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. Best regards: Attila

You need to send a wxGridTableMessage to the wxGrid to notify it that changes have been made. Search for wxGridStringTable::InsertRows(...) and see the code where it creates a new wxGridTableMessage to send to the wxGrid. You need to duplicate this. http://svn.wxwidgets.org/viewvc/wx/wxWidgets/branches/WX_2_8_BRANCH/src/generic/grid.cpp?view=markup See also "class WXDLLIMPEXP_ADV wxGridTableMessage" here. There isn't much documentation for this, but you can figure it out from the wxGridStringTable::Insert/Append/Delete/Rows/Cols() functions above. http://svn.wxwidgets.org/viewvc/wx/wxWidgets/branches/WX_2_8_BRANCH/include/wx/generic/grid.h?view=markup In the past I have written a function called UpdateGrid() (don't know where it is anymore) that gets the current number of rows/cols from the wxGrid and the number of rows/cols from my wxGridTable and sends the wxGridTableMessages as appropriate. Once you have this function you can adjust your wxGridTable as you like and then call the UpdateGrid() function to sync the wxGrid to the table. I recommend this method as opposed to duplicating the separate Insert/AppendDelete/Rows/Cols functions. > 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 :) Unfortunately not, there are checks in the wxWidgets C++ code that will assert rather than cause an exception in the debug compiled version of wxWidgets. Perhaps I should release a binary build of wxLua compiled with the debug settings? I would rather not have to add checks for proper values to the inputs of the wxWidgets functions since there will be need to be thousands of them and that would really bloat wxLua. > --- > > Another problem that I have to print with my application.

Printing in wxWidgets is done by using a wxPrinterDC that is created by the printing framework itself. I assume you've looked at the printing.wx.lua sample. You need to replace the function DisplayFigure() with your own drawing code. You will need to use wxC::DrawText(), wxDC::GetTextExtent() and friends along with all the PPI and page size info used in the function printOut:OnPrintPage() in printing.wx.lua. You may also want to look into wxHTMLEasyPrinting, which will be able do the layout for you, but I have never used it very seriously. Regards, John

My problem has been partially solved - wxHtmlEasyPrint works perfect. I have
to print checks and bills, html format is the best solution, easy to
generate it form grid cells. But after the preview, when I exit from the
application, it shown MS's error reporter window, so my app detected a
problem, please inform MS about it... It happened after I added these few
lines:
local hep = wx.wxHtmlEasyPrinting("Nyomtatás",MyApp)
local prnSetup = hep:GetPageSetupData()
local prnData = prnSetup:GetPrintData()
prnData:SetNoCopies(iOldalak) -- I want to set here how many pages to print.
local tMinoseg =
{wx.wxPRINT_QUALITY_DRAFT,wx.wxPRINT_QUALITY_LOW,wx.wxPRINT_QUALITY_MEDIUM,wx.wxPRINT_QUALITY_HIGH}
prnData:SetQuality(tMinoseg[tSettings["minoseg"]])
prnSetup:SetPrintData(prnData)
hep:PreviewText(sHTML)
After I close the preview window, seems everything is ok, but the error
comes after I shotdown the whole application...
By the way, is there any way to translate the preview dialog? The buttons
aren't translated. Same with DatePickerCtrl, even if I used
os.setlocale("","time")
Thanks in advance:
Attila
Sorry for writing again, I don't want to hurry anybody, but my application is almost ready, and I was unable to fix this error. Any ideas?

Can you post the simplest, runnable, code possible that demonstrates
this to help me debug it? The one thing to be careful about is making
sure that you don't use the local keyword for something that you need
to exist beyond the function it was created in.

I do not know much about internationalization, but this may help.

Thanks for the reply, here is a code which demonstrate the error:
require "wx"
myApp = wx.wxFrame(wx.NULL,-1,"Testing
HtmlEasyPrinting",wx.wxDefaultPosition,wx.wxSize(200,100))
btn = wx.wxButton(myApp,-1,"Press me")
btn:Connect(wx.wxEVT_COMMAND_BUTTON_CLICKED,function(event)
sHTML = [[<html><body>Please close this preview. After you closed, and you
want to exit from the application, it will throw an error.</body></html>]]
hep = wx.wxHtmlEasyPrinting("My print's preview",myApp)
hep:SetHeader("@PAGENUM@/@PAGESCNT@. page")
prnSetup = hep:GetPageSetupData()
prnData = prnSetup:GetPrintData()
prnData:SetNoCopies(3)
tMinoseg =
{wx.wxPRINT_QUALITY_DRAFT,wx.wxPRINT_QUALITY_LOW,wx.wxPRINT_QUALITY_MEDIUM,wx.wxPRINT_QUALITY_HIGH}
prnData:SetQuality(2)
prnSetup:SetMarginTopLeft(wx.wxPoint(12,12))
prnSetup:SetPrintData(prnData)
hep:PreviewText(sHTML)
end)
myApp:Connect(wx.wxEVT_CLOSE_WINDOW,
function(event)
myApp:Destroy()
wx.wxExit(0)
event:Skip()
end)
myApp:Centre()
myApp:Show(true)
wx.wxGetApp():MainLoop()
Hope this helps (I made everything global, so this can't be the problem)
I found the problem now, and fixed it:
hep = wx.wxHtmlEasyPrinting("My print's preview",myApp)
hep:SetHeader("@PAGENUM@/@PAGESCNT@. page")
prnSetup = hep:GetPageSetupData()
prnData = hep:GetPrintData()
prnData:SetNoCopies(3)
tMinoseg =
{wx.wxPRINT_QUALITY_DRAFT,wx.wxPRINT_QUALITY_LOW,wx.wxPRINT_QUALITY_MEDIUM,wx.wxPRINT_QUALITY_HIGH}
prnData:SetQuality(2)
prnSetup:SetMarginTopLeft(wx.wxPoint(12,12))
This works as it excepted, everything is OK now, no crash :-)
I found another "fix" too.
Do NOT ever use "wx.wxExit(0)" to close wxWidgets apps. There are a
lot of things going on behind the scenes for GUI apps and you should
call wxFrame::Destroy() if you want to close the app nicely, see also
wxApp::ExitMainLoop(). In fact, your event handler for
wx.wxEVT_CLOSE_WINDOW does nothing useful and you should remove it.
Regards,
John
