[wxlua-users] wxGrid and wxPrint help

[É. Ő. <ejj...@gm...>]

Hi!
My previous e-mail went to a wrong topic, sorry. again:
I have a little problem.. My application loads the GUI from the xrc file
generated by DialogBlocks. I am using wxGrid-s, which are work very well -
except I can't re-size them. Once I called grid:CreateGrid(rows,cols), I
can't use this call again (I can, but no result). I tried
grid:ClearGrid(), grid:Refresh(), but no result..
The second SetGridCursor problem has been solved, I used that from an
another event, wx.wxEVT_KEY_UP.
I have a report now too: seems wxGrid doesn't check the row and the column
in SetCellValue(), because when I used that with negative rows, it throw me
an unhandled exception window (well, now I have more unhandled exception
related to wxGrid, but I haven't found out, what caused that till now...).
The first problem has been 'patched' now: I know how many columns I want to
add, so I check it:
if grid:GetNumberRows() < iRows then
grid:AppendRows(grid:GetNumberRows()-1,iRows-grid:GetNumberRows()) end
But I think there must be a more elegant solution :)

Another problem that I have to print with my application. But the firm I
write this app, use an old matrix printer, which prints to 'pull-out' (or
fanfold? web-tranlslation, I hope it's correct. Here is a page about it:
http://shop.unas.hu/shop_ordered/5207/shop_pic/termek_820145.jpg) paper. The
samples I found can print pictures, and everything else, but I need just
charaters, because the old program used just simple characters to draw a
table. (But that used a .prn file too... :-/). So, I want to print just
characters, and make some text's font bold and maybe bigger on it, that's
all.
I hope somebody can help me in this.
