Summary0023660: TStringGrid option goAutoAddRows has restricted functionality
DescriptionASAICS the auto-add rows only adds rows if (a) the existing last row has at least one non-empty cell and (b) the user uses the down-arrow key to attempt to move down. The following use cases need to be dealt with:

1. The user wishes to ensure the grid has all the rows needed before entering data. In this case it should be possible to add rows irrespective of whether the last row has a non-empty cell.

2. The user wishes to use tab rather than arrow keys for navigation. A new row should be added if auto advance is set to right and down (or laft and down) and the user presses tab at the appropriate end of the row. A new row should also be added if auto advance is set to down and the user presses tab anywhere on the last row.

3. The user wishes to use the mouse for navigation. If the user clicks on the space below the last row and the cursor is not on the last row it will move down to the last row. It may seem intuitive to the user that if the cursor is already on the last row another row should be added and the cursor moved to that. This last case is more marginal but should be considered.

Can you check with r39864.
I implemented using Tab key for goAutoAddRows option.

It only works if goTabs is in options.
And it only adds a row when you are in the last cell (which I think is more intuitive, it behaves just like editing tables in MS Word or OpenOffice).

If this part is OK I will implement the "don't bother if the row is empty or not" issue.

I won't implement the "mouse-part" of this request.

Hi, Bart. I can't find r39864; there seems to be no issue with that number. Is it a patch?

I have goTabs set but it doesn't add rows. However I'm using the standard 1.0.4 for deb package so perhaps it hasn't worked through to the release yet.

I agree about intuitive in the last /row/ (not necessarily the last /cell/, the user might not have data for all the cells so no cause to go to a specific one). There is a possibility that aaLeftUp or aaRightUp might be set so the user could try to tab upwards. However I think that can be treated as too pathological a case to implement; it would certainly be be trickier.

It is a SVN revision. You can download the development version and compile Lazarus yourself.

In r39938 I implemented goTabIgnoreAutoAdvance option.
If set (and goTabs in Options), then Tab key traverses grid like in aaRightDown mode, much like tables in common wordprocessors.

@Ian: you can try a snapshot from (deb file) and test. With todays snapshot you can test the "Tab adds a Row" feature.

I introduced the goIgnoreRowContentForAutoAddRows option in r39940.
If set then AutoAddRows will add a row even if last row is empty.
The then added row will not be removed if it is empty when user moves the cursor up.

Please test and close if OK.
