wxWidgets Discussion Forum

The easiest way is to use wxString::Format which takes a printf style format specification and returns a wxString.

For example:

Thank you for looking into this and posting the results of your work here, it is certainly useful. ...and all references to wxXMLNode->GetProperty(... to wxXMLNode->GetAttribute(.... That will allow you to compile the code. Do you mean change all references to wxXMLNode->AddProperty(... to wxXMLNode...

It isn't in any way related to wxWidgets, but one of the best tools for this job is Jasper Reports.

I wish that there was a wxWidgets equivalent, but I think that it would be a huge project and wxReportDocument is probably as close as we will get.

Hi, AFAIK this is still unfixed and the trac ticket remains opened.

Yes it says that the wxWidgets DLL cannot be found.

As Doublemax says, either copy it to the directory where your executable (.EXE) file is. Or perhaps better is to add the directory with your wxWidgets DLLs to the PATH environment variable.

It might be better for you to use a wxGrid here?

I tested this on Linux (gcc 4.8.4) and it draws the label on 2 separate lines. doublemax: I assume that wxfreechart uses wxDC::DrawText to draw the label which only supports multi-line texts since wx 2.9.2 Yes it does, although in the OP's case I expect the label is appearing vertically, so it is dr...

... and what is the problem you are having, and which database are you using (may or may not be relevant)? SELECT student_code, name FROM students WHERE marks = (SELECT MAX(marks) FROM students GROUP BY subject_code); For a start, the GROUP BY clause is probably redundant because MAX(marks) should o...

Just in case you haven't already found it there is an 'automatic' way of providing this functionality.

See WX Persistent Objects Overview.

Concerning the "wxFreeChart", is still maintained? No, it is not actively maintained. PB and myself have made some recent changes to fix bugs and improve performance, but no real active development work. That said, depending on what you need, it does what it does quite well and is documented. Also ...

If you are using a newer version of wxWidgets (I think >= 3.0) and you want to use wxFreeChart, then you might like to try this version which has some bug fixes:

Both Nautilus and the GTK native wxDataViewListCtrl behave as I expected (and consistently with each other), i.e. the selection remains with the item following a sort. The only difference from MSW File Explorer is that multiple selections are maintained following a sort on GTK, whereas the selection...

What is the behavior of the native control under GTK/Cocoa? Unfortunately I am not in a position to check that for a few days. However, the behavior of the (native) wxListCtrl and the listctrl sample on MSW is as I would expect, i.e. the selected item remains selected - because the selected row fol...

What should be the action item, I feel it is a bug.

I agree. I can raise a ticket in trac, but first I would like to take a look at the problem and see if there is a fix I can propose and make a patch.

If you resort the control you selection should stay. You didn't explicitly ask for a selection change. Actually, this is exactly the point, no selection change was requested but the control selected a completely different item (that just happens to now be in the same position as the previously sele...
