I cant test here but something like thatshould work : class MyClient : public wxMDIClientWindow{ protected: DECLARE_EVENT_TABLE() void OnEraseBg(wxEraseEvent& event); ... }; void MyClient::OnEraseBg(wxEraseEvent& event){ event.GetDC().DrawImage(...); // Blit your image directly. } BEGIN_EVENT_TABLE(...

As said in the wxMDIParentFrame doc [1], you must derive wxMDIClientWindow to implement your background paint and override wxMDIParentFrame::OnCreateClient to explicitly use your own wxMDIClientWindow class. [1] : http://www.wxwidgets.org/manuals/2.6.3/wx_wxmdiparentframe.html#wxmdiparentframeoncrea...

wxPaintEvent is sent to the window to repaint and not to its parent, so if you want to redraw child client area, you must intercept draw event for wxMDIClientWindow. You just have to overide wxMDIClientWindow and intercept wxPaintEvent as you do but for wxMDIClientWindow derived class. Note that wxP...

What is your plateform and wx version ?

Please dump the code of the function where you use SelectObject call.

Is it really wxDC::SelectObject or wxMemoryDC::SelectObject ?
Please dump the code of your function.
And if it is not shown in your code, precise the color mode of your bitmap.

Ok, I hadnt tested it on wxGTK (it must do it a day), I only use that on Windows and it work perfectly.

When you create a wxFont object, you can set a font face like "webdings" or "wingdings" (or what you want).
This fonts are symbol-oriented, you can use it to draw such symbols.

Yes you can, but - as all text software - you must change the font you use. If you select a symbol font (1& 2) and use it with wxDC::DrawText, the text is writted with symbols. 1 : http://www.wxwidgets.org/manuals/2.6.2/wx_wxfont.html#wxfont 2 : http://www.wxwidgets.org/manuals/2.6.2/wx_wxdc.html#wx...

The DPI (1) is a standard "density of point" measure. For the screen, we must speak about PPI (2) "Pixel per Inch" that is generally 72, 96 or 144.

You can use the bool PopupMenu(wxMenu* menu, const wxPoint& pos = wxDefaultPosition) with the wxDefaultPosition at third param, it will automatically place the menu at mouse position. And if you really want to show your menu at the right side of the item, you can use wxTreeCtrl::GetBoundingRect [1] ...

This is the normal C++ definition.
When a base-class function is declared as virtual, all overriden implementation are virtual. With or without the virtual keyword.

If you want a function with the same prototype but not virtual, you must change its name.

Oh, excuse-me, as I see you write thread1->Run(); thread2->Run(); I think you wana use many threads. What I want to say is you count all thread you run and when it finish, you decrement. When the count is zero, you can exit the app. The wait function can not work as you use it because wxThread::wait...

You probably can not capture all the wxTextCtrl canva because, it probably dont store it completly.

IMHO, the wxTextCtrl (and all its specific implementation) use a local drawing function so if you want to draw it, you must paint it yourself based on the wxTextCtrl text-style infos.

Hello.

As thread are based on the same class, why don't you put a static counter of running thread with one or two functions to access it (with mutexes) in order to count how many thread is running and you can wait (while) until all thread have returned.

What about use a wxStringTokenizer [1] to separate substrings and use wxString::ToDouble [2] to translate on double.
