I think I have found another glitch... possibly in my code, but I don't think so.

I have two columns, one with checkboxes, one with names. Sometimes when I press the space bar is checks the PREVIOUSLY selected rows checkbox, not the currently selected row.

This behaviour is spuradic, and as I type this I can not reproduce it. Encountered this before?

It seems like cursor pos is not changed in some rare situations. Could you post your test case? And what version of grid do you use?

I am using the version bundled with UPP-2007.1, I am not exactly sure what the version number is. Judging from the changelog I would say 2007.1rc3?

I will try to find a some simple test code / instructions to replicate as I finish updating my code to use GridCtrl.

As I recall it is when selections are made using a combination of the mouse (to enter GridCtrl), then using <enter> and <space> to make selections. As I said, I do not recall the specific sequence.

Now that a few little bugs have been ironed out it seems like GridCtrl will accomplish what I need. Nice work!!

Except one (hopefully easy) thing: how can I disable one row? Or, at the minimum, one cell which I just inserted?

Verbal example: I have a gridctrl with a column of check boxes and a column of names, when I populate (as I Add(sql result vector)) the grid I need to disable some checkboxes. I tried calling NoEditable and NoClickable with no luck.

Is there an easy way to achieve this?

Thanks,
Robert

Generally NoEditable should prevent creating embeded control. However it works well before the window with grid is displayed. Later GridCtrl::Add(..) call SyncCtrls() (method responisble for creating/updating embeded controls) immediately after creating row. You have to call Add() before NoEditable() which does not update controls' positions and you still see them able to be edited. So as a workaround make SyncCtrls() in GridCtrl class public and call it after adding rows and making some of them uneditable. I'll try to find correct solution to this problem before new dev release (Add()/AddRow() call SyncCtrls and I would like to avoid clling it a second time in NoEditable() somehow).

There were some important changes/bugs fixed after it. So I will make current snapshot of GridCtrl available on this forum today. Please check it.

I know calling SyncCtrls in NoEditable is less than ideal... but is something similar not the 'cleanest' solution?

What about creating some type of 'stripped' SyncCtrls that only affects the row being set to NoEditable?

This still does not quite look right. The Ctrl is not getting totally disabled (it still displays and is sometimes able to be checked). I think the SyncCtrls function needs a small tweak. I think if the row is set to NoEditable the Ctrl should be disabled. What are your thoughts on that?

kcabobert, this thread starts to be confusing, dealing with ArrayCtrl and GridCtrl without specification.

Please at least add "ArrayCtrl" or "GridCtrl" somewhere in your post Smile

Or start a new one...

Yeah, I thought about that... it sort of took a turn for the confusing.

Basically the thread focuses on GridCtrl after about the fourth post, with occasional references to ArrayCtrl after.
