Function documentation

void SetupEnvironment()

 Setup Include and Macro paths.
 Since inclusion into ROOT this does nothing but could
 potentially be reactivated if some common macros are established
 and shipped with binary ROOT (in macros/eve). For example, these
 might be used to spawn specific GUI / GL configurations.

void SetupGUI()

 Setup icon pictures and mime-types.

Bool_t CheckMacro(const Text_t* mac)

 Checks if macro 'mac' is loaded.

void AssertMacro(const Text_t* mac)

 Load and execute macro 'mac' if it has not been loaded yet.

void Macro(const Text_t* mac)

 Execute macro 'mac'. Do not reload the macro.

void LoadMacro(const Text_t* mac)

 Makes sure that macro 'mac' is loaded, but do not reload it.

void ColorFromIdx(Color_t ci, UChar_t* col, Bool_t alpha = kTRUE)

 Fill col with RGBA values corresponding to index ci. If alpha
 is true, set alpha component of col to 255.
 ROOT's indexed color palette does not support transparency.

void ColorFromIdx(Float_t f1, Color_t c1, Float_t f2, Color_t c2, UChar_t* col, Bool_t alpha = kTRUE)

 Fill col with weighted RGBA values corresponding to
 color-indices c1 and c2. If alpha is true, set alpha component
 of col to 255.

Color_t* FindColorVar(TObject* obj, const Text_t* varname)

 Find address of Color_t data-member with name varname in object
 obj.

 This is used to access color information for TGListTreeItem
 coloration from visualization macros that wrap TObjects into
 TEveElementObjectPtr instances.

const char* FormAxisValue(Float_t x)

 Returns formatted text suitable for display of value 'x' on an
 axis tick-mark.

Bool_t IsU1IntervalContainedByMinMax(Float_t minM, Float_t maxM, Float_t minQ, Float_t maxQ)

 Return true if interval Q is contained within interval M for U1 variables.
 It is assumed that all values are within the [-2pi, 2pi] interval and
 minM <= maxM & minQ <= maxQ.

Bool_t IsU1IntervalOverlappingByMinMax(Float_t minM, Float_t maxM, Float_t minQ, Float_t maxQ)

 Return true if interval Q is overlapping within interval M for U1 variables.
 It is assumed that all values are within the [-2pi, 2pi] interval and
 minM <= maxM & minQ <= maxQ.
