///////////////////////////////////////////////////////////////////////////// // Name: src/motif/dcclient.cpp // Purpose: wxClientDCImpl class // Author: Julian Smart // Modified by: // Created: 01/02/97 // Copyright: (c) Julian Smart // Licence: wxWindows licence ///////////////////////////////////////////////////////////////////////////// /* About pens, brushes, and the m_autoSetting flag: Under X, pens and brushes control some of the same X drawing parameters. Therefore, it is impossible to independently maintain the current pen and the current brush. Also, some settings depend on the current logical function. The m_currentFill, etc. instance variables remember state across the brush and pen. Since pens are used more than brushes, the m_autoSetting flag is used to indicate that a brush was recently used, and SetPen must be called to reinstall the current pen's parameters. If m_autoSetting includes 0x2, then the pens color may need to be set based on XOR. There is, unfortunately, some confusion between setting the current pen/brush and actually installing the brush/pen parameters. Both functionalies are perform by SetPen and SetBrush. C'est la vie. */ // ============================================================================ // declarations // ============================================================================ // ---------------------------------------------------------------------------- // headers // ---------------------------------------------------------------------------- // For compilers that support precompilation, includes "wx.h". #include "wx/wxprec.h" #ifndef WX_PRECOMP #include "wx/log.h" #include "wx/app.h" #include "wx/window.h" #include "wx/dcmemory.h" #include "wx/math.h" #include "wx/image.h" #include "wx/dcclient.h" #endif #ifdef __VMS__ #pragma message disable nosimpint #endif #include #ifdef __VMS__ #pragma message enable nosimpint #endif #include "wx/motif/private.h" #include "wx/motif/dcclient.h" #ifdef __EMX__ #include // for M_PI #endif // __EMX__ #include "bdiag.xbm" #include "fdiag.xbm" #include "cdiag.xbm" #include "horiz.xbm" #include "verti.xbm" #include "cross.xbm" static Pixmap bdiag, cdiag, fdiag, cross, horiz, verti;
