The best way to do what you want to do is with indicators. Assuming you have your text control is named m_stc, you would set an indicator for an entire line like this: int errorIndicNo = 8; //or any number between 8 and 32 m_stc->IndicatorSetStyle(errorIndicNo ,wxSTC_INDIC_SQUIGGLE); //or whatever s...

You can use the Rotate method to add a rotation factor to the matrix . Just remember that when dealing with matrices, the order of operation matters. For example, this code: mat.Translate(50, 50); mat.Mirror(wxVERTICAL); mat.Rotate(45*3.14/180); dc.SetTransformMatrix(mat); dc.DrawText("Hello",0,0); ...

Are you sure it's not a manifest issue as in this thread?

In addition to the above, you can use a transformation matrix for the DC itself without wrapping it into a graphics context first. For example to mirror across the line x =50, you could do something like wxAffineMatrix2D mat = dc.GetTransformMatrix(); mat.Translate(50, 0); mat.Mirror(); dc.SetTransf...

You probably just need to use the scope operator. ie use ::GetTopWindow() to call the global function instead of class method with the same name.

You need to bind the event handler directly to the control like so: m_staticBitmap->Bind(wxEVT_MOUSE_CAPTURE_LOST, &ImageDialog::OnMouseCaptureLost, this); Replace 'm_staticBitmap' with the name of the control you're actually using. Also, the event type that the event handler will receive is wxMouse...

EVT_MOUSE_CAPTURE_LOST is not a mouse event. It is generated by the wxWindow class. However, it's a more obscure event, so it is not listed in wxFormbuilder with the other window events. To handle that event, you should use the Connect or Bind methods to add a handler for it in the constructor for ...

I think wxDynamicCast uses the wxWidgets RTTI system. So in order to be able to cast to that class type you have to use the wxDECLARE_DYNAMIC_CLASS/wxIMPLEMENT_DYNAMIC_CLASS or wxDECLARE_ABSTRACT_CLASS/wxIMPLEMENT_ABSTRACT_CLASS macros to make that class type known to the RTTI system. As the docs sa...

Correct me if I'm wrong, but it seems to me that wxWidgets is like an extensive "Additional language" of its own, largely defined in these Macros? I don't think so - at least not more so than any other c/c++ library of moderate size. As PB said, if you use the newer Bind method for event handling, ...

I guess I misunderstood. The macro definitions used by wxWidgets are going to be distributed over hundreds of files and many of them are going to be buried in multiple #if or #ifdef statements. So I wouldn't go looking for most of them. If you're new to c++ and wxWidgets you should just focus on wha...

That depends on your compiler. With gcc, you can use the -E option to run the preprocessor and expand all the macro definitions. With visual c++, you would use the /P switch. I'm sure there is a similar option for clang, but I'm not sure what it is. Just a word of warning though, when you run the pr...

Like PB said, this appears to be a manifest issue. Try adding an rc file containing at least the line:
That will include the standard wxwidgets manifest file in your project.

Here's one approach for drawing a dragable curve on a panel. The idea is to keep track of the points in a vector and handle the mouse events for adding or dragging points. // For compilers that support precompilation, includes "wx/wx.h". #include "wx/wxprec.h" #ifdef __BORLANDC__ #pragma hdrstop #en...

I just answered a similar question on stack overflow. Here's a screenshot that shows where to add the 2 extra libraries in codeblocks:

I would expect the points to be an array or vector but I dont think it is. So how do I put multiple values in a wxPoint * You can allocate them with the new operator wxPoint* myArray = new wxPoint[n]; for (size_t i=0;i<n;++i) { myArray[i].x=...; myArray[i].y=...; } wxRegion myRegion(n,myArray); //d...
