Thank you, that info is very useful.

Yes, this is under Windows. The problem is that we have a government customer that needs to know if/how/when our software modifies the registry, and "maybe" is not an answer that they will accept. So, is the "last used directory" stored in the registry somewhere (I haven't been able to find it), or ...

When running a program that uses a wxFileDialog, the dialog seems to somehow "remember" the directory accessed most recently, and uses that directory as the new "current" location. Furthermore, it remembers this even after the program is shut down and restarted. While this is a pretty cool "feature"...

As I said, you seem to be confused about the purpose/intent of wxGridCellEnumRenderer. Yes, I HAVE read the documentation. For example, the documentation for wxGridCellEnumRenderer states : This class may be used to render in a cell a number as a textual equivalent. The corresponding text strings ar...

Thank you for the wonderful (but irrelevant) reference on enums, but I am quite aware of what an enum is - and it has very little to do with the issue at hand. If wxGridCellEnumRenderer is supposed to render a digit instead of the text associated with that digit (as you seem to think), then why woul...

It doesn't seem like you quite understand the issue. wxGridCellEnumRenderer does NOT work correctly on a wxGrid, UNLESS you either : 1) derive a new class from wxGrid and override the CanGetValueAs() and GetValueAsLong() methods 2) derive a new class from wxGridCellEnumRenderer and override the Draw...

Ticket #18336 created for this issue.

No, that doesn't really work, I think you need to examine that a bit more closely. The editor part works fine, but once you edit the cell (and then move on to some other cell), you are left with a "digit" in the cell instead of the actual words. In your case, the cell starts out with a word, only be...

Well, I thought that I could simply override GetString(), unfortunately, GetString is not defined as virtual in wxGridCellEnumRenderer.

So, I guess that I will have to override the whole Draw() method instead. This is getting messier each step of the way.

After further investigation, I have found what I think to be the problem. The code for wxGridCellEnumRenderer::GetString is as follows: wxString wxGridCellEnumRenderer::GetString(const wxGrid& grid, int row, int col) { wxGridTableBase *table = grid.GetTable(); wxString text; if ( table->CanGetValueA...

I can't seem to get wxGridCellEnumRenderer to do anything. Perhaps I am missing an important step? I want to have the user choose between options of "Left", "Right", "Up", or "Down", and have the cell rendered as such (with the "actual" cell values being 0,1,2, or 3. This seems to be what the wxGrid...

Yeah, that's what I suspect that I'll end up doing.

It just seemed simpler at first glance to use a wxGrid, since it had everything I needed, except for single cell selection.

Thanks.

Basically, I want to show a "grid-like" widget that has a programmable number of boxes. Each box represents an item in the world from 1 to N. When the user clicks on a box, a frame to the right will be displayed containing the data associated with that item. The user can then view and/or edit that d...

Well, there could be anywhere from like 20 to 2000 (and I won't know how many until runtime). I thought that by using the wxGrid I could gain a lot of functionality (like scrolling if needed). It seems that wxGrid has MORE than what I need, I just want to enforce the "one-selected-cell-only" rule. T...

1) Is there some way to disable all group selection functions? I want to disallow the user from ever having more than one cell selected. For my purposes, the selected cell is the "active item", and it makes no sense for there to be more than one active item. 2) Is there some way to change the color ...
