TGX11 Class Reference

This class is the basic interface to the X11 (Xlib) graphics system.

It is an implementation of the abstract TVirtualX class.

This class gives access to basic X11 graphics, pixmap, text and font handling routines.

The companion class for Win32 is TGWin32.

The file G11Gui.cxx contains the implementation of the GUI methods of the TGX11 class. Most of the methods are used by the machine independent GUI classes (libGUI.so).

This code was initially developed in the context of HIGZ and PAW by Olivier Couet (package X11INT).

AddPixmap()

Int_t TGX11::AddPixmap ( ULong_t  pixid, UInt_t  w, UInt_t  h  )

virtual

Parameters

[in]	pixid	Pixmap identifier
[in]	w,h	Width and height of the pixmap

register new pixmap

Definition at line 1377 of file TGX11.cxx.

AllocColor() [1/2]

Bool_t TGX11::AllocColor ( Colormap  cmap, RXColor *  color  )

protected

Allocate color in colormap.

If we are on an <= 8 plane machine we will use XAllocColor. If we are on a >= 15 (15, 16 or 24) plane true color machine we will calculate the pixel value using: for 15 and 16 bit true colors have 6 bits precision per color however only the 5 most significant bits are used in the color index. Except for 16 bits where green uses all 6 bits. I.e.:

15 bits = rrrrrgggggbbbbb
16 bits = rrrrrggggggbbbbb

for 24 bits each r, g and b are represented by 8 bits.

Since all colors are set with a max of 65535 (16 bits) per r, g, b we just right shift them by 10, 11 and 10 bits for 16 planes, and (10, 10, 10 for 15 planes) and by 8 bits for 24 planes. Returns kFALSE in case color allocation failed.
