Re: Window layout question
OK, thanks. Pity, it would have looked great. I'm not keen on trying to split it, as I can imagine it would be a nightmare keeping the bits together in all situations.

Window layout question
All, I currently have a main window which looks like this: p1.png I would like to add a logo in the top right, thus: p2.png The idea is to occupy both unused toolbar space and unused notebook space. I'm guessing it's not possible to do this with sizers. I have tried creating the logo window as a chi...

Re: wxGrid scrolling refresh problem with merged cells
Returning wxGridCellAttr objects with zero / negative sizes for the covered cells did the trick. All works OK now.

Re: wxGrid scrolling refresh problem with merged cells
So, having gone and read the source code for wxGrid::SetCellSize , wxGrid::DrawGridCellArea and wxGridCellAttr::SetSize it would seem that this comment in the last of those three functions may hold the key: If this cell is larger (2,2) then this is the top left cell the other cells that will be cove...

Re: wxGrid scrolling refresh problem with merged cells
Not sure which specific "two things" you are referring to there, but never mind. Thanks for your time.

Re: wxGrid scrolling refresh problem with merged cells
It's a redraw issue. Fixes itself if I minimize and maximize the window. Should have mentioned that, sorry. The point really is that it was fine but slow with my original method, which suggests there ought to be some way to make it work with the more efficient approach.

Re: wxGrid scrolling refresh problem with merged cells
Hi doublemax Could you elaborate a bit, please? I know the cell size is part of wxGridCellAttr as I am setting it. How might it "get lost" between initial display—which is just fine—and scrolling, when other features such as the background colour and alignment survive just fine? The cell s...

wxGrid scrolling refresh problem with merged cells
Hi all, I'm using wxWidgets 3.0.2 on Windows 7. I have a C++ application that has a potentially very large spreadsheet-style grid. I'm in the process of recoding the handling of attributes as I was having serious performance issues when the 18-column grid held several thousand rows—it was taking up ...

"Save As" lowers document window
I'm having a problem with my MDI wxWidgets application (under development in Visual Studio 2013 on Windows 7), which I have found to be simple to reproduce in the docview sample. Specifically, if you open two documents, say a.txt and b.txt, then "Save As..." b.txt to a different path, the ...

Re: wxGraphicsContext::DisableOffset
Hi doublemax, My code works with double coordinates. I probably didn't explain very well that I'd understood already what the problem was, but I really don't want wxGraphicsContext to attempt to automatically apply the half-pixel offsets when stroking a path. I expect to have full control over that ...

wxGraphicsContext::DisableOffset
Hello all, In my first ever wxWidgets project, I'm creating a standalone desktop application from a browser-based prototype. A lot of the work involves porting JavaScript code for drawing on an HTML Canvas to C++ code drawing on a wxGraphicsContext. Today I spent several hours trying to figure out w...
