Any news to share about the subject?
I am gonna try wxReportDocument and see if I can extend it.

TIA.

I completely missed that these methods are virtual and probably was made like that for this reason.
Thank you.

I use a sub-classed wxControl , and I need to update the drawing inside that sub-classed control according to the background and foreground colors. So if later I use mySubClassedControl.SetBackgroundColour() or mySubClassedControl.SetForgroundColour() , then how do I know inside the sub-classed cont...

Hello,
I need to know where to intercept the background and forground color changes of a control.
Is there an event I don't know about?
What is the best way to do it?

TIA.

Yeah, that's what I thought, because I have searched everywhere.
I can't convince Vadim either to implement it, because the philosophy to add something to wxWidgets is when it is needed by the toolkit itself, not user code.

Thank you for the hint.

Hello,
getting the HBRUSH handle from a wxBrush is easy. But I need to do the inverse, that is create a wxBrush from an existing HBRUSH.
Is it possible? Show me.
TIA.

Better come late than never. 3) perform some action when a video in on a specific second/interval of time This is possible using wxVLC: The static function: void OnPositionChanged_VLC(const libvlc_event_t *event, void *data) { wxVLCFrame *mainFrame = ((wxVLCFrame *)wxGetApp().GetTopWindow()); mainFr...

If the flags contain wxPATH_MKDIR_FULL flag, try to create each directory in the path and also don't return an error if the target directory already exists.

My bad, I haven't read that description to the end.

wxFileName::Mkdir() with wxPATH_MKDIR_FULL flag can help with that Thank you, wxFileName::Mkdir with wxPATH_MKDIR_FULL flag is really handy, the question is: should I test for that directory existence before!? using wxDirExists or it is done internally in wxFileName::Mkdir implementation! I need to...

Hello, When creating a file using wxFileOutputStream and the directory in which this file will be created doesn't exist in the first place, then wxFileOutputStream::IsOk will return false and the file won't be created of course. Is this the intended behavior? because nothing is said in the documenta...

Hello, I need to call wxDir::GetAllFiles for multiple filespec criterias, I thought about calling it multiple times for each filespec criteria since from the documentation it preserves the old content of wxArrayString * files , but this will imply performance issues, because the traversal will be re...

I mean something more straightforward: wxArrayString arrStrFileNames; arrStrFileNames.assign(vStrFileNames.begin(), vStrFileNames.end());//from std::vector<> std::vector<wxString> vec(arrStrFileNames.begin(), arrStrFileNames.end());//from wxArrayString I completely missed that. Thank you again.

Both class provide iterators so you can use them to create another container. I just figured it out: std::vector<wxString> vStrFileNames; wxArrayString arrStrFileNames; for (wxArrayString::const_iterator it = arrStrFileNames.begin(); it != arrStrFileNames.end(); ++it) vStrFileNames.push_back(*it); ...

Hi, The strings vector seems much easier. Also, depending on the scenario you might use const vector... Thank you. I completely forgot about const , also there are situations where I need to convert from a wxArrayString to an std::vector and vice versa, so are there any predefined helper macros to ...

Why are you want to use reference and not value type? You can share vector via wxSharedPtr<> instead or not share anything at all.

I need a list of wxString or wxFileName to be passed as a function parameter.
