I am unable to attach the file .It is showing an error message (HTTP Error) You could also upload to something like https://www.sendspace.com But if it's that big, it's usually far too much effort to dig throug...

Re: Issue in Capturing Screenshot using wxGraphicsContext

So your code can already render into a wxMemoryDC. Why don't you do that and forget about wxClientDC? Or are you saying that the problem also occurs when rendering directly into a wxMemoryDC? In that case, please provide a minimal compilable sample that shows the issue. I tried to Upload sample Sol...

Re: Issue in Capturing Screenshot using wxGraphicsContext

I'm a little confused that you could change from wxGLCanvas to wxPanel to easily. Do you use OpenGL or not? Please show the code for the paint event handler. Actually, My software Application uses OpenGL. For drawing curves, I am not using OpenGL. so, I have tried in another application which uses ...

Re: Issue in Capturing Screenshot using wxGraphicsContext

//GetCanvasPtr() returns wxGLCanvas My guess is that this is the main problem. When using hardware accelerated OpenGL, the OpenGL window is usually a hardware overlay that doesn't "live" in normal Windows GDI space. (Still assuming that you're under Windows). In addition to that, i don't think mixi...

Re: Issue in Capturing Screenshot using wxGraphicsContext

Platform, wxWidgets version? In any case, it's more reliable to render everything into a wxBitmap through a wxMemoryDC. Just rewrite your render code so that it takes a wxDC& as parameter and you can use it to render on screen as well as into any other device context. Platform:Windows 8, Visual stu...

Re: Issue in Capturing Screenshot using wxGraphicsContext

I think with wxMemoryDC it would be much more straightforward. Just assosiate your xMemoryDC object with wxGraphicsContext and draw anyrhing you want: wxGraphicsContext* gc = wxGraphicsContext::Create(mdc);//mds is wxMemoryDC object if (gc) { //draw here delete gc; } I am actually Creating a wxGrap...

Re: Issue in Capturing Screenshot using wxGraphicsContext

Post some source code maybe? So that we could see whether there is a problem in screen capturing logic. This is how I am capturing Screen: wxClientDC dcScreen(m_pmainwind->GetCanvasPtr()); //GetCanvasPtr() returns wxGLCanvas wxSize WinSize = m_pmainwind->GetCanvasPtr()->GetSize(); //Create a Bitmap...
