that!

I've download the new version.
Now I get the error, that 'egrid_containerID()' is missing.

Thorsten, this function is no longer exported because with all the added commands, I could see no need for it. I can't think why you'd want the controlid of the container gadget?

Anyhow, here's a workaround:

Code: Select all

GetParent_(GadgetID(#egrid)) ;Handle of the container gadget.

Code: Select all

GetDlgCtrlID_(GetParent_(GadgetID(#egrid))) ;The controlid of the container gadget.

I hope this helps.

Thanks! It works, but I don't understand, why it must be removed. With 'egrid_containerID()' it was possibel to use eGrid with other libaries (e.g. PV_Gadgets).

srod · Post by **srod** » Sun Oct 08, 2006 3:26 pm

Ah yes I see. Sorry, forgot about that.

I can reinstate the command for the next version if you'd like. I must admit though that I'd rather keep it out as it encourages some 'dodgy dealings' where an egrid is concerned and if such code breaks the lib, then I cannot really be held to account!

Did someone say "dodgy dealings"

I'm in!

srod · Post by **srod** » Sun Oct 08, 2006 3:40 pm

Aye, there's always an aussie around when there's 'dodgy dealings' afoot!

hehe.

I think all 'PureVisionXP'-User would be glad, if you add 'egrid_containerID()' again.

srod · Post by **srod** » Sun Oct 08, 2006 3:55 pm

Ok, but it was never really documented anyhow. I think I made one mention of it in a much earlier version of egrid.

I will reinstate it. In the meantime, just create your own procedure named egrid_ContainerID() and using the above workaround etc.

Agreed. Thanks srod for keeping on top of it! I'm looking forward to trying it.

You're welcome.

btw, I have fixed the gridline alignment problem - turned out to be easier than I thought!

The fix will only work if you use a custom header with an egrid as I have no control over the placement of the gridlines or the painting of a standard Windows header.

Will upload new versions tomorrow afternoon.
