Member Function Documentation

◆ AssertMacro()

void TEveUtil::AssertMacro ( const char *  mac)
static

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

Definition at line 158 of file TEveUtil.cxx.

◆ CheckMacro()

Bool_t TEveUtil::CheckMacro ( const char *  mac)
static

Checks if macro 'mac' is loaded.

Definition at line 140 of file TEveUtil.cxx.

◆ ColorFromIdx() [1/3]

void TEveUtil::ColorFromIdx ( Color_t  ci,
UChar_t  col[4],
Bool_t  alpha = kTRUE 
)
static

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.

Definition at line 192 of file TEveUtil.cxx.

◆ ColorFromIdx() [2/3]

void TEveUtil::ColorFromIdx ( Color_t  ci,
UChar_t  col[4],
Char_t  transparency 
)
static

Fill col with RGBA values corresponding to index ci and transparency.

ROOT's indexed color palette does not support transparency.

Definition at line 215 of file TEveUtil.cxx.

◆ ColorFromIdx() [3/3]

void TEveUtil::ColorFromIdx ( Float_t  f1,
Color_t  c1,
Float_t  f2,
Color_t  c2,
UChar_t  col[4],
Bool_t  alpha = kTRUE 
)
static

Fill col with weighted RGBA values corresponding to color-indices c1 and c2.

If alpha is true, set alpha component of col to 255.

Definition at line 240 of file TEveUtil.cxx.

◆ FindColorVar()

Color_t * TEveUtil::FindColorVar ( TObject obj,
const char *  varname 
)
static

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.

Definition at line 261 of file TEveUtil.cxx.

◆ GetFraction()

Float_t TEveUtil::GetFraction ( Float_t  minM,
Float_t  maxM,
Float_t  minQ,
Float_t  maxQ 
)
static

Get fraction of interval [minQ, maxQ] in [minM, maxM].

Definition at line 386 of file TEveUtil.cxx.

◆ IsU1IntervalContainedByMeanDelta()

Bool_t TEveUtil::IsU1IntervalContainedByMeanDelta ( Float_t  meanM,
Float_t  deltaM,
Float_t  meanQ,
Float_t  deltaQ 
)
inlinestatic

Definition at line 82 of file TEveUtil.h.

◆ IsU1IntervalContainedByMinMax()

Bool_t TEveUtil::IsU1IntervalContainedByMinMax ( Float_t  minM,
Float_t  maxM,
Float_t  minQ,
Float_t  maxQ 
)
static

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.

Definition at line 346 of file TEveUtil.cxx.

◆ IsU1IntervalOverlappingByMeanDelta()

Bool_t TEveUtil::IsU1IntervalOverlappingByMeanDelta ( Float_t  meanM,
Float_t  deltaM,
Float_t  meanQ,
Float_t  deltaQ 
)
inlinestatic

Definition at line 88 of file TEveUtil.h.

◆ IsU1IntervalOverlappingByMinMax()

Bool_t TEveUtil::IsU1IntervalOverlappingByMinMax ( Float_t  minM,
Float_t  maxM,
Float_t  minQ,
Float_t  maxQ 
)
static

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.

Definition at line 367 of file TEveUtil.cxx.

◆ LoadMacro()

void TEveUtil::LoadMacro ( const char *  mac)
static

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

Definition at line 180 of file TEveUtil.cxx.

◆ Macro()

void TEveUtil::Macro ( const char *  mac)
static

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

Definition at line 168 of file TEveUtil.cxx.

◆ SetColorBrightness()

void TEveUtil::SetColorBrightness ( Float_t  value,
Bool_t  full_redraw = kFALSE 
)
static

Tweak all ROOT colors to become brighter (if value > 0) or darker (value < 0).

Reasonable values for the value argument are from -2.5 to 2.5 (error will be printed otherwise). If value is zero, the original colors are restored.

You should call TEveManager::FullRedraw3D() afterwards or set the argument full_redraw to true (default is false).

Definition at line 280 of file TEveUtil.cxx.

◆ SetupEnvironment()

void TEveUtil::SetupEnvironment ( )
static

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.

Definition at line 54 of file TEveUtil.cxx.

◆ SetupGUI()

void TEveUtil::SetupGUI ( )
static

Setup icon pictures and mime-types.

Definition at line 97 of file TEveUtil.cxx.
