Detailed Description

- - -The TQGLColormap class is used for installing custom colormaps into -TQGLWidgets. - -

- - -

TQGLColormap provides a platform independent way of specifying and -installing indexed colormaps into TQGLWidgets. TQGLColormap is -especially useful when using the OpenGL -color-index mode. -

Under X11 you must use an X server that supports either a PseudoColor or DirectColor visual class. If your X server -currently only provides a GrayScale, TrueColor, StaticColor or StaticGray visual, you will not be able to -allocate colorcells for writing. If this is the case, try setting -your X server to 8 bit mode. It should then provide you with at -least a PseudoColor visual. Note that you may experience -colormap flashing if your X server is running in 8 bit mode. -

Under Windows the size of the colormap is always set to 256 -colors. Note that under Windows you can also install colormaps -in child widgets. -

This class uses explicit sharing (see Shared - Classes). -

Example of use: -

-    #include <qapplication.h>
-    #include <qglcolormap.h>
-
-    int main()
-    {
-        TQApplication a( argc, argv );
-
-        MySuperGLWidget widget( 0 ); // A TQGLWidget in color-index mode
-        TQGLColormap colormap;
-
-        // This will fill the colormap with colors ranging from
-        // black to white.
-        for ( int i = 0; i < colormap.size(); i++ )
-            colormap.setEntry( i, qRgb( i, i, i ) );
-
-        widget.setColormap( colormap );
-        widget.show();
-        return a.exec();
-    }

Member Function Documentation

TQGLColormap::TQGLColormap () -

-Construct a TQGLColormap. - -

TQGLColormap::TQGLColormap ( const TQGLColormap & map ) -

-Construct a shallow copy of map. - -

TQGLColormap::~TQGLColormap () -

-Dereferences the TQGLColormap and deletes it if this was the last -reference to it. - -

void TQGLColormap::detach () -

-Detaches this TQGLColormap from the shared block. - -

TQColor TQGLColormap::entryColor ( int idx ) const -

-Returns the TQRgb value in the colorcell with index idx. - -

TQRgb TQGLColormap::entryRgb ( int idx ) const -

-Returns the TQRgb value in the colorcell with index idx. - -

int TQGLColormap::find ( TQRgb color ) const -

-Returns the index of the color color. If color is not in the -map, -1 is returned. - -

int TQGLColormap::findNearest ( TQRgb color ) const -

-Returns the index of the color that is the closest match to color -color. - -

bool TQGLColormap::isEmpty () const -

-Returns TRUE if the colormap is empty; otherwise returns FALSE. A -colormap with no color values set is considered to be empty. - -

TQGLColormap & TQGLColormap::operator= ( const TQGLColormap & map ) -

-Assign a shallow copy of map to this TQGLColormap. - -

void TQGLColormap::setEntries ( int count, const TQRgb * colors, int base = 0 ) -

-Set an array of cells in this colormap. count is the number of -colors that should be set, colors is the array of colors, and -base is the starting index. - -

void TQGLColormap::setEntry ( int idx, TQRgb color ) -

-Set cell at index idx in the colormap to color color. - -

void TQGLColormap::setEntry ( int idx, const TQColor & color ) -

-This is an overloaded member function, provided for convenience. It behaves essentially like the above function. -

Set the cell with index idx in the colormap to color color. - -

int TQGLColormap::size () const -

-Returns the number of colorcells in the colormap. - - -
