Detailed Description

A GdkBitmap C++ wrapper class.

Bitmap, like Pixmaps are offscreen drawables. They can be drawn upon with the standard drawing primitives, then copied to another drawable (such as a Gdk::Window) with Gdk::Pixmap::draw(). The depth of a pixmap is the number of bits per pixels. Bitmaps are simply pixmaps with a depth of 1. (That is, they are monochrome bitmaps, each pixel can be either on or off).

Note: dynamically allocated objects must either be unreferenced or assigned to a smart pointer. Stack objects are automatically unreferenced when they go out of scope.

Constructor & Destructor Documentation

Xfc::Gdk::Bitmap::Bitmap (  GdkBitmap *  bitmap, bool  owns_reference = true )  [explicit, protected]

Construct a new Bitmap from an existing GdkBitmap. Parameters: bitmap  A pointer to a GdkBitmap. owns_reference  Set false if the initial reference count is floating, set true if it's not. The bitmap can be a newly created GdkBitmap or an existing GdkBitmap. (see G::Object::Object).

Xfc::Gdk::Bitmap::Bitmap (  const char *  data, int  width, int  height )

Create a new bitmap from data in XBM format using the root window to determine the default values. Parameters: data  A pointer to the XBM data. width  The width of the new bitmap in pixels. height  The height of the new bitmap in pixels. Bitmap is created with a reference count of 1 that the caller owns.

Xfc::Gdk::Bitmap::Bitmap (  const Window &  window, const char *  data, int  width, int  height )

Create a new bitmap from data in XBM format using window to determine the default values. Parameters: window  The window to use. data  A pointer to the XBM data. width  The width of the new bitmap in pixels. height  The height of the new bitmap in pixels. Bitmap is created with a reference count of 1 that the caller owns.
